thanks folks, i'm running a 8double motor and the speedo 'should' be capable of running an 8 turn motor. i am using tamiya style connectors and they do get warm/hot, should they get hot? so i have ordered some corally connectors and i'll try them, then if that doesn't work i'll try a powercap, would this plug into the battery plug of the receiver? hopefully it will work ok then.
i do have an old reedy 11 double motor i could try.
simon could i be overgeared? my car is not as quick as my old bosscat with the same speedo, motor and pinion? i'm not sure about my gear ratio though. i haven't done any calculations, just bung in what gear i had lying around
