losi xx4 belts
 

I run with a losi xx4.
I have got a problem: I continually breaking belts, especially rear.
Is there a solution?

thanks from Spain

What motor are you running, what are the grip levels like?

I was running a 5.5 in mine and I found slowing the car down to a 6.5 or 7.5 helped me with the rear belt. Also make sure your slipper is adjusted properly.

Setting the slipper correctly i critical. Take a look at this link:http://www.rctech.net/forum/electric...forum-167.html and scroll down to Dynodans post.

I´m running with a 7,5 and the grip is medium (clay).

must I put belt tensioner?

Thanks.

The bearing block for the rear diff is a belt tensioner, you should have two sets of bearing blocks with A and B on them.

A - with arrow pointing back - rear belt tightest
B - with arrow pointing back - rear belt tight
B - with arrow pointing forward - rear belt loose
A - with arrow pointing forward - rear belt loosest

I run my xx4 with the belt tight, B blocks with arrow pointing back.

Try changing the diff and centre pulleys when you fit a new belt.

thanks for you help.

Belt tensioner, I mean page 3 (manual losi xx4, not world edition) step 25-26
