I just followed one of the links in the video thread. It was to a guy flying pattern on a sim. What I noticed is that he was flying through the maneuvers A LOT slower than I have been. I feel like this is better as it shows much more control of the aircraft. So what do you guys use for props? I'm going to my first competition next Saturday with a 40 size plane. I've been using an 11x5, but flying with lots of RPM and a little speed. I wasn't thrilled with a 12x5 as the engine (46AX) had a hard time with quick acceleration, but it did have plenty of pull and climb. Was thinking maybe a 12x4 so I could get more RPM's?

Thanks for your thoughts.

A well designed plane with a low wing loading allows this style of flight, making the pilot look better than he really is. A slower pattern can give you more time to correct. I like the way it makes the plane seem to be in more defiance of gravity, more effortless.
On a light enough plane, a 11x4 / .46 combo will work very well. The target weight / size would be 4.5 pounds and 600 square inches. Start out by adding up all the known weights of the onboard equipment and everything that is left over can go towards the airframe. This is what is fun about building your own model with a design objective in mind.

Try some 6" pitch props both 10 and 11 inch diameters. Listen carefully to your engine and make sure the 11*6 doesn't overload it.
Hopefully this article will help.

Good luck you will have fun with Jon at NEVRC. Wish I could make it.

Classic answer...it's the plane, not the pilot

Hey!
Where can I get one of them planes that makes "the pilot look better than he really is"?
I need one REALLY, REALLY bad![sm=bananahead.gif]

John,
You can get one of those "magical" (pun intended) airplanes right here: http://www.customairframes.com
Some assembly required. LOL
