Try to run it lightly to see how that work man!

if you are careful and don't wheelie a bunch they might last for a while. i think the worst thing for the diffs is punching it from a stand still.

a spool is bad on higher speeds. Doesn't help the truck to get stable..

the spools are in the truck now because i blew the diff cups with a dual HV-maxx setup.

would the maximizer cups with RRP gears hold up, or should i save up for UE or hibrid bulks........

My 7075 cups are still going strong. They are nog as tough as the UE's but on the 7XL they survive quite well.

shim the properly is my advice, and maintain them every now and then. And use aluminum housings or the new 3.3 t-maxx housings. (they use more screws, which makes them more stable)

If you can, go for the combo bulks instead of aluminum housings. After cases and bulks, it comes to about the same thing...

i already have alu. bulks so it is a no go on the combo bulks. should i get the traxxas ring and pinions or the RRP ring and pinions? i dont want to be in the same situation like my buggy was by ripping the diff apart every half a run.............

I would go for some RRP I guess...

well i ran my maxx today and i am very happy! even with spools F/R it handles better that my brushless LSP. it is also faster and lighter by 1.5 pounds!

my setup now:

custom chassis
9xl
Quark 125B
4 ofna shocks
transmission locked in second with UE idler
alu. bulks
16 cells (5s lipo soon)

i am running 51 spur and 15 pinion. can i gear up? the temps are bearly hand warm now........

you may be able to gear up two teeth and be fine. How's the Quark? Also, are you going with Single speed?

woops, yeah it is my maxx........

What lipo's are you leaning to?

I would go 5s

more important; What brand?

serum, i am going to get trueRC 2s and 3s 8k lipos.

neweuser, i have made my own single speed by removing the uneeded first speed gears and locking it in second with 2 screws and an arow shaft. i'll try and post a pic later..........
