Weight
So I have been trying to add weight to get my cars faster.i used wheel alignment weights on an 850 as it has a lovely roof to put them on.i know this wouldn't be acceptable in a race but saved me taking apart and trying to find spaces,this gave the 850 another 2-3 car lengths on the car I was racing it against. I've tried with another car but it just seems to make it slower. Might be the case I send car as is with just graphite.are there certain cars which do not want to play. I saw a recent video on utube where the builder added weight and it was mad fast.i also have no timer system to help other than phone which is not good enough.ive entered a competition where you can win $100 of vouchers for spool heads so if I get lucky there then I'll use that and pay difference for postage...

Avoid tungsten putty!! That path leads to disaster and disappointment without specific care. It can ooze away from its initial placement and gum up wheels/axles
Steel balancing weights are not as easy to work with compared to lead and lead's higher density means same weight added at lower centre of gravity. Only offering facts not criticism
- Thankyou,just strange that it worked well on the volvo but not the other one — RalphsRacers
- Yeah one technique may be suited for one casting on one track then not do so well elsewhere. Lots to consider for each build! A record setting car could still find itself uncontrollable or too fast at another venue, and there's the role dumb luck can play — Chris_Hood
- I have an inventory of supposedly 7g wheel weights but they barely weigh 6. A nickel is 5.0 and a quarter 5.7 while requiring far less space. — Ruckus_Racing
Try golf club weighting tape. It's called lead tape, but doesn't use lead anymore. It's made with tungsten & It's VERY heavy & can be cut to size & layered.
- Will try thankyou — RalphsRacers
- Good call on the golf tape. — SpyDude
- Hey, that's a cool tip about the tape. I still have an old package of the leaded stuff laying around. I would have never thought that you could get it in tungsten form now. Thank you. — X2Whiskey
I add more diecast using 190° low temp casting alloy
or, brass strips drilled, tapped and screwed together
but, as people will attest, my cars are a bit different
American diorama girls add 5 grams each
the gasser at 905 has a 15g cast parachute
22 grams of girls here
(FYI, I am the reason for the bikini rule...lol)

- OKay, we need more pictures of the girls! — SpyDude
- They look brilliant, — RalphsRacers

So,I bought golf tape from amazon.no luck.the cars are reasonable speed,probably won't get past round one but will send anyway
I saw on utube a man got a mold of interior and then made it from lead instead of plastic.added a lot of crammed,said it did really well but didn't show a before and after might try that before entering anymore races
