OMG this thing is awesome. My buddy is using 5s with the 1700KV Losi motor/ESC. Geared 15/45 and it friggin flies. Literally. The car accelerates sooo hard, overjumping is the problem now. Oh, and on the concrete they should have designed a slipper clutch because it's way too easy to pull wheelies. Each time we'd pull full throttle (stand still or rolling), the buggy would stand up so fast that all four tires would be off the ground, and the wing was the only thing touching the ground. LOL.
I'm amazed. Plain and simple. We kept checking tems often. After 10 minutes total run time; The battery stayed air temperature. The motor was 110 F. The speedo was 95 F. The ambient air temp was cool though-35 F.
Either way this wil be a great vehicle for running our indoor off-road track. That is until the track starts getting hammered, like all 1/8 scale tracks. I can't wait for more to get converted/bought.
