XXX-CR First Run
 

Finally finished building my new XXX-CR today and took it out for a quick bash in the road outside... oh - my - GOD! I haven't driven a RC car for 14 years or so (Procat) and I was blown away by the performance. In fact it was so fast I got a bit too friendly with the kerb and broke one of the front carriers!

I need to tweek the steering a bit, but overall I was surprised that it was doing wheelies with a 7.5T motor. Is that normal or do I need to adjust something with the set up? It was running with the following:

Orion Vortex 7.5t
25t pinion / 78t spur
Trakpower 4900
Novak GTB (basic profile with reduced drag)

With such a high gear ratio and 'sensible' motor for 2wd, I was surprised to be recreating some of the youtube videos I've seen with out of control xxx-crs with stupidly powerful mamba max systems.

Does this seem normal? Do I just need to be a little less heavy with my left thumb?! :woot:

Just back the slipper off a little

Cheers mate, will give that a go.. I assume the ideal point is max acceleration without wheelies then.

Also... is there just one size of schumacher 2wd front tyres? do you just stretch them over the losi wide front wheels or does anybody do a slightly wider 2wd front tyre?

Cheers :thumbsup:

could always use 4wd fronts buddy as they are a little wider

Yeah that could work

Maybe you'll be lucky and you'll get some older narrower wheels, otherwise you have to stretch them.

if you look on ebay i got a load of sets of narrow wheels for my xxx off "munmod" i think it was and they are dirt cheap aswell

here is what i bought

Just stretch them over the wide losi wheels... it gives them a better "flat" profile as apposed to a round one...

The slipper should slip for 2ish yards.... For example, when your stationary and give it the full beans, there should be a "Squeal" for about 2 yards

Im sure someone will correct me if im wrong :thumbsup:
