Thats good to know in case anyone else is considering the same kind of conversion.

I had a set of Tmaxx diffs in GA bulks that already had the UE towers, mount and wing. After being here a while and doing some reading, I didn't think Tmaxx diffs - even in GA cases with flm cups would handle the neu power to come - reason for chanigng to the the hybrids. Was kind of a surprise for the UE stuff to not fit.

I was going to convert my E-Maxx and as its wound up, I'm building a new one around the extended chassis, hybrids, 125b, neu, cvds etc.
