The first UK autogyro meet was held at Winterton MFC in N. Lincs earlier this year. Wind was a bit strong and I only brought foamies, but here we all are (all 6 of us!).

Just read Al's blog (Rotorheid) http://www.rcgroups.com/forums/member.php?u=98579
That Alogallo (Gymallo) looked great so have to have one! As I have 1/4 inch spruce to hand, I decided to scale it up by a factor of 1.333. This is a fast build!

Bought some ripstop kite fabric and repair tape from a local hobby shop, and soon found out that stuff is not easy to stick! It resists most adhesives, but I eventually found that PU liquid glue works best, although it foams on curing so there is always a slight overspill.

Pics and maiden flight video to follow.

Update 12 July 2009
My Alogallo has now a 10 * 4.5 prop on and wheels have been enlarged by sticking rubber doughnuts around the existing tyres.
The difference in performance is tremendous. Full power at takeoff will now cause the model to take off, climb steeply and eventually loop with no elevator input!

Alogallo (6 min 17 sec)


Update 16/7/2009
My Alogallo now has a mini partner, 75% of the original Alogallo plan. I built it for indoor use. Wing area 1 sq ft. weight 110 grams all up. Unflown as yet.

The maxi camera kite is yet to come!

Not used to writing a blog, so don't really know where to start. I'll just ramble on and hope you find it entertaining.

I returned to RC flight after a break of over 20 years. I learnt on mode 1 and the pressure to change to mode 2 was great. I resisted it because I felt that the thumbs were still programmed mode 1 even after the long layoff.

My main interest is anything unusual, and autogyros in particular. As I type this I have almost completed my RPG autogyro. Many thanks for the guys on the Autogyros forum who give help and advice freely, and Rich Harris in particular for supplying me with RPG plans before general release.

Regards all,
John

Update...
I have now discovered the hard way that the blade profiles shown here are NOT the way to do it. They look OK but require thick shims to make them autorotate. The right way is to have a totally flat bottom all the way to the LE. - Live & learn.
