I think I forgot to mention that I did adjust the two-speed. The speeds I posted are in second gear.

Yep - there are two nitro engines in the background. If I could actually make them run I might be able to put up with the smell, sound, mess, and maintenance ;)
In the meantime they're just waiting to go up on ebay.

The mechanical brake has been okay on the grass and the street, although not as strong as I had hoped. Once I try it on the track I'll have a better idea.
Two things that make it less effective than I'm used to are the speed of the truck and the weight distribution. With so much weight up front I think the rear tires don't have as much grip during braking.
