Power Systems Ebook by Dave Powers: http://www.rcpowers.com/E-Book... This is a best seller for us. This ebook answers some of the most commonly asked good questions we get. WHAT PROP, MOTOR, BATTERY, ETC DO YOU GET FOR YOUR PLANE??? The secret to this is you build or buy the ENTIRE airplane around a "magic prop." Click on the link above for a "infomercial video" on it. We have 3 previous test flights of this project here: http://www.youtube.com/profile... '>http://www.youtube.com/profile... Ok, so what I am up to with this project is to "BREAK THROUGH THE HIGH ALPHA BARRIER." What that means is I am trying to get a RC jet to fly at about walking speed with its nose at 70-90 degrees (most all airplanes stall and fall when they hit 30-45 degrees because their wings are no longer getting lift, see. 3 Ways I am doing this. All 3 are needed and work together: 1) I have both my motors able to "Thrust Vector", Google that term if you need to... This gives me control with or without airspeed by just moving the thrust of my motors around. 2) I have the canards (pitch/up and down control) and my ailerons (roll control) flip back into the wind with switches on my controller once the plane exceeds 40 degrees. Without this, these control surfaces would be trying to stall and crash the plane for me, rather than facing back into the wind and giving me control at high angles of attack (40 degrees and above). 3) Gyro stabilization. So once I got the above 2 to work, I then installed a gyro on each axis: 1 for pitch (up and down) 1 for roll, and one for the rudders (yaw). The plane reacts so fast and wiggles around that I need the super fast gyros to make corrections within microseconds, and they do just that. They work perfect, test successful. Another reason for the gyro stabilization is I have my center of gravity (CG or balance point) so far back that the plane is incredibly unstable! WHY WOULD I DO THIS? It's a trade off: More stability = Less maneuverability. And More maneuverability = less stability. So by having my CG far back, the plane is always wanting to lifts its nose in the air (which is what I want for high alpha). The CG also makes the controls respond MUCH faster (which is also what I want for stunts). The cost is, it's so squirrely and jumpy, that I can barley control it on my own. The human reaction speed is just way too slow to be able to deal with the dozens of micro-corrections that need to be done each second just to get the plane to fly straight! Crazy, huh? Well anyway, it all works, so how do ya like that. Been working on this idea for about a year. Turns out, all this I figured out on my own is pretty much what the REAL SU-35s and 37s do! Well, at least what I can figure anyway. The final stage of testing is training the pilot (me) to be able to fly it better and better and really discover its abilities. So I'll fly this plane until it finally falls apart or crashes real good. It's probably got another month of life in it at best. In the meantime, I'll be starting construction on the FINAL one! I have a list of about 50 minor construction improvements for the new one. The final one will look as good as I can make an RC jet look. I am planing on the blue camo that the Russians use for their Su-35s. Subscribe and stay tuned to our YouTube channel for updates!

UPDATE 1 Hey I was just thinking for guys with just a scratch built or store bought parkjet - you could put just ONE gyro on the pitch and this would allow you to move your CG farther back. Farther back CG is going to make better use of your flaps, way tighter loops, and more maneuverable all the way around and at the same time keep the plane under control for you especially with landing!
