Still using mine regularly ! Actually more often than my regular TC. The car handles good but has a tendency to grip roll. The CG is pretty high for such a narrow car. I have managed to run with a shorty lipo in it but it showed much more complicated than expected. It doesn't fit length wise, so you have to run it transversally. BUT you have to use a belt tensioner to clear the battery. Then you realize the belt is hitting the steering bellcrank. So you have to make another steering bellcrank from scratch... I did succeed but after countless hours of work, and everything still fits with a shoehorn.
If you want to use a BL motor, you'll realize it's too long and doesn't fit in the chassis opening. Of course you have the option of choosing a spur/pinion combo that keeps the motor above the chassis plate level, but that is terrible for the center of gravity. Butchering the chassis not being an option, I had to actually shorten the motor itself. IIRC I found 1,5mm to spare inside the motor, between the winding and the rear part of the motor. And I found another two or so, on the back plate itself. Now the motor can sit at ride-height level. But in my case it took more than an afternoon of work.
I think a modern 4wd mini with appropriate 55mm tires would be much easier, and would perform much better to be honest. Not to mention parts availability. HTH.
I love wedge bodies. I love dish wheels.
