please help
 

hi have a prob with some sanwa radio gear i think, steering is fine, throttle, i cant seem to have any signal from the throtle stick, i have used a dif rx n tx to make sure not the esc gone. but if i swap the sterring and throttle around the motor will run off the steering on tx if you get me? also the motor will run off the aux. but the left stick on the controller doesnt seem to do anything at all. the rx is sanwa rx-311 and tx is gemini-ll so they do work together, would be nice to get them working as am having to use some cheap hpi gear atm. anybody got any ideas? i have had a play round with the settings on tx and it makes no dif, (btw im not to cluedup on them) but any help would be great. thanks ian

have you adjusted the trim control for the throttle? or the end point adjustments if the radio has that. some times new radios everything is set to zero and you have to add end point adjustment from 0% to 100% full throttle.
all digital radios have that feature.
