big thanks for the link. I remember reading about that mod. Not sure I want to risk it, but with our usual overcast skies, I need a solution for reading the upper section of the OSD. I tend to solder adjacent contacts together+re-do a lot when trying this stuff - but haven't bricked anything yet.

How do i tighten up the turn redius?

Reduce the 'Hit Distance' in the menu. I think it's default to something like 200 (meters). Make it smaller and it should circle tighter. Or do you mean, how to make the initial turn to home tighter? I think that may be adjustable, but can't recall right off the top of my head...perhaps turning up the ROTstep gain...

Increase ROTStepGain. Do so in small increments.

Attitude Limit will determine the roll rate for you i think...could be wrong mind

Max heading change? if its higher it would change the roll rate according to manual

Hey guys, I really can use some help. I have a DOSD+V1 with software version 4.0. I bought this when it first came out, but never used it until now. I plan to use it in a Stryker, but there is no elevonmix for this version of software.

I have tried for about a week to get the pc commander to work using the flytron usb/ttl loader and this one (http://www.foxtechfpv.com/index.php?..._image&pID=242) but no luck. I can use hyper terminal and the flytron loader to communicate with the DOSD. I also tried the ds 30 loader, but when I select the hex file the write config box on advanced tag and the write program on basic tab become unchecked and grayed out. When I click download, the download box opens and says "Nothing to do"

I hope you guys have some insight on what the problem is.

Thanks
Hocke57.

No, that only works if you have an IMU installed. The DOSD itself can't determine bank angles without an IMU's input.

hey john,

how are ya? just wandering if i can get another standard 5 pin plug that goes from dragonlink tx to back of futaba radio, I filled the wire end connector with solder and could not melt it out...uggh....let me know, thank you...joe janis

I think the baud rate for connections changed around then sometime, don't know it that helps?
can you try loading older/newer versions incrementally ?

I have tried older and newer versions after the baud rate changed, and it hasn't helped.

I am currently in the middle of a new build (Zephyr II Wing) and am laying out the wiring schematic. I am running both servos on the DOSD as well as the throttle signal wire for AP to control the throttle. My question is; where does the power come from to power the servos while they are connected to the DOSD? Does it come from the CH9 PPM out/ power cable from the DL Rx, or does it come from the DOSD? Do I still need a BEC on the DL Rx if no servos are connected to it? I am wondering where (if at all) I need to use the external BEC.

I gave away my last one trying to help another Dragon Link user but you can give this guy a try.

are you getting live data or any kind of connection with PC commander?

you need to power the servos connected to DOSD, the receiver and any servos attached to it.

normally you power one and the other is connected electrically via the PPM line thus powering the other

with a BEC in your ESC this is normally powering your system via the ESC control cable. Safer to use a separate BEC connected to a free servo position and tie back the power leads (both + and -) in the ESC control cable

DOSD does not supply power to servos.
