Snap Rolls

[P-Diddy]

I know I've said it before, but there have been several updates and new versions since, and yet it has still not been addressed.

Anyone read the current issue of Model Aviation? Notice that there is a section telling you how to do snap rolls. Now, notice that you do NOT use ailerons for a basic snap roll.

Try that in G3 or G3.5 and see what happens. That's right, no snap.

I've brought this up before, and people have told me I'm wrong. In full-scale airplanes when you do spin training, (or snap rolls, for that matter) you don't use the ailerons, only elevator and rudder. In the real world when I fly R/C, I do standard spins without ailerons, and yes it works.

In any case, I'm curious if anyone out there has tried this with other R/C simulators and whether or not the result is the same, better, etc. I've tried H9 FS One at a hobby shop, and it also did not snap or spin appropriately.

I'm interested in realistic aerodynamic behavior in a flight sim, and I'm wondering if Knife Edge is going to address this at some point or is it just considered "good enough" as is.

And no, I'm not bashing the software, I've owned it for a couple years and I've had lots of fun, but it IS lacking in realistic aerodynamic performance.

I find G3 to be fairly accurate with almost everything except spins and snaps. Aerofly Pro is a bit better at snap and spins but I don't have experience with any others (except FMS and FS1... stay far, far away from FS1).

aome one needs to update Wiki's definition of a snap (http://en.wikipedia.org/wiki/Aerobatics_%28radio-controlled_aircraft%29#Snap_rolls)

althoug there definition as found for full scale (http://en.wikipedia.org/wiki/Aerobatic_maneuver) is as you said.

I also found a few other sites that say RC use aleron...

NE way. Did you increase the Stall severity and Stall moment of the Aircraft... I found that these help... + there is a Snap boost inthe editor that could help...

Give me some time and I might (If posable) get an AV up here.. Rite now my 20 mth old monky is trying to comunicate with me...

Ehh... baaaanhhh abb Oie u ed us. (Nah still dont know what he is saying ;)

Hang on... I'lll do a recording with him in the background :P

I was having sucess with this one. but i had to do a little dip before the up elevator and the other thing is to not use max throws. IE use Low rates and you will need to use from 50 to 75 rudder. Found there were many different ways to enter. but that was by fluke. so I am now in the process of practicing with this AV.

PS it would be helpfull if you could test it for its performance during other Manouvers etc. just to make sure the changes did not have an adverse effect on other manouvers.

PS. OP has just made a post (http://www.knifeedge.com/forums/showthread.php?t=17535). and DHK has another post (http://www.knifeedge.com/forums/showthread.php?t=17498) on how to change Factors from start to finish..

PS. Couldnt make a recording. My boy was playing with my wifes body lotion and i had to clean up the mess. :rolleyes:

Whether or not you need to add aileron to start a snap is dependant upon the plane design.

The same article in this months mag states as much as well.

That said adjusting the "Stall Severity" to 100% or below will return the snap behaviour to what you are probably expecting.

Just remember to do this on ALL of the wing surfaces which includes the rudder and elevator.

Yes, that's true, but considering that NONE of the stock planes, or add-on planes, will snap realistically says that something should probably be done on a global level with the software. If it were just some of the planes that I had a problem snapping, then that would be just fine, but it's ALL of them.

Okay, so I can go in and edit each and every plane to get the desired snap effect, and that's fine, I can do that, but KE should really fix it to be realistic from the get-go.
