Keith, you're gonna love this plane. I've had two, both had a .56 Saito. The .62 is the same physical size, except for a slightly fatter jug (cylinder). The extra power will certainly not be needed to fly it, but will make it a lot more fun.

This plane will fly at a walking pace, but will also haul butt. I had as much throw in my controls as the hinges would allow, and it was still easy to control. The wingspan controls how fast this plane will roll, you can time it on a calendar.

The elevator has a lot of authority, and it will loop tighter than you'd be willing to believe. The rudder also has a good bit of authority, and the model has a fair amount of pitch coupling when using only rudder, meaning that if you use just rudder, the nose will pitch down unless you counter with up elevator. There is not much dihedral, so aileron-only inputs don't get much turning action, just banking with some adverse yaw, but not quite like a Cub.

I'd recommend about 5/8 inch up and down throw on elevator, about 3/4 inch right-left on rudder; program in some differential on the ailerons, about 5/8 inch up and 3/8 inch down. (All this is low rate) for high rates, just give as much movement as the hinges allow, and I'd also mix about 25% rudder with ailerons for just flying around; put the mix on a switch so you can turn it off until you get used to the rudder.

Speaking of rudder....... check your gear to make sure you've got a little toe-in (equal) to help it track straight. As light as this plane is, and with the power of the .62, it's gonna want to swing left every time you hit the throttle on take-off, so you're gonna need to learn the rudder on this baby.

I don't know how thirsty the .62 is relative to the .56, but I was able to get 30 minute flights on the stock fuel tank with the .56. I never needed on-board glow, but a remote glow plug would be nice, it was a bit of a hassle getting to the glow plug for starting. I used a MA 12-6 prop for the .56, I think a 13-6 or 13-8 would work well with the .62, although the 13-8 might not let it slow down as well for landing. I had good, but not unlimited vertical, I'll bet you can hover (vertical) yours with the .62.

In a 15 mph breeze, I could keep mine in a horizontal hover and let it settle to the ground with a landing rollout of less than three feet.
This is one of the few "non-trainer" airplanes I think you could learn to fly on. It isn't quite as roll stable due to the low dihedral, but has a very slow stall speed. When it gets close to a stall, the wings will start wagging, and it usually would drop off on one wing, so keep it high for a while 'til you get used to it.

This is my take on how it flies, hope it helps you, good luck. Ken
