Finally, I bought my first gyro.

The gyro I acquired is the same model as the one in this picture.

Not CLT. No HS. I plan to improve on stability as soon as possible.

Congrats, looks like a neat gyro. what is it powered with and what kind of rotors etc???

Please don't risk yourself or your machine. Put a real big stab on it before trying to fly it.

Jucie,

I looks good. I look forward to hearing more about it.

Ron, the engine is an air cooled VW 2100cc. Here we have some skilled workman able to build blades. Unfortunately, I don't know who made the blades on my gyro. A skilled pilot friend of mine tell me the blades works very well.

Altair Coelho, a brazilian aeronautical enginer, conceived this project 25 years ago. More than a hundred copies were built. None of those has horizontal stabilizer! The veterans say it doesn't need one, but I know it will fly much better with a properly designed tail. So, I plan to build one myself.

Todd, I live at São Paulo (the fourth biggest city in the world, where gyro flying is absolutely forbidden due to demographical density). The hangar is as far as 80 km (50 miles) from my home. As soon as possible I will take some pictures and post here. Maybe this weekend I won't because I will be very busy taking lessons with an certified flight instructor (even farther - 200 km).

Thank you for the interest.

No gyro needs a stab to fly, but show me any design gyro that has not or will not PIO or PPO without a stab? that is what you tell your friends.

A Raf 2000 can be flown all day long without a stab but there has been many bunt overs due to that. But the flip side is there have been zillions of flights that have made it back safe without one. So it is true you don't need one. But.... Your in a safer machine if it there is one installed.

The 2100 Vw should be a lot of power for that machine!

I am glad Jucie is in both Forums, I don't know if I had anything to do with it, but I have been beating the drum for safety down there in our ABGiro Forum.
He seems to understand and wants to follow the right path and I am very pleased.
I like the AC4 very much and will try checking the measures soon and get the bandaids for it.
There is a cheap source for begginners gyro!
Interaction, elightment and solutions, this is what this forums are good for!!
Thanks

Heron, of course you have A LOT to do with my vision about gyros. You did the first post about gyro stability issues at our brazilian forum, do you remember?

Thank you very much. I say it on behalf of everybody at that forum.

[Heron]

Just passing the torch Jucie . . .
I got it from NOrms Forum and if we go on, in time everyone will have at least some light.
see you soon
Heron

Several people asked for details about the gyro, so that is what I got:

AC-4 is the fourth project from Altair Coelho, a brazilian aeronautical enginner. It's an evolution of a previous gyro, the AC-1, and the first flight happened in 1964. As far as the designer keeps track, 314 units were built, by 2 brazilian licensed manufacturers.

Rate of Climb: 10 foot per second
Empty weight: 157 kg (345 pounds)
Max. weight on take-off: 290 kg (638 pounds)
Blade profile: H-12M
Rotor Length: 7,60 m (25 foot)
Engine: air cooled VW 2200cc
Power: 85 hp
