The bend in it right at the front of the saddle looks like she has taken a beating. How many hours are on that spring? Sometimes when you beef up a sacrificial part, it makes you break other parts that are much more expensive and time consuming to replace.
Agreed. If you use one, you automatically use the other. Rudder/aileron interconnected airplanes make one pretty lazy. It would take some big rotor type winds to keep me from being able to level my Avid or any KF I have flown to date. Either they guy is not moving the stick to full deflection or not using his feet. If he is then there is something wrong in the control system or structure.
To each his own. If you want to make videos do so, if you want to overhype them just like every other reality TV show or youtube sensation then you better be prepared for some feed back. Doing VG testing is nothing new. I have done it, big frickin whoop. You stall and if you don't have the ball centered and keep the stick in your lap your going to spin. That is flying 101. To make a deal and talk about how scary it is just means that you are probably sporting a man bun and fly tricycle gear planes Yes some of my comment is in jest as I can't believe how twisted up some get over things like this.
The complete build manual including rigging is located in the link above. Without the F7A mod, you probably have more up travel than down on the roll input. With mine, when I pull in full flaps I get very little addition "down" movement on the flaperon but the other side goes up as usual. These birds are pretty responsive in roll control. If he can't level a wing something is loose and flopping. Check the rib tails and the complete system for slop. I have only been in one situation where I could not level the wings with just the stick and that was in a nasty mountain rotor. You can fly the plane with rudder alone so if he can't keep wings level something is wrong in a big way. I am not sure how Chris is getting 40 degrees down on his bird, I can't even come close to that on mine. That seems to me like your getting well into roll reversal territory where the drag of the down can't be overcome by the opposite side going up and you roll in the opposite direction you intended.
Avids and kitfoxes demand a lot of rudder use doe to adverse yaw with the original mixer system. Do you have the updated F7A control arms in the mixer? When in a good crosswind I limit the flap use as well.
If having fun playing with stalls scares the crap out of you then perhaps flying aint your thing. He is talking smack for the benefit of the video and to over sensationalize it just like ever other youtube sensation. Also remember that this is on the KF 7 wing that has a different airfoil than the early model KF. The most benefit you will see from the VGs is probably when you yanking and banking as most pilots I know or have seen don't or wont drag the plane in way behind the power curve at high angles of attack.
There is a difference. When I went over to help Bob with his I noticed that right off the bat and questioned him on it. He pulled out the book and showed me because I might have mentioned that he was getting old and loosing his mind
