The E Jet is based on a Jr. Nobler wing (rib set from Brodak). The moments and tail area are more of a "Fancherized Twister" sizing. With the extra weight of the 4000 4S1P battery, the flaps are Al Rabe ish. Flaps are 2 1/2" full length. The twin boom design was chosen to get the jet on centerline, all the surfaces are on centerline too. The jet is mounted 3/16" off the trailing edge in the profile center fuse. The battery is as far forward as needed to get the CG at the 20% cord line.
As I said in the prior post the ship comes off the ground just like it was a prop ship in about 15'. It doesn't lose speed in the maneuvers and does a very good wing over. I have only done 2 consecutive loops and eights but is was because of flight time and battery. I haven't done the vertical 8 cause as I was working up the nerve to try it I got side tracked for contests and work. The ship got put on the rake and I didn't get back to it last year. Hope to pull it out and start working with it soon.
The electric side has a E-flite in-runner BL 15 - 3600 KV motor. It pulls 42amps static at 38,500 rpm. I use a Castle Creations Edge 50ESP and a 3750 to 4000 4S1P battery pack. I have not found the longest flight time it would go and still have 20% headroom, was working up to that (would like to get to 5 mins but that might be a a bit to long).
If one were going to build one of these EDF stunters here is what I learned and would do different:
1) The max static thrust rating of the unit should have at least 20% reserve above the weight of the ship. Don't make the ship to small, 69 - 70mm fan is about like a full 2 cycle on a Fox 35. Base the design on what you would use for a low pitch/high rpm set up.
2) All inline arrangement works well.
3) Mount the EDF unit up close to the CG to reduce the need for a long nose moment to get the correct CG.
4) Make the battery box with extra 1" front and back to shift battery for balance.
