I'm building one. It will be powered by an electric motor pulled from a P38 Lightening foamie. I don't have much experience with electric motors either!
Having said that I have been given a Cox 049 with five litres of high octane glow fuel so I may build a second one for that.
I am going to have a go at covering the wing in tissue over doculam.

For flying in various conditions Barry, I use a variety of lipos with an 8 x 4 sports prop.
Due to belly landings, I use a tough black prop unknown make
The 12v motor gives the option of 2S or 3S packs, from 500 - 800mAh
In light breeze conditions, the 2S is fine for flight and in windier conditions I have a heavy 800ma 3S

My Sharkie uses a 2S 800 LiPo which yields a flight time of about 10 minutes if I'm gentle and 8 minutes if I'm not. I also have a small bit of lead in the nose so a smaller battery would not be an advantage.
Props are held on with an 'O' ring which improves prop life significantly.

Without digging mine out of the loft I cannot remember the electric set up I use but at a guess 3s 800.
I built the original when it was first published and fitted a Cox TD 049. Thinking that 1/8th" rudder travel must have been a misprint I used 1/4" Yikes! And no throttle!
I also have another wing for it with 1/2 the dihedral and ailerons. Obviously more rudder travel was needed on this but made the mistake of trying to fly the rud/elev one on the wrong Tx memory. Good job they are tough.
