I have just bought the ArduPilot Mega 2560 Full Kit... plus the Triple Axis Magnetometer HMC5883L. I should have it built over the weekend.. then i'm off to a my mates machine shop, and i'll make the splitter plate for the lower frame onto which i am going to fit the Ardupilot. the magnetometer i'll put on the tail as suggested. I am going to use my X-cell Razor 600E. For those that dont know its around the 50 size nitro heli.
Do i need to buy any other sensors i.e. the Sonar... i can fly a helicopter all day long but this is my first time flying one with stabilisation so any tips would be gratefully appreciated.
If this works well then i am going to try and use it on my x-cell gasser. i can get up to 20 minute flights with this. But i think for the time being a battery 600 is the way to go.
i'll post some pictures when i have it all together.
thats funny, we get the same service here too :)
Oh yeah? I can't believe that any company could be as incompetent as Bell Canada. I honestly don't know how they stay in business. Well, I do know how. Their billing department always makes mistakes in their favour, but NEVER in the favour of the customer. And if you aren't paying attention, they just pocket the money. Even when you do notice, they often keep your money anyway. They still owe me $20, but I'm just walking away at this point.
That really made me laugh :D
sorry to hear that they got away with $20.
No, I have not used the latest on GIT. I'm waiting to see how that shakes out as there's been a lot of big changes happening lately. I'm still flying with 2.4.1.
And I should say that I just put the changes for H1 swash plate into trunk, which broke the MP usability until Michael Oborne makes some changes to it. I believe the only effect is that the setup screen doesn't work. CLI and doing things manually on the parameters screen should work. But none of this matters if you wait to pull GIT until MP is updated.
I'll wait until it all gets tested.....before i load it. although they are saying even in the version i'm using there is a DCM error that can build up. May wait until the release is on MP.
Yes, but that has existed for a long time, and if it hasn't caused you trouble, it's unlikely to. But right now what's in GIT is fairly experimental. It is looking great though! But I just like the quad guys to be the alpha testers. ;)
Oh no, shingles coming off the house across the street!
I can actually hear my house shifting a bit with the wind gusts. It's a crap modern built house. I miss my old house, it was built much better. 2x6 exterior walls with 1/2" plywood sheathing all around. Bomb-proof.
Is that your shed/garage? !! that sucks.....
No, thank goodness. I built my shed myself. It's built like a brick $&%%house. If ever there's a tornado, we'll leave the house and take shelter in the shed! :D
Man, had a not great day today. No, I've got all my shingles and the shed is fine. ;) But I pretty much spent most of the day installing those new servos. It was tougher than I thought because somehow I missed the fact that they were too deep on the bottom to fit in the frame of the HK600GT. So I had to machine up some stand-offs for it. I had to take much of the heli apart to get them in. But, I got them in and did a beautiful job on the wiring. The servos are pretty nice and sound WAY smoother than my old ones when I drive them with a servo controller.
Connected it all up, 2S direct to the servos, with a 3S battery to power the APM through the L7805 regulator. The servos worked but they were a bit twitchy. I realized that the two circuits did not have any common ground! I'm actually surpised that they worked at all! Pulled apart my breakout board and rectified that so there is now a linkage across the ground. Put it back together and tested it.... one of the new servos is dead! I don't know what happened. I can only guess that because there was no ground path for the signal, that something happened. I took it all apart looking for a problem, but, no dice. It's scrap. The motor works still if you hotwire it, but the IC must be dead.
To make matters worse, HK is out of stock on them so I can't even order a new one!!! Goodness knows when they'll get more. :(
My only option at this point is to go back to my old slow servos. Or, I'll take the 0.03 second one off the tail, and put it on the swash to replace the dead 0.06. I realize this is normally a no-no, but since they're so fast, I think even the slower ones can move faster than the APM anyway! You can't really even see them move they're so fast. I really don't see a problem. Nothing will be happening terribly fast anyway with the APM. Plus it can self-stabilize if one of them moves faster than the other. I'll check it out in any case to see if there is a problem. And I'll leave the flybar on until it's sorted.
If I was really brave I could just take the gears out of the dead servo and put them in the fast one. I bet that's the only difference...
Was just looking at the wiki and the reg can take 7-11 volt, you not worried that a fully charged 3S lipo will damage the board? I also dont know many fast tail servos that take 7.4 volt.
You could use one big 2S lipo to power everything. Think it might make you life a lot easier.
I'm sure you know what your doing.
On a brighter point. Glad you are your family are still with a house and shed. :)
I'm going to have a look at HV servos, see what others are about. I think futaba make an HV tail servo.
