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.
I will try using the sonar as-is with a plate to angle it and the sonar the same angle as the APM to at least not have a default ~10 degree tilt in the mix by mounting it parallel to the bottom of the heli.
Gotta spend less time reading and more time playing, haven't even taken the 2.5 out of its antistatic bag yet :-)
Well guys tomorrow I will join the test group. The APM 2.5 will finally arrive. I'm excited to play with this thing and hope I don't have build a quad to use it. Its going on a Raptor 50 that is tuned perfectly with no servo trims and will hover in one place with no input for about 20 seconds. So off to the races. From what I'm reading, i should not use 2.7.1, correct?
I don't know that there is a problem in 2.7.1 as *I* am flying it without issue... but, it seems that I am the only one?
P.s. I think you will have less issues starting with a well tuned heli, that is the next goal for me once I move over from the 2.0 to the 2.5 (hopefully this weekend). I just need to sort out how exactly to bypass the stabilization and use just the CCPM mixer as this is a function in the APM, not the radio now. My 600 is flybarless though, so I don't expect to have a 20 second run with no input though, very impressive. I never seem to have that little wind where I am :-) I've always been curious how it will fly with no assistance.
Malcolm, yes, this is something that I have suspected. When I first discovered the effect of Iterm and how I needed to Zero it, I questioned whether maybe it was a difference between Flybarred and FBL. I suspect it could very well be true that flybarred helis need zero I term, and FBL needs non-zero.
You won't be able to do quite what I showed you with my Acro mode hack. I created a special "leaky integrator" in that code, which is not in 2.7.1 yet. I thought about pushing it, I think it's fairly straight forward, but since it hasn't been flown much... I did fly it a bit, but not a lot because of the problems with my 450.
Hi every one!
I have a little question .
Did you keep your gyro on your helicopter or you just use the apm gyro ?
I 've bought a TREX250 and there isn't many place in.
So if i can fly without my crappy gyro ( assan ga 250 ) i will be happy ^^
So you made some flight without your external gyro?
You have a FBL system isn't it ?
Is it a problem if i have a fly bar system ?
Can you give me your pid seting ?
I have some problems to with my tail prop.... but the faut of my problem is maybe the servo tail...
it's not a brand news copter. I bought my trex with cheap gyro and ultra cheap servo...
No need for an FBL system if you're using arducopter.
Flybar system is ok, but it'll cause you trouble when it comes to doing loiter i believe. That's my experience with the trex450 anyway.
When it comes to the pid settings..it's the rate settings that you should concentrate on. I.e. Rate Roll, Rate Pitch, Rate Yaw. I don't have my settings around at the moment but you can tune them in the air using channel 6. My guess is they will be close to the 450s.
Randy, Rate? Did something change? Used to be Rate did nothing, and Stab was the thing to use.
Sorry, Robert's right of course. I've been spending too much time in multicopter-land where rate is the thing to tune. In the helicopter it's stab roll and stab pitch. If you're using an external gyro for yaw it's stab yaw...if you have no external gyro then you should tune rate yaw.
Tahnks a lots both ^^
I try this when it will be ok...
I broke the landing gear yesterday :/
Luckly, i just broke the landing gear lol those thing fall very faster with the nagative pitch lol
