i have a rc10GT RTR and i was thinking about upgrading to [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXPB37&P=0]THIS[/link] high torque servo. Is this servo good enough and a decent upgrade or should i keep the servo that came with the car?

i'd stick with more well known name like airtronics or futaba, it 'll help u out if you need a part

Get something like this if you want a high torq servo [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXUZ89&P=7]http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXUZ89&P=7[/link] or you could just keep the one you have if your happy with it.
