Hi Chris,

An impressive kit of parts, and all coming together making a very nice build of it. I'm sure your posts will help many of those new to to gyros, and to some of us which aren't so new yes

Cheers mate.

There is one other small mod that I made to this build. I thought that a little more rudder may be handy...so I went with linking up the two outer fins as Rich did with the big blue bird.

Happy Landings

Hi can anyone advise on why the rotors are not spinning up enough .First flight was lucky to get into the air but trimmed and flew well.On next attempt could not get enough speed in rotors.

Hi Brian,

Difficult to say from the little you have told us, could be blade profile, head rear tilt on take off run, speed or blade weight/ negative incidence.....

Any more info like shim thickness, blade weight, pic of profile etc would help suggestions....

Thanks Steve for your quick reply blade profile and incidence are as plan the rotors don't seem to spin up when pointing into wind very fast and was wondering if more negative incidence would help.There is 5 degree of tilt on the head when tailplane is level

More shim and negative will increase spin up but there is a trade as it will kill lift, head at 5 could be OK , more back tilt will help but affect trim. Set hand angle as plan approx 16 degrees then do the test hops to trim head angle. If plenty of lift from blades you could consider a little more shim.If you do just watch for the reduction in lift...

This is the fun part of autos , trimming needs adjustment of several things to get that sweet spot..... Maybe that's why many try and struggle to start .... Great fun and rewarding tho .......

I had the pleasure of meeting Brian today at his field, considering that this was his first ever plan built model and heat shrink covering job he has made a fantastic job of his Cruiser. Infact, I was embarrassed to get mine out of the boot of my car embarrassed

We soon had the model in the air with very little trim correction needed, the blades spun up without a problem. Using the technique Steve Jones explained they were whistling within a few feet.

I passed the transmitter to Brians 'mode 1' clubmate Barry who carried on with the flight, I managed to snap a couple of shots but the light wasn't very good. The model had several flights during the afternoon until the light faded where we moved into the club hut for a cuppa.

A good afternoons worth of flying and a big thanks from me for the invite thumbs up

No excuses now not to come along to our autogyro fly-ins now wink 2
