How to radio set-up for a DLG w/ ailerons

Hi guy's

I put together a DLG with ailerons, and would like to know how to set the radio. I have it set up regular (for planes) elevator/ailerons on the right stick and rudder on the left stick. I have the ailerons/flaps set on the right toggle to move down about 30 degrees.

I have not mixed anything yet, not sure what is considered normal for DLG. I got the plane because I thought it would be cool to try, and have never seen/talked to anyone who flew one.

I have thrown it a couple times (easy tosses) I think I need to mix a lot of rudder to the right stick. Maybe more rudder than aileron, but I am not sure. So any tips would be helpful.
How do most set their DLG for competition?

Thanks
Ron

I'm still getting my radio programming all set up on my own DLG (Supergee II with a Futaba 9C), so I might have a little insight after I get mine all figured out. It might be helpful to others if you let people know what type of plane you've got as well as the transmitter make and model.

I also noticed that you're from Rancho...I'm just a few miles away from you and actually work in Rancho. We'll have to meet up to toss our airplanes around sometime. Drop me a PM if you'd like to fly sometime.

My plane is a "Li'l Breeze" from Hobby Club. It has gws pico servos in the wing and JR241's in the pod...My radio is a JR XP6102.

I work in Claremont at the High School (construction remodel), is there a local area to fly/toss??

Thanks
Ron

Brain, the 9C is like, so damn easy to program. If you need help, I'll give you info on setting up the radio. Basically, I got the controls as usuall. Dual rates on either switches, Airbrake on/off switch on the left to control the flaps with the throttle, Camber control on the left slider.

let me know and i'll help out.

sorry ron but I have no idea what channel assignment is on the JR radio. If you can look in the manual and look at Flaperon settings, you should pick it up from there.

Nah, I'm not having problems setting it up. Just finally got all my servos in and everything working. I'm just trying to figure out the most comfortable way to do things.

Thanks for the offer though Tomi.

Hi Rocket,

I would start with mixing the rudder to ailerons at 50% rudder to 100% ailerons for starters and see how the model handles. If the nose points into the turn too much, remove some of the mix. If it still looks like it wants to point away before the turn-in, then add more. Make sure you are using aileron differential, otherwise you will get a lot of adverse yaw with the downward moving aileron and that will negate the rudder mix. Use about 1/2 as much down aileron as up. (Like 1/2 inch up and 1/4 inch down).

I don't know about the JR 6102 capabilities, but if you can, set up some camber by programming about 1/16th inch down on the trailing edge for your camber mode. Reflex mode is about the same amount moving upward. I don't know what you prefer on launch, but if you prefer to have the nose rotate on command when launching then set up the trainer switch to add a touch of up elevator when activated for launch mode. My models are set to rotate automatically on the launch, so I don't use a launch mode. My flaps are set to drop about 45 degrees with elevator compensation, and is quite effective. (Your mailage may vary).

I think the most important part of this set-up is the aileron differential. If you don't get this right, the model won't roll or turn correctly and smoothly.

For my Blaster I use the following setup -
Ailerons are on channels 2 and 5 I believe (I have an 8103). You'll want more up aileron travel than down travel. You can set this with the differential option in the radio 50% differential is a decent starting point...but you'll have to get out and fly to get it setup. You shouldn't need that much rudder mixed into the ailerons if you get your differential right. It sounds like you need less down than you currently have it the plane isn't wanting to go into the turn.

Ailerons and elevator are on the right stick. Rudder on the left as well as camber. Top of the left stick is no camber or reflex depending upon how you set it up. Bottom of the left stick is thermal camber and I have a switch that changes the camber settings to allow for a landing mode.

Pretty simple setup. But it works good for me. I don't have to worry about getting sliders centered when I'm going for a quick turn around...just push the throttle stick to the top, grab the tip and fling her I just use the one switch for changing flight modes...but I can put it in landing mode and still have thermal camber...I just have to watch where I position the throttle stick. In my mind it's best to keep things simple and worry about flying the plane rather than what to do with your radio.

Good job on joining the JR side you won't be sorry! There is a "manual" that goes over some VERY advanced programming of the 6102 and 8103 but I can't remember where to find it...it's a little more advanced than what you need for a DLG...

Good point about the launch mode...

A properly setup aileron model shouldn't need one. You can effectively adjust the launch angle by adding/removing nose weight...but this really isn't the best way to do it since it will also affect your glide path. If you add weight you'll need more up trim on the elevator to keep the plane level...which will result in a steaper climb out angle and will probably even tend to invert at the apex and roll over you. Removing weight will flatten the launch angle b/c there will be down trim in the elevator...be careful with this one! This is also a way to find a good CG for the model...but not the "best" one out there! Be careful when removing weight from the front and adding down elevator!!! Too much down trim and POOF...not cool

Any preset is added drag on the launch, so try and minimize it if possible. My Blaster comes out clean and holds the angle that I toss it out at. It took a couple of days of tweaking to get it just right...but now I can toss her to 130-140ft.

Thanks everyone

I will read, reread, and then read again what everyone has written to figure out what it all means, After first go through I am gonna use the left stick up and down to control something, need to research camber and reflex. After 22 years of racing RC cars I know how to set up camber and what it does but I haven't thrown my car in a while I will search the forums to figure it out

Again thanks

Ron

Hi mlee8249,

I am also in the same boat as far as setting my dlg up. When do you use cambe and reflex?

Hi Oscar,

Camber and reflex: Camber is used to increase the undercamber of the airfoil and this allows the plane to float better in dead air. If I figure that I don't have to motivate across the field to get to some lift and just need hang time, I camber the wing. In very light lift, I may also camber the wing. This is the type of lift where the model just barely maintains the altitude and without the camber, probably will not maintian. In good lift, I normally just fly without camber, using up more speed to increase lift from the wing and accelerate through the thermal for best climb. Now, this is my method and not everybody else's. Many pilots leave the camber on while thermalling to increase their chance of accelerating upwards. I like going faster. But for pure hang time, like when the sun is dropping down out of sight at the end of the day, I camber the wing. On my XP-4, the camber is on more often than not. You would think that as little as 1/16th inch trailing edge camber wouldn't do much, but once you see it in the air, it's pretty obvious.

Reflex is used to get the wing to fly faster in the cruise, such as when you spot lift on the other side of the field and need to get there in a hurry, or when you need to penetrate upwind. It doesn't always work on all airfoils, like the RG-15. Reflex on the RG really only adds drag, and the airfoil is already a fast one anyway. Just point the nose down a hair and off you go. I don't use reflex very often at all as the Drela airfoils on the XP-4 are fast when you need them to be and from what I hear, just having the top surface in the natural state is considered reflexed. Hope that helps you out.

well i think i have the radio set up for the first real launch this weekend

I set aileron differential at 50% (to start) I will adjust as needed.
I set camber on the left stick (throttle) up stick is O% camber and down stick is 1/16th inch to 3/32nds inch. I did not set any reflex (I figured I would try it first before I set any)
I set flap toggle to about 40 degrees down.
I mixed 50% rudder to ailerons.
Not sure the weight yet but the CG is aprox 3/8th inch behind the suggested mark. (it test flew ok but will try to get it to the recommended mark)

Averen
I have been using there Car transmitter for quite awhile (and very happy) so the plane was a natural choice (very happy with the 6102) well I guess I wish it was a 6302 (30 models) since I have between 12 to 15 planes fitted for flying at one time.

Well wish me luck
Ron

Ron -
That's quite a lot of planes!

If it's possible have the aileron->rudder mix on a switch...I don't fly with it at all...it I feel it needs it I manually add it in. It will make you a better flyer if you can do it manually and have the switch for when you need it. The main reason is b/c when enter a thermal turn you'll want mainly ailerons...then you'll add a little rudder and back off the ailerons...then to exit the turn you'll start ailerons and less rudder...Dr. Drela posted an article about this...I'll try to find it.

50% is quite a bit! The MAX i've ever used was 25% and the plane wanted to fall out of a turn b/c of it.

Good Luck!
Jared
