I'm also working on a 3-D drawing. I should have this done shortly and I'll post these to you. Are you interested in building your own drive? Mine has aprox 20 hours on it now and all is still well. regards Carlton >> Good Morning ! At least it is morning right now for me. I've been thinking about it for a while, but haven't found anything that I thought was rugged enough and at the same time light enough to do the job. The weight penalty so far is too high to pay for the horsepower gained.

I wonder if anybody has, or can point me to, information I'm sure I've seen somewhere on how to make a little wind-driven dynamo or generator for airplanes without electrical systems. It's something like whittling a small wooden prop and attaching it to a bicycle generator or something, and it hangs out in the airstream to produce just enough juice to power a radio or charge batteries. I think the guy who dreamed it up had a retract mechanism to allow him to pull it into the fuselage when not needed. Thanks!

Well, one of the cross members was broken by accident as I was working inside the boat. The glue joint held and the wood was the material that broke or split. I have since broke some of the other test pieces that I put together and the results were the same. Yes, I will use a structural epoxy for the glass. But I feel confident about the wood work. I made a special concentrated effort on all of the joints. I thank every one that had an input in this regard. The best to all and happy building and/or flying.

The vacuum venturi tube (available commercially in different sizes) can be located inside the cabin with a NACA scoop supplying air or outside in a pod. Just a bare tube will create a lot of drag. Then that vacuum to power a small vacuum driven motor coupled to a generator. An old vacuum driven gyro could be modified with a permenant magnet DC motor to do the job. I would assume that a fan spinning outside will generate a lot of drag. However, it has been used before on Komet 163 (?) fighter in WW II. On the progress front. I have have day today and two weekend days to finally finish the boat (famous last words).

Their phone number is (626) 796-2628. They carry all kind of small motors, limit switches, gauges, transducer etc. Long time ago I bought a vertical gyro from them (savlaged from a bombsight) and had a lot of fun with it.

I'll have to look through my stash to see if I can find it. I'll let you know if I do. BTW, I'm new to the group. I'm still only halfway through the archives of KRNet, so I'm learning a lot about building KRs. I'm hopefully going to be buying plans in the near future. I'm glad to know there is such a great resource to tap into once I start cutting wood and glassing.

They make aftermarket ingnitions for autos and they make a product AccuVolt. They advertise constant supply -+.1 volt you can get 14 or 16 volt output at 25 or 50 amps. Summit Racing Equipment 800-230-3030 sells the 25 amp for $222.99 and 50 smp for 265.99 That is out of a Feb 1999 catalog.

I have one on my Luscomb. I know there is a lot more drag there to start with but the generator only takes off around 2 mph. There are a lot of the generators now that have the prop facing aft I understand those are almost undetectable as far as drag. I mean how much does a set of wheel pants slow you down. The problem is making sure the rpm is right on the generator. And by the way now days an alternator is the only way to go. ---------------------------------------------------------------------- Subject: Re: EPOXIES From: "w.g. kirkland" Date: Fri, 14 May 1999 17:34:13 -0400 X-Message-Number: 10 Greg Why switch. I'm doing the opposite.T-88 for structural and West for the fiberglass. So far the glasswork has been fine. Yes I broke a spreader the way you did and got the same result. My problem is I'm pretty sensitive to the West Hardner . West wets out the glass very well. W.G.

I coated all my bolts with bees wax. Paint is too thick and you wont be able to get the bolts thru the close tolerance holes in the wing attach fittings.

You'd lose some airspeed, but the plane would not have an "engine driven electrical system," so it would not be required to have a transponder to fly in the Mode C area of Class B airspace (but it couldn't fly into the Class B itself, of course). I think I've seen pictures of some wind generators available as surplus. >How about generating vacuum and using it to drive an generator.

Then that vacuum to power a small >vacuum driven motor coupled to a generator. There's something in one of the old Newsletters about a guy who built a venturi inside the wing so there was no drag on the outside, but only the drag through the middle. I think it was built into the fillet between the stub wing and the fuselage to avoid having a hole through the webbing of the spars.
