Ok guys,

I think the problem most are concerned about is the chute deploying in flight. The AUTOCHUTE system that I have designed prevents that from ever happening. I see that Swissflyer is familiar with it. It works off 2 parameters from the radio and ground speed. The flaps, brakes and a wheel sensor keep track off your controls constantly in flight and on the ground when the radio is on. All (3) programmed parameters MUST be met to deploy the chute. If not, it's not going anywhere. Even a radio glitch cannot deploy the chute! Once you program the parameters into the unit, it is ready to automatically deploy the chute upon landing and deceleration to 60 mph. Using the BVM F-100 for example; the F-100 lands at around 70mph (read this somewhere). After touchdown and the wheels spinup the wheel sensor looks at the groundspeed. Once the aircraft's ground speed drops below 60mph the chute deploys. If your jet happens to land at less than 60 mph, the chute will deploy just after touchdown, but only if both the flaps and the brakes are at their pre-programmed position (usually full flap and 1/2 to 3/4 brakes). Also, if you're doing a touch and go (brakes off), the chute will not deploy. The flap and brake parameters are up to the pilot. After landing and chute deployment, and the aircraft comes to a complete stop, the chute is automatically released from the aircraft. The system requires only 2 servos, (any size) and 2 "Y" connectors. No rx open channels are used. The unit "Y's" into the flap and brake channel and uses the radio system for power. Draws only 10uA until deployment. We now carry a spring loaded latch assembly for keeping the chute door(s) shut.
