Just trying to help.

The age-old belt vs.shaft question.........Shafties are strong, but no stronger than anything else. They are, however, good for filthy surfaces.

Just one thing on that - Drift vids you'll see on Youtube, those guys sweep or otherwise clean the surfaces they run on, before they shoot the vid, and drifters should be running on clean surfaces, anyway, because their tires would definitely work better.

I'm personally a belt guy, because they are smoother, and I don't know who you talked to, but belts do not require a lot of adjustment. Maybe they confused belts with ball diffs, which do require periodic adjustment and maintenance. Belts do require a clean surface, to be as efficient as possible, and are smoother at putting power to the ground.

As far as which is "better," I don't think anyone can convince anyone else that one is better than the other, so make a choice, and see what you think.

EDIT: On your last Q, the Ofna's are rollers. You won't be putting anything together, except installing the electronics, which you should learn, anyway. I say give them a shot. They are very good, inexpensive chassis that will serve you for a long time (until, that is, you want to progress to something more expensive). Oh, and the Losi drifter is discontinued. If you find one, you will have to get spare or replacement parts from the Losi Parts House, only. My JRXS-R is like that.
