hotter......
What head speed are you running?2320
What timing are you using in the ESC?
the PWM setting can be really important in matching it all up. (just learning about all this now)
you should run governor mode to get stable headspeed ... especially if you are getting into 3d
80% flat governed throttle curve.
just ... speeling what I have learned in the last 24 hours....
I am not sure how to set up the Castle..... but I have learned that hot motors are sometimes PWM rate not set up correctly from the research I have been doing anyway.
I heard that Scorpions like 5-8 Khz depending on the ESC.....
from what I have been researching for my new ESC (YGE CLONE ON ITS WAY) Pwm is really important as if you have it too high ... you get lots of heat ... and too low ... they run cool but are inefficient (the Motors)
the calcs I have been looking at say
POLE COUNT (P) x KV (K) x VOLTAGE (V) /(DIVIDED BY) 20
so for eg: my motor BL650L (ALIGN - OLD BUT HEY IT IS WHAT IS IS LOL)
P = 6
KV = 1220
V = 25.2 (6s)
6 x 1220 x 25.2 = 184,464
/ 20 = 9,223.2 Hz
= 9Khz (round down and test) .... cooler option first. Most ESC's with adjustable PWM setup will b 8Khz by default (as far as I have read) Castle may be 5? not sure.
