RE: Goldwing Su-26m Build
Hi All,
Today I went to the club where the person (who owns the website from which I bought the Su26) regularly fly. It was a perfect day, and could enjoy 4 flights of almost 20 min each. Ihad not flown that much ever before. All flights went uneventful. unfortunately did not land any time, I couldn't get familiar with two things: this plane floats a lot, the landing strip is almost half the length of the one I have been flying over a year. Is this common?
Well the Su26m and the engine combination to deliver a really fun plane to fly. Although my flight style is rather conservative, the plane behaves quite stable and allows way more than I intend to do.
Some lessons I can share:
flight behavior: knife flight: really easy and stable. The plane really floates, though it demands speed on landing approach.
wing balancing: very important. I had to add over 50g on the right wingtip to compensate from a notorious excess of weight of left wing.
nose heavy: after reading a lot of tail heavy natural weight distruibution on the Su26, I found myself adding weight to the tail; almost 20g which I think it'sa lot and it's still nose heavy. Keep in mind the chrome spinner had to wait to next balance evaluation.
CG indicated on the booklet: totally discarded, it drives too much weight on the nose. I removed the weights I attached on the nose when balanced the plane.
This isa common observation: bolts get loose, check before flight. I lost one of the bolts on the cowling and almost a second bolt holding the canopy. Exhaust got loose, and I still have to review the remaining elements. Forgot to mention that the fuel cap got lost on one of the flights...
I totally enjoy the engine, It seems to operate as one fine piece of engineering.
Well, here some pics to share,
