Revo ?'s

Thanks for the info, how about the BL e-revo tranny?? is it a direct drop in for the revo 3.3 chassis, would it accept a regular revo 38t spur?? also would it line up with the RCM brushless mount for the 3.3?? i wanna replace the diffs and tranny with the ones built for the BL erevo, other than that the driveline is bulletproof
