I would all so recommend up grading to the MTSS clutch bell and bearings which is the same thing as the Savage but get the race CB as it is hardened and vented.
Yes the ring and pinion is a VERY good idea and highly recommended!
Thanks 46u - the MTSS clutch bell is a 15T, so I'm guessing I'll also have to drop in the 47T spur from the 18SS?
BTW the ring and pinion, do you happen to have Tower Hobbies part numbers for those?
Thanks
Matt
