(Yes, the art of flying has many rights & wrongs that are not simply matters of opinion - and this happens to be one of them. ) The fact that you "need" the mix on both of your planes when nobody else does should tell you that you need to change how you trim your planes. But for some reason, you don't want to do things correctly. So be it. However - if you ever wish to progress from the beginner/novice skill level to intermediate, you'll have to unlearn a bunch of very bad habits. Your call.

Good luck.

To me the CC is a tiny fun plane. It is tiny, I have fun, it is a plane. What is funny is my flights seems to be just as "qualified" as yours. For some reason some members here seem to share the same posting characteristics, it is most curious. Okay, I think we are done here.

Well, I know why she banks left. The wings appear to be twisted. It's very noticeable in the two head-on shots. Notice how the LE of the port wing twists downward outside of the strut & the starboard wing twists upward? Downward twist near the wingtip is called washout. A bit of washout on a non-aerobatic plane is a good thing. The reduced AoA near the wingtips assures that the inboard part of the wing will stall before the outboard part. This makes planes a lot more friendly during slow-flight because it reduces the tendency for tip-stalls & also increases aileron effectiveness at low speeds. When the outer part of the wing has a higher AoA than the inner part, the opposite is true. That is called wash-in, and it is highly undesirable. It will make a plane downright evil at low speed.

In your case, it appears that the port wing has excessive washout, and the starboard wing appears to have a ton of wash-in. Not only is that causing the left-banking tendency, it may also be causing the ballooning. The next step is to remove the struts & adjust them to the suggested lengths in the CC guide. The metal tips are threaded. Just crank 'em in or out, as needed. Note that the left & right struts are not interchangeable.

Once you've done that, take some more pics. Also - be absolutely sure to zero all tx trim, then fire-up the plane & let it initialize (this centers the servos). Be sure that you do not engage AS3X, as doing that will screw everything up at this point. Once the plane initializes, disconnect the batt, and then mechanically center all control surfaces. Also, measure the CG, and adjust it to 27mm aft from the LE. Be sure that you do all of the above before attempting to fly the plane again.

I looked at my paper manual and the manual I downloaded online and couldn't find any information on the struts. What are the measurements supposed to be, or does it not matter so long as the front struts on each side and the rear struts on each side are the same as one another?

I agree 1000%
When I started flying RC it was the norm to set up an aircraft to fly on the basic 4 Chanel tx no mix or expo on the old analog 4 Chanel tx so I had to mechanically mix throttle and pitch on my first glow powered heli no gyro on the tail so I had to compensate for main rotor torque manually (talk about busy thumbs) it took everything I had just to get in air

My CC came with one wing straight and the other wing had washout.
I didn't know that the metal rod in the struts was threaded so I re-bent the metal rod so that my wings had the same amount of washout.

Yes it is astounding how they make no mention of this in the very inadequate manual.

No prob, thank you for the wheels.
After surveying the past few pages of this thread, and as a new CC owner- first, thanks to turboparker for sharing his vast and well-written knowledge that is applicable to all of my other planes, and second- is this plane hard to setup cg wise? Followed turboparker's guide and balanced my CC at 37 mm aft from root, have not maidened yet. Have flaps with a 4 second delay and full/half/zero flap settings.

Not astounding at all. Adjustment shouldn't be necessary. The factory assembly instructions are simply not followed, or inspected. Heck it's such a simple setting it shouldn't -need- inspection. Then again it's such a simple adjustment that mistakes shouldn't happen either, but obviously they do. Remember those little pieces of paper you used to find in a box or a pair of pants that said 'Inspected by #14?' Or even a -stamp- on an electronic device or the manual? That was a generation or two ago. No one cares any more.

Maybe the Chinese manufacturer thought, "How will we fasten the metal rod in the strut? Glue takes too long to dry. Let's thread the rod. Don't tell Horizon about it."
