b4..balance chassis on 1 side with lead?

[dave g]

got all my electrics in the b4

losi excelorin
orion 7.5 sintered motor
spekky micro rx
amb pt
trakpower 4900

weighed it and its underweight,but also quite a bit out on chassis left to right balance...normal??

i use a 6mm wide stainless bar to balance it on,levelled on worktop with same results on 4 worktops,the chassis is heavier on speedo side.

if i add 50 grammes at the side of the receiver it brings the chassis back to the chassis being correctly left/right balanced

anyone else finding this?

Thats how I did mine Dave, and try and get the weight up front. It will work a lot better with some weight over the nose

And don't forget, pretty much everyone runs Heavy any way. No need to try and be Light.

The Power available nowadays with the Brushless motors and the ease of delivery with Big Mah LiPo's take all the worry of dumping away.

And being a bit heavier settles the skitishness of them.

car was fine on sunday for the final when i had got it sorted on setup but i had been struggling a bit on left handers..i wonder if the weight balance issue was stopping the car rolling as much on that side hence why i struggled a bit..guess i will find out this weekend

I thought you were an 8th driver now Dave, not TC.....

[dave g]

even us 8th drivers like things to be right rich

just making some thumbscrews now and all done for weekend.

i also made a nylon bar that runs across the rear of the battery as the 4900 is too thick to get the battery brace under it,so i cut some 2mm nylon sheet and used the rear brace bolts to fasten it down so battery brace goes under that,with it being nylon its flexible too,trimmed the end off the battery brace and all good.

Dave,

My TP 4900 fits lovely...

Thats in the FT with Carbon Strap

[dave g]

mine does if the battery is forward..if the battery is back with lead under the battery it wont fit,im using stock plastic brace.

what ive done is removed the 2 ae front brace bolts where the 2 body clips go thru,then screwed some 3mm rod in there,slipped a 5mm spacer over the thread then the battery brace as normal,this way the thumbscrews bottom out on the washers and dont try to bend the battery brace with the taller battery.

if i decide i dont want to run with lead under battery or run a thinner battery i just remove the spacer.

[russmini]

Ah... You run with Lead under it. I don't...

I've placed mine elsewhere.

[dave g]

well ive only run the car twice,not ran it since the lead added or chassis balanced.

just going to blow the dust off it now

[russmini]

Where you racing Sunday Dave ?

Be good to see you peddling a B4 rather than a 8th....

[dave g]

players...gulp!

[russmini]

Ohhhh, so your going in nice and easy to start with then....

Good Luck
