Finally had a couple of spare evenings to get the car built up with the TC6 donor parts and spare radio gear out of my buggy. The HW ESC is huge but just about fits in (the GM that I normally run is currently in my main TC6). Please ignore the wiring, that still needs tidying.
The weight distribution is exactly as calculated; 50/50 front-to-rear and left-to-right. I'm very pleased with that, and with how tightly packed everything looks. The rear-end looks anorexic compared to a normal TC
The final jobs are:
1. Order the belts. I have a supplier that will cut to width so I'll get these ordered today.
2. Make a top-deck (easy)
3. Make some lipo holders (easy)
4. Fix the pulleys to the layshafts (hard; I have to cross-drill the layshafts as the pin holes have the wrong spacing. Worst-case scenario I'll bond the plastic pulleys to the layshafts as both are cheap and can be replaced as a unit if needed)
