Hi there,

I'm the designer of the Twirl, and I've just happened on this thread, so I'm realy pleased to see some of you building it in the USA

I've recently modified the Twirl to a single rotor configuration using the same fuselage and a centre pylon.

There is a thread in one of the UK forums with a few details and a couple of low quality movies of the Monotwirl (as I've called it), as well as one of the 2 prototype Twirls.

Here is the link :-

http://www.rcmf.co.uk/4um/index.php?topic=26384.0

BTW, I have flown mine indoors with no problems at all, even in a single basket ball court-sized space - you just need to keep it turning, or else pull the nose up and fly it slow .

I've also got a couple of other designs here:-

Go to the features page for flying models of Fireball XL5 and Thunderbird 1.

Enjoy

Al,
Thanks for signing on to this thread.
I still have to install the radio in the Twirl I am building. So far the build has effortless with no worries. I can't wait to fly it.
If you have time please post us a picture or to of the rotor head you are using on the mono-twirl. Concurent with the Twirl build I am also building a depron single rotor gyro and am always looking for ideas. Thanks.

Hi again,

Here's a couple of shots showing the single rotor pivot. It is basically a 4mm OD carbon tube rotating in a 6mm ID tube, the latter being glued to the top of the centre pylon with epoxy. The control horn at the rear retains the rotating tube at the back, and the short 2mm carbon rod rotor shaft and its rotor bush retain it at the front. The rotor is articulated in roll only, with rudder and elevator controls exactly as per the original Twirl design.

The rotor blades are the same chord as those of Twirl, but are 11 inches long, and now have a 3mm by 3mm spruce leading edge (the paper spar as used on Twirl was just TOO flexible). This gave almost the same swept area as the 2 smaller rotors.

The blades have slightly more negative pitch - I did this by adding 1/16 balsa plates to the bottom of the trailing edge of the blades at the overlap points, and adding a square of 1/16 balsa to the original Twirl balsa hub.

The rotor is tilted back 5 degrees, but I think it could do to be about 8 degrees. Maybe on the next one........

Hope this helps.

Al Foot
