Hi Chuck, no I haven't got to fly his big one, he is in NY and not flying anything right now without skis. He says it flys just like the 60 size though. When I was still in CA. I had both the 40 and 60 and used to use it as A second plane for students until I discovered the 4* was an easier plane to build and fly, build anyway. The only negative is the wire LG, it works OK but it's just so ugly!! Caster, you still sleeping on that kit?? Been over A year sense you got it. You understand what a termite can do to balsa.
Fact, you don't need big high powered servos on something like the giant SS, it's not A huge 3-D plane. Just get the best servos you can afford because they will be with you for years. Hitec 625 635 645 would work fine in this plane if you want analog. The 5475s are A pretty good digital servo for the price too. Bigger servos could be better but don't go too nuts on them unless you are looking for future use. Gas engines don't all need to be high dollar or cheap Chineese come over the pond engine, take A look at the Zenoahs, very user friendly, you don't need A DA to be happy. It would be nice but not needed.
