Well, I guess I have an advantage, having read the adventure (all of the posts, over just a day or so, so they all are 1story, conjoined, story. First, I did not quite get how/why the decision to go midwing was chosen. Perhaps just preference. High-wing seemed to me to less.costly, a main thrust of the project initially, (as I took it, anyway.) And simpler for the less skilled. Maybe it was an issue of 'public' perception. "No way... I'd be hanging, ready to fall, if I didn't ____ tight/well enough." Secondly, a pusher prop on fuselage spar was chosen. Many issues were raised. They were admirabley circumvented!!! Lastly, chains versus pullies fir said prop drive was raised and being a bike repair type I had to notice how chains were disfavored. Apparently they get very very hot in this configuration..I have not had time to mentally addtess the issue, yet. I first thought that chains are not usually subjected to a lateral wind. This would cause plate friction which is unusual. It now occurs to me that the speed of the chain might be greater than on a motorcycle. All moot points... Just things I noticed. I checked all links during the story. I could not get the results to open when it got the final approval PJK (or something)-1... nor did I see any final DNE or cruise or fuel data. Just curious. I have not engaged in UL craft recently, but got the bug again. I come from R&D and enjoy design, but am not to proud to borrow ideas. It was a grand read... sorry it ended. Maybe an epilog? Thanks, one and all!!! BillSF9c Near San Francisco CA USoA

Yes, Turbo... I was thinking of the entire project. Sitting atop a "fuselage member" would be fine, esp w a midwing. A topwing with bodyweight suspended, (how is optional) takes less material in tension. I like how you managed the eventual prop around fuselage, Desk... kept "cheap" relatively in the game. Optional 7/8 duct in the works? This is like the wingtip, adds efficiency! Maybe clear Lexan? I'm most sad more material.was not covered... yet grateful of only 7 pages to follow. Guess I am on my own. After decades on motorcycles, was (very)surprised about the chain heating and failing, issue. I wonder if wind, side-deflecing the plates, is why.

Ok! Pusher has some efficiency advantages! Maybe hurts the "cheap" aspect which was to be 1 hallmark. Yes, thrust is behind drag. True. Tractor seems obvious. But front wheel drive cars are more or less recent. Rear wheel thrust causes rare instability, "spun-out." V few boats use tractor. It IS behind you if you go down, so land on the tail in event of a mishap. Shocked at how few posts over several years, but they were good! I did designs when I was 11 in '61. Cardboard for fabric. Ha! Time to reinvent the wheel.

On catch-up mode. Read Vol 1 &7 and will read up. Did expect to begin w basic specs, such as wing loading, span, chord depth, landing speed. 80knots? As do not exceed, fine. If wing is high you can run an axle for pusher and tractor, but no counter rotating. Some advantages. Flex locates eng position along the shaft, but adds cost of 2nd prop. Allows front eng, push prop. Low wing better for ground effect, slow landings but high lends a dihedral-like balance. Pilot etc weight all hangs in tension - easier? New at this - forgive me. Might like larger dia (bike) wheels. Not always a landing strip. Fairings? Motorcycles are slow due to being aerodynamically dirty despite small frontal area. A half-fairing add-on is a nice option for speed or distance. BillSF9c

Hi. Is this the Welcome Pilots Just Landed? Or is Just Landed...Welcome, a Reply to the former? This is like is red in the right from the rear?... or head-on? I looked alphabetically. Would be nice if the annoying popup was a clickable TO the Welcome Forum..AND.. IF I need to start a new thread, that was said. I would have preferred giving a more intregingly Howdy, rather than begin w a gripe.or being simply confused. Start a New Thread, just to Intro? I want to study and come up with design parameters. Wing area for loading, hp req'd..et al. My aim is long distance, 2 hrs in the air gives a mere 33% margin and I need that at 60mph. Ride motorcycles and have done an intro flight. I don't do stoplight racing nor fast cornering (on asphalt) so there will be no tail-standing. Read about weights and 5 gallon rules. Near 'Frisco. BillSF9c
