Question
Tx Programming for RES Glider

I am relatively new to soaring and have a Mystique RES on it's way. I have a black Spektrum DX-7 transmitter. My flying club is mostly powered planes (so there's nobody to ask) but I'd like to start out by setting my radio up like sailplane pilots tend to. Is there a switch that is commonly used to control the spoilers or a way that spoilers are most often programmed? I'd hate to progress further only to learn a year from now that I have my radio programmed in a non-standard manner and need to re-learn a new configuration.

Good Question

I can tell you how I set it up, but I don't think there is a "standard". If there is, you'll find out about it here.

My spoilers are set up on the left stick, with down (toward you) is no spoiler and full up, spoiler fully deployed.

Landing I usually set the spoilers about 1/2 way and judge the model. If it sinks too fast, put the spoiler down. Not sinking enough, add spoiler.

I have spoilers on the LH throttle stick, but the direction is reversed. Forward is spoilers closed, aft is open.

Why? Because I like to rest my thumb on the rudder stick when I fly a full house sailplane to add rudder inputs in a turn, and to be sure the flaps are up in all configurations except landing. It's more comfortable if the stick is on the forward stop while that's happening.

In my mind stick forward means speed (a holdover from power models) so flaps are up. To slow down lower the flaps by pulling the throttle stick back. Same logic with spoilers, although they work by spoiling lift, not slowing you down.

If you progress beyond RES into scale or F3X type molded sailplanes with advanced radio programming I think you'll find most pilots use the stick forward/flaps up/spoilers closed convention. It makes rudder inputs easier and more precise without worrying about whether the spoilers or flaps are accidentally deploying while you're turning in a thermal.

It's not programming but you might field trip over to Down East Soaring Society. I think they are in the Wilson area which is about 2 hours from your neck of the woods. Might be worth the trip.

Throttle stick down for closed and up for deployed on spoilers or flaps has worked for me for over 40 years. There is no right or wrong only what works for you. YMMV

I'm planning on making it to Joe Nall for a few days. I don't know if anyone will be soaring but I'm hoping I can bump into a few pilots to get some advice.

RES programming

You can set up a RES sailplane (I'm assuming with motor?) in either Acro or Sail menus. The limitation on model type in Sailplane is that there is no option for 'one aileron (rudder) two flap (spoiler).
I finished up using Acro on my large RES soarer, and it works perfectly, but involved some head-scratching.
Doing it again, I would go for Sail, and simply ignore the second Aileron channel (and avoid programming any differential or flap into the ailerons).
There was a useful discussion on Duworm's sailplane programming thread for the DX18 recently that might be helpful.
In broad terms, call your rudder Aileron, your spoilers Flaps. I set up three flight modes: Launch with motor active on throttle stick (many folks just use a switch); Cruise, with throttle stick inactive; Land, with spoilers on the throttle stick. I have a DX18, but the programming and even the files are transferrable.
Cheers,
PeteM

Wow! I wasn't prepared for 50+ pages in Duworm's thread. I suppose luckily I will have limited need for fancy mixes or mode setups. A elevator trim position or motor/elevator mix for launch, trim position for cruise and then a mix with spoilers & elevator in landing mode

Joe Nall

PilotDane,

Look for a big, red Sprinter van with MS. plates, and say hi! 3 of us will be camping, usually down by the 3D line. I actually spend more time at the main line, but better camping (before the new renovations, anyway) by the creek...whoops, river. Arrival Tuesday, departure Saturday.

We don't bring anything to fly, just relax and take it all in. And I'm not a highly experienced glider pilot, but have managed to pick up on a few things plane and heli related the last 33 years of this hobby. Not a lot of soaring activity in central MS! In fact, the ONLY soaring I
I'm familiar with goes on near Montgomery, AL 3.5 hours away at what I consider my "home" club. The field is reserved from sunup til noon Thursdays for the glider guys. But I do enjoy tossing my powered gliders when I can.

Looking forward to seeing anybody that shows up at the Nall.

Roy

I just set up my first glider with spoilers like this. works fine. L/S full down no spolier/ full up full spoiler. Nice part you can deploy them part way.

Hi,
check out this web link to a guy who does spektrum DX6~18 type TX programming. You may or may not like paying but time is valuable and this looks to be the next best value to having an expert directly help you out - it's step by step.

best wishes, john s.

I read somewhere that Sherman Knight was putting together sailplane programming guides for the DX line of transmitters. His guide for the JR9303 became the gold standard for that transmitter so I would expect his new guides will be equally well received.The link above takes you to the new programming guides he is creating. You should be able to find everything you need there.

I set up my spoilers just opposite. I fly primarily power so I put them on the throttle stick. Throttle stick down (low throttle) for fully deployed spoiler and throttle stick up (full throttle) for retracted, or no spoiler. The reason being when you pull power back you descend, stick forward you fly level/climb. So spoilers out you come down a lot faster just like reducing power.
