Thanks in advance,

I have built 3 of them. First one was per instructions. Long span swept back wings. I hated the scarf joints. Second one I built I did the fuse per plane but cut foam cores for the wings. Third one was a scratch built with foam core wings and a fuse that used lots of lighter weight balsa.

I powered them with a K&B .65, ASp .61, ST.61, O.S. 70fs, Saito 1.20fs. The 120 was to heavy but had loads of veritcal. The 70 was to wimpy but flew like a PT-17 trainer. The .61's worked pretty good. With the .752c or a good 90fs engines out there I think that they would be a good choice.

All of them flew very well. They can float in or tear up the sky. I liked it when I had some big ole ballon tires on it. It looked like a bush plane. When you do build it go with a servo for each ali and go with 1 ali on each wing. It would do some crazy snap rolls.

I have one with a Super Tigre S61K, turning a 13x8 Master Airscrew. It flies very well, but don't expect it to fly pattern-style ( i.e. not really "go where you point it").

Mine is with the short span wing and straight lower wing.

Glide on landing approach is better than you can normally expect from a biplane.

Same recommendation : use one servo per aileron. If I could do this again, I would also put ailerons in the top wing. The roll rate as it is, is not very high, not even with a lot of aileron deflection. This is not a Pitts or an Ultimate! Also, I did not think that knife edge performance was as great as advertised : pitch and yaw coupling with rudder input, so that's a little bit tricky. My CG is at the most rearward position, so that should not be too bad for knife edge.

A great looking airplane, realistic flight, easy transport because of compact dimensions for a 60 size plane.

I'll post a pic if I find a digitized one. I am just in love with the looks of this plane.

Thanks for the pics Kris. Can't help notice the lack of outer wing braces. Is this typical ??

Thanks,
Bob

Bob,

According to the plan/kit, outer wing braces are optional ( i.e. cosmetic).The wing is sufficiently stiff ro fly without them, and if I can avoid additional weight and/or complexity, I can't help but do it .

I once flew a Hal DeBolt Acrobat that needed them : when I rolled, the wingtip of the top wing touched the one of the bottom wing Top wing was held in place with a lot of rubber bands, bottom one with nylon bolts.

best regards,

Kris
