Wow! Nice rig man. That's what I'm kinda working towards. I've had my eye on the hobbywing 2600kv. Did that fit directly to the motor mount? Or did you have to modify it?

Thank you! I have the adjustable mesh mount from HR as well as another motor set up with the adjustable mesh mount from Arrma. I just changed pinions Friday and am now running 27t while keeping the other rig at 25t. The 27t required a slight bit of tooling to get the mesh just right. Everything else bolted up nicely on the stock mount without modification.

I've tried alot of different motors.cheap ol 4068-2650kv is my favorite one.lightest 40mm ,torque, no overheating,weight becomes the problem quick,...HEAVIER esc, motor, batteries,then you'll need HEAVY SHOCKS. Next thing you know you got a heavy powerful rig that performs like crap. Save weight wherever you can. I run a really light 4s packs to same weight.BTW the h-wing 2600kv is also a 4068.
Surpass 40$ h-wing 100$ ran 78mph on 6s with one of these motors on 26t.STILL HAD MORE,80+++
