Converting a buggy isn't too hard at all, just depends how much work you want to put into it. I cheaped out on my Ofna 9.5 conversion the first time around and only used a hacked up Maxx motor plate and Associated RC10 battery cups........the motor mount flexed and nuked spurs like nothing, and the battery cups didn't sit flat on the chassis and killed battery bars. I've since made a new one out of 1/4" alum. that will never flex and added Kyosho Twin Force battery trays (part number MA109) to keep the cells in much better.

I run a Lehner 2800xl motor in mine, it's a little faster than the 9L and I keep a fan on it to make sure the temps stay cool, but it sure makes that car boogie!
