Nope. My S1 went together nicely. Are the "holes" just not lining up for you? Make sure the motor mounts are mounted correctly on the chassis.

FWIW. This is fixed after: alum. wheel hexes, DCJ, and Tamiya low-friction ballcups (they are smaller so they are not as close to the belt.) I think the alum. hexes were the big thing, the wheels were wobbly causing the whole front to vibrate.

The wheels are not touching anything at full turn, I have a few mm safety margin.

Maybe this is just overkill, since when do you have full throttle with wheels turned fully?

I am breaking a lot of C hubs. Today I broke 3 altogether. Any other brand works and is more durable? Also thinking of putting xray front arms at least on the car.

your best bet would be stop hitting things

better to have plastic c hubs, if you go aluminium you will probably break the arm instead if you crash hard

Nah I never break anything in my xray which is a stock 17.5. In the spec r with a 25.5 I am breaking things which should not break. I am thinking the offset wheels and extra weight of the VTA car sheer the hub off. Reducing offset and tamiya hubs is what I will try else will get another xray to run as vta.

The tamiya c hubs are narrower than the Spec-R ones and will need shims to stop them floating about. Also, they are no stronger than the Spec-R ones - I broke just as many hehe.

So basically they're packaging up all of the improved bits that they've come out with since the introduction of the R1 and putting them in the kit and calling it the Pro-Spec.

Wonder why they aren't including the aluminum center pulley?

Yeah I ordered the tamiya shims and flanges as well from ebay since they were sold out everywhere else.

good that they inclide a thinner chassi as the car is way to stiff with the 2.5mm chassi!
more good that they havent done any major updates, i will go for the other 2.25 option chassi, new b spec topdeck and new motormount for my car
