About the video: SS Bipe scratch designed for AP and on board video. Equipment as well as the 2 Slow Stick Kits is twin 21 Brushless Outrunners with Aluminum Stick mounts swinging 8 X 4 props in Tractor/Pusher Config, Twin 15A Esc, 3S 3100 Polyquest Pack, Carbon reinforced wings at 4-1/8" CG point on both wings and at center rib LE to TE. Carbon reinforced Tail feathers at hinge line on Fin and on front of Stab, 5/32" LG and 3" wheels, Hitec 5 channel RX and Hitec HS 55 Servos. This setup will give me 42oz of thrust. I have designed the camera mount for the tripod socket which will allow straight ahead video and pics without prop interference and side angled AP shots. Wing Supports are 1/8" X 1" aircraft ply with single 1/4" balsa center web on rear support and 1/4" balsa box on front wing support and diagonal 3/8" square brace from lower rear wing support to upper front support bolted to aluminum fuse top and bottom reinforced with basswood epoxied inside tube. Thrust correction will be 4 degrees for both tractor and pusher. Camera is DC ISONIC DC520 5.2MP which will give me 5MP pics and 640 X 480 - 30fps full motion Mepg 4 Video for up to 30 minutes on the 2G SD Card. AUW for setup is 52.6oz which gives me a trainer like wing loading of only 7.49 oz/sq ft which is a piece of cake for the Bipe wings and is heavy enough for handling some wind and should cut down on float.
Update:
Added wing struts and flying wires and enlarged rudder & fin. Plane responds great to controls even at slow speeds and in wind. It is rock steady and flys like it's on rails. Plane far exceeds my design expectations!
