Ive not looked through all the posts... but i recently dropped my Esprit 3 transmitter and bust the steering stick... i managed to glue it up to finish the meeting but the car felt " wondery "
Anyway spoke to Derek Bailey who supplied me the parts to fix and he said make sure you do the " adjust VR " which sets up all the neutral points otherwise if you dont the car will feel like its wondering..
Just a thought.. as it cured my cars antics.. initially i thought it was a loose servo saver!
Cheers
