I just moved up from a Castle 1410 3800 in my SCTE 3.0 to a Hobbywing 3656sd 4700kv.
The castle was a *great* motor and not exactly short on power. I had finished several A-Mains with the win and without crashing, so I decided it was time I could use a bit more. I saw a few people say the 4700 was too much.
I didn't listen. It's alot of motor. *alot*. I'm crashing more and overshooting jumps. Will take a bit of time to get used to the extra juice. It also demolishes my batteries. I went from ~14-16 min runtime on a 5000mah pack to 10 minutes.
