A bit more work on the chassis. Has to remove the brass from under the batteries, because it was making them sit too high for the brace. No biggie, can use sticke. Weights in front/Behring etc to balance it out.A bit of foam spacing to locate the shorty where I expect it to end up. Nice blue brace used too. Oh and fitted the servo and pt too. Used some nice FT mounts. So here it is:

And yes the 1313 might be a bit of an overkill for a B3 but it was what I had spare and there is no harm at the end of the day.
