Thought I'd share my rebuild of Lightning. Got lots of info from you folks and parts from Mike.
So here's where I started, Kong tires and Dual HV Brushless
Base truck is a VBS equipped Lightning (first one), it has 8 gear diffs, RacerX, setbacks, a monoblock, dual servo savers and 8mm CVs.
This setup gave up the ghost pretty quickly when presented with 3s Lipos.
On to bigger and better things I ordered a Tekin RX8 a 1350kv motor, Mike's Slipperential and universal mount.
And here it is today
It's got some tuning to do, but the thing rips. It's running on 6s, either a single 3300 or new pair of 3s 5000 and a 16T pinion.
