Slope Sailplanes

[kimbuehre]

Hey Guys,

Tis the building season. Time to get ready for spring slope soaring! Gotta have a foamy for Blueberry hill because the flying is rough.

Check out these websites for EPP foam sloper. "leadingedgegliders.com" has several foam warbirds and a low priced ($50) flying wing called the prairie dog combat wing. I bought the 60" leg one slope racer and need to build it.

You could also check out "magnumrcproducts.com". Check out the video on the "element". At "skykingrcproducts.com" they have re-kitted some older discontinued, but good, EPP foam planes. Check out the Daves Aircraft works designs. I got my first foamy from them. They have a nice looking 1-26. Also check out the Whirlwind Designed by Brian Courtice. This looks like a good slope trainer. Check out the Whirlwind video.

But hey, if you are going to fly the slope, you've got to have a wing. If we all have one, doing combat flying is a hoot. The more the better. Hit your opponent out of the air, do a victory roll and you are the winner. Check out the original at "Zagi.com" They are also about $50 for a kit and it looks like they have made some improvements in the design. Maybe I'll get a new Zagi. They are "nearly indestructable", but they do get mushed up after awhile. I am on my second one. Evan still has the original Zagi flying - it is almost reaching "classic aircraft" status.

Nuf for now. Lets get a large group of slopers this spring!

WOW!!!!!!!!!!!!

These are slope soarers??? Dang, sign me up. I like this one a LOT. It looks like a P40 Warbird, but it is actually a GLIDER. Incredible!

I wonder why they aren't motorized. Doesn't it look like it would be incredibly easy to put a motor in one? I don't think you could do a folding prop because of the nose design. But this would be an incredible powered glider capable of the slopes.

Wow, thanks Kim!!!

And as far as Zaggy's, whaddya think of the GO-229 in these shots? How's that for a wing? Only $90 bucks too!

I love slope soaring most of all the styles of rc flying. They sure can get going fast...

[bearcat]

I like that music too!

Okay, I wrote in and got the following e-mail response (read bottom to top).
So people do power these, but takes a larger motor. Interesting. A slope soarer that can double as a powered plane:


They can and have been but they have slope airfoils so you must overpower them to get them to go. The stall speeds are high also because the foils dont produce much lift.

The guy said:

"They can and have been [putting motors on them] but they have slope airfoils so you must overpower them to get them to go."

What does that mean?

I like this one with no motor.

Note: If you have wind on a slope, you almost can't crash, and can stay up for freakin' ever...

Mitch, I think that what he means is that the wings are designed not to produce much lift so that they can penetrate strong winds better. So you have to have enough power to fly them fast so that the wing can produce enough lift.

You know what? That means they are much closer to a real warbird. The P-51 had an airfoil that was built for speed, not max lift. Most RC versions have the airfoil altered to improve lift.

And I know a way to possibly MAKE the wing lift better for take-off and landing. Why not just have the ailerons double as flaps by using a mixer? You put down full flaps and the wing will create more lift and slow the plane down. It's worth a try.

Sure, these are meant as slope soarers. But why can't they double as a conventional powered airplane? They would be very fast with the flaps up. Interesting idea. You can still slope soar them without the prop too. I'd just leave the motor in it and remove the prop.
