Hi Guys,
Someone Asked me many weeks ago how did i balance edf unit as i mentioned i had to do it for my 12 blade Edf.

I am Sorry for not Uploading this Sooner and i Know That it may be Useful to Some.

A BALANCED EDF CAN REDUCE THE OUTPUT VIBRATION NOISE BY AN AMAZING AMOUNT AND SOUND BETTER AND QUIETER

You can Actually notice on my Stryker 90mm edf view Clip that there is still some slight Vibration during Flight but minimal.
I probably will Rebalance it again and see if i cannot get Rid of it Totally but it was Absolutely Terrible when i first put it Together and did a power Test at Home.
I actually got mine in in pieces and had to slot in each blade in and while doing that i balance it out as well.
Using a simple method of rearranging the blades till i got it balanced and did not have to add any weight at all.

I just balanced out my 10 blade edf last night and took a snap shot of it in practice.

Items Required -
1 Prop Balancer
Blue Tack
White Marking Pen
And some Epoxy or Silastic for the Permanent Weight.

I use Blue Tack for my Temporary Weight and once Done replace it with Epoxy and then if needed once Dry i cut away a bit of Epoxy or add a touch more.

And Lots of Patience

   

Bleow is the Actual amount of blue Tack that was Required to Balnce it Out that i Replaced with Epoxy.
   


Finished Product with Epoxy set and you can see it was slightly scaped out a bit to get spot on, Epoxy opposite mark, as the mark was the Heaviest point.
It spins and stops in any position Now, BALANCED Yeh !
   

Here is a Video Clip That I found on the You Tube That explains it quite well and basically is the Same way as i do it, so no need it upload one.

Remember the edf Prop Shaft is important to be balanced as well but you will know this when you see the distance of blades to the outer Rim of Edf and adjust either prop adaptor or motor position to suit, dont just cut the Blades or then you will have an im balanced edf prop and back to Square one.

Just finished balancing my 90mm 12 Blade Edf, added a bit of Epoxy weight to correct.
Hers Hoping for a lot Smoother Sound as a Static Test i just did sounds really Good with No Vibration at All., not that i can notice, a Vid cam Flight test will spot it if any.
