    Thanks for posting the video Mark.  Who makes the instrument in the center of your panel with the artificial horizon on it?  What can you tell me about it.  Also curious about the reserve lift indicator.  What are your thoughts on it?  JImChuk

    The hysol is easier to mix at 1 to 1 ratio.  It didn't seem to last much over a year before it started to lump up though.  The scotch weld 2216 seems to be good still in 25 year old cans.  I don't use the old stuff for anything structural on the plane though, although when I've used it on other things, it seemed to be just fine.  To mix the epoxy by weight, I use a small scale like one of these.   I buy some plastic cups to mix in and popsicle sticks to pick up the epoxy and mix with.  Weigh the cup, add half as much epoxy to the cup, calculate how much of the other epoxy to add by weight, add it and mix.  Gives a perfect mix, and it's easy to do.  JImChuk

    One thing about this sort of drone engine though is if the gunners are good, it only has to fly once.  I want a few more flights then that if I'm flying behind it.  JImChuk

    Definatly a Rotax, most likely a 503.  There was a guy named Pops that flew his A model with a 447 though.  JImChuk

  9. 1avidflyer added a post in a topic Hirth   

    Day late and a dollar short and all, but to bad you didn't get that Hirth 55 HP I sold last summer when I helped a friends widow part out his Avid.  I had that engine gone through by the local shop that I use, they did a complete inspection, put new seals, gaskets and fan belt on it.  Had a gearbox on it also.  Sold it for $2250 plus shipping and I built the crate for free.  Had 160 hrs on the engine if I remember right.  I also sold his 65 HP hirth that had only 6 hrs on it.  JImChuk

    Interesting that this chart shows a 145 jet for the 582 DC.  I'm sure the CPS catalog chart shows 165 for the standard sea level main jet for a 582.  JImChuk

    looking at this chart, and doing some math tells me that a #50 drill bit is the same size as a 180 (1.80 MM) jet.  1.80 x .0394= .0709.   A number 50 drill bit measures .0700.   JImChuk

    I've drilled out jets for my Jabiru engine.  Need to used numbered drill bits most likely.  You could always work your way up if you need to go bigger.  JImChuk

  13. 1avidflyer added a post in a topic 3D Printing carbon fiber wing struts and gear legs and spars?   

    Years ago before I got into flying, I used to go canoeing in the Canadian boundry waters north of Mn.  I had a custom made carbon faber paddle made that weighed only 12 oz.  The guy made the shaft of the paddle just like this, on a tapered shaft.  He had some spare shafts sitting there that were maybe 3' long.  They felt like they didn't weigh anything, but when I laid one between two tables, I could put all my weight on the center of it without it breaking.  I think this would be a real good way to make wing spars, if someone understood what they were doing.  Maybe especially on an ultralight or hang glider type craft where weight is even more crucial then on our planes.  JImChuk

  14. 1avidflyer added a post in a topic Confused?   

    I'm using a lawn tractor battery that weighs about 12-15 lbs and it turns the Jabiru over good enough.  I think the 582 is easier to spin.   The Avids are known to be on the nose heavy side, so it's doubtful that you will be to far back on the CG with the battery mounted as far back as you can get it.  Kitfox engine is "right side up" but it is way harder to see over the nose on them then the Avid.  Lots of 2 stroke  engines have flown inverted for lots of hours.  I see no reason to go through the work of making a new mount and everything else to get the engine in the so called right side up configuration.  But this is experimental aviation, and so anyone can do what ever they want.  As far as widening the fuselage, I think I would remove the tube at the back of the door opening like was done on later models, install a new bottom door frame tube and then add the tubing like I did on my Avid and the Kitfox 4 to widen the fuselage.  I think you could go 2" on each side with no problem.  You would have to build new doors or remodel your old ones, but in the long run I think it would be worth it, especially when you give someone else a ride.  JImChuk

    My thinking is if you are going with the 582, there is no reason to stretch the fuselage.  You may want to put the battery as far back as you can to help move the CG back a bit.  If you look at the link I'll post, you can see how I did mine.  JImChuk

  17. 1avidflyer added a post in a topic Issues flying behind a 2-stroke   

    I should keep my mouth shut, but I'll add this to the mix.  At between 5000-5200 rpm cruise I would burn about 3 1/2 gph with a 582.  Cruise with the Avid would be 70 - 75 MPH at those rpms.  If one can afford an airplane, the cost of 3 1/2 gph of flying fun is not very much.  If a guy switched to an HKS, you could probably get it down to 2 1/2 gph and save $3 or $4.  I like to save money as much as anyone, but the fuel is probably one of the smallest expenses involved in owning an airplane,  Just my 2 cents worth, YMMV  JImChuk

    If your wings are uncovered, it would be a good time to put the little aluminum angle stiffeners  on the rib tails that carry the flaperons.  Check out this link, and look at the second to last message posted.  JImChuk

    Widen the fuselage at the doors at the very least.  I would probably redo the door openings so they would be just like the later model Kitfoxes.  (longer bottom on the door before it angels up and back)  That will make it easier to widen the fuselage.   JImChuk

  21. 1avidflyer added a post in a topic Friendly thrust competition   

    When I did my test pulls, I had the plane sitting on wood planks that were level. I would imagine that anything that would keep the plane from rolling (grass, mud, ect) would lower the indicated reading on the scale. JImChuk

  22. 1avidflyer added a post in a topic Friendly thrust competition   

    The Culver 74x48 is quite a bit of prop for a 2.62 gear ratio.  I had a 74x49 on a 582 with a 3,0 C box.  Avid supplied either prop with the 3-1 ratio.  I tried checking for static thrust with a scale like you have, and got about 305 lbs with the culver and did about the same with a 70" 3 blade IVO.  I've heard that even thought they claimed 65 HP on the 0-145, they must have been smaller horses then what the Cont. 65 HP engines used cause they didn't produce near as much power.  Never did compare a 582 with either of them though.  JImChuk

  23. 1avidflyer added a post in a topic Becoming a rejuvinated bird   

    I suppose that would work also Nick.  The only comment I would have is when the springs flex, there will be a little bit of lengthwise movement between the springs.  If that clamp is tight, it will restrict that movement.  If it's loose, it will work it's way down the spring.  Maybe the best of both worlds would be a slightly wider clamp that rides up against the tailwheel  so it can't slide downhill, but just loose enough to allow the springs to move.  But I do like the idea Nick.  Easier to do when a plane is already covered.  JImChuk

    I guess I was making a joke on the used paint thing.  (it's all dried out)  (is that what they call "dry humor"?) Nice thing about poly fiber stuff.  It don't freeze.  I always have some sitting in a unheated garage in northern Mn.  JImChuk
