DANGER! SLT protocol with fixed ID

I finally found the cause of all my SLT helicopeters crashing out of control. if you have two model with different model ID, you have to turn off your transmitter for 5sec when changing model with different ID, BEFORE you try flying your model, or otherwise the transmitter/module will get mixed with the other ID, causing your heli to crash.

you could also avoid this by binding all your heli/planes to a single fixed ID. or don't use fixed ID at all.
