Good job Tony  .............these chassis do benefit from a little bracing.

I can't see from you pic., but one of the weaker parts of the chassis is the rear motor mount......it typically flexes causing mesh issues. and coupled with the fact that the front motor bracket does not do a marvellous job, a rear motor bracket brace is a very worthwhile mod.

An easy effective mod for the front bracket is to place a small blob of ShoeGoo/E 6000 around the front blind motor bushing and the bracket bushing hole.....being a "blind" bushing there is no fear of getting of the glue into the bushing itself......this will help secure the motor and will reduce vibrations/noise.

Here is the simple mod for the rear motor bracket,..........not sure by the pic. if you did this.
