[RCSE] Angle of attack question...

2002-08-16 Thread h_k_russell
What kind of angles of attack do you guys think a wind sees during normal sized, high speed circles?? I'm think on some foils for a DS specific plane and have been thinking that the wing might see 10'-12' AOA. I'm pretty useless at math (and most other forms of higher thinking) so I'm hopin

I am also an archer and there are a fewe things you should be aware of when using a release. 1) They don't like to be bumped when they are under load. If your glider gets a rough tow up, the release might go off early. 2) The good ones are adjustable by a little set-screw under the trigge

> How about experience with 225's ? I have had two (3?) HS 225's that have died suddenly. One I was adjusting the pushrod and when I hooked it back up, it was dead... no warning. Died with far less than 50 hours on it. This was an elevator servo. The other on was new, less than 5 hours, and

Buy-n-fly is great, it allows people that are crappy builders to join the hobby. The more people the better (with a few notable exceptions). I design and build all the stuff I fly and I still feel like a hack flier just trying to get by. It's great if a person can afford to buy a nice plane

No matter what color you paint a plane, it will end up black when highlighted against the sky (Mr. Murphy said that). In addition, I guarantee that if you try to paint the bottom of a wing a very visible color (like OSHA safety purple, for example) it will absolutely disappear in a beautiful

Square or circular joiners I don't see a difference except that round rods are probably easier to find. Carbon or steel Carbon is lighter and more expensive Steel bends before it breaks (I think this is safer) Carbon just breaks floating or fixed rods a fixed rod t

I've seen a Hades DS'd before with 85 plastic geared in the ailerons (I've been told that plane did about 130 mph when fully wrapped up). 225 is probably too big for most planes (depending on how extreme you fly) and add unnecessary weight. Plastic geared servo's don't have much slop and won'

Yep, it was the Kestral. Met him only once as he was walking up Shell Ridge in NorCal. The machining was just amazing, WinchDoc did some nice work. I wish I had seen the plane fly. I know that I could never build a pitcheron plane now that I have seen the workmanship that went into that on
