Les Rudd Go-Jet on the way

Inspired by Mark Dean's fantastic Go-Jet at Ponte in the summer, I've been building one myself, which is going to be rudder-elevator and electric powered.

The fuselage is pretty much done, the trickiest bit being the routing of the elevator control snakes up through the highly swept back fin to the high TV tail. Torque rod for the rudder actuation is in, with some old school wire bending. Motor is mounted - when I cut out the sides I extended the fuselage sides to hide the motor itself, the reason for which will become apparent later.

Just started on the wing yesterday, which is my favourite type of wing construction, 1/16th sheet wing skins, a few ribs, no spar. The upper and lower skins are done, ribs are in place and the aliphatic is going off overnight. This is all being built from my diminishing stock of 1970's vintage Solarbo balsa :)

Electric has a kind of elevator in the throttle control so I wouldn’t bother too much about it. It was different in the old days when you had a few scary minutes with an engine running at full speed.

Unwaxed dental floss works amazingly well for the hinges and will almost be invisible after a few coats of dope

That's dental floss that I've used for the rudder and elevator hinges Tobe - surfaces covered with 38um laminating film first before drilling out the holes for the stitching. Gives a lovely friction-free hinge.

Covered the Go-Jet with 38um matt laminating film today, all ready for painting. I'm not going to double cover with tissue in this case, to save a little weight.

Don´t worry too much about elevator control, my Go-jet flies beautifully without it. Even loops and barrel rolls are a joy to fly.
It is one of my favorite S/C models. It can be flown in moderate wind conditions too and penetrates very well.

They are a quick build if anybody is after a new s/c model.

When did you build yours Frank.?

Great fun on rudder and throttle.
