ag3-2l sorta

i am so excited i finally bit the bullet and bought some 3mm midwest cell foam today and built a cross set of blades,kinda from what i started and s71fans design for my leadfeather's apache i could never get air born, but it was already dark out for test flight but it lifted off after about 50ft running down my drive way.at last i have never seen that before and can't wait for Friday evening to get here

Luke,

I enjoyed the video (and music)! Thanks for posting.

Deisel1,

Congratulations! Glad to hear that it flies.

Gary

I too had a chance to do some more flying with my AG3. Winds still terribly unpredictable, and very turbulent. But, as I know by now, no problem for the little gyro! Flying buddy DirkIII made the small video for me.

Happy Easter everybody!

Willem

Luke and Deisel, nice to read that your AG3's fly too. But, really, what else to expect from such a wonderful design? I have been playing with r/c autogyro's for many years now, some came out being more succesful than others, but Gary's AG3 has been by far the most predictable and succesful autogyro to date!

finally started

I spent a couple of hrs tonight and got all the bits cut out. Tower and elevator glued on ... need to get a bit more carbon rod and some larger wheels...have all the rest .will try and get finished between other projects.
Going by other posts this is going to be a bit of fun.
My rego will be ZK SAG [simple auto gyro]

I noticed I have to give quite a bit of 'up' elevator on my AG3 while turning. Rather than mixing this in on my Tx, I thought I'd slant down the rotor head hinge line. This way, as the head tilts sideways, it also tilts back somewhat, effectively giving 'up' on the rotor disk. Look at it like a delta hinge, like on some rotor blades...
Does this make any sense to you guys?

Also, I'd like to show how I measure the hang angle. The rotor shaft line is drawn on the fuselage. You can barely see it in the picture. I stick a toothpick or a pin right below the rotor shaft. The thread with the weight shows me the approximate angle when I hold the gyro at the end of the rotor shaft...

question..on the plan it shows 2 mm carbon rod taped to the rotor blade leading edges.
I have some 3x.05mm flat carbon, would that be useable and have enough flex to allow the blades to cone when in flight, or perhaps be a bit stiff. cheers.

Any word on the effectiveness of your hinge idea yet? Looks to be a sound method to me. Nice work.

Mintie,

have you thought of cutting a slot in the LE of your rotor blade, then push the flat carbon in? I wouldn't even glue it, just tape it. Your blades would be about a foot or so, so I can't see much of a problem with over flexing.
Just make sure that for the maiden flight your rotor head is slightly tilted to the right (on electric gyros we always fight the propeller torc, not the rotor torc!)
Like Gary said, the tip of the rotor shaft should be in the centerline of the rotor mast on this one. Also, keep your rotor tilt very small: 1/4" to each side is more than enough. Even then, give it some 60-70% expo. Rudder also 60% expo if you like, withe 3/4" each way. Elevator as much as you can get up, down till you hit the floor. It also helps if you mix in some rudder with rotor tilt (=aileron)
Good luck!

Boneswamped,

Lots of work last week, so the building on the AG4 has stopped for a few days. As soon as the maiden flight has been done, I'll report.

Boneswamped,

By the way, your profile Kellett is SO cool! I have started on a depron version, keeping Gary's AG3 principles as a guide... Ofcourse, there will be rotor tilt fore and aft too.
I'll keep you informed!
