Very nice :)

Not got as far as i would have liked, done a lot of soldering and wiring, all seems to be working well so far including the OSD. Aiming to have it up in the air in a couple of weeks ;D

Pics below of work in progress, motor testing, and video feed testing. Changing and full throttle is not producing video feed noise so far on my single 4s setup.

Before you install the Tornado osd,

Have a good think of how to mount it so you can remove it easily without to much hassle.
It still early days for the firmware and they are updating the firmware quite often lately.

Eg.

I removed mine the other day to update to v1.07
Didn't get around to it, had a check to see what the firmware was like by others reporting on it.

And then found another update to v1.08
Am glad I didn't update it, reinstall it in the plane, and then found this update.

That was about a week apart.

Looks good so far.

Testing for interference is pretty pointless at that point because nothing is laid out where it is going to be or the wired routed where they are going so your results are not going to show up any problems as it is right now. The interference will not show up much anyway with the motor until it has a propeller on either, with no load on the motors its not dragging any current down the cables which is what causes the interference.

Have you got some extra wire running along the ground line on the current sensor? It looks like the two ground wires are soldered at either end of the PCB and the PCB alone may not be up to handling the current. It's good practise to either solder the ground wires right next to each other or solder some bare wire along the PCB to increase the amount of conductor between the grounds.

Hi TJ,
I had considered this and its going to be mounted right next to the hatch on the side for easy access and will only be held in place using velcro :)

I guessed this was the case which is why i said "so far" ;)

Thanks Neil, wasnt aware of this, ive got plenty of wire so doing this wont be a problem :thumbsup:

I use 3m double sided sticky pads.
4 little squares in the corners holds it well.

Just my personal choice,
But I find Velcro still allows the unit to move,
Which could interfere with the gyros with if there's any vibration.

Any other thoughts?
3m double sided pads vs Velcro.

Which is most popular.

Looking good. I hope the build continues to go well. :D

AdamG · December 16, 2014, 11:42:38 PM

Thanks for the comments and feedback :)

Tj i think i will take your advice and use some 3m tape to secure the OSD :)

Not had much spare time recently so progress report is that i have assembled my Pan/Tilt, soldered in Aileron servo extensions, made aileron Y connector, connected up all the electronics and programmed everything on my Turnigy 9XR (OSD flight modes, pan and tilt dials, pan tilt override switch, RTH failsafe) :D

With a bit of luck i might have it practically finished this weekend :cheers:

Looking good! What pan/tilt is that?

Thanks :D

Its a ready made RC pan tilt. Wanted something that could hold both the GoPro and flight cam so that my GoPro footage also includes my 'looking around' :)

Ah, cheers! I've been looking around for one for my skywalker 1680, but ended up going for a hobbyking one. Not seen much about it but hoping I can find a way to mount the board cam to it as well as you say, and get the head tracking working on my fat sharks! :)

Annoyingly I ordered from international w/h before realising they stock it in the UK, so still waiting on it.

I never spotted this when i looked on HK! i probably would have tried that first if id seen it as the one i got was quite expensive once you add servos. Although i have to say it does work really well now that its assembled. Was a bit tricky to assemble and came in laser cut templates... reminded me of airfix kits :P

Just watched a few of your skywalker vids and got me excited to have my first FPV flight :happy:

iwan_canobi · December 17, 2014, 07:26:47 PM

Yeah I was looking around for a while and when I saw that and how cheap it was I figured it was worth a punt!

Cheers! My Skywalker has been great, bought it off Blueflyer on here so all the hard work was done, I just got to enjoy it! Its currently out of action though, awaiting the APM I bought from Coyote which the wife is holding hostage till Christmas! :D

Its a great plane, you'll love it!
