RC electric Kyushu J7W1 Shiden

[sedonakevin]

Hi everyone,
I recently aquired a set of plans from Diel Engineering/Dare Designs for a 1/24 scale rubber powered Kyushu J7W1 Shiden, a WWII Japanese canard fighter. I would like to scale up the plans to 1/12-1/10 and maybe build an electric version. I have two basic design questions for the experts out there.
First, since the twin rudders are placed on the (large) winglets, does anyone have any ideas about the mechanics of getting them to move? Could I use a pull-pull system with the 2 servos installed in the wings? Any better ideas?
Second, does anyone know of a source for a 6 blade pusher prop? I could always use a 2 or 3 blade pusher prop for flight, but I have a real thing for exact accuracy. OK, OK so maybe I'm a rivet counter.
Anyway, any help would be greatly appreciated.
Thanks to all for any help.

Sounds like a great project for electric sedonakevin, good luck with the model! As for the twin rudders, it should be a simple matter of using a single servo in the center of the fuselage and run thin flexible throttle cable inside Nyrod tubes to control both rudders with clevises and control horns. As for a 6-blade prop, I don't think there are any commercially available. You could graft two 3-blade props together by notching the center hubs so they key together, but this would be only for static looks, not for flying! But who knows maybe there is someone out there who can make them!

I have been working on this same model off and on for a few years. The rudders and alerons use sullivan flexiable pushrods, the red ones. both are currently set up as central wing mounted servos. the main problem I have is connecting the front wheel to the wing mounted rudder servo. I finally gave up an installed a micro servo to turn the front wheel. I am currently setting it up with a .25 2 cycle, but thats subject to change to a brushless lipo system. The electric system is a lot cleaner to use and should weigh about the same. I enlarged the 24 inch rubber powered plans to 36 inch wingspan and went from their. Hopefully I dont have it to heavy to fly, but it still will look cool taxing on the ground if all else fails.
