I ran my TC3 for the first time sense I milled the chassis and did the battery mod. I have to say it made transitions much better. It turned the same left as it did right. on the scales it balance out side to side perfect 13 oz's on each back tire and 11 oz's on each front tire. I think I got the most added performance
out of the battery mod than any other mod I have done. If you have not done it I would highly recommend it.
As for the spool made out of delrin it broke an ear of the first time I nicked the wall. Carpet plus foam's plus 2 by 4's plus tight track = a lot of broke cars. We are going to make the spool's out of aluminum and try that. I ran the Robinson aluminum diff after breaking the delrin and it does not give any. It transferred the force to the bottom of the front hub and broke
at the screw. The plastic diff seamed to be the best for me on that track. If you hit the boards hard it would just push the dog bone out without breaking any thing, I liked that a lot better.

Driftmaster, I've been using the IRS spool since it came out (Dave Irrgang is local to South Jersey so he brought the first batch to the track for us to buy....gotta love it...) and have had ZERO problems with it and I have run it both inside and outside, with some nasty hits....I know the IRS is probably the highest price, but it is well worth it in quality....

i was curious what is the best way to initially scale a car? take the shocks off and then add weight to chassis to get it fairly equal on all four corners?
then reinstall the shocks and fine tune with the shock collars (for threaded shocks)
what is a good bias to have? 50/50? 40/60? etc...

Smile FTTC3 Balance

I just made one thing to change the balance. I scaled my batterys and here it come:

SMH3000 360g

HV3000 370g

GP3300 390g

I desided to use my TC`s extra weight with my HUDY`s center chassis weight ( i used two of them normally in my T1 ). I drill two holes (almoust center of the chassis) near to my LRP V7.1 esc to right side of chassis.

Put that bigger 20g weight inside chassis and smaller one 10g outside chassis and tight them with two scruw, and thats it. They are wery tight and i don`t think they fall off easily.

Rest of them (20g) are locedid rear, motors side block, so now balance is near wright (or better when use HV`s or SMH`s) when i use those GP3300 how are heavier than others.

I look Juho`s set-up when he drove last DHI-cup and he put 50g extra when he drove GP batterys. I made it that way because i use piece of lexan top of the servo ( transponder is safety place than outside chassis) and can`t put leads on the top of servo wright now, but maybe that is better....i think

Btw: My tweak tell the same - it`s ok now

Hey North,
What I do keeps me in the ball park I know its not right on, but its close.I went to office supply store and bought 4 16oz postage scales, $5 apiece. Get your car RTR and place a scale under the center of each tire. Lift the car up and down a couple of times to make sure its reading right. Check your scales also, zero them in. Like you said use the collars to fine tune. I like 40% on the front and 60% on the rear.

when i clean the bearings in my car i remove both seals then put 4 or 5 of them in a small tube filled with motor spray and seal then shake for a few minutes then rinse and repeat then spray each individually with motor spray and blow out w/ compressed air and lube with trinity royal oil. and replace seal ( i only run outer seal on hub and diff bearings)

Thanx for the info,
Making some out of alum tonight. The only thing is I feel like
it will wear faster. It will be better then breaking.

Mike,

I've seen many ways people clean their bearings...do you or anyone else want to give a step-by-step how-to on this, I am still pretty new (about a year + half into racint) and I am not sure if I am doing it right...
