Hollmann HA-2 Sportster Gyroplane

Hi Everyone,

Can someone help provide me with the empty weight and gross weight of Martin Hollmann's HA-2 Sportster Gyroplane? I'm curious in comparison to the Sparrowhawk.

Thanks

Wayne

Hi Wayne

Here is a copy of the Hollmann HA-2 Gyroplane from June 1980 copy of "The Encyclopedia of Hombuilt Aircraft".

The 1st 3 pgs were to big for the file but I can email them to you if you like.

Hope this helps.

Alex & Jon,

Thanks guys for your help.

It is interesting to see that the Hollmann HA-2 Sportster Gyroplane can be operated under Sport Pilot rules because it's gross weight is less than 1320 lb.

I've always liked the look of the HA-2 Sportster, even though it is a HTL gyro. With the center of gravity point some 6 inches below the center of thrust, and the horizontal stabilizer well below the propeller arc and low on the airframe, I'd be hesitant to fly one. I did see Martin Hollman's Sportster N158 at Chino some 20 years ago, however I never have seen it fly.

I know there are three HA-2 Sportsters built in Sweden and flown. I would like to find out how many HA-2 Sportsters are flying in the USA? If any, I would like to read comments how it flies by those builders themselves.

As I understand it, Martin Hollmann has not flown his HA-2 Sportster much over the past 20 years or so, devoting more of his time on developement and sales of his Stallion airplane.

The only other time I have seen a HA-2 Sportster was at El Mirage in 2000. The Gyro didn't fly while I was there and it didn't even have an "N" number registration on it. Does anyone know if that Sportster has since flown?

Thanks everyone!

I have an Old EAA mag with a write up about it in it, I will read the story on it and let ya know what it says.

Hi Animal,

Could you by chance scan that old EAA article and e-mail it to me or post it on this form please?

Thanks

Hi Teddy,

The pictures of the HA-2 Sportster I took at El Mirage belong to you? If so, where do you keep it at?

I'm not surprised to read that with the Hollmann Blades, there was a bad stick shake. I've read comments in other threads within this forum from other people who flew with Martin Hollmann in his Sportster saying that his gyro had a pronounced stick shake too.

That big flat area on the wind screen must cause a fair amount of drag. I wonder if the wind screen were to be curved in a half spherical shape, the drag would be some what reduced? I can only imagine that alot of drag is created by the aft cockpit bulkhead/firewall being as flat as it is too. All of the Swedish built Sportsters have faired cowlings behind the cockpit and around the engine. I wonder how their Sportsters fly?

It is a shame that it appears the Sportster does not perform as well as expected.

The first picture is interesting. In addition to the Sportster almost all of the gyros in the picture were HTL -one Air Command Low Rider and four Bandits. The gyro on the extreme left was a true CLT - with a large Horiz Stab fully imersed in the prop stream --and it recieved "Best New Design " award. In fact I have that Plaque hanging on my wall!

Does anyone know if there are drawings available for the Glanville Skymaster modifications for the Sportster? I understand that the fuel tank was mounted on the front of the firewall, just behind the seats. I am also interested in performance specifications for this modification, as I have a set of Sportster plans that I would like to use to build the Glanville Skymaster version.
