    What is worth a few pounds?

    I'm all for the ergonomics and such. As for the BRS, in anything that I had a hand in it is almost not even an option. I barely trust myself to design a kite. One additional worthwhile place to add weight is instrumentation. Even the super light guys can benefit from a GPS, Com. I love the...

    Things to do in Oshkosh for non-aviation people?

    I wanna go to Airventure... I've never been and damnit I wanna go. I'd like to bring along my wife but she is not into aviation. She is supportive of my dream but she worries to much, i'm kinda hoping that seeing all the airplanes operating safely and such will help put her mind at ease. She...

    Dihedral question

    Amen Brother... A while ago I was discussing the possibility of controlling the entire wing surface as an aileron. A vast amount of good information on freewing design came from that discussion. I will try to find a link and edit it in here momentarily...See I can be responsible...

    Aileron Design - What works and why?

    There is really not a lot out there about the free-wing control behavior... A couple of like you say UAV sites and a couple of old patents with little info on behavior. Mostly googling free-wing comes up with lots of free wing-chung classes, free wing commander t-shirts, and free wings at...

    Aileron Design - What works and why?

    What about Wingerons? Rotate the whole wing arround the main spar. You'ld get flap like behavior. You could pitch nose down/up without changing AOA on the wing (might be a visibility boon for taildraggers, but could also screw up visual referance). You could trim the wing incidence vs fuse...

    Aileron Design - What works and why?

    That takes care of #3 changing the x-section of the airfoil to provide control and to suit vairous flight regimes. I'll elaborate on ideas 1&2 here because I really did not convey them too well. As they are just different ways of achieving the same goal. (I suppose all forms of roll control...

    Power Tool Manufacturers

    I have heard a lot of good and bad about the Jet tools it seems that people either love 'em or hate 'em. A while back I found a great deal on a lathe, planer, drum sander, and table saw that were going as a set at auction, they seemed to go really cheap. After that I asked arround about them...

    Aileron Design - What works and why?

    Very well Billski, in that case I shall continue my assault on all that is practical and sensable in the world of aircraft design...;) Billski made the point earlier that the LE device would tend toward the hard over position at any deflection (a point that I completely neglected). This...

    Aileron Design - What works and why?

    That is good to know, especially since I'm in 172s exclusively until I buy/build! Note to self: Kick out the slip before trying to flair! I would think that delta CL of 0.2 is plenty for an aileron, insufficient for flaps maybe. Is there a minimum dCL suggested for ailerons or a performance...

    Aileron Design - What works and why?

    Ok, Given you will have an increased weight and complexity with both TE and LE surfaces vs. however with LE only ailerons that would be minimized... Also, with regard to complexity, this would also probably require some wierd airfoil shaping in order to keep a laminar flow (if your worried about...

    Aileron Design - What works and why?

    Orion, would this qualify as an argument against flaperons? Wouldn't the positioning of the "flap" would be somewhat dynamic as the "aileron" changes position. Therefore some of the sub-optimal "flap" tendancies cancel out the effect of some of the "aileron". OR, am I way off base? AND...

    Up to the fourth flight

    Wally, I don't know if you've painted it yet but for inspitation there is a beautiful black one on barnstormers. Looks like its a medium gloss. ohhhhhhhh.

    New Drawings Need Design Refinements

    Its a KR2S variant... and I am so interested to know how the development is coming... KRs are **** sexy little beasties.

    Transform wood fuse to steel tube

    I can't claim to know too much about the conversion process, however, some months ago Orion scolded me for suggesting to change the spar on a KR2 from wood to steel indicating that it would require a neer complete redesign. My guess would be that this would be in the same category of...

    Flying Vertical Stab

    I don't NEED to do it... but then I don't NEED to do a (pseudo)Fly-By-Wire either...;) Maxon motors makes some brushless wash down 12vdc gear motors with encoders. They had some great torque to current curves, good speed, are pretty light(used on space vehicles according to rep), and have a...

    Flying Vertical Stab

    I was thinking of using a KR2/2s as a basis for the system. Do you think that this would be too much go fast for the flying stab of does it fall into the easier category. It seems like it'ld be a lot easier/lighter/more efficient to do the flying tail from a parts count POV any way. My...

    Flying Vertical Stab

    The idea for an all flying vertical just came to me after reading a few posts re: flying horizontal stabs (stabilators). Has any one heard of this being done. A quick google "flying tail" only came up with some WWI Fokkers and a movie about a horse, and I dont have time to investigate...

    Hello, new member looking at KR's

    I'll see what I can do so far as the altimeter is concerned. There is a reason that the Collins is a big box though. Are you volunteering to flight test a system if I can come up with something?

    Hello, new member looking at KR's

    1. Thanks for the vote of confidence on the decision to mod the 2s down to a single seat rather than bump a 1 to allow me to fit in it. This gives me some more confidence that I am going to make the right initial decision. 2. Yes I misspoke unstable is not the word I was looking for, and...

    Hello, new member looking at KR's

    The FBW thing is not an absolute necessity but I figure that I may as well put in some stuff that I know... I really don't think that it would be that difficult to do though, being that I've been doing electromechanical control SW for the last 8-10 years. I think that the only real issue for...
