Sure there is some effect but not enough to throw plane out... Mix just puts a very small amount if deflection on elevator and aileron. Hardly noticeable unless you look closely to the surface. With little effect with a relatively small amount of air going over it. I think it helps general flight though, ie: bank turns and such.

Ok That make sense! I will go ahead and add the mixes into my planes! Thanks for the input.

I don't run any mixes on my planes, mainly because I just try to fine tune them to the point where they don't need it. If I have a plane that just can't be made to fly without a mix I just get rid of it and try another better designed plane. Pretty much all of my planes are set to fly hands off ke or with such little coupling it's no harder to fly it out than one with the mixes responding to wind conditions. This is probably why I stopped using a mix because it always seems like you just wind up flying it out all the time due to varying wind and the changing direction you are flying relative to wind direction anyway. As far as how this affects the rest of the flight envelope I can't say I notice any difference as long as the setup gives you a proper flying plane as opposed to one with a mix. But this is just me and I tend to just do what works for me. Like everything else in RC, you just have to experiment and spend a lot of time finding what works best for you. For me this is half the fun.

Your always going to have to fly a KE... a mix just gets you close to neutral stick inputs, but coupling effect changes at verying speeds, different CGs, and AOA. You are a jetti master if you could get all coupling out with tuning. What type of tuning are you doing? These plane we fly have a very low coupling which is one of the reasons they fly so great. My 60" edge mix is pretty dialed in... I could cut throttle, put in KE and slam rudder and it will drop with very little corrections from the other surfaces. Get down to the deck and start added throttle to maintain a low slow high AOA KE also with very little input other then fully deflected rudder. Other planes have been not so good. But to each his own... I went for months without KE mix before I realized I liked how it helped my KE.

ok guys I could really use some advice here!!!! About a month ago I started having problems with my 3 week old fortitude fuel tank. When I would turn my plane upside down and then right when I turned it back over it would die! So I put a new fortitude tank in and after about 3 weeks it just started doing it again. The plane is running great! And this morning I had another Dead stick! What should I do????

Maybe I'm just lucky in my setups or I'm so used to flying without mixes I don't realize how much I'm inputting but I can do a descending ke or hake with little or no inputs on all of my planes. Maybe it's time to try it again if I ever get a nice calm day to set up some mixes and see how it feels with the rest of the flight envelope. It's worth a try just in case I'm missing something. Heck, I'm a little better than I was a couple of years ago so maybe it will make a difference.

fuel tank is a rather simple device. Are you 100% sure its the tank?

What do you mean??? The only reason I say it is the fuel tank is because when I was having this issue before I put a brand new one in and it fixed my problem. Then today a month later with the new one it did it again. I took that tank out just now and put another one in there and it did not die on me, but.......I did seem to idle down a tiny bit as if it were wanting to die.. What do you mean Pressure under the cowl. This plane is my first love LOL and I would hate to lose it to something like this soo any help that you guys can give me I really appreciate it

I'm not into Gassers (yet), but this was just discussed in the past few days on the Fly Low thread.

Cowls not having enough Exit Venting to relieve the pressure in the cowl, causes issues with the engines cutting off when rolling Inverted.
