Already brushless truggies are a nightmare to find. If I were you and I really wanted another truggy to run on 6s 2200, I'd pick up a second hand MBX5T Prospec (epic epic truggy despite being replaced by the 6T now), and put this in it...

In fact, that's exactly what I'm doing.
that brushless conversion kit is sitting in my wishlist at amain waiting for payday, and my MBX5T is sitting in the basement waiting for its new lease of life. Then I'll put the 6T shocks on it and have one of the finest brushless truggies money can buy
Alternatively, there are quite a few buggies deigned for brushless off the shelf. RTR 1/8th vehicles of any kind, I wouldn't touch with a long stick...

Particularly good are the Mugen and Xray...
