Default Fast, Small, Cheap

Although not extremely fast in terms of miles per hour. There is no question flying my 1/12 scale Pica P51 is fast. I replace the original OS FP 20 with a Novell .25 turning a 7" prop and the speed difference was amazing.

It's small size 34" span and 110+ mph speeds make it seem faster to fly than my diamond dust. Even though the true speed is not as fast. It gets very small in a hurry, and definatlly fills the need for speed.

An inexpensive easy to build kit, and inexpensive reliable motor, and a inexpensive 3 channel Focus 3 radio and for under $200 you have something that's fast and will keep you on your toes.

To get it to launch with the small prop I pretty much have to use a catapult. But it really picks up speed, going to a 9-4 prop makes hand launching easy, and it still looks fast but isn't like using the 8-6 or 7-7 prop.

Is anybody else going fast with small planes.

Tom

How about that Corsair in the background? What engine? Is it fast?

The Corsair in the background is a Pica ART (scratch and dent) with an old beat up ASP .32 It weighs about 3 pounds and is very stable for a small warbird. It is considerably larger than the mustang but also appears to fly very fast, My best guess of it's actual speed is about 100 mph, (avg lap times compared to the mustang and my diamond dust and math estimates based on 8-6 prop) There is room for some more speed in the corsair but the big round frontal area limits it. It is very easy to fly. The cleaner airframe of the mustang and wing shape make it a faster plane.

The catapult works great and is from a kit by WarBirds Ltd. www.warbirdsltd.com Don't use this catapult with a foam plane as it will tear it appart. even without engine running it provides enough power to fly the little mustang or corsair a good 75 to 100 feet. My takeoffs using the catapult are at about 1/2 throttle to reduce the torque of the engine twisting the plane during launch and I then power up after it starts flying.


One thing I've noticed is that a small warbird going 100 mph looks much faster than a big IMAC going 125+ mph.

Speed and size are relative.
