Too Windy to fly your airplane? - Try This!

You are itching to fly your foamy, whether it is an Easy Star, an Easy Glider, a Supr Cub, an F27 Stryker, T-28 or some other form of flying beer cooler. You love how they fly, how the look and how they stand up to rough landings.

Your flying day is coming up and you look at the weather report and there it is ... the wind forecast ... too windy for flying your foamy. How depressing!


Well maybe not!


Have you ever heard of slope soaring?


Slope soaring is a flying techniques that LOVES wind. And slope soaring can give you super long flights on one battery because you can leave the motor off most of the time. Most people associate slope soaring with gliders but most electric airplanes can be used for slope soaring too, especially the foamies.


I have gone slope soaring with Aerobirds, Easy Stars, Easy Gliders, Super Cubs, Radian's and other foamies. Slope soaring was my joy when the wind came up and it was too windy to fly at the flying field. I actually started to look for windy days so I could go slope soaring.



Here is how slope soaring works.

Click on the link to see a great diagram of how slope soaring works.

http://users.iafrica.com/s/st/stevemac/afc/ssoar.html


As wind hits a hill it has to turn to go up over the hill. This creates a pressure zone, a lift zone that your foamy can ride. Think of this as model airplane surfing. Riding the curl for as long as you like.

If 10 mph sounds like too much wind at your flying field, you may find it is right were excellent slope soaring begins. Now you need a hill.

The taller the hill, the higher the wind speed, the greater the lift and the larger and heavier the aircraft you can fly. The clearer it is in front of the hill the smoother the air will be. Buildings create bumps, like rocks in a stream. Ocean and lake shores are wonderful slope sites. Mountain areas and high ridges that have open space in front of them are fantastic. Dams can be fantastic slope sites.

You can even slope soar large buildings that have big open parking lots. The wind still has to hit and go over that building. This creates great lift zones. And since you have a motor on your foamy you can climb up to get into that lift.

I live on Long Island, NY. We are surrounded by beaches. During the summer they are crowded with people but in the winter, our windy season, they are empty. There is all this beautiful water, then a beach then sand dunes or cliffs that the wind hits. I can fly an Easy Start hours on one battery pack.


The key is the wind direction and speed. The wind has to be blowing nearly straight into the hill. If it is more than 10 degrees left or right and the lift drops off fast.


You take your foamy, turn on the motor for about 5-10 seconds and fly out over the edge of the cliff. Gain a little altitude, maybe 20 feet, now turn the motor off and see if the lift will support your plane. If it does not you can always turn the motor back on.

I have gone slope soaring on dunes as low as 4 feet high and cliffs that are 100 feet high. I have flown my hand launched gliders, slow sticks and even a Vapor, in wind as low as 2 mph and have had to add weight to my Aerobird and Easy Glider so I could fly in 20 mph winds.

If wind has been ruining your flying day, you have to try slope soaring. You may discover you go looking for those windy days and start to grumble when the wind speeds are under 10 mph .

Try it, you'll like it!

Maybe I should go into the slope soaring forum and start recruiting them to switch over to powered flight...

No such thing as too windy, just the wrong choice of model.

You could try, but they have already discovered the holy grail of rc, so good luck.

Cheers,

True, it's probably the unlimited number of aerobatic moves that keeps them sloping... there's rolling and looping... some stall turns... some looping...

We do `tornado soaring' around here...

Here's one of the common models used...

yes, I am trying to take you over to the dark side. I am trying to show you how to use the force.


When I started flying with my Aerobird, my club buddies told me that there was no slope soaring on Long Island because it was too flat. But I found a guy who taught me how to slope my parkflyers. I just fell in love with it.

I have taken a lot of parkflyer pilots slope soaring. For some reason they think they need to take the motor our of the plane to do this. But I can't think of any reason to do that. The motor is always there to help you get out of trouble if you need it. And you can certainly run it if you like, but why bother.

These parkflyer pilots were just amazed at how long they can fly on one battery pack. And if you have an aerobatic model you can fly all the aerobatics you want. You can even mix in motor use with gliding to create a whole new range of aerobatics.

I am not trying to take anyone away from your electric powered flying. I am trying to show you that wind can be your friend and open up a whole new set of flying options to add to your flying enjoyment.

Once I started slope soaring I had to get a new, larger battery pack for my transmitter as I was running out of radio battery long before I was draining the pack in the plane.

This can be so much fun!

Hey Flatlander - you got any big buildings where you live? Slope 'em!

Many go into the slope forum but few come out. Beware!

See, a slope soarer at heart. Real men fly airplanes full of lead!

And the need for speed!

Been doing the slope thing all summer. Flying wings; IFO's and those profile foamies can all slope soar from what I've seen with my own planes.
I turn my ESC's brakes on so the prop doesn't freewheel and slow the plane down. Some planes glide better inverted too, like my IFO's.
Sloping is just another part of this great hobby, so try it.

Not many, especially after tornado season.

Wouldn't you need a permit for that? (Although I did see a video where Trappy did it.)

EDIT: Hmmmm, there are some large grain elevators around......

No slopes and no buildings, but lots of wind. I seem to be in a tough situation.

How steep and tall do you need a slope to be?

5 feet works fine. A retaining wall is good. Lake front.

I have actually sloped the roof of my house with my Vapor.
