If I were you I'd give the ofna another go and I'd sell the rd logics to some schmuck on e-bay.
And to answer your original question, buggies are the most durable 1/8 scale r/c's out there. The low weight, and low rotational mass of the wheels and tires keep parts happy.
You've just had a bit of dumb luck.

Pretty much this. The Ultra series uses cheapo cast metal for the diffs. The Ultra line is from Hong-Nor, and while they produce a ton of models, the only GOOD Hong-Nor cars are the Jammin/Nexx series. These are their competition level stuff.
Diff problems have always been an Ultra liability.
