Dave Platt Executor

Just started cutting out some parts for a 1963 Dave Platt design "Executor" originally spanning 54" for a .15 cu in. engine.
Intended for Single Channel using three rubber driven escapements - plan from Outerzone
https://outerzone.co.uk/plan_details.asp?ID=9919
I liked the overall shape of the model as well as the symmetrical airfoil which I think should handle a breeze better than a flat bottom.
That and the fact that Dave Platt is known for some pretty good model designs.
I have scaled it down to 80% size to suit my Enya .09 that I will be using. (also running out of space for bigger models!)
Still early in the build stage at this point.
This will be flown with a converted to 2.4 single channel C&S Electronics Falcon 1 transmitter using one of Phil G's single channel encoders.
I will have rudder, 3 position throttle and kick up elevator on this one.
Will post more as the build progresses.
- Nice stack of ribs.
Quite a few for such a small model.
- The project so far.
Fuse sides cut out, stab, elevator, fin & rudder made
A few fuselage formers. You may notice that I changed some of the formers shapes to suit
more modern internal equipment.
- The mighty Enya .09 series IV
with muffler

Looks great, I am looking forward for the building report. (and of course flying report later)
Three rubber escapements will be a real challenge.
BTW, great transmitter.

I should have written as designed "originally" it was intended for 3 escapements.
Mine will have three well behaved servos emulating single channel operation using the single button - only without
the simulated hanging up, rubber running down, skipping a signal, going out of range etc.!

I made some progress on the Executor.
The wing is coming along nicely should be finished it in a day or so.
- I have the ribs and spars setup in my trusty Adjusto-Jig.
A bit of a pain to setup but the wings always come out very straight
- The leading edge wing sheeting is glued in place top and bottom. You can see the yet to be shaped leading edge being held in place with popsicle sticks and #64 rubber bands while the glue drys. Being a simple wing without ailerons I can usually complete everything with the exception of the bottom center sheeting and bottom side wing tip braces in while in the jig.

Progress has slowed down on my Executor as the XHT module arrived for my C&S Electronics Falcon 1 single channel transmitter conversion.
As a result I have spent more time on that that building this. That will change as I have just finished the conversion.
- The completed wing & out of the jig.
It is a very rugged wing!
Tail group is built. Fuselage next.

Great looking model... Have you an image of the original a colour scheme ?

What finish are you going with tissue, film, nylon ??

A far as an image goes I only have the one from the magazine cover shot. (attached)
The scheme might be based on the original but not exactly. I like the swoops by the nose but will carry it under the nose and probably extend over the back side instead of ending on the sides. Have to give it some thought while I build the next model.
As much as I would like to see it covered and finished I cannot get myself to bake on a layer of plastic film. I have a few models covered in that media and it works great but I don't think it is right for this model. Thought about tissue over Mylar but I am sure I will get over that.
Right now leaning towards using Lite Span or Coverite "Cover Lite" with a coat of dope mainly because I have plenty of each.
Far too cold to dope outside. Might risk doing it in my basement workshop with a fan in the window.
Depends on the noise it creates from upstairs!
Very much looking towards flying this one with my converted C&S Falcon 1 single channel transmitter operating rudder, elevator & throttle.
