Part of it is the fact that an 8 scale doesn't rotate if you go too thick.

New to drilling Pistons, what are the drill bit sizes to do 1.6 and 1.7 holes?

Back from the race, the car was great, but as usual it took me a while to learn the track. I qual'ed 4th which is my best result in a long while, usually I make the bottom of the A or the top of the B, but this time I had a bit more luck than usual... until the mains. I broke in the first one (FHS3x6 went out on rear block grrr) and got taken out in the first lap in 2nd one and had to start from dead last, I could climb back to 6th or 7th but not any further.
The car is surprisingly stable for a mid-motor design. the std 4deg rear toe plus 0 deg antisquat adjustment certainly helped. I did feel it hurt the mid-speed turn right before the straight though as I was kind of understeering there and it costed me a couple of tenths every lap as I couldn't throttle hard at the beginning of the straight. I didn't dare change it as I was too worried I'd lose the rear, although hi-grip, mid-speed corners is where the car should shine by design. I also went up from 4K to 7K in the diff and the car was better everywhere, esp. at the hard braking at the end of the straight (hairpin) where I didn't have to tighten my buttocks everytime I tapped the brakes. One of the other guys I was running with tried to move the pack to the front and he said it was undriveable there. Overall, nothing to complain about, the car worked beautifully for me. A bit more luck would have landed me a top5 finish probably. I just wished I had more wheen time and a track to practice at
Just one Q though - I ended up adding 50g under the lipo to settle the car down a bit, and it worked beautifully handling-wise. However, as it lifted the shorty by about 1.5mm or so, I had to file the "fork" of the battery holder so it could fit under the waterfall brace... that was a bit of a hack, really. Any elegant solution you folks can suggest?
Thanks!

I practiced with mine yesterday for a while, it drove very well, I am running the EOS setup but without the brass bulkhead and with only 25g under the lipo. Buggy was great, I had the wrong front tyres on so it was pushing a bit on high speed corners (strictly tyre issue, other people were also struggling) It was amazing with a ton of steering through the tight technical sections, the buggy simply went wherever I wanted it to go. The lightweight buggy was a rocket down the straight with a boosted 8.5 compared to the 6.5 I am running in my XB4. This was on medium grip carpet.
I also had a series best finish for my 4wd XB4 '14, we went all the way to a full C main and I qualified 3rd in the B, but a early mistake led me to finish 4th in the B. Still happy with the results as the A main (and some of the B main) were filled with National level/team drivers.

Where did you get the 50gram weight?
