Tu144 depron pusher
6mm Depron build of Russia's Tu144.
This as a sister to my sport edf Concorde.
Same build style - simplified fuselage and flat plate wing.
One change was to not use any BBQ / bamboo / cf stiffening but to sandwich two sheets of depron with laminating epoxy resin. The resulting wing is stiff over all its form unlike localized rod stiffening.
Power plants - twin Floater-jet motors 2140kv with 3s 1750 lipo each and 5.5x5.5 props.
Thrust is well over 1:1 ... actual measurements to be made once I have ironed out a few details after her maiden flights. She proved to be highly manouevrable and actually sensitive even though the elevons are tiny.
Here is the full build scenario and photos from the Wattflyer contest at start of thread.

There's also good reason why it was only posted up on WF additional to the Comp : I was stuck for time ... after Ukraine and then of to hospital - which I've just been released from !
