Do people use threadlocker on any of the screws going into aluminum when building the car?

I use a smidge of threadlocker on all screws that are going into metal.

Nope, you should never do that. You will end up with stripped screws etc. just check screws every race at first until they are all seated.

We will need a bit more info like what motor you plan on running and what size spur gear whether it be 48 or 64 pitch to get you somewhere in the ball park.

I only use it on screws that I seldom remove, like the screws holding the bulkheads from the bottom side of the chassis. Stuff that gets removed often (like everything on the top side of the car), no.

Still not the best idea, if the chassis gets a tweak in it you will need to slacken these off slightly.

Note, the stock spur is a 84t spur, not 78, but assuming you have a 78.

Assuming non-boost mode:
TC: FDR for 17.5 non-boost

http://www.rctech.net/forum/electric...l#post11344227


So, you might want to get to a 4.0 FDR, according to a previous Skiddins' posting, we was only able to get to 4.56 (84/35*1.9). Using a 78t spur, which I think will allow you to get to around a 37 pinion (78/37*1.9) you can get to 4.0. If you need lower than 4.0, you'll need a smaller aftermarket spur.

If I were you I would start around 4.4 (33 or 34 pinion) on your 78 spur, then work your way up to a 37 checking temperatures.

Thanks man for getting me in the right direction you are right it is an 84 that I'm running stock so what would be a good size for that to start out with

Yet more racing at Newbury (13.5 open), same layout and track as Friday but this time filmed on a headcam, fastest lap improved by 0.23s, probably due to the extra grip;

Cars 1,3,4 & 6 Are Xray T4's
Car 2 is Awesomatix
Car 5 is a Yokomo BD7
Cars 7 & 8 are Schumacher Mi4's (not sure which variants)

The Mi4's had similar setups though I believe the pole sitter had returned to kit rear springs.

+ YouTube Video
