This is my scratch built J-20. I built it using the plans posted by the Mesa RC Foam Fighters.
I have really enjoyed flying my Flite Test F-22 Raptor so I decided to build another jet fighter.
I haven't been able to fly this one yet due to the lousy weather.
My thanks to Mesa RC for the plans.
Weight without battery is exactly one pound. I installed a 40A ESC with a Turnigy 2826-6 2200kv motor. Using an 1800mah 3s lipo the center of gravity is exactly where it should be. I installed two Towerpro 9g servos. They are working great in my F22 Raptor, so I hope they can handle the extra weight of this plane. The only 6x4 prop I have is the three blade in the picture. I have some two bladed props ordered and will switch to those when they get here. My wife made the decals with her Cricut Cutter.
The only change I made from the plans is I didn't install the bottom stabilizers. Depending on how it flies I may leave them off. I am concerned that they will get damaged when landing.
Update 4/12/13: Had the maiden flight today. Flew smooth and easy to control. Didn't even have to touch the trims. CG was right on. I didn't get too aggressive with it since there were some wind gusts. Very easy to land - it flys well at low speed. Didn't seem to be putting any strain on the electronics with the 6x4 three bladed prop. I may try a 7x4 and see what happens.
Here's a video of its second flight:
