Prop balancing

[Kevin Rochon]

I was explaining to Michel tonight how I balanced my props so here is the video I thought it might be useful for others too.

Thanks, Kevin. I always balanced the tips but never knew about balancing the hub until you told me a few weeks ago. The video explains it well.

He uses tape for the hub others use velcro and add crazy glue to the velco until is balanced.

The way he does it of course is for a speedy way to demonstrate.

When I balance a WOOD prop the first step is of course to get it to balance level, ie horizontally, for that I use a can of spray varnish to the lighter end with light coats until it balances, in between I use my heat gun to accelerate the drying. Once that is done the next day(so to be sure everything is dry) I retest the level bal. and adjust if necessary.

Now for the hub I drill a hole on the lighter side and insert small pieces of solder(lead). Where to drill, I test first with some tape just to see to proper position.

For plastic prop I usually scrape with an Xacto, and fo small electric I use Scothtape if it's worth it.

After all that remember that it never stays perfect for long the first time you taxi through the grass it starts getting off bal.;)

P.S. I find it funny when the manufacturer of the prop mentions "Hand Balance" ya right:rolleyes:
