Art-tech Christen Eagle Manual
2 Hangar 9 Christen Eagle II 90 ARF WARNING: Read the ENTIRE instruction manual to become familiar with the features of the product before operating. Jun 22, 2009 Art Tech Christen Eagle. Anyone know where the CG point is on this plane? I was given a shop soiled one but it has no manual.
Hey guys, I just really felt like sharing my first doppeldecker with the lot of ya She's around 680g with the included 3S 1300mAh lipo and the brushless motor seems very powerful (have no more detailed specs as of now). But boy am I glad I have a couple of 2200mAh spare ones. I think she's a real beauty - sorry about the low-res pictures, but right now I only have a gum cam at my disposal (which should also serve as a nice source for cockpit view vids). Since this is my first biplane: anything crazy I should know about (hand) launching this baby? Have a good one, guys! Edit: Ok, specs in manual are not correct: 590g with stock lipo and 640g with one of my 2200mAhs. This looks like the same basic plane as the Cox Christen Eagle that was out a couple years ago.
I have had 2, still have one.and it flys very nicley. It will take off smooth surfaces with ease.but not from grass.unless u fly from grass golf greens. If it has the same outrunner motor, it will have good power, not unlimited by any means, but good for sport flying. The included battery (at least mine) were not of great quality, but did do an ok job. They did not have balancing taps, and one was severely out of balance from the start, and didnt last long. Have fun, and enjoy the plane!! Congrats Chris, you have yourself a very nice Christen Eagle.
And yes, it is exactly the same as the model Cox was distrbuting when they were still in business. Art Tech is of course the manufacurer, and they did a fine job too. I have always found it to be perfectly powered, and very light on it's wings. An agile and fun plane to fly, and not as difficult as it might seem to be at first sight. This is owed to it's light wingloading mainly I think. I have two of the Cox distrbuted models. One which I have been flying for over two years now, and the other I keep in it's box for safe keeping.
Mine's never been crashed, and is still in mint condition. The only problem ever experienced was the ESC failed last year, but was on the ground when it did. Replaced it with a CC T-bird 18 and all was well again.
Now I see that the one you have does not have the upper ailerons active, you can make them active by cutting the ends loose, and then using a horn on each near the trailing edge, and then make a connecting rod threaded at one end, and make a Z bend at the other. You can see mine in this closeup photo of it. Congrats Chris, you have yourself a very nice Christen Eagle.

I am by no means a 3D expert, but I do have sufficient experience with 4-channel planes, so I am all excited about this one! I was wondering about the upper ailerons, that's a brilliant idea. Should make for some nice loops;-) How does it fly with just the two ailerons?
Thanks everyone, I will hopefully be able to maiden it this weekend. Very stable and it can perform looooong loops (and that's without double ailerons). I have been in RC since 1984 with a small hiatus and have been flying full scale aerobatic planes since 1991 (currently flying a Harmon Rocket II I built), and I don't remember ailerons being a major factor in the loop other than to keep the wings level. What are you talking about when you mention double ailerons and a loop? I'm not trying to be a smartass; just that maybe I can learn something.

Jim Hey man, don't worry, you probably know a LOT more about this kinda tech stuff than me What I am saying is: I thought that using the ailerons on both decks would increase loop maneuverability (as opposed to just the ones on the lower deck, as is the case on my plane right now). Have I been misguided???
Edit: Also, wouldn't this increase the Eagle's roll ability, using ailerons on both decks? It rolls kinda slowly the way it's set up now (looks beautiful though).

The CHRISTEN EAGLE II was designed with the intermediate/advanced sport flyer in mind. It is a semi scale airplane which is easy to fly and quick to assemble. The airframe is conventionally built using balsa, plywood to make it stronger than the average ARTF, yet the design allows the aeroplane to be kept light. This will ensure proper as- sembly as the CHRISTEN EAGLE II is made from natural materials and minor adjustments may have to be made. The paint and plastic parts used in this kit are fuel proof.
