Default Wjhat is a reasonable flying speed for sport aerobatics.

What is considered a reasonable flying speed to aim at obtaining for a gas powered 68" span 10 lb. Extra with a 27 oz./sq.ft. wing loading, being used for easy general sport flying and basic aerobatics, no hot dogging stuff.

No fixed number works. The speed at which the plane will safely and effectively fly most maneuvers equally on an up and down line. Level, up, and down, all generally equal. That's usually a lot slower than most fly at, including myself.

Sufer is correct the speed on the up and down lines should be the same as the horzontal speed. This means that you MUST use the throttle as something other than an on/off switch

Hey silversurfer, my plane flies vertical as fast as it does level you know that
tkg and silversurfer are correct though. But if you are looking for a mph number, I would guess a range of 30-70 for general sport aerobatics. If you 3D that could also go to 0 mph, but you are not really flying then.

I am planning to prop my engine to achieve a top speed of about 55 mph.

DO NOT prop your motor to achieve the top speed you desire!!! You want the motor propped to be in the manufacturers recommended rpm range. You may get lucky doing what you want to do....but chances are, depending on the motor, you'll end up having it under propped and spinning to many rpm's on the top end.....or it will wind up over propped and the motor will always be too loaded......neither of which is good. You're best bet, in my opininion, is to prop it correctly within specs, and use you're ATV's on you're throttle servo to limit the motor to fly at the speed you want when max stick is given. This way the motor is happy...and so are you. Personally, I just think it's an even better practice to not worry about it, and just use good old fashioned throttle management when flying.

Cap,

That makes a whole lot of sense. Hopefully I will get lucky.
