DeHavilland Beaver CG?
by: Anonymous

G'day Which one, I found several with a quick Google search. Most planes with straight wings like the Beaver balance at about 1/3 of the chord of the wing and this is usually close to the main spar.

If you can't find any info, I would go with the front of the spar or even a little forward of it. Too nose heavy is better than too tail heavy for a test flight. Tail heavy and it will be unstable, nose heavy and it will be docile and unresponsive but controllable.

G'day

Glad your model flew well. Sounds like quite a large Beaver if you have an OS 120 in it.

I was doing some test flying today too. I was testing a second hand Enya 40SS which I bought from a certain auction site in a Sig Kadet LT-40. I had flown the Kadet before with a Saito 56 four stroke but that engine is now in another plane and when the Enya turned up cheap I decided to give it a go. It went really well. The previous owner had the air bleed carby set for maximum rich running which was just too rich but it is now working really well.

Have fun. That is what this is all about.
