On the 4X i converted everything to 3mm HTD pitch belts, a lot of cars use this like touring cars and most off road cars which are metric ie Yok, Schumacher, Xray, Serpent etc, the belts are a lot easier to get hold of.

What pully's did you use with the 3mm belts.
I'd like to convert mine to use 3mm so its safe to use brushless etc

Would you be interested in doing an upgrade kit as you have the suppliers
;) wink wink !!! :thumbsup:

Its not as simple as a upgrade kit otherwise i would of upgraded my XX4 :lol:

Ok next up is my idea of a upgraded Losi XX4 the 4X from 2008

Photo 1 - this was the 1st proto using a flat CF chassis to make sure everything fits before the mould is made for the tub chassis.

Photo 2 - This is comparing the car against a 501

Photo 3 - The tubbed version of the car, i am pretty sure Simon Reeves and Brian Preddy ran the car, problem i had was it really needed some aluminium parts like the motor plate instead of plastic which flex a lot. And with a XX4 rear end and a Cat SX front end, it would be to expensive to produce a kit as you need two donor cars. But with 3mm pitch and wider belts it was better suited for brushless and lipos.
