I know many of you guys & gals have upgraded, but I'm sticking with the stock gear.
I can use any Rx/ESC units, servos, and crystal sets (already have 1, 3 & 5) and mostly, any of those TINY M1.8x4mm TP screws that mount the servo arms to the Perfex KS-11 servos.
I have some Futaba parts and one full Losi Mini-T rig available, just let me know. My eBay feedback is available: whitewolf_mcbride.
