OK, to explain, i finally got the autopilot sorted and installed in a test plane and all went according to plan, until the wing support failed on my manual flying back to land. what takes away the pain is that it wasn't in my full size plane, that I maidened last weekend successfully with 2 x 8 minute flights.

This was my first successful attempt at getting the APM to first stabilize and then circle RTL, it was on the 4th and now final flight that we were trying to fly to some way-points that I caused the plane to crash. lucky though the plane came down in the carpark (between the bmw and landcruiser) and the APM module seems to be intact, so bining a $60 plane was worth it.

Next stage is to get the next test plane happening before transferring to "richies UAV" ( i might have to give it a model name- maybe MARK I).

"Richies UAV" - Mark 1 in test flight mode. OK the cardboard on top looks rough, but it flew, next step is to make some covers and mount a camera.

Flight Control Box, FITPC2 - 12 Volt micro computer - running Win7Pro, with Samsung 19inch (model S19A450BW) runing on 12 Volt Dc 24AH Gel Cell, the computer uses 9 watts and the monitor about 19 Watts and is quite clear in daylight, and was the hardest thing to find that didn't use alot of power, I also looked at some 12inch screens from China but they did not have the screen definition to use as a computer monitor.

Love the story and the photos of your new setup!  A big improvement over your first plane (and not just because it's in one piece)

Richard, could you post the successful PID configuration for your Cessna? I have the same one (CESSNA 206T) and I should be ready for flight within a month or so.

Thank you.

Tom, so far i have just been using the base PID config that comes with it.

Thank you, Richard for the reply. So that' good news, it may work right out of the box for me too!  :)

Great setup for the field monitor. I am planning to build a sun shield around my 19" laptop and take that out to the field.

between the bmw and landcruiser

Close one.Phew!

Just to add i recently broke the nose of my wilga 2000.The nose was fairly weak to begin with.I used a 2 liter bottle two repair it,fits perfect.Just cut the top off one.Looks better than the original,tougher and disposable.

Reason i say is because the mounts,servos and material of the nose looks the very same as mine.

Dez, thanks for the repair ideas but its in the bin as another friend has donated a old glow plane which I will convert to electric and put the Apm into.

IF that's the same foam Cessna I had (marketed in the UK by Century) it was a *pig* to fly. I'm impressed any Autopilot could keep it in the air, I certainly struggled!

Hey, you have a great setup there!

I have a bad crash myself some time ago. The impact speed was 140 km/h and the battery hit the APM. Although APM still works (after bending the pins back where they belong) I am a bit scared that it might got damaged.

Would you guys use an APM after a hard crash again?

Cheers,

-S

@ Simon: I do not have the experience yet of crashing one, but if you do a thorough check of all parameters and readings per the setup guide, I do not see why not it wouldn't work as a new one.  After all it's all a bunch of 101010100.
