Beautiful, but that Rotec engine??? Verner would be perfect.

J'adore cette machine. Superbe et peu connue. Merci pour la vidéo, c'est rare de voir le modèle en vol.

That little door looks like a great idea. It looks nice and from the looks of it aids in getting aboard much easier. Great idea.

Where is this?? Nice!

Looks like a beautiful grass strip. Really appreciate the guys who take time to keep those places in such good shape.

How's that engine holding up? I've heard about a lot of failures with them

What's the engine ?

Hopefully I’ll get the chance to arrange something like this for my time building! 🤞🏻

How capable are these for basic aerobatics? It’s not really what they are designed for, is it?

The person who covered this airplane does first class work. Just watched and appreciated how tight the covering is.

Hou old you pláne

I would love to build a plane just like yours! Where did you get the Kit and what kind of radial engine did you use. Cheers!!

What a beautiful plane! What variation of the Hatz is this? Where can I get the kit? Also, is the engine separate? I love the radial engine. Would love to find out more of your build.

Are any of the two seated Hatz in the USA Light Sport cat?

awesome

nice old girl!

Watch the propeller strobing furiously-either the camera can't keep up with the revolutions, or our eyes/brain can't. Which one is it?

beautiful Jr Ace and lovely sound of the Rotex radial. Airframe and engine seem to go well with each other cosmetic and power wise. Thanks for posting so long ago.

Did anyone else think "oh crap" around 5:28? lol...

I could look at HB-YSH all day long. Gorgeous build.

Fantastic! This is my dream airplane. I hope to start building one within the next few years. Same setup with the Rotec.

Wow, super. Halwilersee? Gruess Thomas

So geil ey! Schön dech gseh flüge i dim Kunstwärch, sehr geil, wow!! Ha jo persönlech mitübercho wie intensiv das esch :) freu mir enorm för di!

What a terrific plane and view. Congratulations on your very successful first flight. Don.

Best-looking Hatz I've ever seen and maybe homebuilt biplane trophy also! Exceptional!

what's the dry and built-up weight of this engine?; of the 150 h.p. engine?

Very well done! Should you happen to land 100km to the north of Cologne one day, you're welcome to drop in and have a look at my DH60 project!

Excellent! Very nice to see! Congratulations! As a small suggestion, I would recommend a hard helmet on a first-flight, and probably also for the working-in period. But it's a lovely airplane in a lovely place!

Pity we never got to see it fly...such a lovely looking aeroplane. Congratulations.

The best home built ever made in the history of experimental aviation. PERFECTION!!!!!!

Great looking plane, love the sound! Thanks for posting.

Guy's it just doesn't get any prettier than that. Absolutely beautiful! Can't wait to see the first flight.

Congratulations Hans, this is a wonderful authentic biplane ! Benoit (with your flying wires :-)

Lovely Guys, Two Thumbs Up ! !

Looks and sounds great guys. Absolute craftsmanship. I would love to see the finished product up close someday.

This it the ninth video I've watched and STILL no real engine, always the stupid Wright. Is everyone such a cheapskate they can't afford a real engine?

How much weight did you put on?? Did you use the wings in the plane later or only was for testing?? Nice plane!! :)

love the plane, love the engine

How lovely. I still own a helmet and goggles because I REALLY want to do that again at some point.

Has this plane flown yet??? I've seen it at Sun-n-Fun but never seen it in the air.

nice lookin' airplane... radials do that I guess

Ah, very nice.

I know I am wrong but the engine did not sound too good, as though it was missing a little. My father (ex RAF) used to have the tech manual for the engine on this bird, sad to say, it got burnt in his factory after some local scum tourched the place..

It sounds like an old Hot Rod! I love it!

What a delight to see this aircraft. Bud Willson was my dad and he and Chuck rebuilt the wings on this aircraft in our basement. I still have the original prop that was damaged when Commander Downey made an emergency landing in the Morton Arbouretum. Great to see the ol' meyers is going strong.

R2800 as seen here is the cheapest bang for buck around $15K usd gets you going! No Rotax 912 can match the price or smile factor! Rotec Australia bends over backwards to keep you happy!

I am SO JEALOUS!!! Tim's Jr. Ace turned out to be BETTER THAN SEX!!!! GREAT JOB!!! I followed Tim's building this as he posted photos as he was building.

How much of a hole in your wallet did that engine put in your pocket? I've always wondered how much they cost and haven't seen any reliable price from Rotec.

This plane is painted to reflect Korean War operations while in service with the Royal Navy.

Yes I have one of these in my homebuilt, 450hrs havent touched it yet. Excellent performance and draws crowds where ever I go. The factory support is good and parts are cheap compared to most others. Most servicable items are off the shelf Automotive filters, plugs, ignition etc. I read that there are now over 500 sold in the USA.
