hi all just after some info really. i have a not the worlds best nitro car i know (Smartech) was given to me so not complaining. the thing is the engine is a gonna and i have bought a nitro star .15 to use with the car, the only thing is i dont know how to get the engine to drive cogs on the smartech body. what parts would i need to connect the engine to the drive cogs? sorry i am fairly new to all this. any help would be much appreciated. many thanks

drive cogs? you mean gears? take pictures so we can help, might want to ask in the nitro on road section, not the hpi section
