Got the Revo.
I've run 2s2p A123, 2s2p Evo 20 1500, and 4s A123. I like the speed I get with 2s2p lipo but want a bit more punch. I will probably gear down a bit with 3s2p lipo's.
I have also run several differant tires, stock (of course), HPI Ground Assualt, and HPI super nitro rally. Ground Assualt's are my favorite so far, followed closely by the stock.
The rally tires(on HPI mesh wheels) feel like they need softer springs and/or shock oil for off road use. Any little bump or rock really upsets it on gravel. They did ok in grass but the short profile lets them down. On asphalt they flat out rocked. Very hard to roll it over around corners even with a high ride hight.
The Ground Assualts(on RPM Talons wheels) are great in the grass, size matters They work good on all surfaces but will roll over quite easy on asphalt. They also don't look as goofy as I thought they might, the guys at the LHS were digging it
Wish I had some buggy tires to try, I like the GA's enough that I dont want to shell out for new tires and rims just yet. Would also like to try Trac-Ta-Gator's they were awesome grass tires on my 1/10 scale stadium truck.
I just rembered I have a set of Road Rage 2.2's on HPI Split 5 wheels, I'll give 'em a run at some point and report how they do.
The truck itself is awesome, it's what I had hoped the 18MT, Mini Quake, MLST would be.
Not to keen on the electronics, Quirky ESC with limited adjustability and capability. The TX/RX, battery, and charger were donated back to the LHS before I left with it. Servo and motor are ok so far. I'm sure at some point a MG servo will be wanted, as well as a decent ESC and possibly a Neu motor. Would have been nice if Traxxas had teamed up with CC for the power system again. Knowing what I know now I would have been happy to pay an extra $50 for a Castle/Neu 1110/2.5D Sidewinder ESC combo.
