  1. Pardon the dumb question. How can you get all of that HP out of a turbo'd engine with a fixed prop? It seems if you set it for say 2400 rpm on deck, won't you overspeed up high? Or were you considering an MT or something like that. Another thought, you could use high compression pistons, I know of at least a few Mooneys. Run rich and limit MP down low. Up high, a few extra inches. Bob
  2. <<It is faster and more fuel efficent at the same time.>> That's no surprise, speed is the numerator of efficiency. 1. The L320 can use flaps to reduce landing speed, the Cozy designer has to increase wing area 2. Two fixed gear legs 3. Shorter fuselage, more of a blunt tail 4. Fixed pitch prop 5. More interference drag from intersections 6. Less cooling drag? <<As a tail dragger it should have a dissadvantage to a canard in general.>> ?? Don't know why this would be true, but even if it was, the L320 is a trike.
  3. In my canard exploration I stopped by the EZH last fall on a biz trip. Talking to Rob, my understanding was that the missions of the jets were recreational, not for serious travel. I think they said the idea was they would be a lot more expensive than an L-39 (300K?) but much cheaper to operate. Although I was concerned about how overpowered they would be I was impressed with the thought he had put into safety features like throttle horns (a la AB stop in a mil a/c) to help the operator from getting too fast. I think it was designed so the plane would not go faster than about 200 indicated - level - without going around the 2nd horn <<Greg Richter is putting a jet engine in his Cozy>> Bob Miller St Louis, MO ...looking at EZ's
  4. Thanks very much for the input. I should clarify a few things, 90% of my IFR is over the forgiving Midwest, I don't plan IFR out over the rocks or cold water. The other thing is that with 4 kids, it would be really "Cozy" for my whole family (and we are in the process of getting a dog). So we are really looking at a bigger plane (partnership) for family and frankly for business I doubt many of my colleagues will want to get in something that looks like a surfboard. I didn't realize that there were many Cozies that had more than a Lyc 4-banger, although that would actually be my preference. I have a hangar neighbor who will be selling a IVP (it is gorgeous) but I don't have the means to maintain something like that. Thus the IVP is not really even in my long range plan unless we are talking lottery, etc. For me, a little pocket rocket for the 60% of biz trips that are solo would be nice. I would imagine that the IFR chart management in a LEZ is pretty analagous to what we did in the TA-4J in the Navy. I temper my wx minimums with the type of environment we are in, here in the midwest it's pretty much fire it up and go direct, farms and large lots are available for the forced landing. <<weather related government agency that uses a slightly modified LEZ for weather research>> Isn't that the LEZ that went down when the pilot had a stroke? Again, I have a lot of respect for you guys who make time to build. For me work, 4-kids, grad school at night, is plenty. I went down to the airport yesterday to put my oil cooler blocker plate on the Mooney for the winter but never even got to it, after I flew the I was out of time for the day. I was lucky enough to air up the tires and sweep the hangar. Cheers, Bob
  5. Thanks Jim. Since we have some thoughts in common can we focus on LEZ versus COZY? It seems most of that comes down to whether the spouse is comfortable flying in the backseat? <<Wife hated it.>> <<Not suitable for IFR>> Because of lack of room and lack of support by GIB?. Or are there other reasons? Why - most of my XC is IFR <<Cruising at over 180 kts at under 10 gph is a GOOD thing.>> 180 ktas on Fixed prop, 66% fixed gear, no flaps, 4-banger normally aspirated engine - amen Thanks again, Bob Miller
  6. I appreciate your loyalty to the type; just wondering what were the key features that drove you building a COZ/LEZ. Say perhaps it was the price of a plans built kit. If that was not the issue, would you still be building a COZ? Or put another way, something you can post publicly, "top 10 reasons to buy/build a COZ rather than a Lancair/Glasair". I have read the CAFE reports, etc. To stir the pot, I'll try to do a pro-Lancair list: 1. Faster 2. Designed around 6-cyl 3. Possible CS prop allows better util of turbo 4. bigger (wider/taller) cabin? 5. slower landing speed? 6. more preengineered parts 7. side by side seating (Coz also has) 8. higher resale Again, please forgive my being a devil's advocate here. My top choice at this point is the canard a/c. Also my admiration for the builders....Private replies welcome, make obvious changes to e-mail address. thanks, Bob <<Cough... COZY! Cough...>>
  7. Hello Canardians, thought I'd stir things up a little: Interested in comments on purchase of LEZ vs. other types of exp (Lancair, Glasair) for light IFR for personal transport. Fly about 250 hrs/annual for business currently. I have been thinking about selling my Mooney for a year or so. I have a large family and access to six seat aircraft so 3rd and 4th seats of the Moooney are not a big loss. so far I have the following: LEZ: - $40-60k for a nice one - simplest of the three (lowest op cost) - best midwest support (EZ Hangar, EAA32) - 165-170 ktas - best type club comraderie (rough river et al) - unusual planform (interesting) - tandem seating good for form - light icing might fall into prop - high landing speeds, 3000' strip or greater Glasair/Lancair - higher purchase price $80-120K - retract/controllable prop, retract gear = >$ - side by side (good for wife, pax) - 180-240 kias? depending on motor - better panel for panel candy - look out for small tail 320/360s neg static stable in ldg config - questionable support on Glasair? Mooney - 155 ktas - very stable, easy to fly partial panel - big panel with a/p, wx900, gps, etc etc - manual gear - 4 seats - smooth airstrips down to 1500' - metal roll cage, good off-field landing history I am especially interested in comments on builder/owner support and flying qualities on the Glasair/Lancair compared to the LEZ/Cozy. My dad's neighbor built a Glasair in the 80s and flying it with him was a little bit of a disappointment esp considering the time and effort (pitch too light, roll too heavy, not fast as advertised). If I got a LEZ, the plan would be to build a 2nd one at my leisure to better understand the craft (and because I like building things) Thanks in advance for comments Bob Miller St.Louis, MO:)
