Your numbers will be off if you are testing the motor/prop in a static bench test. When the plane is in the air the air is passing into the prop as fast as the plane is traveling +/- wind. The...

the 7x9 prop is boss on this plane for speed, BUT you might be set with the 8x5 prop for over all fun, your plane is faster then anyone's PKZSpit that you are ever likely to run into.

The surface area that is removed is a rather small % of the wing lift area, BUT when you go to roll it is much faster. Even if you mod the wing and somehow it just doesnt seem right, the wing is...

Dont listen to that propaganda, the fact is the faster you are moving the less travel you will need with your ailerons, the key is to make slow wide turns and you will be just fine.

It all depends on what prop size you use, that motor will produce enough thrust to get you plane off the ground if you use the right prop.

The larger the diameter the prop is the slower the plane...

I am not so much worried about the Kv more then i am concerned with the match up of the prop. That motor will do a fine job flying this plane, but i do agree that the 1400Kv motor IMO i a good...

What concerns me is the Kv rating on the motor 1700kv IMO won't go very well with the 8x8 prop. My prediction is with a static bench test you will be over the 40 amps (or atleast very close), but...

Direct drive is the way to go, 80mph is no joke, the plane really needs to have a lot of power to do 80. Your 40A ESC should be enough, if you read thru the later pages you will find different...

It is true you built drag from the plane at higher speeds, but your motor has to work harder to suck the air into the prop when you do a bench test. I have found that using a high speed fan to force...

The amount of drag the supercub has compaired to the spitfire it huge.

Keep in mind also static bench testing will not give accurate results on amp draw either.
