I have a issue maybe someone has seen...Jeti ds24 gyro on a three position switch...i am getting the correct LED colors ...solid red, flashing red and blue / red.
when i have the solid red LED everything works great

when i switch to trainer mode and do any control inputs the elevator & ailerons really jump around, a lot ...no wat it could fly in that mode...

i did have to reverse the ail & elev. in the radio to get them to the corrected throw.......i tried switching the wires on the board but no luck..

input??

[Mud Duck]

Got the LED landing lights all hooked up and wired in...

I have all of the items I need to try to get this accomplished too. Do you have any other installation photos / videos of your procedure? Looks awesome and surprised they didn’t include this in the model. I’m also going to add the refueling guidance lights to the top.

GG, yes to fin (for now).

You always put an amazing number of flights in. Any gear issues yet? Seem to be a probable weak area to me.

I am adding the 8mm of up trim for the elevators to the latest rendition to the manual. What about the ailerons? I thought I read somewhere 4mm of up trim, is this correct? Appreciate any help.

This is a excellent video on the set up.

Great thank you!

[Gravythe clown]

That's where I ended up. 8mm on inboard and 4mm on outboard.

Is your red light solid on the gyro? Other than that, you might try unplugging and re-plugging each connector. Maybe something isn't making contact. Check that each of the "single wire' connectors is connecting the single wire to the signal side of the RX. ignore the color of the single wire connectors.

You know I didn't even check the red light on the gyro. I certainly will do that next time I fire her up. The 'single wire' connectors are in their proper places. The polarity of the Admiral RX is clear, and I made sure all of those connectors were accurate. Could be a gyro setting thing or one of the leads on the control board/gyro is a little loose. I'll be sure to go through it thoroughly next chance I get. Thanks for the info!

Hey Gravy,

When flying LONG wing full scale sailplanes, one must also lead with the rudder. With the ailerons being 40 feet or more away from the fuselage, the adverse yaw is huge. Yanking and banking into a tight thermal turn from level cruise….leading with rudder is the only way of even sorta keeping the yaw string centered as you roll into the bank.

Your leading with rudder makes sense…especially without the clear vertical fin.

Evan, are you using the fin?

[GliderGuy]

Gliderguy Not sure if you used the vertical stabilizer or not (I didn’t) but mine loves rudder. In fact as I said mine flies better with rudder than without. Same thing I noticed I’m all my past B2’s. If I didn’t use rudder mine would have nose up attitude through whole bank.
also I found if I started with rudder before aileron it would banked much better.
I’m not telling anyone to use or not to use just my experience.

Gravy

I am using it. That definitely can make a difference.

Thanks for pointing that out.

Evan D, I didn’t notice if mine did the same or not, but I think I was flying my rudder stick back after completing maneuver. So I might have been correcting back. Something’s I do naturally I think because I fly helicopters allot. I can’t really tell when I fly planes after flying helicopters but I sure can when I fly helicopters after long time of planes only. Lol

I agree Gravy. The only negative on mine is after I give it left it wants to stay a little left and same for right, like a bit of stiction on a normal rudder…

It doesn’t like bumpy air but a cross wind, even 10-15, it handles surprisingly well.

Handles well with the gyro turned all the way down too.

The drag brakes work well, stall turns are easy to do.

I found the book balance point slightly nose heavy but safe.

Yep…I played it safe today. As I progress into some acrobatics, I WILL use the rudder in flight.

Good to know about the cross wind capability.

Slow flying in bumpy air seems to allow the gyro to wiggle the wing controls less.

-GG

[Evan D]

Agreed, and this has long flight times too.

After 37 B-2 flights today

My goodness! I doubt I'll fly mine that much in the whole season.

Adding a few notes to Post 622

1. Flew it in bright sunlight later in the day. If at a distance, yank and bank. If you make a shallow bank that presents a profile view, she is hard to see. Steeper banks that present the wing planform HELP!
2. After 37 B-2 flights today, I will say again KEEP IT SIMPLE….you don’t need the rudder except on take-off and on landing roll out. To each his own, but I suggest you don’t overthink it…Keep it simple. I can’t speak for crosswind landings. Don’t know. I never touched the rudder during flight….perfectly satisfactory….Note added = I am using the clear vertical fin.
3. I flew in 12 mph with stronger gusts (15 maybe). She does a great job! But she does wiggle the wing controls more. It’s really not annoying at all. And you get the comfort that the electronics are doing their job.

FINALLY...the wind stopped blowing 30 mph!

Up at sunrise to maiden with calm winds. Got in the maiden + 19 more before Easter activities.

Congratulations on your Maiden! Great write up. Thanks

Gravy same with you, nice work!

I also use Spektrum (DX9) but when I look at the aircraft type, I only see "wing: normal, tail: normal". I don't see what you see on yours. Maybe it's the same?
As for the "mode" switch, is the wire you're using plugged in the right way? It's not upside down at one end, is it? Is it actually plugged into the "MOD" port and not the "gain" port? Can confirm when you look at the "monitor" that when you flip the switch, it's actually working AUX2? Other than these points, it should be working.

I went through the entire setup from start to finish and everything is working fine. I didn't notice anything specifically that was plugged in wrong, but I must have screwed up something in the initial configuration.

Took a few hours to get radio programmed and control surfaces dialed in. I have the gyro on a 3-position switch, and it toggles correctly between the 3 modes per the manual.
