Never had any problems either,but they do strain the little servos,because there is resistance (which will lessen as the CA hinges wear in).I have used them for almost 2 decades on .40 to 1.20 size planes,which obviously have more powerful servos.
My #2 will get hingepoints and possibly one servo on rudder with a bit more torque,since I have really enjoy the KE capabitlies of this 260.
I had a glitch early today while at a park and had a rather rough landing.I doctored her up quickly and let her rip tonite,3 awesome flights.When I took it back to the pits,I noticed a big gap from the fuse to wing root.It seems that the glue joint had worked or broke loose from stress.This is the tab that bolts to the fuse with a 4-40 screw,this tab pulled out of the wing,but the antirotating pins were long enough to keep it from shifting (whew)
This might be something to keep an eye on,if you fly it hard or have a mishap
On another note I tried an APC 12x6E prop,it worked fine,but I am switching back to the APC 12x6 Slow flyer prop,it seems to put out much more low end thrust.My motor is a 910KV 480,the E prop maybe better for a 1200KV or higher,not sure,never had a high KV 480.
