willem I did not use carbon for the landing gear,but went straight to using spring wire from the start. I bent so as to fit onto a bit of thin ply wood and cotton stitched the wire on and CA glued . I then glued the ply onto the flat body part and put a recess in the lower vertical depron so as to fit around the ply. Photo shows all .
keep posted on your new gyro......cheers Graeme

the last photo should say forward looking rear.

out again this evening just before dark.A bit of a breeze but still flew good.
So far this week have had 8 flights.
Finally got someone to take a few pics and movies of the gyro.

Had a few more flight with the gyro......A bit dissappointed there are not a few others building this model. It is absolute fun to fly around and always creates interest when ever anybody sees it.Seems the thread has gone dead..I am now into building something else so will be signing out of this thread . cheers

Hang in there mintie. I'm building one here in Alabama, just making slow progress due to a brutal work schedule. I've been watching this thread hoping for more activity myself. Mine will be running a 1500 kv Blue Wonder on a 610 3S since I use the same stuff on a Firefly and a Yak. Let's keep this one going.

Work load is finally easing a bit so I may get back to building one of these. Anybody care to post some close ups of the rotor hub? Thanks

It works - thanks for the plan


I'm new here in this forum.
The plan and the help from the forum emtries itself give me the chance to build this Gyro. It flys since three days.
I only modified the rotor itself by adding two mini ball bearings (2mm) and use some 2mm Polystyrol plates instead of the Depron circle parts for the 120 Rotor ((after the first crash (due to slow rotor rpm at start phase) the Depron was broken). With that small mod the rotors free movement is much better and the rotor is much more stable during flight.
In addition I mixed up some percent of roll to the right based on the engine speed setting (I had some problems before: I have to roll a lot to the right if the engine speed was set in the above last quarter). With this mix it is much easier for me to fly.

I just found this thread through this video on youtube. Great video, I never thought that a gyrocopter could do the things it does in some of your videos!! (quick loops and rools, hover, high alfa) nice job! And it sounded really windy, for a 6-7 oz craft it did amazingly well with the wind. Just what I'm looking for, a great indoor AND outdoor flyer. I have been doing helis and 3d planes for a couple years now and love it. Now I will be putting one of these ( and a Mr Twister) in my hangar. Lets keep this thread going. Will post pics of my build as soon as I get going on it.
Again thanks fo the great video that brought me here.

Did you check out Gary's (SR71fan) mini piyak or dark pi stealth vidoes? Excellent as well and can be found in the scratchbuilt forum. Link to Gary's vids on youtube.

AG3 with skies


due to the lot of snow in Bavaria I modified the AG3 by using some simple depron skis instead of wheels.
It works - the ski could be a little bit bigger because starting from loose snow they grab a little bit into it.
Problem are the humps in the snow - the AG3 then often create a kind of headstand but in general it works better to start from a snown street with the ski instead of the whees.

Next think I want to try is the use of a two blade rotor...

try plastic whiffle golf balls instead of skis, they go across the snow great, ussually even the powder. they look cool too throwing up snow as happily roll across the top of the snow.
