Default RE: Balancing tailerons?

Yep, it's a Flanker, 9' OAL. Bertelli plans, much modified (for example, he drew fixed stabs and elevators). Being on the poor side, I've got 2 'low mileage' JPX 260P's, trying to shoehorn everything into the fuse is a challenge. The propane tanks just do fit into the intakes. I am looking at the new Jet Joe turbines with interest. Scratch building the gear due to the wierd geometry of the mains. I've got a Japanese made video of the Su 27 that's got some of the best photography I've ever seen (called Ram-K)which allows one to see all the control surface movements. Getting ready to cut in the LE flaps, as soon as I work up the courage-fearing making a mistake! The tailerons will use 1/4" shafts in 1/4 X 5/8 bearings mounted in AC ply bearing blocks. Probably two servos each side.
Wow! A big'un. Poor being a relative term, right?

I make and sell a little twin EDF wood Flanker kit, so I know what you mean about the limited amount of space inside. I'd imagine the GRP models have a bit more room thanks to the reduction in internal structures. Even so, there's not that much room inside. The Flanker is actually a pretty trim design with no excess bumps or bulges.

I'm keeping my eye on JJ, too. I ordered the Flankers CD from Russia and it has video on it that sounds similar. It even shows the inlet screens moving up and down.

When you say 1/4"shafts, I assume you mean 1/4" steel shafts, correct? I wouldn't trust a model of that size to a flimsy 1/4" aluminum shaft.

You might think about posting a thread on the Jet forum. I'm sure everyone would like to follow your progress like they have with Harald's Flanker.
