I think I'll try the toothpick mod. Are you using them on the inner hole or utter hole?

I am using them on the inner hole. I found that after about the fourth or fifth flight, they start to get loose. I remove them at the end of the day anyway for transportation so new ones go in at the beginning of each session.

The wind was getting gusty by mid afternoon and I would hold station on the runway with the prop till the rotors were nearly up to speed and then add a few clicks of throttle to start a takeoff roll and the AG JUST LIFTED OFF. NONE of my takeoff have taken more than 50' to get airborne. All in all, a very good day with autogyros!

Still waiting for parts but I can't wait to get her airborne!!

Definitely not enough rotor blade speed & "rushing" her to get in the air, although i thought the blades were spinning fast enough?? First gyro, will for sure hand launch (I'm sure it'll be a running hand launch, LOL) when the parts arrive, looking forward to seeing your pics of the two gyros cruising by!!

With your takeoffs no more than 50' was the wind blowing steady? If so do you recall the wind speed?

Thanks Sam for posting these! There's always more than one way to skin a cat

I'm not totally done with the graphics yet. I'll be filling in the rest of the body and fins with yellow and black stripes.

The wire gear is stock but I put on some 2.5" wheels. I feel like this helps with spinup since the elevator is useless until it is in the air. At about 1/2-3/4 rotor speed I'll actually feed in a touch of down and a hair of right aileron. I know this doesn't sound very scientific but it's more about "feel" than any. As airspeed picks up, the tail will start to lift and I know that's when I'm flying (and be on my toes for what it will do next)

The wind was pretty steady at about 6-7 mph. It was actually perfect for ROG. If there was absolutely no wind, then you might have to jog. The average person can fast walk at about 3 mph and that's enough to get the rotors up to speed for hand launching.

The LEDs on the lower side of the body are very bright white ones. They light up the runway when they get close to the ground. There are blue ones under each horizontal stab and I have a removable carbon fiber tube that mounts accross the front of the pylon. I have red lights on the left and green on the right attached to the tube that shine straight up at the rotor. Makes for an interesting display on the rotor as it spins! Half the disc is red and the other is ...well, you know, green!

Tried my maiden this morning. No wind and I just couldn't get enough head speed to get off the ground. It tipped over and over on its side before it would spin up. Any suggestions? I guess I will just have to wait for a good breezy day. I tried jogging a bit but still couldnt get the headspeed up.

Ouch! I ran out of some supplies and then, while I was waiting for them, I got sidetracked with other projects. It's still in the queue, just a little farther down.

Stearable tail wheel

OK. This is what I have so far.
I removed the rudder from the fin, the control horn and lower hinge pin from the rudder. The hinge pin is glued in well but can be worked loose without damage.
I sliced the rudder from the bottom about 1/32" - 1/16" in from the skin up to the top edge of the horn recess.
I glued in 2 hard balsa pieces to the sides of the cutout. I then added another piece of balsa between the first 2 pieces. This extends from the top edge of the horn recess to the top edge where the hinge pin will go back in. I glued in a thin spacer where the bottom edge of the hinge pin will go back in, forming a pocket for the pin.
A piece for 3/32" brass tube was fitted and glued in. Make sure that it is 90 degrees to the hinge line.
A piece of 1/16" music wire was bent to have a leg to go into the tube in the rudder. The wire will be bent to fit the wheel, after it is inserted in the brass bearing tube.
Another brass tube was cut to act as the bearing for the music wire.
A piece of dowel was cut to fit closely inside the tail boom. A hole was drilled at a 17 degree angle into the dowel for the brass tube. The brass tube is then glued into the dowel. Trim after gluing to the dowel. A few wraps of kevlar thread were added to help keep the dowel from splitting. The dowel will be held in place with with a screw through the boom.
If there is damage, the install can be removed. The wire leg is not glued to the rudder. Take the dowel retaining screw out and the tail can be removed. The rudder can be removed and that allows the tail wheel assembly to be removed. You can replace whatever parts you need to and not have to do the whole tail wheel assembly again.

Btw,i'd lve to see your steerable tailwheel mod,Ken Lilja,please.
Pretty please.Very pretty please
