Sorta Sterling BRM

Post  944_Jim on Sun Apr 22, 2018 2:49 pm

Hi All,

Please help with a decision. I have been working on a BRM from tracings I found on OZ and HPA.

Now that I'm close to final assembly, I wanted hard numbers on bellcrank assembly and engine mount details.

Today I found a copy of Pat King's BRM clone. I hope he chose to up-size the wing...or I blew printing the original patterns. His root chord is five inches, while mine is four inches.

This kit is going to a boy at church...so it really needs to be able to stay in the air, and land with durability in mind.

What is the root chord on the original BRM?
Should I make a new wing?

Thanks in advance for any help you can provide...I'm all ears (well, eyes).

Big THANKS to Chancey.

It turns out I cut my wood based on his BRM templates. I lost the ones I used for patterns. He generously supplied his copies, and they confirm that I'm on the right track with this bird.
Completed pics with new owner will follow soon!
