I never liked the elektri-crap. I'm using long-shanked pinions now.
Castle Neu 1520 on 6S LiPo Powered Gmaxx (Nitro Killer)
Predator with OS .21TM
Supermaxx with Mach .26
Revo with OS .18TZ
Kyosho ST-RR Conversion
Ofna CR with Tekin ESC/Motor (2)
had any problems with the long shank pinions? Do you think the motor mount could be moved forward by drilling new mounting holes so a long shank is not required? thanks
