XRAY - Model racing cars

Hi, I bought 4 digital individual weighing scales to balance my t4 properly. I haven't tried this before. When I weigh my car the front left and the rear right seems to be heavier by 100 grams. 100 grams seems to be a lot right? And I also don't want to add more weight to the car cause were buying titanium screws to make it lighter and it would be pointless to add weight. I tried moving e servo and receiver and esc but to no avail there's minimal movement on the weighing scales. Can anyone help

Hi boggsy,

Can you post a pic of your chassis?
I found my T4 is almost perfectly balanced left to right without adding any weight.

Cheers

Hi andrew sure, will post as soon as i get a pic

When writing your post, use the IMG button at the top, then put your link inbetween the two boxes that appear

Boggsy, I must confess most of mycars in the past have been out far more than that

All of my cars have been heavy on the servo side at the front, and the diagonally opposite corner, opposite the motor.

Hi

Can't comment directly on T4 balance, but I occasionally use the 4 scale method to check for tweak on my T2 '12. Some tips:
1. Make sure the surface you are using is perfectly level (use a spirit level to check)
2. Use setup wheels to make sure weights and sizes of the wheels are equal (the plastic rims you show in your pic are probably OK)
3. Check the anti roll bars are not twisted
4. Check that the chassis is not tweaked (loosen the topdeck with the chassis flat on a setup board and re-tighten)
5. Set the ride height equal front and rear


After all that ........recheck. If the corner weights are still out, then adjust the spring seat screws

It is NOT unusual to find quite big differences, and these are usually on a diagonal. (You will be surprised how little screwing in/out it takes to even things out - spring rates are around 250g per mm so 100g = 0.4mm adjustment !). If you screw down 1/2 turn on the left front (for example), adjust the right front up by the same amount so that the overall ride height does not change. It's usually not worth trying to balance to better than 5g difference. On the T3 '12, all 4 corners end up pretty equal - but depends a lot on battery & motor weights.

HTH

Also loosening the shock towers a little before retightening the top deck screws.
