RE: Snap Roll (no arguments, please)
 

John, the 14MZ introduced the concept of 'logic' for conditions which allows you to define multiple triggers to activate conditions. The capability of doing this also exists in the 12Z and 12FG, I am not sure about the 8FG. Anyway, you can set up the condition so it is activated by full elev AND full aileron, for example. This is a very simple example of what 'logic' can do, it has far more functional capability than what I just described.

You set up 'logic' thru the condition programming screens.

Just a quick O/T, the 8FG has logic switches on flight conditions, but sadly only glider and heli menu offers flight condition programming so you're not able to use it that way for F3A. (I tried)

So everything I've read so far regarding a snap roll (mostly full scale applicatio-s) says nothing about ailerons. Quick elevator to stall, rudder to initiate spin, opposite rudder to stop. Surprisingly I think that's what the MAN article said. Obviously not everything scales down equally, so maybe ailerons are needed on our models to make it pretty? Saw somewhere something about spins vs snaps; sounds to me like snap is really a horizontal spin.

Unfortunately I found nothing in nsrca website judging criteria, though not sure about.the manual.

Scott,

I disagree here. I think snapping in always looks funny, especially on more than one rotation.

Thanks Don and BJR(Brian?)

Now that I now I can use booleans in my 12Z, figuring out how to do it was not hard.
 I defy you to extract that information from the manual, however. A search for "logic" turns up exactly nothing.
Don, ever get back to Colorado? Arvada has a contest again.

John, the Logic funtion was a later software update so is not in the mnual. You have to find the description of one of the updates, I think.

Now that you know about logic, trigger points, etc, have you figured out hysterisis yet... ;-)

I get back to the Denver area occasionally, mainly because of family. Still a very nice area tho the growth is still amazing.

Woodie,
I checked the current version of the 12Z manual. I looked for update documentation and I couldn't find anything about the "LOGIC" function.
Figuring out hysteresis is one thing, finding a use for it is another. Maybe gear door operation but I don't see a need for it in pattern.

I use logic switching on my setups.
I divide the throttle into 3 positions, lo medium and high
Then use the logic switching on each different throttle position
98% rudder and 98% aileron trigger, they untrigger and about 50% on each


So what that means i can adjust the throws for snaps at three throttle positions
Then i can customise each.

So for example at full power i can adjust a left positive, right positive, left negative, right negative snap all individually

Same for mid and low throttle positions.

I then have a switch for the spins, this gives an idle. And disables the logic switching(snap logic) But lets me customise the throws for my spins.
I also have another switch for the rolling circle, again it disables the logic switching(snap logic) but gives me the chance to customise throws expo etc for the circle

Hope this makes sense. Oh and i'm using the 14MZ

I replaced the switch for the snap condition with logic incorporating both the aileron and rudder sticks using symmetrical hsyteresis and placed  the spin condition at a higher priority. I flew this configuration this morning.
Couldn't tell the difference.
No longer can I forget to turn the snap switch off.

Thanks for all the help.
