Had the pleasure of meeting and hanging out with Mark in Mojave in 2009 if I recall the year correctly. You are right. He is opinionated. If there is anyone that is allowed an opinion, it is Mark. He is a gentleman and very gracious. If there is only one person to get their opinion on a Cozy issue, I would pick Mark. There are many others to trust as well.
@@zeitlinm I was wondering, since in this case it was a fairly short runway. BTW my VariEze is based at KLVK and we've chatted a few times (and you gave me ride in your airplane when Fred L. and I were thinking about getting a Cozy). Happy travels on your summer tour!
@@CanardBoulevard you think that would equate how compaired to yours landing?? hard landing? WOULD IT WORK BETTER ON YOUR ORIGINAL AIRSTRIP than your bouncy bouncier one??? for an exanple that plopped into my head just then... benifits? pros? cons? have ya thu8nk about them much?
Scott: Did you by chance follow the Raptor Canard development about 3 years ago? I really wanted that design to succeed, but the Audi diesel engine was not up to the task for such a big heavy airplane. I believe Mark was consulted about the design. th-cam.com/video/5gnEknj242M/w-d-xo.htmlsi=BATWHMwiDlSkBbjR
I did...and could tell that it was doomed to failure. He was just too stubborn, and refused to listen to those who had expertise and experience. I'm just glad nobody was hurt when the inevitable crash occurred.
Landing on grass is usually frowned upon because the wheel kicks loads of dirt and grass up into the propeller. Folks who’ve operated a Rutan canard out of (suitably firm for the small nose wheel) grass fields have had to refurbish and replace props regularly. No suspension improvement will fix that.
So this is an interesting question. While the nose gear can kick up FOD into the prop, and that is problematic, it's NOT the major reason that soft/grass fields are contraindicated for these canard aircraft. There are really two reasons - first, the wheels/tires are relatively small (5.00x5 on the mains, 10-350x4 on the nose) and inflated to high pressures, so any bumps, potholes, divots or high grass can cause damage to the gear and/or wheelpants. But even more critical is the geometry of the nose gear, particularly when there's a spring cartridge in the mechanism (as there is on >95% of the VE, LE and COZY canard aircraft). Due to the angle of the gear, if there's a large aftwards force on the nose gear due to soft ground and/or high grass, the nose gear will tend to deflect upwards, which will lower the angle of incidence of the canard. If this happens to a large enough extent, no amount of elevator deflection will be enough to allow for rotation on takeoff. Now, without the spring cartridge, this gear deflection will be substantially reduced, so MAYBE the EGP nose gear system will make it more likely to be successful on soft/grass fields. But I won't be the first person to test that 🙂.
Thanks for the plug, Scott! 🙂
That's cool you got to meet Mark! I love reading his replies on the email thread! His sarcasm is top notch! I kinda miss his WTFIGOH game.
It was cool to watch Marc flying in to your airport. He's a good guy, did the pre-buy and C.I.s on my L-EZ.

Marc is great. Love the knowledge and transparency.
What an honor!
flying your Cozy must be fun, but 1:50 wow it's hard to beat that view.
Thanks for the quick video. Would love an interview with him, if you get time again.
There are quite a few videos of him on TH-cam doing presentations...but not enough time for an interview on this visit.
Awesome information thanks 😊
The Cozy IV doesn't have a belly board speed brake? I assumed it would, like the Long-EZ and VariEze (which I fly).
It does - I just didn't use it on that landing (I do on 90% of my landings) for reasons that I don't recall at the moment.
It does!

too bad you couldn't ride along and get an idea of the front end mod/work eh? AWESOME SHORTY VID :)
I did push/bounce the front end while it was on the ground. It's significantly stiffer, and the bounce is much less.

does he have a youtube channel ?
No.
Yes. @zeitlinm although there's not a whole lot on it - just a few presentations and a flutter video.

Considering the wealth of knowledge that Mark is in this niche topic, has anyone compiled his working knowledge for formal preservation?
I'm not dead ... yet... 🙂.

Does his front gear mod allow him to land on grass?

- Cool.
Love the wrenching videos and flying tips. I watched hoping for some insight on the Cozy but 4 min of nothing.
