    Engine Selection

    Another case of 'if it sounds too good to be true, then it probably is'. Anything more than a modest improvement over existing engines is probably marketing in an attempt to attract investors, nothing more. Still waiting on the Deltahawks to arrive as well! 🙄 In contrast, Aeromomentum is actually building and selling engines and gaining a very good reputation, I will continue watching their new engine developments with interest.

    Engine Selection

    Yeah, the numbers I'm getting are between 72 and 77 g/hp/h or about 0.16 lb/hp/h Way too low. I expect real world consumption should be like triple that!

    Engine Selection

    That diesel is a 'dream' for sure. If I'm doing my numbers right, those sfc numbers are twice as good as the best high-efficiency diesels in use today - and I'm talking power generators and huge ship engines, which are much better again than their smaller counterparts!

    Engine Selection

    In consideration of the wise words of people like Chris (and a few others) I've decided to limit my search for powerplants to complete FWF (or in our case FWR?) kits. I like tinkering, but I like flying more. Having a unique engine setup means having unique problems. Much as the price of a roll-your-own automotive conversion is attractive I just don't have the mechanical knowhow at this point to treat that as a realistic option. That and there's no way my wife will get in if I do! A few more engines on my watchlist: Aeromomentum has added a couple of engines to their selection. A naturally aspirated version of the AM20T which at 170HP might be right for a Cozy. There's also an AM24 now, which depending on weight could be very nice as well. No details on these new models as of yet, but the AM20T is advertised as 260HP for 285 lbs with a price tag of 19k, so that should give some indication. Any fears I had about the engineering of these machines have been put to bed after digging through forum posts and youtube videos of Mark Kettering. He's done his homework, and he doesn't seem the type to overpromise and underdeliver. Tons of testing, and seemingly nothing but happy customers. The balkanization of experimental aviation never ceases to astound me, as I just discovered that the gyroplane guys have been flying Yamaha snowmobile engines since about 2013 and fixed wing guys are just getting in on the action! Mohawk Aero Craft has made a kit from the 998cc Genesis Turbo engine from the Yamaha Sidewinder snowmobile. I gather the power clocked in at over 200HP sub-200lb weight (I remember reading 204HP and 170 lbs, but I can't find the source now). Only one flying right now, though about 20 more with other Yamaha engines. Greg Taylor Mills seems very knowledgeable and enthusiastic, and I think has a genuine desire to advance the state of experimental aviation. My concern with this one is that there hasn't been a lot of testing, and none of the guys flying these things seem to have more than a couple hundred hours. Ten years ago the auto conversion True Believers like all the Subie guys (and I'm not talking about the Egg ones here, that's another story) thought they were launching a revolution until a few hundred hours later crankshafts started to fail... Scared a lot of people off. No failures on this one as of yet, and it is definitely one to keep an eye on. A > 1.0 P/W ratio is a big deal! I'm still keeping the Diesel dream alive. P2M, an italian company, is advertising a line of diesel engines and is trying to get certified. Actually saw one bolted to a LongEZ on another forum (there's that balkanization again). All of their specs on their website are in metric, but the translation is this: The JPE01 engine is 150HP and weighs 220 lb, burns about 3.7 GPH at full power, and closer to 2 in cruise. The JPE03 is 220HP and weighs 345 lbs, burns 5 GPH at full power and 3.7 in cruise. I would avoid the 02 and 04 models as they are Hybrids. They bolt on 88 lbs of electric motor and battery to give ~30 minutes of 80 extra HP. Juice that in my opinion is not worth the squeeze. That's a lot of added weight and complexity for extra power at takeoff. Anyway, these seem like "glossy brochure" numbers and I'm sure the price tag will be astronomical, but they're supposed to be at Oshkosh this year, so we'll know more in July. They have a distributor in western Canada but it sounds like they'll have an American one this year.

    Kent's Long-EZ project

    The wrap on the CHT probes is a fiberglass braid that came on the probes so I used it. It is tie-wrapped to intake tubes in the pic so the extra braid is probably not really needed and it absorbs oil. Since then I make my own CHT probes using fiberglass-wrapped wires. It is pretty tough stuff. https://www.canardzone.com/forums/topic/18661-kents-long-ez-project/?do=findComment&comment=61850 The caulk is GE Silicone II https://www.acehardware.com/departments/paint-and-supplies/caulk-and-sealants/caulk/1092691 Clean the fins first with some lacquer thinner or acetone Squeegee the caulk into a layer of BID between plastic, cut to fit and stick it place. . It will stick well and can be trimmed with a razor knife. Yes, two Lightspeeds. I have been thinking about going to Earth-X batteries and save 40 lbs but they are SO expensive. Still, they're said to outlast 3 of the SLA batteries.

    Kent's Long-EZ project

    Thanks for the photos and ideas... what is wrapped around your CHT probe leads? I don't have that wrap... is it needed? On your silicone wrap on the cylinders... what kind of silicone... the plumbing stuff in the caulk tube? Is it used with BID / UNI? What keeps it in place? I've never seen an EGT probe that close to the exhaust port! Do you get descent service life there? (not saying its bad, just wondering) Looks like you have 2 LSE ignition systems..... that correct?

    Kent's Long-EZ project

    My Uavionix EchoUAT and SkyFYX-EXT are showing targets but apparently I am not putting out data. I thought maybe the problem was old software in the Garmin 327 but $180 and a software update later, no joy. I have asked Uavionix--waiting for a reply. It somewhat frustrating that there is no troubleshooting information on their site. It could possibly be a wrong setting in the App. Greensboro approach told me my UAT was working but I can't generate a performance report. ------------------ Odds and ends: (1) How many times have you installed the flywheel and prop extension, maybe the prop too, and --duh!--you forgot the alternator belt? (2) Here is how much fin space I allow on the bottom of the cylinders; seems to be about right. (3) A picture of a wrap made of silicone sealant from the home stores. It holds up well there. Even around exhaust pipes, it will last a long time before it gets old and cracks. (4) A method of attaching the additional filter and fuel lines on an Ellison. I installed the fittings, then packed the tube with sand and bent it. You could try to freeze water in the tube or use an alloy made for bending tubes https://en.wikipedia.org/wiki/Wood's_metal If you use sand, pull a cloth through the tube to get it all out. (5) I like this quick way of attaching wires to engine mount tubes: a wrap of baffle seal material and a tie-wrap. (6) Finally, I am working on a spare 2-blade prop for the Cozy.
  14. Good info. Bill did post some pictures on a FB page but has not offered many details. Not sure how serious he is about selling it? Typical airplane pictures: looks good on outside in pictures (they have to be pretty bad before the pictures show it). Looks like the interior and avionics are a bit dated. Yes the weather on the West Coast has been a bit off this winter. Shadowing a CI would be great. Maybe I could talk Bill into stopping in at O9CL on the way through... Understood about time and money to build vs buying and flying. That is certainly a factor in considering this plane.

    Bulkhead cutout finishing

    Not mentioned... My experience/policy dealing with foam and fiberglass construction is that before paint, at the latest, ALL foam MUST be sealed. Too many primers/paints out there that eat too many foams otherwise.

    Considering Long...

    Bill has been trying to get the plane down to me for a Condition Inspection for months now, but between his schedule and the weather, we haven't been able to arrange it. It's still in the plan, though, as the weather improves in the spring. If you're truly interested in the plane, you can work with Bill to be here when the CI is done, so you can learn about the plane (and Long-EZ's in general). At this point, you can buy a flying Long-EZ for about 1/2 of what it would cost you to build one. It won't be as nice or exactly what you want, but it'll be flying 3 - 7 years earlier. All depends on what's important to you, what you want, and what your mission is. And you can upgrade/modify it to BE what you want over time, while it's flying.

    Considering Long...

    I have seen the ad on that one (N8HA) but never see any pics or info. https://www.canardzone.com/forums/topic/21972-sales-ive-seen/?do=findComment&comment=62563 I suppose his price for an '86 O-235 airplane ($32K) could be reasonable but she (his wife apparently) has been trying to sell it since October. I just shake my head when the the seller doesn't post any pics. Here is a post on how to find other canard owners that might know about the airplane or would look at if for you https://www.canardzone.com/forums/topic/33309-varieze-builderpilot-wanted/?do=findComment&comment=63092 Lots of canard flyers in the S. Cal. area and they meet regularly at Chino for breakfast.
  18. One of my bucket list items has long been to build and fly my own airplane. To that end I have made a few significant life course adjustments from time to time to make it possible. There are still some scattered clouds but things are opening up. Part of this is deciding what plane? The Long is one of my short list interests. I'm not exactly always conventional and like a good sports car and the Long tickles both of those. I have worked with foam and fiberglass and know that part is entirely doable. But then there is the build vs buy. I find myself considering a particular Long (8HA) that is relatively "in the area" (Northern Ca) and could use some education. Anybody near Grass Valley/Auburn/Folsom/Sacramento area who might be interested in sharing some advice/experience? Thanks in advance.

    Cozy plans and parts for sale

    I am asking $300.00 for the complete set. I believe I paid $500.00 at the time I purchased them. I called the supplier and they now sell for $795 canopy and $300 for the side windows. These are the clear acrylic. When I purchased them they were shipped by truck, that was a $40.00 charge I do not know how much it would be today. If your interest call me at 734-559-4580. I also have the spruce kit and hardware kit (nuts & bolts), pilots manual and complete plans set and news letters.
