Here's my MOA 2.2:
It used to be an FTX Ravine, now it's a Ravine Plus.
Pit Bull Rock Beast II tyres, new foams front and rear, home-made high clearance suspension bars, lots of lead in the front wheels and the battery over the front axle.
The tall, light-weight roll cage keeps it from doing dead insect impressions. There are always two wheels on the ground for self-righting.
A complete electronics make-over gives full control over both motors and front and rear steering.
It can even do the wall crawl trick (just!)
The basic off-the-shelf Ravine is excellent value for money. The Ravine Plus takes it to a new level.
