I too received a Seawind for my Birthday last week. I must say it is beautiful. I always admired the full scale bird. I have a 3.5 acre pond to fly off with hills surrounding so I need some takeoff power. Mine will have a YS .91 swinging a Bolly 12.5X11 three blade and lots of nitro. I will upgrade the rudder and elevator servos to Hitec 5245 mini digitals.
My main concern about the kit is the balance procedure. GP states that it should be balanced with an empty fuel tank; but the tank is behind the CG so when you fill the tank you will be adding 10 to 12 ounces of weight behind the CG. I will be placing my tank in the hull right on the CG so I will avoid the full tank/empty tank balance changes. Did GP allow for the weight of fuel when calculating the recommended CG using the tank they supplied? If so do I need to change the CG to allow for my situation with the tank right on the CG down in the hull? Anyone with info on this? Thanks,
