Guy,

This is the original kit from the '60's or early '70's.  It is still all balsa (incl. balsa and ply doublers).  The main indication is the rubber band wing fastening.  The later revised kit's changes were lite-ply fuse sides but wing bolts.
re: EDF related questions- I know nothing.
re: nose wheel. Twin EDF tail dragger is radical.  If form follows function then that explains why there are few or no tail dragger jets.
re: nose wheel servo- If you are going twin EDF, where are you putting them?  If on the wing, finish the nose and put the servo ahead of the firewall holding the nose gear. Consider putting the nose wheel bearing plate ahead of the firewall as well.  This way the belcrank can be as far away from the planned battery hatch.

My two cents.

Quick calculation and the weight would be likely around 8 lbs. due to battery and 2 EDFs.  :o
QUESTIONS:
1- Should it be powered by 2 batteries or one?  The ESC are rated 70 AMPS and for 4-6 cells.
2- The nose wheel and steering is in the way of the planned battery tray. How about a tail wheel instead?
3- I need to test the engine/ESC/battery combination prior to mounting.  Any suggestions on test stand?
4- Wings are rubber bands mounted, how about changing to bolt-on for more rigidity?
Thank you.

Winter project identified.
I had 2 - 70 mm EDFs laying around.
With 2 kg of thrust each, that should be plenty for a 6-7 pounds airplane.
Bunch of stuff to figure out prior to starting the build.
That will be fun!!    ;D

That was a superb day provided you were not intimidated by revengeful winds.  They were as fast vertically as horizontally after interference by the trees behind us.
Yet despite the challenges, some members had superb landings.
Thanks for the dogs.

Great fun today! Steady winds from the west, nice weather.
Now I need to figure out why water gets inside the boats?!?

Fabulous news  @Michael . Our thanks to the board for this singularly important accomplishment.

How much do we pay per year ?  Any surcharges for trampled crops resulting from aircraft retrievals in the planted areas surrounding our field?

Thanks again guys !

Nerve wrecking day.
I had to cut a slot in the hull to fit the keel trunk.
Now alignment and a lot of epoxy.
