Hi Doug, Glad you came to play! I don't know, I'd be worried about exhaust inside the tailboom. Even though the carbon fibre would handle the temps, what about...
Been beating an idea around in my head and more i think of it, the more i think the simplicity of it might work. Anyone ever tried a motorcycle engine mounted...
Too heavy budd. When flying inverted, down is up and up is expensive . ... From: Chop doc <chop_doc@...> Sender: Janowski@yahoogroups.com Date: Wed, 1...
I'm curious. Been reading a lot about the group discussing power plant alternatives. I'm sure your all aware of Rotax. They put out tons of power and are...
Daniel: Like this? http://groups.yahoo.com/group/Janowski/photos/album/13851782/pic/1591666308/view?picmode=&mode=tn&order=ordinal&start=1&count=20&dir=asc ...
Very much so Michael, but with a V-belt drive. Mechanics at a Harley shop told me that a chain is good for about 12K miles, yet a V-belt can be used for 70K...
Mike and daniel: Is it possibible to mount a 503 low like that with the J1? I like this KISS. Make the plane look neat and clean and would also allow for the...
Kirk: Just curious. Have you looked over the J1-B for rigging problems yet? Dave didn't build it as I remember from past threads. Is it possible that the...
Jerry: Excellent suggestions regarding the rigging on C-GUMP and you are right on point with some of my thoughts when I first read Dave's reports about his...
Daniel: Yes and chains are heavy, noisy and do create greater friction issues as well. I question though what about stretch issues on long V belts like that? I...
Michael: Do they use coged flat or the flat ones with the little v's under them? I am trying to see from the photos of the small geo metro redrives. I will...
Michael, with my experience of the Harley V-belts, they dont stretch. I am due my 10K checkup now and no play at all in the belt. Wish tires lasted that well...
Jerry: Hey thanks for the great info. At the moment, I'm on nights and the J1 fuse is outside in a car port. Wings are I'm my hallway lol. Its -10 and getting...
Ahh hell. Not you all got me thinkin. Ill report back in 20 minutes. Heading out to take some measurements and check the angle. Kirk When flying inverted, down...
Jerry. Out side and cold as hell. Sadly, the angle is approx 3 to 5 degrees from 90 to the mail bulkhead. Its angled back just a tad. So the leading edge of...
Kirk: Don't freeze to death. The information can wait. I live down here is Sunny Florida. It got down to 53 here last night. Brr!! You would probably be out...
Jerry, Kirk & all. You got me thinking and I examined my plans and manual for the J-1B. The second page for my plans shows a "45" (mm or deg?) figure...
I put some pictures in the files section here about the discrepancy. http://groups.yahoo.com/group/Janowski/files/J-1B%20wing%20AOA%20%26%20bulkHD%20angle/ ...
Jerry: I think you are on to something here....need to run and go find the Jan issue of Kitplanes.... As you noted Alejandro also had limited pitch authority...
Michael: I just measured mine that was set at 2 1/2 degrees and I get 60mm Difference from the trailing edge to upper longeron versus extended airfoil bottom....
Jerry, Mike and all This is getting complicated. My J1 is built. Finished. I wanted a toy I can fly around in, not an aircraft plauged wiith design issues. A...
Kirk: Sorry!! Did'nt meen to upset you. I'm an ex engineer and get a little carried away with perfection. Don't get the idea that your J1 had any major...
Yes ... I just got an answer from Alejandro... his has the bulkheads as per the detail in the instruction manual at 2.5 degrees relative the top longeron, and...
FWIW.... Alejandro said that he tried changing the angle of incidence of the horizontal stabilizer both up and down and it made little if any difference....
Mike: Thanks for the boost of confidence. I had a dream last night. "Skyshark" was done. (My J1-B). I was taxing our to rwy:2 at a local airport. I lined up...
