Not man-goo then?
I have concidered wider axles yes- RC4WD.com sell aluminum Madforce axles that I've been eyeing up for a long time- they are about 14" wide I think, so they would give me roughly the same width I have now, only without having to use 2 sets of widers. $99 an axle which isnt that bad really, just have to find some donar original axles to get the diffs/ dogbones/ knuckles from- or buy new parts from the re-released Madforce..
I have noticed the shell is a bit thin yeah, I have drywall tape actually, will just need to pickup some shoe-goo or something similar; just thinking about a paint job at the moment, really have no idea what to do besides a chrome grill & bumper areas.
In the mean time, I've hashed out a plan for mounting the tranny- its so small compared to the 3906 version that the normal method of using L shaped brackets would look a bit messy, like having a shelf sat inside the chassis rails. Instead, gonna do something much like this:
**insert picture here if I can ever find it again**
The tranny is mounted to the centre skid using 4 standoffs, like its on stilts essentially. What I will do is use a sheet of metal or lexan between the centre skid and underside of the chassis ( to replace those little plastic spacers ), then mount the standoffs to that- saves hacking about my lovely NewEra centre skid.
