Back to airplane-chat, I bought plans for the 4-seat Bearhawk (#1366)!



I'm hoping I can finish this in, say, under 15 years.

Helno I spoke to someone about your lazair because I think it's cool, it's like you hung a hook in the sky and now sit on a seat just floating there... but this guy i know asked what the Vbg of your lazair is?

I've never specifically tried to get best glide for distance because I move so slow it is pretty meaningless. Minimum sink is around 28 mph so best glide would be a few mph faster.

Most Lazairs lack the instrumentation to properly measure things like that. I know I got a huge increase in climb rate with my bigger props because I am not relying on butt dyno.

Congratulations on getting the plans for the Bearhawk Ehnus. Building one is something I probably will never do I like flying them to much.

Wish me luck on the prepurchase inspection.

For a second I thought this meant minimum unpowered descent rate was 28mph (2464fpm)

Awesome, should be a fairly different ride to the Lazair! Best of luck with the inspection, I'm sure it's at least a little nerve wracking.

Nice! I started (and soon aborted) a Pitts S1-S a few years back, and am keenly looking at Hatz Classic plans now. What's the build like - chrome moly fuselage and Al wings? Any cloth? It's a huge task, best of luck to you too!

I like the "one axis control" on the ERJ-175. It's the one labeled "AP" on the flight guidance panel.

In non retarded afraid to fly an airplane until I mitigate all risks out of being barely high enough and fast enough to kill you land, that bearhawk looks like a sweet plane. The name even is cool. Kinda a STOL, rugged back country type of plane?

Yup, 4130 fuselage and aluminum wings. The control surfaces and fuselage are all fabric covered.

Although since I last posted my son was born and I've been wondering if hammer forming and riveting is something I should, y'know, not be doing in a workshop that's attached to the house. Especially since the only time I have these days is in the evenings after everyone's gone to bed. So, I'm not sure if I should continue down the Bearhawk path, or go with a Cozy or something where I can work for a few years without requiring an air compressor.

Kids get used to noise if they're exposed to it. They get tired and have to sleep; it's a biological imperative.

Well, yeah, but air riveters are pretty loud, no? He deals well with noise, at least compared to some kids I've heard of, but there's a difference between sleeping through people talking and periodic 100db percussive riveter blasts on the other side of the bedroom wall. My bedroom also shares a wall with the shop so the wife might have something to say as well.

I could be wrong. I hope I'm wrong. But I don't really want to sink a couple thousand into tools only to find out that I'm SOL.

Yeah, kids seem to take time away form projects like this pretty well. You could always work on something quieter for a while, like jigging and prepping the fuse - but it sounds like it'll be a while until you can go full-noise.

Of course, if you're after a quieter project, there's the Flitzer...

It's now official. Inspection went very well. mechanic found a few small things but all are things for the next annual. Prop is in spec and no bad news in the oil filter.

Now we just need to get the plane from Nova Scotia to Ontario.

The local airport is being shut down so we got it for a steal at $30k CAD. 4100 TTAF and 640 SMOH

Neither me or my new partner do.

We might think about installing an older IFR legal GPS if he wants to pursue it.

Heading to Oshkosh next week. Got a pair of freshly minted CPL's coming along for the ride so it should be interesting.

Fixed up some broken headset jacks and built a ghetto bluetooth audio input system for it.

£110'000. 180hp IO360, 3 axis autopilot, good avionics (mostly glass), 3 blade mt constant speed, tip tanks. The attractive part is the minimal maintenance costs and being able to do it yourself.

Until the window is repaired there wont be much flying going on.

It is frowned upon to patch a certified plane with duct tape.

Our annual is scheduled for two weeks from now so we are just waiting on the insurance adjuster to figure out how this will be delt with. We will get the windows installed during the annual (we will probably install them ourselves under the supervision of our mechanic).

Yep, I think so if you're a bit involved with them. I'm certified on the husky but try to be involved with the maintenance as much as possible.

There are certificated ultralights if you expand outside the strict Part 103 ultralight definition. Like the Revo weight-shift trike I keep lusting after that can be certified as S-LSA (or E-LSA if you want to keep the freedom to tinker).

I guess I should update this to keep it out of the archives.

Fixed the windows and a bunch of other stuff during the annual. It was a great experience seeing every part of the plane and confirmed everything about the prebuy inspection.

Have done a fair bit of flying but no really long trips other than a run up to North bay.

Partner isn't flying right now after laser eye surgery but lovely weather is keeping me on the ground.

Well this is a different update. Been doing a ton of aviation stuff since the last update. Got pretty into the Srratux ADS-B project and have been selling parts since Oshkosh.

I sold the Lazair in the spring. I hadn't been flying it and going to Port Elgin to do so was a pain in the rear end.

I have been wanting to do an electric aircraft since I saw the electric Lazair but wanted something a bit more capable so I bought this.




Monnet Aircraft Moni motorglider. I saw an old listing for it and figured he might take a pretty low ball offer since it needs work and he did. Drove out to Quebec to pick it up and trailered it home.

Built in 1987 by an AME (Canadian name for an A& P) with just under 120 hours on the aircframe.

Engine needs some work. It came with four one in pieces in a box two in unknown condition but assembled and the last one is a brand new long block with a reduction drive.

At least two of these engines have broken cranks which from the logs appears to be due to prop strikes.







So the current plan is to remove the reduction drive on the new engine and get it flying. After that convert it to electric power probably using a Lynch motor.

So I cant actually start working on this plane quite yet.

Need to get the garage finished so I can bring the plane in so that takes priority. Insulation and vapour barrier is up and the drywall guy starts tomorrow so things will happen pretty soon.

In the meantime here are a few pictures of the other bits.

Here is the lovely new longblock. Sadly it will be losing that sweet reduction drive.


One section of the steel ballast weight. I guess this plane was originally designed for a much heavier motor and it needs over 50 lbs just behind the motor to balance.


Fancy wrapped exhaust. It is very long despite not being a truely tuned pipe.


The very small Sterba prop. 34x16 with a very interesting profile.

If you count them all, this sentence has exactly seventy-two characters.
Glad I bookmarked this thread! Are you keeping this one in your garage? And are you doing the engine stuff yourself? I honestly don't know if what you're doing is complicated or not, or if you have a background in it.

gently caress I miss flying. I got my PPL through cadets like you did, and I haven't flown since my flight test twelve years ago. I swore I wasn't going to be one of those guys who just gets it and never uses it again, but life and money got in the way as I guess it does.

The plan is to do all the work in my Garage and basement workshop. I've worked on small engines before and have helped out on a few homebuilt projects.

Don't feel bad about the path that you took after cadets. It is a program that doesn't really set you up for success as a PPL. Most kids who get a scholarship are immediately into college and broke. Many are so far removed that they feel they cannot get back in but it comes back.

It comes back fast. Go up with someone else or an instructor and you will be surprised at how quickly you get the skills back.

If certified aircraft are to much money there are always gliders to fly. I'm taking a bunch of power pilots to a glider field tomorrow so they can get some experience.

I ran into a guy at Oshkosh who was in my flying scholarship group. He flys the #10 Snowbird.

Hah, awesome. I know two of the Snowbirds from Cadets as well (#2/6).

I'm attempting to get flying again; the hardest part I think will be getting familiar with the regs and procedures, more so than the stick and rudder skills.
