I've run my 1717 on 5s and the 35C packs were to warm for my liking even tho I was geared for 38mph in my XXL. The packs got hot and swelled a little, they recovered but The 1717 was to much for them. I would seriously consider useing no less than 40C in 5s, higher the better(Nano 50-90C?) . 6s I think is the basic sweet spot for the motor, It's a amp hungry pig and on 6s the packs stay ambiant temps.

You have to figure AT LEAST a 1/4" for tire balloning, 0.1 aint enough.
