Default eFlite Adagio 280

Adagio 280 from eFlite - anyone have time with this little sailplane?
I picked one up from a club member. Some of the old reviews weren't too favorable but sounded like more experienced flyers were happy with it.

I flew it...briefly. About 3/4 of the pattern and got a nasty loss of control about 50' as I was approaching the runway to land. Plunged nose first into a dirt nap. Not sure why, but there were some questionable conditions of wing surfaces where it had been suspended by the previous owner and I think a CF rod may not have been seated properly on the wing underside. She was very unstable. A post flight showed really no structure damage that could not be repaired or straightened so I got busy. Boiling water fixed the nose droop. An aluminum rod insert fixed the CF main spar. Smaller underside spars were gently lifted and re-glued - they were really weak on the glue and nil adhesion in several key points which reflected some of the flexing I saw during the brief flight. I think the motor may be ok, but what the heck they are small and cheap so new on the way. Steam got the twists and tweaks removed, and dents in the wing removed. She gets new paint and a polycryllic treatment to stiffen her up a bit more and we'll try again. She also got some 3/16 Balsa strategically around the fuselage and spar interconnect at wing root.
Judging by some reviews it was a huge disappointment for Horizon and owners and for apparently no other reason than folding wings and weak glue. The structure is also quite fragile for a park flyer.
I think it had potential so I will give it another chance - such a classy looking bird

And so I did.
New motor and ESC from the P-38. Removed and reglued the lower wing CF rods.
1/8th balsa spar box in the fuselage.
Needed a new main CF spar but I spliced it with an aluminum tube and epoxy.
4 coats of Polycryllic made it a lot less flimsy.
No change in CG and weight only went up .68 oz.

Took 3 flights to get all the adjustments right, but she is a fun airplane. Totally cool slow aerobatics, flies fast when you want, grabs a thermal without a big pitch up, and no mix was needed for the flaps either. Even the first 2 flights she made good landings look easy.
I needed spotter and trim assist on first 2 flights as she would not allow me to let go of a stick long enough to throw in trim. 5 turns on the up elevator clevis after the first flight. Shortened the left aileron push rod after 2nd flight.
What a glider!
If you can find one - get it! She’ll need some luv to get rid of all the flimsy, but what a blast!
