Basically you spin the rotor up at a low rpm, about 1/4 throttle and you first find the heavy spot and record its location. You then intentionally add weight to a know location to find the "phase shift". Once you find these positions you then know where to add the weight to get the rotor to balance. You then add or subtract weight as needed to get it to balance correctly.

Don, what are you using as weight inside the fan housing? I can't quite tell from the pics.

Yes, another inquiring mind wants to know as well.

BTW, I finished up my Exceed RC FA18 with your BI 3600, 80 amp Pentium and Het fan. It should make it a pretty good flyer. I hope it doesn't rip the wings off .

You do have the advantage of being able to fly in the winter, but I can fly until 10 PM at night during the long days of summer and not die of heat stroke.

True

But you get used to it though, just drink plenty of fluids!

Yes RPMs go up and amps do drop a little it really depends on how out of balance they are to start with but if you need a few things balanced let me know.

I can vouch for Don's mad skillz! I ordered 2 of the 60mm fans w/ 4400+ motors w/ balancing and they are spot on! Better than I could do.

I throttled them up and not even a single scratch from blades rubbing. They sounded awesome. Great work Don!

Will a prop balance on high earth magnets work as well?
