Reverse gear

Full reverse please....

This little board is responsible for good landings on short runways. It's the interface between the throttles, the reverser switches and the Simkits I/O adapter.

The problem was that real Connie thrust reverser don't work in the way it is needed for the flight simulator. If you pull the levers in the real airplane, then the propellers go into reverse pitch and the engine power is increased to approx. 30%. That means the propellers blow backwards and the throttles open up the more you pull the lever.

If you connect that directly to the flightsim you will get a problem. The simulator doesn't know if he has to reverse or accelerate, a movement of the throttles disables the reverse mode. The result is a wild switching between forward and reverse thrust if both commands are given simultaneously.

This little relais board does something simple. It disconnects the throttle potentiometers as soon the reverser switch is activated and the movement of the levers has no effect anymore. If you pull the levers, you will get that amount of reverse power as programmed in the flightsim.

Many thanks to the guys at for helping me to solve this problem.
