My Speedster with a Turnigy 2730 1200kv, 8x4.5 slowfly prop, and 1300mah battery leaps off the ground with about 1 foot of takeoff roll so I imagine it would lift a 2200 OK. Lighter will always fly better though...

I just built and maiden flied my Old Speedster.
Just love the looks of the plane.
In maiden she pitched up constantly and i needed to use down elevator to fly straight.
I have now added bit down thrust on motor to counteract that.

On second flite it just collapsed wings in mid flite. I bet it is because my foam does not have papercover.
So i added then spar under the wing to strengthen it.

Here is video of the maidenflight.

After trimming it flies great. Slow and low. :)
