I'd like to see your rear wheel midmotor rally machine. Is it built on the tb03? It sounds interesting.

Yes the geometry of the tb03 is similar to the TA05. But you are correct that it has more rear end stability. I couldn't put my finger on it, but that rear end weight really changes how the tb03 thing turns. I kind of want it to be a little wilder in the rear.

I'll have to try the xv-01 rear arms to see what thats like.
