This is going on an 1835 normally-aspirated direct-drive, on a high-wing 800 lb. gross low 'n' slow flier (90 Vne)...not a KR. Shipping weight, including the cardboards and packing, was about 7 lbs., so I'd guess the prop weighed right about 6 lb.- it sure felt sweet&light in my hands.

You want the correct amount. From a flutter standpoint, a little overbalancing is better than underbalancing. It will tend to dampen out any vibration. -- Don Reid Bumpass, Va. mailto:donreid@erols.com KR2XL at http://www.erols.com/donreid/kr_page.htm Ultralights at http://www.erols.com/donreid/usua250.html ---------------------------------------------------------------------- Subject: Re: [Re: Wing spars, (revisited)] From: Dennis Mingear Date: 15 Feb 99 19:26:18 PST X-Message-Number: 7 Hello Troy, I'm building a KR-1B and am very interested in building a plug-in wing.

I still have to say that you should use what ever weight it takes to make YOUR ailerons balance at 100%. On the other hand its just MY opinion and sometimes that aint worth much. :o) -- zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz Micheal Mims SP290 (Sky Pig 290) ,..Building Cowling now mailto:mikemims@home.com http://www.geocities.com/CapeCanaveral/Hangar/4136/ Aliso Viejo Ca ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ --- END OF DIGEST --- You are currently subscribed to kr-net as: johnbou@timberline.com To unsubscribe send a blank email to leave-kr-net-17800J@telelists.com
