Thanks to Mike@ RC-Monster I've got my mule GTP together. I've installed an OFNA Metal Gear 2-speed with a custom 2 gear pinion, powered by a 1515-1d on 4S-8000 with a CCBEC. Also, using mechanical brakes. I'll be posting pics and vids soon but so far I've only been able to run it at 1/3 throttle. Have you ever seen a GTP wheelie, mine does! Wow, I love the Neu Motor...
