castle datalog rpm off?

[nick779]

i was looking at my castle logs today after a flight, and my gov settings on my 450 pro are 2600, 2800 and 3000rpm, now when looking at my castle logs it was saying my max headspeed was 2200rpm..... and i really doubt the heli would even hover at that rpm without almost being full stick... and i had plenty of collective pop...

anyone else ever have this issue? its only the 450s 2nd flight and today it was 45 degrees out...

its first flight (36 degrees out) the castle log was perfect and id think if it was a binding issue, i would have seen it on the colder day, but now its messed up...

Two ways to go.
Use a tach (have someone else tach your model while flying)
or check your gear ratio in Castlelink. If your gear ratio, motor poles, motor kv are all correct in
Castlelink, the RPM show there is correct.

well the ratio shown in the log is wrong, but its right in the esc setup, but i think it was like that last time too...

ill have to try to replicate it again and use my tach app and see whats up

Redownload the settings from the ESC, make sure the gear ratio is correct, then resend to ESC. If it is not right in the log, it can't be right in the ESC, unless it got changed somewhere.

You have to set the motor pole and kV values in the software used to view the logs. I have no idea why this info isn't transferred over from the ESC, but it isn't.
