Thanks again guys.
I put it to the test this weekend at the track (16 hours at the track and ¾ gallons of hard run time)
Other than a couple screws vibrating loose that needed a little more locktite I had no real mechanical issues.
I feel I was slightly over geared/powered for the loose track conditions and need to drop a tooth on the bell and use a smaller carb venturi when it’s that loose.
I tried a smaller carb venturi to tame it a little bit but then the low end snap wasn’t quite there for the 13/51 gearing and 1/10th scale diffs. I ordered a 12T Jammin bell but it’s not vented and I don’t want to run it with a Buku clutch so I’ll set it up with aluminum RC8 shoes I have for testing in loose conditions and see how it works.
With the amount of caster and camber gain I built into the front I’m really pleased with the steering and front grip I get in the corners. It’s a major improvement in handling over the HCR and JT chassis setups. Quite a few “E” rigs running 4S went home broken with their tails tucked trying to keep pace ( score 1 for the Nitro

).
There is 1 high speed jump at the track that everyone including me is having trouble with. I changed rear shock oil and ride height 3 times and still can’t keep it from coming off the lip without the rear kicking up at high speed. I’m going to try the VD pistons in the rear shocks and if that doesn’t work I’ll either have to slow down, or take a shovel to the jump and make it work. I think that 1 jump probably broke over $100 worth of parts on other rc’s in 1 weekend.
The only thing I need to work on for now is the front rpm bumper. The bumper sticks out farther then the front wheels and when I land a jump with the nose down too much the open design of the bumper will dig in and make a big divot on the track instead of sliding over it. I’m going to make a full skid out of ABS plastic that covers the bumper completely and tie it into the rpm wear plate. Hopefully it will skip over the clay and not dig into it (my caddy is getting tired of fixing my divots).
Chassis looks a little different now after approx 1 gallon run time.
