I had to make it smaller and lighter than OP's 64 or 70 mm EDF planes. Ended up with 15.75" WS. The plane is just DTF. Plane alone only weighs 1.9 ounces. With EDF, ESC, receiver and two 9 gram servos, it came out to 6.2 ounces without battery.
I'll be using an 850 mAh, 3S battery that weighs 2.3 ounces, AUW is 8.5 ounces.
Held it straight up and at full throttle, it wanted to take off, so it has higher thrust than weight.
Couldn't fit the battery under the canopy because it need to be so far foward, so I put it on the bottom. Not as clean as the original, but it will have to do. Added some rails to the bottom to protect the battery. Made the wing shape triangular. Put the ESC with heat sink on the outside, hence no hood scoops.
The nozzle isn't real efficient. It's a bottom from a plastic fruit cup. Same diameter as the original plane. The EDF was too small for a styrofoam cup, so it's just a DTF cylinder.
Should be a fun, fast little plane! Thanks again OP!
