Sounds like a viable plan. Go for it and report your experience.
John,
After soldering the connectors and charging up the battery, I ran the motor on the bench for the first
time using my exotic 30A Hobby King Blue ESC (11.95) and a 9- APC electric prop. After transmitter
calibration, it would rev up to about 5800 RPM and sag back to 3000 in a hurry. The HK ESC is the same
as a Turnigy ESC.
I then tried an 8-4 nitro prop and got the same result.
I would imagine I'd never see the max RPM (980*6.53 = 6399), but I wasn't happy with only half the
speed, thinking something was going to overheat. After poking thru the manual, I managed to change the
controller over to NiCad battery mode and it held the 5800 RPM with either prop. Most probably it was responding
to the low voltage condition of a 2s LiPo.
This seems to be adequate thrust to fly a Griffin, which was designed for .09 - .15 engines. So far, I have $16.95
in the project, since the battery is a 1700 mah LiFe4 from an ACE biplane.
Maybe I should make a tach disc for bench testing the controller to find what the max RPM is. Has anyone
done that ?
