Omerta 2 Wingtips out of the bag
1 March 2014
Jacques has delivered the second outer panel of the wing of Stephane: the finish is superb. Stiffness and weight at rendezvous. Kudos to Jacques! His production rate is impressive and the final product is up to snuff in all departments. Bravo!

Central Panel Bolt Beam - How to install
4 February 2014
As the good old saying goes: a picture is worth a thousand words. Here it is a nice sequence to illustrate how to install the bolt beam into the latest central panels for our ALES ships.
The full sequence is here!!!
eBD full kevlar fuselage pod
30 January 2014
A new BD fuselage is available with a full kevlar layup. These units can be used with Bubble Dancer wings or, with little adjustments, with the newer Omerta wings. As a matter of fact the new Omerta mould was designed with a longer nose than the BD to allow for proper trimming of the airframe, since the first trials came out tail heavy. The BD fuselage is a bit narrower than the Omerta so that it is difficult to install 2500 mAh 4S LiPo batteries in it. But If you plan on using 3S LiPos or lighter 4S LiPos this fuselage is perfectly fine!
So now we can choose which fuselage to use, depending on the aeroplane geometry and radio setup. Way to go!
New ALES fuselage and wings for our 2014 ALES ship: the Omerta mk2
9 January 2014
Steven has cured a new fuselage pod using the mould we manufactured for the Kuda. This time the layup is all kevlar (with the local exception of the pylon area which is reinforced with carbon cloth) and has a canopy on the upper side. Since the original design for the Kuda sported a nose cone, Steve had to modify the parts after cure to create the canopy and its landing.
And, the first wing panel of the Omerta mk2 is out of the bags, trimmed and ready for servo installation.

Paul's BD coming along!!!
5 January 2014
Paul has started building his eBD. As a warm-up he decided to build the horizontal stabilizer first. And here's the result: 19 gr ready to be covered. Great job!!!
Member Cards holders
3 January 2014
As decided during the AGM, each and every member is now required to wear his MATS and MAAC card in a visible way at the field. Card holders will be sent to each member upon receipt of inscription fees. The holder can be clipped easily on your T-shirt, trousers or hat at your best convenience but must be visible at all time.
Please notice that the upper lip of the holder can be taped to avoid any water to get inside damaging your cards, and to make sure that cards will not slip away and get lost!
Winter Flying at Les Coteaux
29 December 2013
Roland and Mario have been flying in the freezing cold this winter. Warm clothes, big determination and a great deal of courage make the incredible happening!!!
AGM 2013 - President's report
21 December 2013
MATS is a Radio Controlled Modelling Club dedicated to silent flight since the very beginning of its history. For many years gliders were made airborne using ground equipment like winches, elastic catapults, hand launch and dedicated tugs. A number of competitions have been run using pure gliders and ground equipment following formats as the TD, SLF and F3J standards. For years the source of great improvement and evolution came from enhancements in structures and from new airfoils. That evolution seems to have reached the best achievable level.
The next evolutionary stage has been set by new electronics: the availability of new radios, on-board altimetry, new battery technology and brushless electric motors have changed the game yet another time. It is now possible to have affordable propulsion set on-board to take off with a very attractive power to weight ratio and to limit the altitude at which the engine will stop turning. In actual terms these new technologies remove the greatest hurdles that the members of MATS have faced together with the rest of RC Gliding community: carrying and installing winches at the field, laying down hundreds of meters of cable, sustaining the tension at launch, retrieve the cable at each launch, and reverse the whole process at the end of the practice day. The need of large flying fields has vanished with the introduction of the new technologies.
Polecat ALES 2K13!
17-18-19 June 2013
The echo of the ORCC crowd going down to Carslisle, PA to fly ALES the last two years in a row intrigued us quite a lot. Plus this is possibly the biggest ALES event of the year, so there is no better place to learn a new discipline than immersing oneself into a high level competition like this one. Therefore we decided to travel down south and visit our friends across the border, and see how our gliders and piloting skills compare to the latest and greatest standard out there.
The flying field was great. The crowd was very kind and joyful camaraderie was the rule! Logistics was impeccable.
Almost 50 pilots showed up, coming from all over North America: from the east coast, including a well populated Canadian group, to the west coast, including a Mexican Pilot!
All kind of different models were present at the event. ALES is probably the discipline with the most varied set of competitive machines, radios, electric motors and batteries out there at the moment. We have seen the most expensive moldies flying together with the cheapest foamies available on the market, with all the range of variations in between these two extremes: home brews, partially home-brews, modified RTFs…you name it we saw it!!!
Etienne has shared with us his pics and aerial views of the contest…
Here you have a picture of the Quebec Air Force fleet…coming from MATS, C2VM and Les Ailerons, quite a few machines out there. Thanks to Etienne for bringing all the equipment in his big van. I cannot imagine how the trip would have been if we would have brought all of that gear in the car!!! As you can see, Omerta was well represented with Jacques and Stephane sporting 3 models of the type. Our Omertas intrigued quite a few fellows on the field. In fact a few times the Omerta outflew the latest Maxa…that was quite a satisfaction for all of us as designers and builders, I reckon!
A few pics of the commercial machines present at the event…
Very well made home-brews…both models flew very well during the whole contest!
And here our pilots at work…
The Quebec Air Force fixing stuff at the field. The boxes you can see were only part of the gear we had with us. We could repair anything, from electrical wiring to main structures. Nice preparation boys!
Unfortunately though, we had to use that gear way too many times during the three days, jeopardizing our final results. The Lesson has been learnt and we are preparing the new material for new year setting reliability as a key criteria in our design choice and manufacturing techniques.
Unfortunately in one occasion, we could not do much to help our friend Bernard. He lost sight of the glider for a moment while the model was a great altitude, when he put back his eyes on the machine he was flying somebody else model…and inevitable happened: a 300m vertical dive that left the machine like follows…
A band of techie-crows gathered around the cadaver to inspect the exposed structure and manufacturing technique. Turns out the Aspire has a sandwich fuselage, which explains the extremely high stiffness / weight ratio fuselage and quite a sturd double webbed spar for the main wing. Sad but interesting!!!
One of the best part of the trip…nice food, conviviality, real time scoring updates and the One and Only Miss Peggy…cooked to perfection by a dedicated crew that kept our bellies well fed during the three days.
Thanks to the whole team for the great work!!!
And here we are, wrapping up the event: the well deserved podium, Deni Maize giving the final speech and asking for the name of next year roast pig to the winner. Nice tradition!
And here we come Montreal…the motor is roaring, while chatting about gliders design changes, reliability improvements, new flying tactics…and passing through one of the biggest storms I have ever seen!!!
See you at Polecat 2K14!!!!
NC Router…Marco's latest home brew
Marco has been working on a CNC machine to build precise wooden parts for his (and our!) gliders. The result is a set of ribs and spars for our next generation electric gliders. Kudos to Marco for this great achievement!!!
Built-Up Stabiliser 22 grams ready to fly!
27 March 2013
After a number of tests the under 25 grams stabilizer has been put to life. A rudder also has been made using carefully balsa, carbon and kevlar. The structure has been covered by "heavy weight" oracover waiting for some light mylar to come in for the next units. More pictures of this new achievement on the Projects page!
Built-Up Stabiliser…the seek for minimal weight
26 February 2013
Jacques and Marco have been working on a light version of the stabilizer for the Omerta project. The first step took form removing foam from a traditional bagged part. The material behind the spar was removed and ribs were added as per the shape of the airfoil. The result was promising but our fellows were not satisfied. Marco then cut with his CNC machine a set of ribs and a full built-up version was created. This one weights only 23 grams, only 3 grams more than a full balsa Bubble Dancer stabilizer. Our boys are still not satisfied even considering that our stabilizer is bigger than the BD design. They are looking at another evolution...have a look at the Projects page for more details!
Electric motor selection
27 January 2013
An interesting website showing how to select your electric gear for applications ranging from basic electric gliders to fully aerobatic monsters. A spreadsheet is also available: plug your numbers and find the best configuration for your future electric plane!

First production Omerta glider ready for radio gear installation!
16 January 2013
Congratulations to Marco who has finished the assembly of the airframe of his Omerta!
Together with Jacques they have finalized the last few details and Marco is now able to install all the radio gear to get to the ready to fly stage.
Brand new Omerta's coming to life!
10 January 2013
A new set of wings and fuselage is almost ready to fly. The bright yellow and orange unit belongs to Duc: with a colour scheme clearly devoted to long distance high visibility, I wonder if Duc is planning long flights drifting downwind for miles and miles! The new fuselage has been painted in the mold before assembly giving a neat finish.
Marco has put a great deal of efforts in sanding, pin hole filling, sanding, filling. . .you see what I mean. . .and the result is brilliant. His fuselage is crystal white and the finish is spotless! Also his addiction to sparkles has need up with a special paint for his canopy, indeed and again. . .brilliant!
Last but not least, the new Rudder XL is finished and ready to be installed: servos are installed and linkages have been routed inside the thickness of the fin. The hinge is as smooth as can be and the overall finish really neat.
It has to be said that the current building technique and manufacturing sequence have been developed by Jacques and then put at profit to all MATS members willing to take advantage of it. Let's be honest, without his irresistible drive for results we would not be here dreaming of enjoying our afternoons at the field and (why not!?) winning the 2013 ALES events with our home made electric gliders!!!
A new rudder XL for Omerta
16 December 2012
An oversized fin and rudder has been manufactured for the latest Omerta ongoing fabrication.
The rationale behind the creation of this beast is that we, so far, always needed some weight aft for balancing. In fact, even with the two servos installed back in the fin, we ended up with ALES ships rather nose heavy.
The new rudder, featuring a surface of 100 square inches, brings some of that weight back there.
No lack of control at low speed with this baby there!!!
30 November 2012
Our National Steve has received some pictures of his youngest steps in aeronautics from an old friend: we are in 1964 and a 17 years old slender boy (wearing black trousers holding the intact model in the photograph) is at the field making his Jasco Nordic airborne. Steve, of course, built the glider himself (not a real choice those days, wasn't it?) with a NACA 6409 as the wing airfoil. The glider flew well and participated to the Nats in 1964! Nice job and fantastic pics Steve!!!
A new mold for the fuselage of ALES Omerta 4M is released
19 November 2012
Steve has finished the new mold for the fuselage of the Omerta.
Get more details by clicking on the picture.
Omerta has taken the air successfully!!!
17 November 2012
Jacques has maidened his newest release of our 4M ALES ship. The fuselage was a Kuda fuselage modified to accommodate the electric propulsion gear. Other than that the airframe was the final ALES version. The flight went very good, showing very homogeneous control response on all axes. Everybody enjoyed the glider in flight and went away motivated for the coming manufacturing sessions!
The fuselage was a Kuda TD fuselage modified to accommodate the electric propulsion gear, keeping overall dimension of the ALES design. The flight went very good: a few thermals have been encountered and exploited successfully. The first flight saw a few climbs with a LiPo 4S and a 12x6 prop. Further flights have been done with LiPo 3S and 13x8 prop. In all case the glider showed plenty of capability of getting to the required 200 meters of altitude in way less than 30 seconds allowed by the rule. Way to go!
A bit of work went into the settings for throttle and brakes compensation. Other than that, the glider felt as a good old friend immediately: it is comfortable at any speed and even if the flight test team tried hard at putting her in trouble we could not do it! No bad habits like tip stalls or such appeared, and landing seems to happen at very low speed and always in great control.
Pylon racer master 3D printed
14 October 2012
Marco is working at the newest of his fast pylon racers. The fuselage has been modeled in 3D and when the design validated a 3D printer has printed out the master. The precision is outstanding within 0.001". The parts are also surprisingly hard so handling the master while creating the mold and actual mold edges should be rather good!
Since the limitation in size the tiny fuselage has been split in pieces. The parts have been glued together and, as you can see from the pictures, the final coating is being worked on. Stay tuned for the pictures of the mold!!!
eBD dancing with the Moon!!!
9 October 2012
A beautiful day out at the field in a clear and chilly day of october with our ALES models thermalling out of sight!!!
QuadroCopter over the MATS flying field!!!
30 July 2012
Stephane has been flying his QuadroCopter for a while and things are perfectly working now. He can stream the video as he flies together with flight parameter as speed, altitude, current, energy left in the batteries. Almost ready for FPV!!!
News from the MATS field
Our members have brought to field and enjoy their gliders at the field!!!
Horst has flown quite a lot lately and shown his improved skills at the field. He enjoyed his full composite Allegro and his Bird of time.
Stan joined the group with his full house TD machine, the Fazer! Great job guy!!!
Keep it up!!!
Quadrocopter flying at the field!
15th July 2012
Stephane has been flying with his Quadrocopter fully equipped! Have a look to the video of the flight!
A new project has been launched!
A new ALES ship is being worked out by MATS members...have a look to the new 4M electric glider coming out our men' cave: the OMERTA!!!
Sunday morning with the fleet of Kudas at the field!
1st July 2012
Duc, Steve and Jacques have flown the Kudas enjoying a very nice morning weather. Tuning is going ahead exploring different CoG and tow hook positions, as well as flap settings!
A 3.8m Kuda has been maiden. Let's have a look!!!
A variant of the Supra Kuda has taken the air for the first time and has performed well.
20 June 2012
Duc has built a 3.8m wingspan Kuda. The fuselage and tail group is the same as the 4m version but the wing is slightly different. The central panel has no dihedral and integral hinges are on the top skin for the ailerons. The model flew as expected and will be sported at this year TD contests.
11 June 2012
Marco has taken out a brand new Dart XL testing a new propulsion set powered by a 6S LiPo battery pack. Here's a log of his ESC: the motor develops 1500W at 80A.
Marco uses a very accurate technique to estimate the speed of his delta. He takes the soundtrack of a video and, using the theory of the doppler effect, calculates the speed of the Dart XL. The numbers are impressive, the speed ranging up to 150 mph!
ALES models are being built at terrific pace by our members!!!
Right away a new ship is added to the MATS fleet of ALES electric gliders.
18 June 2012
Have a look to the new Projects section of the MATS website!!!
14 June 2012
2012 Flying Season has begun!!!
First flights at the MATS Flying Field
A small group of temeraries have defeated the cold weather and joined at the flying field at Les Coteaux for the first flights of the season. It was very windy, at moments stormy, with some bumpy thermals but no clear pattern in the sky. Nobody was able to stay up there for long periods of time, but it was great fun altogether!!!
Our pilots were sporting some full house models (Aspire and Kuda 4M) which were winch launched and some electric powered models.
Jacques took the sky with his new eBDJ, a brand new electric glider based on the Bubble Dancer design specifically tailored for ALES competitions. The ship sports a MEGA 3S motor, which proved to be very powerful. The model behaved really well: it is a RES ship characterised by a wing span of 3 meters with AG airfoils; a modified BD fuselage and custom made tail feathers. Despite the lack of ailerons the glider was able to roll rather axially, making the ship able to fly very well altough the very strong winds.
Different variants of the Drela's BD are coming out of the men' caves of the MATS pilots: Stephen is in love with "V" tails and he is going to install it on a built-up wing.
Luca is assembling a creature that Steve put together with a a build-up wing (winch proof) and a custom X tail BD fuselage.
We also had a new entry in our Pilots ROASTER! His name is Luka and he has proven to be a fast learner at the sticks of the Aspire of Luca, who was coaching him for his maiden flight. Welcome to Luka and we hope to see him out there again soon!!!
Last but not least, Jacques enjoyed the public with the flights of his F22...the hilarious take offs from the ground...and the unplanned "finale" which consisted in a crash...I am sure it is already being repaired and will fly again soon!
See you out there!!!!!!!!!!
