Flight Mixes, do they really help?

[BrImMa]

When I setup my airplanes (for IMAC) and I get to the point where I am doing rudder mixing to elevator, aileron, etc. I like to do flat turns. As Seth said before you should put you mix on a graph. I do a flat turn with a small amount of rudder, look for the tendencies, and adjust. The next time around I use a little more rudder and adjust. The process keeps going till I am at 100% with the rudder throw and then I start all over and do it in the opposite directing. This is only one of many mixes in my airplane. It is a lot of work but it cuts your flying workload down dramaticly.

WOAH!!!!!

Every man to his own eh boys?

FWIW, I used to do the same till i figured out the reason my wings where rocking. It was because one wing was not fully stalled. Once you figure out the AOA and airspeed you will be in business.

I agree cheating with mixes for harriers is great ..... or at least till I almost planted one. I was in a situation where I need all the lift I had and forgot the spoilerons on. Close call..

Kill the mix and better you flying.

As far as mixing for KE roll and pitch coupling, i would never be with out it. As stated before, the plane will need the same mixing at almost every attitude. I it just more obvious in KE flight. I know it will clean up a wing over and other rudder based manuvers.

So I'm wondering: If I program some mixes to correct bad tendencies of a plane, will these help me when the plane is, lets say inverted? Or just make things worse? I mean one could set up a whole bunch of mixes, but they would need to be switched on and off all the time depending on aircraft's position, right? Ok, I could program downline mix on low throttle and switch it off on landing, but what about all the knife edge, rudder to aileron and other mixes I may (hopefully not ) need? Chris

I posted this elsewhere on these forums... thought it might be helpful here.....

OK.... if I may.... this is how I setup a large gas or electric plane with an emphasis on 3D.....

I program a model and call it "TEMPLATE".....

I max out all ATV's to 140% (155% total servo throw.. FUTABA users know what I mean).... I leave the throttle at +/- 100% though.

I setup D/R so that the Elev, Rudder and Ailerons are all switched in and out of D/R with one switch. I arrange the control horns and servo arms lengths so that I get "stop-to-stop" travel on each flipper... 45 degrees'ish. SOmetimes on ailerons, I am happy with +/-35 degrees.. (As fast ailerons get me in trouble )

I setup the Expo to about 55 to 65% on all three primary flippers... in the high rate mode.....
I match the expo in low rate to coincide with the high rate expo around neutral... what I mean is that with sticks within say 15%'ish of neutral or center, the hi-rate and lo-rate expo curves are nearly identical. As a result, the plane feels the same around mid-stick in both hi & lo rates.
Initially, I set Lo-Rate to 50% on the elev and ails and 65% on the rudder...

I usually set up the throttle curve so that the bottom 50%'ish of the stick travel maps out to something like 30% percent of the carb travel.. (gas only as the gas motors seem to have more sensitive response on the bottom end)....

I initially setup about 3 to 5% UP elevator with L&R rudder... and 3% percent opposite aileron to rudder in the pre-mixes... (with well designed modern planes... this is very close.. and even if it isn't.. it poses not flight risk)... I have only found the opposite aileron mix to not be the case with Midwing Extras.. (260) and Katanas....

I setup low rates in the air so that I can do a slow rolling circle at 50% power and have enuff rudder to not loose altitude thru the KE parts of the roller.... I setup lo-rate elevator to be enuff to clearly initiate a snap roll without bury'ing the plane too deep.....

This template can then be copied and renamed for all future planes.... and has been a fairly good starting point for me....

I also setup the timer to be switched on and off by the throttle stick.... (Electrics) If the throttle is above 10%, the timer counts down..... below 10%... the timer stops.

Hopefully the above stuff makes sense and isn't too frought with errors!!! lol

I may have to try this...Thanks for the info!!!

Now to figure out how to flight trim in 15mph+ winds with gusts on the coast...LOL!!!

Hey, thanks for the explanation, it's pretty helpful.My guess is that getting the calm day and adjusting all the stuff would probably take a few weeks

Or a few months...
