How To Balance A 2-Blade Propeller | Quick Tip | Motion RC 

hahaha. whatever works!

Good point Vic! I will now confidently balance props I haven’t known how to before.

Hey Dave, unfortunately, I will not be able to attend Wesley's show now.

Hey Darko 👊🏻

Hey GB 😊👊

Ty4sharing!!

Finally someone got it ;)

you can try to bend it back with a vice, is this our Benchcraft prop balancer? If so, contact customer service

Yes this is a bench craft from motion rc

I wiped off the excess as I sanded yes.

Same method. Keep changing positions to see which one drops the fastest. The heavier one of course will be on the bottom.

@@victorrcjets7660 did not think of that Victor. I will have to give it a go, need a taller rig. 👍🏻

My process on three blade props, which I mainly use. Usually Master Airscrew glass filled nylon, but works on plastic or wood as well. Install prop on balancer. One blade will be towards bottom, every time. Two blades will be high and on each side of vertical center. One of the top two blades (which are the two light blades) will be hanging lower than the other. Lightly use sandpaper evenly down the entire length of the lower blade (it is the heavier of the two lighter blades), sand until the heaviest blade (the one actually pointing down, not the one you are sanding) hangs in the completely vertical piston pointing down. At this point the two light blades are the balanced leaving the remaining heaviest blade pointing straight down. Now apply the sandpaper to the heavy blade until prop stays where you put everytime with no blade swinging to the bottom. At this point all three blades are balanced. I know some people use tape, but tape can come off in mid flight. This can lead to instant severe vibrations that at high rpm can shatter a planes structure violently. By sanding this is prevented as no material removed by sandpaper can magically reappear later. May be other ways, but that is how I do them. Can make a video and post on my RU-vid chsnnel if it would help, when i get home this afternoon. Maybe, I only have my phone camera.

? The prop wasn't on it?

@@MotionRC Yes. When you spun the balancer with no prop on it the balancer itself looked out of balance. Gotta balance the balancer ; )

@@NETBotic it just wasn't seated properly, and didn't need to be without the prop on it
