Today at lunch time, wound them up and turned 'em loose.
The P51 rolled about 8ft and took to the air, crashing into our company truck, slight damage to the wing and landing gear leg was removed. It accelerates fast, climb angle was shallow after 14 feet from start point it hit truck about knee level.
Vans RV-6 does not have enough acceleration in a 15ft takeoff to leave the ground. Hand launched real shallow descending right turn as evidenced in this short video.

Model still had plenty or revolutions left for extended flight. Only thing left to do is add the 1/4" rubber bands the P51 uses. Batteries on video quit, only 1 video to show.
The simple design that is on the hobby table is not quite ready yet, it should be ready tomorrow for flight testing, the RV-6 will have a hot rodding session right after the Rubber Band Plane is completed.
Bent the wing and rudder to get rid of the right turn tendencies. After 4-flights + 2 hi-speed taxi tests that came to abrupt halts, the RV-6 is ready for more, no damage...
