I crashed the other day with the apm on board and so I have moved to a new plane, (the original plane was a cessna sykartec, the new one is a 40 size trainer converted to electric)The new plane when switched to stabilize mode pitches up to full vertical and does not stay any where near level, we have checked different levels when first starting the apm unit but get the same action each time.My question is, do you have to calibrate the apm unit and transmitter settings each time I start a days…See More

Great to hear you got the APM going :) - pity about the cessna's wings giving way. :(
Looking forward to seeing Richies UAV and Flightbox going soon!..

Richard Unwin commented on Richard Unwin's blog post Autopilot Success - I Am Stoked :)"Tom, the cessna did not come with a spare, my first one did and the wing was alot stronger ( I had a midair with a light pole with it and the wing only dented), this last one had no wing spare and looking back i should have added one and not relied…"
Tom in ON commented on Richard Unwin's blog post Autopilot Success - I Am Stoked :)"Richie,
Sorry, but was asking about the Cessna, that's what I also have. Mine has a fiberglass rod in the wing and wonder if it still would end up broke such as yours in the picture. Thank you.
Tom"
Richard Unwin commented on Richard Unwin's blog post Autopilot Success - I Am Stoked :)"Tom, i take it you are asking about the intact uav and not the cessna, there are two fibre glass wind rods that run through brss tubes in the fuse and in the wings with the rods supported by plywood end plates and braces setinto the foam wings, the…"
Richard Unwin commented on Richard Unwin's blog post Autopilot Success - I Am Stoked :)"Simon s, the cessna is a skyartec form hobbyking ( and is my 2nd one ) they are a great plane once setup right, although this last one HK decided to go cheap and leave out the wing spar and rely on the wing struts to hold the wing together.

Tom in ON commented on Richard Unwin's blog post Autopilot Success - I Am Stoked :)"@ 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.

Simon commented on Richard Unwin's blog post Autopilot Success - I Am Stoked :)"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…"
Simon Amstel commented on Richard Unwin's blog post Autopilot Success - I Am Stoked :)"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!"
Richard Unwin commented on Richard Unwin's blog post Autopilot Success - I Am Stoked :)"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."

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…

This is taking longer than i thought but happy with progress in the last two weeks or so. I got the wing cores cut (by Glenn at OfftheEdge)and proceeded to wing bag the centre section. This was a disaster as i tried to get too fancy and mylar the top which resulted in a very heavy section, I have since decided to mount the wing either side of the fuse and reduce the wing span by 350mm.
So i have now mounted the wings either side of the fuse snd will proceed with the design from… Continue

warren, yes David at Bask Aerospace sent out a new complete autopilot and this one worked, I will ask him if he found a hardware issue with the first one as it would be good to know what was the fault it case it happens again.
