Hi,
Since Marschy did such a good job of showing us where he's up to, he inspired me to do the same.
So this is my tricopter:
![](http://gallery.myswag.org/gallery/d/48996-2/20140817_211152+_1280x720_.jpg)
It consists of 7mm ply wood for the plates and 12mm x 12mm pine for three booms. I'm using the DT750 motors with 10x4.5 props. Seems to have plenty of power. It's based upon the rcexplorer.se tricopter (v2.5)
I typically power it using a 3s 2200mah battery but I also use 3s 5000mah for when I want a longer flight time. On the KK2 board I was getting 12 - 14 mins on the 2200 and about 20-22 mins on the 5000. Now that I'm using the HKPilot 2.7 board I'm expecting this to go down as I'm now powering my camera and OSD through the main battery, and the APM board I think will be a bit more hungry (I have telemetry and GPS that my KK2 config didnt have). Those times were with an action cam mounted on the front instead of the PilotHD. I am building my Go Pro mount this week and plan to mount it onto the frame.
Can you spot the minumOSD tucked away:

It's tucked away with the custom harness I made. Hoping it will work when I get my replacement camera this week.
My radio and monitor:

I've just got a basic Turnigy 9x (running stock firmware), I plan to upgrade to the 9XR soon.

My telemetry on PC (use my phone or tab when out and about):

This was one part that was easy for the PC, took 30 mins to work out how to hook up to the Android tablet.
Now that I've got every thing working (minus the camera) I'm hoping that I'll get a break one of the days before work this week and give it a test flight. The KK2 board worked well and I can switch back to it easily as the tray on top can be swapped for the KK2. Really looking forward to testing out this APM board. It looked so graceful on the last test flight, until the failsafe kicked in.
I cant say it enough, this gear is not plug and play..... Just about everything needed some tweaking. The only part that was really plug and play was the power module. I've had to switch wires for the external compass, I've had to cut the GPS from 6 pins to 5 pins and I've had to move wires on the OSD telemtry piggy back cable.
I've also built a custom harness for the MinimOSD to work.
I need to feel confident that it will fly how I want so I can take it to Fraser with me in the next couple of weeks.
One of the mainstream providers would do so well like HK if they did this for you, even if you buy the kits you still need to tweak this stuff, absolutely crazy. If you didn't have basic electronics skills you'd be stuffed, you'd give up.
