I aquired a Pica Junmeister already built. 59" wing span. Put incident meter on it and it looks straight. Weights about 9.5 lbs and has an old OS .90 FS installed. I've adjusted the control linkages and modified engine installation. The old engine runs ok but sure puts about a bunch of oil and mess. There is a lot of lead bolted to the motor mount, maybe a canadate for one of the small 15 or 17 cc gas engines? Anyone farmiliar with this plane. What is recommended cg, control throws, expo etc?? Balances 5" behind the leading edge of the top wing at the center section.

I cant remember where the CG is but it can handle a wide range and I fly mine a little tail heavy. Control throws; I have as much as I can get without binding anything, and I took all the expo out; the controls are slow; I also sealed the aileron gap. Mine is powered with a Mag .91 4 stroke, and flies it great but not overpowered. It is a scale plane not a 3Der, so it likes scale aerobatics.
