i no you guys drive mainly electric rc cars, but if anyone can give some advice i would appreciate it.. i run a 1/6 scale petrol buggy with 23cc engine that has a kill switch to shut down engine.. this switch is connected to a failsafe which connects to the throttle servo... my question is.. i have jut bought second hand a spektrum dx2 2.4ghz tranny and reciever, the tranny has a built in failsafe, will i have to discconect the failsafe on my buggy so as to use the one that is built in to the tranny, or will they both be able to work together some how.. any help would be appreciated .. the bink

They would probably work together okay. If your old one protects against low voltage it may be worth keeping it in there. Either way I don't think it will upset the Spektrum one. Just set them both up as normal.

thanks for that ian. will see how i get on with it... cheers the bink
