RE: HPI 18SS piston retainers
Allllrighttyyy then.......being as no one is willing to accept the " I can help you out" prize, I'll answer it myself.
The retainers from the Traxxas 2.5 or 3.3 fit great, in fact better than the original as they have a little more wire coil to hold onto as they are being fitted, and are
less than a quarter of the price.
Gee mate...thanks for the info.........
