Thanks for your input guys,managed to start on those settings but tried running..throttle wouldnt shut off,slammed into kerb bending suspension shaft,engine coninued to rev high. When i operate controller with engine dead, servos seem sluggish,brake not operating,pull throttle slowly linkages move then stop half way,wont open fully? Also,steering not responding whilst running,sluggish with wheels off ground. I'm new to this guys so your advice appreiated,thanks . Just had look at other posts re servos,could be bad servo?? My batteries are good.Fool me to buy used off ebay eh;-(
