please help ....
i think ive got a problem with my core rc transmitter now

, its been faultless untill i fitted it into another touring car ( from a photon to a xray 009 ) with the same motor /speed passion esc , etc ..
it seems like ive got no control over my punch / accelaration , its all or nothing even when its changed from level 1 to 9 , and geuss what it doing the same on my other car thats running the same motor and speedo set up ...

... ive tried rebinding the transmitter and receiver , re set it all back to default settings , and re set all my end points ...
im lost and dont know what to do

, i had my spektrum dx3r for a couple of years and that was faultless ..
