Dear Ray, How rude can I get? I forgot to tell you how the Oly2sx build came out. This was finished in late September, after I harassed you to send me some missing parts!
I did use the suggested pushrod-operated spoiler system, which works very well.
The plane hasn't had a lot of airtime yet, having been out to the SKSS field only 4 times and sadly on days with minimal lift. Most launches were from a histart but it also had 3 launches on an ESL-type winch, with no control or structural problems at all. Best time so far is 12 minutes.
Launches and landings are very easy and smooth and it "wants" to thermal but so far has had little opportunity.
The only surprising thing I noticed was that rudder authority at low speeds seems weak. I have to hold rudder on longer than expected to get response sometimes. I wonder if the original Oly aero-balanced rudder would make it snappier. The old Oly and the Sagitta were very responsive to rudder. ..or else I could have built in more polyhedral. But this is a quibble - it doesn't affect normal maneuvering or thermal turns.
I didn't try to make the '2SX very slick, just kept it simple and as per plan, and I think it's come out very well. I'm pleased that it's at home on both histart and an aggressive winch and it has a better distance range than the old Oly.
Finished my olly 3 and took it for its maiden flight, stayed up 40 minutes and second flight 57 minutes, could not believe the height it got , you could fit it onto a postage stamp, loved the build and i am rather new at thermal flying but laid back on the deck chair and could not believe the lift l keep getting, on the second flight l was glad when it came down, thinking of ordering a Windfree for next build, is this plane also a good thermal glider, hope you like the pictures

Gene is building a polyhedral wing version and hopefully he will send us a
photo when it is completed.

I did put 3/8" x .007 CF inside the four aft fuselage sides and also in the inner wing panel trailing edges. It's covered with Ultracoat lightweight white with Ultra-coat transparent violet on the bottom of the wing and stab (it looks great with the sun behind it). I also built a small compartment over the C.G. for two 3 oz bags of shot.
As soon as it was done I headed to a local
yard for some hand launches and as expected, it floated around very nicely
without ballast. Today I was at our club field for some winch launches and
I did use 3 oz of ballast. I was amazed how high the Bird got
on launch and how well it penetrates. I think I'll just leave the
ballast in it unless it's a no wind day, but more flying will sort that
out . It's pretty much a "no brainer" finding lift because
the plane really tell you when it's in even the lightest lift.
Mark Garvey sent this photo of his 2M Lil Bird and in his letter said,
"I absolutely love this model. It is difficult for me to go into it without going for huge exaggerations, but it is simply an excellent model to build and fly. Building is simple due to laser cut parts, and once built, it is an absolute delight to fly"
