Serus ciervapilot and all the autogyro nuts,
there is a model of the rotodyne, excluding Don's, that flew but as a helicopter. The model was built and flown by Jim Morley, an Englishman, now in retirement, who had a company producing model helicopters.
DETAILS TO THE MODEL.
Using his words the model had:
a wingspan of just over 3 feet (>.878 m),
a length just under 4 feet (<1.171 m), this makes the model approx. 1/15 scale
a rotor dia. of 5 feet (1.524 m) and
a weight of 14 lbs (6.36 kilos).
The chassis, mechanics and rotor head originated from the Maverick helicopter (produced by his company).
Engine was an OS 61. (Only one engine was used)
Rotor head was standard Maverick with conventional helicopter functions.
Secondary shafts were connected, under the wings, between a clutch and Maverick tailrotor gearboxes mounted in the engine nacelles.
To overcome the torque the props, both rotating in the same direction, worked in a push - pull mode. The port airscrew, with negative pitch blades, pushed and the starboard airscrew, with positive pitch, pulled.
Each airscrew was constructed from Maverick tailrotor components and had variable pitch blades. A special boss was turned from alu to accept four blades.
One servo (for the airscrews) provided pos./neg. pitch for one airscrew and a reverse function neg./pos. pitch for the other. This simulates the function of a tailrotor.
A second servo provided pos./neg. to both airscrews, this allowed forward flight or taxiing. Each airscrew was a mini rotor head.
A video of this model "A Fairey Rotodyne Story" is available (VHS, no DVD and PAL only) from [link=https://sslrelay.com/s84068217.oneandoneshop.co.uk/sess/utn;jsessionid=1543b56075ad1ba/shopdata/index.shopscript]Traplet Publications[/link] the price is 9.95 BRP (without postage).
I have spoken with Jim Morley with the hope that he still has plans available. At the moment he is searching his hobby room and garage. Should they turn up I'll leave a message on the forum.
Now that you have the info I'll be back tomorrow to look at the finished models

.
Oh by the way I'm planning a model of the Rotodyne as well, with heli liftoff and autogyro flight but full electric and I'm looking for someone to help me with a prototype mixer. Any volunteers? [sm=drowning.gif]
P.S. I have a lot of photos, simple plans, drawings, cutaways etc. but I cant find out how to upload them.
P.P.S. Don Incoll has given up modelling sold all of his models and equipment and wishes to remain incognito. This is a great loss to the modelling world as he produced some fantastic and very original models. Please respect his wishes.
MfG, best regards, Karl.
