Balancing techniques?
I have balanced over the years many a two blade Zingers, APC etc. But I am endeavoring to build a scale P-38 within the year, and would love to install 3-Bladers with RCV engines.
Of course I would like to use three blade wood props and cut them down to round the edges, thus requiring balancing extraordinaire.
Any specific techniques in balancing 3-bladers that I should perhaps know about since I have never done it before?

Gotta love those P-38 rounded props with yellow tips....
"Ooooooooo........Aaaaaahhhhhhh!!!!!"

Hmmmm........
Lots of hits, but no real takers on this one.
No matter, I think I figured it out anyway.

P.S. Nothing but a referance to an old magazine issue? Doesn't do me much good since I don't subscribe....[X(]
Is that blasphemy?

RE: Balancing techniques?
Hmmm....In my limited experience of balancing 3 blade props, I find it not that much different from 2 blade props. If you think about it, the 'heavier' blade will weigh down the opposite 'lighter' blades, thus giving you a point to sand and balance. Sometimes you’ll get a ‘grandfather clock’ effect (back and forth), but that will give you a point of reference. Just remember, you’re sanding and trimming off the ‘heavier’ blade. I hope that helps.
Again, this is only from MY experience. Please trust your skills and judgment on balance!

RE: Balancing techniques?
Here's how I do it:
But seriously... Balancing a 3-blade prop is actually easier that a 2 blade.
One thing worth mentioning, number the blades so you can easily tell which one stopped where.
And remember, it's not overly critical. In other words: close is close enough.

RE: Balancing techniques?
You're right. I probably should not have bothered posting this thread. I got to thinking about it and sort devised my own method of doing it without taking forever. Probably isn't that big of a deal anyway.
