RE: Alpha Corsair vs 3d Flyer
Groby,
Steer clear of any of the Alfa's UNTIL you have a fair bit of 4 channel experience.
They fly at similar speeds to .46 glow powered, low wing sports models 3 times their size, even with the stock Speed 300 and 5:1 gearbox.
Also, the recomended control settings that Alfa give in their instructions are way over the top and unless you have had experience in controlling over sensetive and out of trim models, you will be flying a "crash waiting to happen," until you can get the settings adjusted to where you want them.
Transition up to an Alfa via something easier.
Good luck.
