Thanks for the pic. So I understand this right I would place the pivot ball over the pin so when I rest the car on it, the car should balance. My car already has the holes in the front chassis and the rear pod plate.

If your pan car already has the holes which most do, then yes just use the balancing pins to 'balance' the car. The Hudy and other models all work great and complete the task just fine.

fwiw
I've been running the TQ Booster for about a year now
No issues yet, from 6.5 to 17.5 with a Tekin RS
Tried a rec pack and saw no difference in punch or lap times.

The car is also equipped with a Futaba 4PK fasst system, and bl digi servo.

Adding it to my schedule. But no motor timing in the limited 17.5 class? I'll need even bigger pinions.

Default Rollout relationship between 4NiMh &1sLipo

Sorry if this question has been asked before, but here goes...

When converting from 4cell NiMh to 1cell Lipo, most people will have to re-gear to achieve a different rollout. The general formula is to add about 10mm for the same motor for this conversion. Eg: For a 10.5R motor: 4NiMh set @ 50mm then 1S Lipo will need to set @ 60mm.

Now my question is why?
Is it because the car is lighter, so that we can re-gear another 10mm of rollout without an increase in motor temp?OR
Is it because the voltage is less, so we need to increase 10mm rollout to match the speed of a 4cell car?

Sorry I am a little confused on this. Can someone please explain to me on this? Thanks in advance!

I have a 12L3 with the 4 cell chassis (broke the original 6 cell one ) how do I convert that for lipo? Ideally I just want a single one that runs across like stick pack but will that be possible or will I need to stick to the saddle pack conif? Thanks.

Since just about every 17.5 motor has a different timing value at the 0 mark you should rethink the timing on the motor part...

easiest if you place the lipo on 1 side and esc, receiver on the other side.

Its because the power is slightly lower (even with reduced weight) so you need more gear for the same speed...

at IIC they had a limited 17.5 class? did it restrict sensor position on the motor or only ESC settings?

it would seem that a 'locked' motor rule should rule out some motors with some fixed timing?
