Too Much Power on FT Flyer?

#1
I think I made a mistake by getting a 1400KV motor, and then I also bought a 3s 2200mah for the FT flyer.

I know its going to be a bit rough, but how will this all work out? Can I just go at a small bit of throttle to fly slowly around a big park with a baseball field, or will this thing be too heavy and too fast. I don't want to switch out the motor, but I tried "calculating" the flight time and it seemed that with a 1000mah battery it'd only last 2 minutes.

Need some advice.

How big is the motor? we can't guess the size of the motor and give an opinion, the lipo seems a little heavy for the plane.

that motor is meant to run on a slow prop your battery is a bit to heavy. maybe not just make sure you put a slow fly prop. warning that plane is a prop killer. i used to use a prop saver on that plane.

What's a slow fly prop?
A slow-fly prop has wider blades and a heavily cambered airfoil to give a lot of thrust for slow-flying models.
Compare the first picture, an 8x6 prop from APC with the second picture, an 8x6 slow-fly prop also from APC.

I see. My prop looks like a slowfly prop:

but it also has two different ones, a tractor and a pusher.

Ah, I see. Your prop isn’t a slow-fly prop it’s just an APC style prop. The slow-fly has really thin blades near the hub and wide, rounded blades near the tip.
Your props have nice, sturdy blades near the hub that flare out and then thin back down towards the tips. It’s more efficient for use with electric motors on lower drag airplanes. It should still work okay for an FT Flyer

Alright. Could you recommend some cheap slow props?
