Our local Ace Hardware store is able to put it in a spray can, pressurized and ready to work like any other spray paint.

RE: do ailerons provide lift?

Trim the plane to fly straight and level.
Remove one aileron and fly again.

RE: do ailerons provide lift?

If you took a wing without ailerons, and cut a portion of the trailing edge to make an aileron, the wing would generate the same amount of lift.

RE: NEW DLE 20cc Gasser! (Data & Links 1st Post)

WWII planes had high horsepower and needed a lot of prop. Ground clearance was a problem. The Corsair went to a Gull Wing to help with ground clearance. Another issue is that a 9' diameter prop at...

Compare a spin to a vertical dive. The plane is stalled during a spin and the speed is much slower than durin a dive which is not stalled

RE: mAh vs volts

And the power needed to achieve those rpms will determine the current. In a car, the voltage will say how fast, going that speed uphill or down will dictate the current.
