The TM200 is finally completely finished. She's hefty at 952ozs but with almost 16sq ft of wing she has a wing loading of about 59.5 ozs/sq ft. The plane has 9 Hitec 7955's servos, a Weatronic dual receiver with a 10,000 mAh battery for the primary and a 4,500 mAh pack for the backup. The wing has 3 control surfaces on each wing half. The inner flap has 2 servos driving it and the middle and outer control surface have just one. There is only one servo on the elevator but the geometry of the linkage is excellent and enought torque is available.

 

Here is video of the maiden voyage of the ThunderMaster 200 at Weldon, CA on 8-6-2009. The first flight (almost) went off without a hitch,...you have to watch the video and see.... Jason Lilly

Watch as four pilots, Spencer Lisenby, Jason Lilly, Bruce Tebo and Chris Bosley fly the incredible ThunderMaster at Weldon California to a maximum speed of 425mph by Dynamic Soaring.  If you watch the video you’ll notice that the radar measurements at the top of the hill were the microphone is only get’s 413mph or 418mph.  The lower speed measurements at Radar Rock for this flight were all higher by 10 to twenty mph because the operator was getting a better angle on the plane.  The video does capture the 425mph lap but that measurement occurred away from the microphone.

The plane has a 200 inch wing span, two 11 pound steel joiners and weighs over 77 pounds. This combination of speed, weight, wing span, 65+mph winds and high speed shear crossing makes for some outrageous sounds. You’ll also notice that the far side of the groove, the lower or far shear crossing, is also incredibly loud.  The ThunderMaster lives up to its name and creates huge thunderous clapping noises.
