Some will argue it is the same but not to me. I found statically balancing a rotor pointless because the whole unit which is rotor, spinner, collet, and motor all spin together and all contribute to the out of balance condition. Balancing only one items does no good. The hyperflow fan is a perfect example, the spinner is molded out of round. The fan can be balanced but adding the spinner makes it then go out of balance. So it makes more sense to spin it all assembled together which you can not do on a static balancer.

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

But can't you assemble the rotor with cone and adapter put together as one unit on the magnetic prop balancers, just use a marking pin to align things up the way they were positiond on the balancer. The only thing you cannot balance is the small screw that holds the cone on.

I guess the only fans you can not balance are fans that do not have a hole centered in cone?

I have found trying to do all that was much more difficult in reality. For me the machine was worth every penny spent, and it saved me messing around for long periods with a mag balancer and still I typically had them balance on the mag balancer yet still shook when spun up so it was frustrating before and it is no longer. The main thing is it tells you where the weight needs to go so you just add or subtract weight which makes it go much quicker.

Is the balance service limited to your products? Could you handle motor/fan assemblies purchased elsewhere? I was thinking if we provide the box and postage both ways??? Also maybe with a caveat that if the unit is just too screwed to balance we still have to pay.

I have done a few for a few people, what do you have in mind? I did not want to turn into a balancing service for everyone as it can take a while to get one to balance and was intended to be more an extended service for those who are buying a motor and fan unit. But shoot me a PM or email as to wht you want balanced.

I kind of figured. Seems like a lot of work for $12.50. That's cool.

So how do you balance the rotor? I see you use the timing light mechanism... But I do not see how you balance the rotor?

See the last photo in post #1 it shows the white weight inside the rotor spinner.

Since a lot of the time the hub or collet is out of balance as described earlier, do you have to mark the fan and adapter or collet every time you add weight and take it off? Seems if you did not put it on exactly every time you took it off it would continue to be out of balalnce. Took about 45 mins to get my rotor to balance perfect on a magnetic prop balancer, I had to mark adapter and various parts to align perfectly when I installed on motor. Would of take that much time I just did not have proper material to use for balanceing.. It made a huge difference, this was the first time I ever installed a HET rotor that did not rub. from the 4 wemotoc 480 rotors I have purchased all have been perfect out ofthe box with no rubbing. all the rc landers need balancing, Have not tried the wm400 yet.

Yes they are marked so the positions can be replicated.

Just placed my order for a new motor, fan and of course balancing service. Look forward to seeing your hard work in action in my F-18.

Cheers
