Hi, no that was a GoPro Hero2 on the pan servo. I have just installed the latest firmware and it seems to be working well, I've reduced the FOV to Medium to reduce the fisheyed effect to at least bearable. The camera pointing down is a Mobius with WDR on and some custom settings. Although there is some jello in the Mobius I really,really rate this camera, bang for buck it can't be beat! Same goes for DragonLink too ;-)

Increase your video signal level, longer range, less noise.
Greatly reduce the Drag on your plane, increasing battery life and increasing plane speed.
Make your plane lighter.
Reduce the size of plane for transport, and reduce change of damage to both antenna and video transmitter in a bad landing.
Circular polarization is great for 5.8 GHZ where multipathing is a big concern. At 1.2 GHZ, you are better off with vertical polarization, which gives a noticeably stronger signal.
Mike, a couple questions about the Dipole Video Transmitter Antenna.

1) what is the best orientation for the antenna? vertical? can it lay down against the wing surface?
2) can this be used with an IBCrazy pepperbox antenna on the receiver side at long range?

The dipole antenna must always be VERTICAL.

Yes, you can use it with the pepperbox antenna. You will lose a little range since its not vertical polarized, but not to much..

When all else fails, blame the elevator servo...

DragonLink LRS - $268

Complete FPV Aircraft
and Ground Station - $3097

Having your Elevator Servo Fail
during pre-flight checks instead of
10 minutes into your first flight
of the day - Priceless...


Above: This morning at 5:45 am PST, doing preflight checks on the old trusty Skywalker.

After waking up at 4:30 in the morning, I was out at the field doing preflight checks.
I hadn't flown at all in the last 6 weeks. Got everything set up and powered up.
Cameras all on and running. Systems check. Throttle check. Control surfaces
check. When I got to the elevator I cycled up, down, up, down, up, down, up, then
it FROZE! Nothing. Nada.

Powered down and restarted. Nothing! Packed it all up and went home
as the sun was coming up over the horizon in the East.

Diagnosis:
The problem was not my autopilot, my Taranis, or the DragonLink. It was simply
a servo failure after about 700 flights. Damn thing just up and quit!

I call that a VERY successful FPV mission, even though not a single flight was undertaken!

What up, DL,

I'm curious about component separation, effects of UHF noise on the system from other components, etc., as I am currently troubleshooting some range/RSSI issues with my system (don't wanna get into that yet, still running some tests on my end).

I'm running a V2 system with updated next gen firmware. My DL Antenna is out on the wing tip in my Penguin, vTX on the other. I run the 36" extension from antenna back to the RX in the fuse, where it is in proximity to the Vector PSU, Pololu 12v step up reg, low noise RMRC 5A BEC, pz420 and a GoPro. Despite the antenna being in its own climate, essentially, out on the wing tip, could the RX be getting effed with back in the fuse by all the other gear? Is the RX itself vulnerable to UHF RFE by associated Gear?

Posted back in FPVLab as well.

Thanks.

May we ask, what brand servo failed in the elevator?

The Dragon Link system is incredibly resistant to noise and RFI. We sell thousands of these sysetms, and they just work, for beginners, advanced, you name it, stick it I a plane, and it just works 99 % of the time. No special measures needed... Even on copters, where everything is right next to each other, it works. So your plane SHOULD be easy.

So my first question is, how do you know you have bad range ???

When did your system ship , and who did you purchase it from ???

I need to make sure you really do have the next generation firmware, instead of just thinking you might have gotten a successful update...

Last: Pololu 12v step up reg !!!!! ???? Why would you have that in your plane ? My experience with step up regulators is that they are HORRIBLY noisy This may or may not be a problem, but it sure gets my attention . And it should not be needed either... I bet I come up with a better solution once you tell me why its there.

WOW !!! I am so glad you found it. That plane has lived through to much to be taken out now.... And yes, servos do fail too often, so here is what I do to lessen the risk.

I ALWAYS use expensive JR servos, The good ones, not the cheap sport models.

On my larger planes, EVERY control has two separate movable surfaces, and two seperate servos. This way, the plane is still flyable no matter which servo fails, or comes unplugged
