Who has put lipo in there 501???

I'd just like to know, who has fitted lipo in there 501's

If you have, what packs are you running and whether they are hard or soft cased.

Any pics that you may have to add to this thread may be useful for not only myself but others who run this car.

thanks

I will try add some pics if I didn't already. I basically made the bottom of the cell posts on my 501X flush with the rest - grinding a flat basically so it didn't stick out at the bottom into the cells.
I am using the Trakpower 3200 hard cased lipos. I've never really taken them out since putting them in - charge in the car (put the car in a sack! lol)
Putting them in I did notice the difference - in a bad way initially. The rear just became very loose, I was on bald tyres being fair but still. I ended up putting lead down the centre under the rear belt and also on the front rear hinge pin brace in between the belt - this made all the difference, bringing the weight back up and improving the balance, the car is now 'ACE'

I run trakpower 4800 in my 501x. further down the side you'll find another post or two about this, with pictures.

Thanks..

Ps - im guessing that the trakpower 3200's are smaller than the 4800's??

yeah just the height is different. To get an easy fit, I put a 1mm spacer under my posts, could maybe do it without but the pins might be a squeeze

Col,

I have Trakpower 3200 in my 501X. I use B44 battery posts, and the packs are held very securely. It also means that if I can run NIMH.

As far as setup goes, I have been working on it for a while, and have it nearly there.

Pre LIPO:
Front - blue AE springs, 35Wt oil, shocks on outside on tower
Rear - silver ae springs, 30wt oil, shocks outside on tower
Long wheelbase
minimum ackerman.
1 shim under front camberlink brace.

Post LIPO:
Front - blue ae springs, 45 wt oil, shocks one hole in from the outside on tower
Rear - silver ae springs - cut down, 40 wt oil, shocks on the inside of th tower
Short wheelbase
Std ackerman
no shims in camberlink braces
No additional weight

Some might think the thicker oil is a strange decision with the lighter car, however it calms down the lively back end, and the car is pretty much dialled now. But there's always room for improvement, so my next thing to try is th 0.5 extra toe in on the rear hubs (rayspeed).

I might have to try that setup. On my car to regain grip I went to kit yellow springs and 25wt oil in the rear on the standard big-hole piston.
