Hmmm looks like you got the same motor, i have, just with different "T's"
Sounds like a 10T one
Slash on 5S ? Thats a lot power. how much mA do your batteries have ?
I have 3S 6500mA and get almost 25min runtime Indoor so around 73Wh
A 4000mAh on 5S would be around the same (74Wh)
yep, mine is a 10. I'm running a 5s3000mah 40c zippy.
So, if you're running the same motor, do you also get a minor glitch a very low speeds? When I 'crawl' along it suddenly boosts forward a bit. This only happens with very little throttle.
