Well spotted. The black pulleys are much bigger than they need to be, I'm going to reduce the diameter of the fences by about 2mm which should give enough room. I only race on large Tarmac tracks so won't need to gear down much more than that.

I wish. It was cut using the good old Dremel! It was drilled using a pillar drill though so the holes are accurate enough for a prototype.

The final carbon version will be CNC cut by fibrelyte

Jigsaw's a re good for cutting large pieces of fibreglass but for the smaller stuff I use a tile saw, very good for cutting c/f as well, nice and quite and with minimal wear on the blade.

Nice to see the car fleshed out, I know the original concept was to have the electronics as tightly compacted as possible but now you can see it in the flesh you realize how tight it really is :O

Just purchased another TC6 off eBay to use as a donor car for suspension/diffs/bulkheads etc. I was originally going to strip my existing one down but with the race season fast approaching that seemed like a bad idea! Used TC6 prices are now very low with the 6.1 out, so this looked like a more sensible option.

I'll post some more pictures (hopefully next week) when it's all assembled. That will allow me to check the front/rear WD, and if it's correct I'll order the belts and make up a top-deck.

So still lots to do... I feel another day of holiday coming up spent in the garage

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)

Wow! Nice work!

Do you raise the topdeck or make it asymetrical to avoid the motor?

The top-deck will go around the motor, but will still be symettrical. Drawing attached. I never raise the CoG of anything if I can avoid it.

Really like how this is coming together ! I will follow the rest of the build with interest.

Looks absolutely amazing. I under stand the advantages of having 50/50 wd and a low cg but it looks like the spur gear is lower then the chassis. did you cut the chassis there to get it to fit in there?

Thanks for all the positive comments guys, really appreciate it

There is a small groove under the spur, it's not cut all the way through as the spur is at the edge of the chassis and a cut would look crap there.

The belts have now arrived and even on their loosest settings they are too tight. I used a calculator from the belt manufacturer for calculating the pulley spacings, then took a bit off as I figured the suggested figures would be on the tight side. Guess I didn't take enough off!

So I need to make a second prototype chassis with the diffs moved about 0.5mm towards the centre of the chassis, to slacken the belts off. Shouldn't take too long; it took about half a day to make the first chassis, and the second one should be quicker.

So hopefully have some pictures soon of the second chassis, with the belts all fitted and ready to go.
