Just ordered an Auto-G over the weekend. I have been a fan of these type of aircraft for years but this will be my first. Always had an issue with how ugly some autos can be. Not that this bird is gorgious or anything!

I'm excited to get my hand on get a little stick time. Might have to wait till July to fly the darn thing the way there weather is around here...

Anyhow, I was thinking that I might swap in a single, more powerful servo for the tilt. I have some laying around so why not. Will the arm on the head need to be reinforced if using a single servo?

Why mess with it if it works just fine? Learn how to fly them, then start modifying. Good luck!

You make a fine point. You know how it is... I can never seem to get a plane into the sky in stock form. I always seem to tinker and tune with designs.

I believe the left side of the rotor disk stalled. Same thing happened to me at low speed. Notice the pitch up and then the roll into the ground. Same thing happened to me. Right aileron had no effect during the stall. Much like taking off without enough rotor speed. You can hold full right aileron and still roll left.

Well, my buddy hooked me up and made the Rotor Blade Grip out of 1mm styrene from the LHS, he ended up doubling it so it's actually 2mm thick, we're all set to go for our 1st true "maiden" but it'll have to wait 'til after the holidays, but at least I'll be ready!

I think I'll still give her a go with a ROG takeoff, since the wind is calm when I fly I don't mind driving her around a bit 'til those rotors spin fast enough to get her airborne.

Happy holidays & report back soon

Plastic from a Tide bottle is very flexible. That is the old school way. Styrene may snap from the flapping of the rotors.

Just thought....

Awe man..... I did think 'bout a Downy bottle?!?

I'll let you know, sounds like that Tupperware top is the way to go??

We'll see, hope it works, received her when she first came out, my 1st gyro, & have yet to fly her, LOL

The rotors need to stay at the a high rpm so they create the lift you need so it does not roll left.

As the rotor turns CCwise, over the nose the rotor lifts and the blade drops as it passes the nose. As the rotor spin by the tail and up towards the nose again....all lift is to the right side if rotors are going too slow. If the rotors are going too slow, there is no lift to the left side produce asymmetry of lift or it tilts to the left side.....uing right aileron only compounds the problem.

The rotors ARE your wing. Just a an old WW1 monoplane will roll to one side if too much throttle is applied before proper lift is achieved is also applied to your rule of thumb with the autogyro. Start off slow....wait for the rotors to spin fast, with slow and deliberate increase of the throttle....it will lift off without use of elevator. Accelerator make you climb. Use rudder to turn. compensate how it leans with aileron.

The rotors must be spinning at it's highest rpm to create lift. Pulling back on the elevator is making you stall or flare out. That is what we do to land with a no roll out. We get close to the ground....kill the motor and pull back so it noses up and autorotates down to a no roll out.

Here is one of my movies with one of my gyros and I explain what I am doing....I had to set it up/trim it out first....you can watch all that or go to 4:40

rcoconut,

I'm not sure what part your friend has made from styrene but if it is the Y-shaped piece that the blades are bolted to then, like Dave, I think the styrene will be too brittle and it would probably break.

Hope this helps,I'd hate for you to lose your Auto-G to a brittle part.
