Old habits die hard
Finally the right day with the right weather and right wind happened today. Here is the first time slope soaring the Radian. I have done it twice with the RP before. What a blast! You can see at the end it slips down behind a ridge upwind of my location. That wasn't where I planned on landing, so I hit the throttle stick to try and bring it back up. Nothing happened and then I realized my throttle-cut switch was on. I flipped the switch probably just as it was hitting the ground out of sight and ended up breaking the prop.
After a year of flying the Radian and RP, this is the first time I have broken a prop and the first time I have ever hit the ground with it turning. Hmmm...maybe there is a connection. Anyway, I figured it was a good day and had a couple of videos on the card and started hiking down the mountain. When I got about 2/3 of the way down it occurred to me..."Wait a minute, what do I need a prop for?!?!" I could have been still up there having fun in the wind. I never used the prop except to get out of trouble and all that got me was trouble. Oh well, tomorrow's another day.

I suppose that's the case for not putting on the throttle cut while flying. For myself, I lock the throttle when I first turn on the TX, during all ground handling and right after I land to prevent just what you experienced. I've been known to accidentally hit the throttle at the most inopportune times.

I learned a couple of lessons yesterday. One is to not let it get too far behind you where there is no slope lift. The other is not to get caught again thinking the throttle is available when it is not. I'm sure that all the purists who believe the prop is a crutch would get a good laugh out of this. |

honesty and openness
Jov: you said: ' I learned a couple of lessons yesterday. One is to not let it get too far behind you where there is no slope lift. The other is not to get caught again thinking the throttle is available when it is not'
thank you very much, Jov, for talking about your experience. it takes lots of courage to speak about your own mistakes, and if we are wise enough, it is of great value to hear what others have to say when they do wrong. it may mean that we won't do that too. there is a proverb that says: 'smart is he who learns from his mistakes; wise is he who learns from others' mistakes'. and this is 1 of the great things of this rcgroups, when we meet some1 that brings something that we all can learn without us having to do it ourselves. |

lazy 8's
'I concur... and propose a 3rd law of sloping.... "never turn into the slope" i.e. always keep the nose upwind. Don't ask me how I know'
not only when sloping. when gliding or soaring, whatever you are doing, don't do the full turn; do lazy eights, always facing the wind, so the plane doesn't sink. unless you are into a strong thermal... |

Phil, that's really not true. In most thermals circling is best. Unless the plane has eyes, it doesn't know if it is going upwind or downwind, only that it is moving through the air. If it's moving through the air at a steady speed, as in a circle, it won't rise or sink depending on which direction it's pointed in. Think of sitting in a balloon flying a glider around yourself. The problem is that when you are on the ground, you are moving relative to the air that the glider is in. It's like driving past a merry go round.
In sloping the hill causes the air to be doing different things behind it and in front of it. There are also situations where the air on one side of the circle is doing different things than the other side, as when your circle is not centered on the thermal. Besides the lack of lift, at many slope soaring sites, particularly ones where the edge of the hill is sharp, the air behind the crest of the hill is all stirred up, at least down low. This is usually called rotor. You can get this just downwind of a line of trees as well. Check out this gorgeous photo that Paul Naton put on line: http://glidefast.typepad.com/.a/6a00...32c9833970b-pi This would be fantastic slope soaring if you had the penthouse suite. However, landings would be tough. You'd have to catch it right at the edge, where there's a whole lot of lift to descend through, or land on the beach. If you tried to land on the roof, you'd get below that nice smooth curve and you'd find the air all stirred up. |

Many people, including myself, have had problems with downwind turns. Having said that, I believe it is only an illusion, and the problem is caused by the pilot trying to slow the plane during the downwind leg. |
