I am Shawn Morrison, from Orlando, FL and I have been into RC helicopters and quad-copters for the past 10 years. I followed RC Explorer, built David's tri-copter, and had some fun with that too. I got into the hobby because I wanted to film Pro Wakeboarders from the air with a helicopter. I had some bad experiences with expensive crashes that delayed my interest, but over time, as technology got better, I kept trying. I finally succeded in my desire to film from the air, and I, somehow ran across FliteTest.com.
At first, I just looked up any multi-rotor videos I could find, because I wasn't interested in planes at the time. But, after watching several of their very entertaining videos, I started watching plane videos also. Once they came out with the Disney Planes characters, I was hooked, and for the past 6 months I have been perfecting my building and flying skills. Here is my own creation, inspired by FliteTest and crispy, from http://foamconceptjets.yolasite.com, with similar building techniques from the flitetest f-22. It was a miracle that It flew, because, I just got lucky, but It flies so great. It is extremely fast, and has very similar flight style as the f-22.
The only flaw in the design so far, that I have seen, is the small surface area between where all of the electronics mount, and the rest of the plane. I tried to reinforce it with tongue depressers, but it still flexes a little. But, even with that flexing, it still flys awesome and it is so easy to build. Any helpful tips would be greatly appreciated.
I was going to make a build video, but the build is almost exactly like the f-22 that I will link below.
I didn't include the angles in the plans for the winglets, because I just kinda played around with different angles, till I got the one I liked. You can cut out a triangle to your desired angle.
The bottom vertical stabilizers were just lined up about a tongue depresser width from the prop slot.
The ailerons were cut, by lining up a ruler across the two arches in the tail.
I used the ft elements firewall to mount the motor.
I have no idea where the balance point is, I just got lucky mounting all of the electronics inside the front area.
I cut two lines in the front area to access the battery, and made a score line in the front to fold it up.
I hope you like it. This is definately my most fun plane to fly right now.

Although, this plane flew very well, I am working to improve it. Working on the Bat 2.0.
It will have the tongue depressers sandwiched between two pieces of foam board. I haven't flown it yet.

My two cents: Put a KFm2 airfoil on the wing which will give more strength and lift.
