ko esprit and lrp speedo help

[jamiew]

Ok here goes hope someone can help have been using my tamiya 502 with lrp sxx v1 speedo and novak 7.5 motor with a ansmann steering wheel set which is 2.4meg.All worked well.

Cant get a long with the wheel so bought a used ko esprit type r in 40meg form.tried to put it in the car but when i plug the speedo in nothin same with the servo some jittering but nothing when u push the throttle forward etc

it wont let u enter set up mode or nothing on the speedo when plugged into the ko but when i plug it back into the ansmann all works fine

the ko reicever is a 297 i think its a old 2 channel version maybe this is the problem??

Any ideas guys
