pinions

so I took instead :3times MaxAmps Lipoly 8000mah 2S2P 7.4V Pack
to have 22,2volts .. (paying takes the whole autumn :( )

22.2V is way to much for a 7XL. A 7xl is better off running on 4s lipo (14.8V) Any more and you'll overheat it.

Sounds like way overkill. You better have one strong tranny. The stocker will explode on that power. They just arent built for it.

To prevent motor overheating I use 2 sets of integy made coolers (INT-c22379x)

answer:
At first I learn of motor/controller sets with
old shumacher club 10 ,no need to last long ;)
and next kyosho RS
The RS has steel diff-gears but it needs metal spur (48dp 75-80th) or same size as 32dp( ???th??)
it has metal Steering Knuckle's too.
Anyway,this car may not see over 15 volts..

Pre-deal is made of used inferno, for real USE. Believe it is needed for full voltage.:eek:

anyway, with 8g spiders-diffs that I already have.
does it need titan pins? else?
