It was mostly onroad i drove it, due to lack of parts, this was before the re-introduction. This particular truck was bought off Ebay from Promod, Most old school MT guys will know that name. This one has a New era Long wheelbase chassis and a center diff with buggy diffs, seemed to handle the power nicely, but never pushed it. I broke the right rear housing at the knuckle and plan to get it running again. Even with a leaking diff it would slam the wheelie bar hard and run close to 45 easily.

Back to the 16018 though, I was using a eagletree 100 amp micro data logger,and logged a few 120+amp runs with around 2600watt peaks and the MGM never broke a sweat. The gearing was buggy diffs with a ofna diff (I think) a 51 tooth plastic gear, the one used by most strobe slipper setups. I was using a 19tooth Monster pinion on the motor. here is a BrianG setup showing the setup

As you can see it was massively over geared and the MGM never broke a sweat, Most runs were around 5-10 minutes. I wouldn't mind running the MGM's again but the expense and the lack of U.S support make it almost not an option
