How do you deployed your spoileron? Mytus or all other 2 servo wing type sailplane

[Magna]

Hi all sailplane owner and especially Mytus Owner,

So far I know Adam and Flutterbug is using the spoileron for landing on their mytus. How about the rest? on spoileron type plane? I'm looking at 2 servo wing type. No brake or flap setup!

And what is your spoileron setup? Ie did you mix it, or is it manual?
How many degree/travel of your spoileron? How much left for aileron?
Did you feel that you are losing aileron effectiveness much?
Did you mix in elevator?

When did you deploy the spoileron during the landing approach?

When you testing it out in the high sky, how did you know that it is slowing down your plane? Or it is obvious that you just need to see it to know it?

I intend to mix the elev/spoileron into my throttle stick. Unfortunately due to the eclipse limitation, I can only mix it in such way that when my throttle stick is at the lowest(off motor) the spoileron is maximally deployed. As the throttle advance it will shut off the spoileron proportionately. When throttle stick at neutral/center point, the spoileron is off. At this point, the throttle should be about 40% on.

My deployment step is: Off throttle, align the approach and kicks in the spoileron. However, it will be deployed fast as the eclipse have no delay mode in deploying the spoileron.

Any thoughts?

I use spoilerons on a 1.6M v-tail warmliner. They are on a 3-way switch (MPX Cockpit MM tx), I have a little 'up' elevator compensation mixed in. The ailerons go up maybe 40 degrees on full throw, this does reduce the aileron effectiveness quite a bit. My landing procedure is first to switch in rudder/aileron mix, then deploy stage 1 spoilerons on the downwind leg. When lined up on finals I will deploy stage 2 spoilerons if necessary. If it's windy (turbulent) I don't normally use stage 2 because the model is sluggish, even with the rudder helping.

They don't noticeably slow the model, but do increase the sink rate (which is what I'm after).

Have spoilerons on my "souped up" Dymond Crazee.
Aileron servos on channel 1 & 6, find "Landing Mode" on your program and dial in deflections.
All is controlled by a switch, top left.
Amazed how easy it was to set up. Also dialed in some differential 10mm up and 5mm down for nice rolls. Have a geared Endo on 8 cells=ZOOOOOOM.

I have my Mytus set up on a Flash 5 and don’t know how the Eclipse works. Aileron servos are on 1 & 5 with spoilerons on a right three position switch as well as on throttle. The switch is set so the middle position = no spoilerons, low position mild and up = full. Full is short of full servo deflection so there is still some up aileron when full spoilers are deployed.

However, I hardly ever use the switch. I like the proportional control of the throttle Stick. This is set so full throttle = no spoilerons. The less throttle the more spoileron. Full spoileron is again somewhat less than full servo defection to give some up aileron at full spoileron defection. Ideally one would set negative differential with spoilerons but this is not possible with the Flash 5. I also don’t have elevator mixed in with spoilerons which I can do with the Flash 5.

I cannot tell at altitude whether spoilerons are deployed so I monitor my throttle stick to make sure it is at full throttle. I have had times when I could not get the plane to go up, even in house lifting thermals and then noticed I have partial spoilerons deployed.

I set up my landings fairly high without a lot of excess speed but enough for good maneuverability. I then use the throttle stick to control the glideslope and am usually able to get the plane to land at my feet. I don’t seem to have any problems turning with spoilerons on. There is probably a little flair when deploying spoilerons but it is so mild or easily corrected I don’t seem to notice it.

Hi Bernie/Flutterbug

What do you mean by......

.... I then use the throttle stick to control the glideslope and am usually able to get the plane to land at my feet....

So if you are moving your throttle stick, I take it that your motor is on as well unless your esc only kicks in from the neutral point upward?

I take it that your spoileron is fixed and not proportionately control?

I'd like to know more about controlling spoilers with throttle as well. I dont' have anything set up on the Mytus yet and I'm looking around for a radio that will let me do it. I was looking at the Eclipse 7. Is that the right choice?

Do you HAVE to set up spoilerons with the throttle? I'd like a setup where you just toggle a switch and they pop up "X" amount.

Popping up with a switch can lead to surprising results (go see my picture in the recent Falcon thread here).. I have my spoilers on the throttle switch with my Filip, and plan to migrate all of my models to this style, with the throttle on TWO switches - one to bring it up to fast idle, then the spring-loaded snap-roll switch for full power.

Andy, can you explain that a little more?

[Andy W]

Just as I said.. one switch (on/off type) puts the motor @ about 30% position (PMX SW# -> #8 (I have ESC on #8) +30%) and the other (spring loaded snap-roll) PMX SW# -> #8 +100%.. so I turn the motor on with the on/off switch for launch - enough power to cruise or a shallow climb, but then hit the snap-roll switch for the full-power climb, then let go of that to level out, then kill the first switch to turn off motor. Works nicely on an LMR glider - need to modify programming for F5B as I still want idle capability for launch, but then snap-roll switch needs to go from 0-100% (it's a problem that most controllers will see the new '130% end-point' from the first method and not give full throttle on snap-roll switch alone - not a problem for my Aveox L160's, however..)

thanks.
