MegapirateNG 2.9 R300 issues

[Allanm]

Yes, I took the plate out last week. I have only had this issue with the plate out, but then again, I had never used Loiter before.

One scary thing I have noticed with 283.....

I tried a quick test flight in my garden with 283. I only tried a hover and moved around a couple of feet. It all seemed very stable and I only used stab mode.
I landed the quad and shut off the motors but forgot to disarm. I had one hand on the quad and turned the TX off. Failsafe activated!  .

OK, I know, I should have disarmed the quad first or disconnected the power before turning off the TX, but with 29r300, once the motors are shut down but not disarmed, i can turn off the TX and nothing will happen.

Good job I had my hand on it.......

Still too windy to fly. This is why Kite surfing is very popular here.....

From the pictures I`ve seen of accident with multirotors , it`s a Good job you still have a hand to hold it !!!!

[Allanm]

Mmm. Nice sharp carbon fibre props too......

.Mike, I have a Multiwii Pro V2 board fitted ( Which I assume is the same as the Crius) Where would I get the Multiwii firmware and which is the most recent stable version?

this is the links to multi wii
in saying that they do not have the issues mega pirate is having but you have to relearn a different interface but then thats all part of the fun lol
on a side note
my frame was a 450 flamewheel clone 4 in 1 esc on bottom plate and control board mounted on 12mm posts on top frame well clear of anything and no metal plates or anything like that to cause interference to compass

You can find a copy of the latest multi wii v2.2 already set up for the AIOP here http://www.multi-rotor.co.uk/index.php?topic=1762.0

No one has made any changes to Mpng for over a month now. I reckon it';s dead unfortunately unless someone takes over the mantel

[Allanm]

Thats a shame, forgetting dropping out of the sky the first time I used Loiter, my quad was very stable and worked great.
Oh well, I am using 283 now and that seems ok on a quick test.
Still lusting over a Naza FC and GPS though......

Allan

[peter_a]

Does multi wii need it`s gps via i2c or can it be with serial on the AIO board ?

[Peter]

Can be done serial. Same connection. The stable 2.2 has RTL, but stays at same height. There is a fork with proper RTL and failsave. I didn';t test it, using 2.2 for fpv with rush osd on minim odd hardware. I tested 2.8.3 mpng, but could not get it stable. Multiwii stable out of the box. Only some tuning for stable descent.

I';ve just spent the whole afternoon in the garden tweaking my megaP 2.9 r6. I flew about 10 lipo packs and performed several 360 degree yaws whilst loitering with no issues at all.

[Allanm]

I wish mine did that... I used about 4 lipos testing Loiter ( and other modes ) without props after moving the board and recalibating everything I could. First flight out and it dropped as soon as I started to turn CW whilst in Loiter.

283 is ok, but it isnt as rock solid in the wind as r300 was, it tends to drift about more and I dont get the same feeling of confidence. On the plus side, it hasnt disarmed at all, so, thats got to be good.
Allan

[robshaw]

Are you on r6?

[Allanm]

I';m using 2.8r3
I originally had 2.9r6 which seemed fine, but I dont ever recall using loiter. I upgraded to 2.9r300 after people with r6 reported disarming mid-flight.
First time I tried Loiter ever was with r300 and it disarmed. I have been able to recreate it occasionally on the desk and a couple of days ago when flying, though, thankfully only a metre up over soft grass.
2.8r3 seems very stable so far, but its too windy here to do further testing.
As soon as the wind drops I';ll take a few lipos out with me and go through all the modes.
Shame, I really liked r300.

[Allanm]

Well, after an afternoon of loading and reloading software, I have a nice stable quad now, though, unfortunately not flying 2.9.
I reinstalled 2.9r300 and reinstalled all the params. First few flights were fine using all modes and I thought I had cracked it. Then, suddenly while in Loiter again, it disarmed. Again, I was only a few feet up and it landed safely ( this Trex 600 landing gear is very bouncy).
So back to the drawing board and I reloaded 283, levelled , declination set, esc';s recalibrated, all flight modes reset and loaded, radio calibrated and as the wind has eventually dropped, took it for a few flights where it behaved impeccably.

I really hope someone comes along to further develop 2.9, it has some great features, but for now, I will stick with 283.

I am also building a new 550 size hex, so I can safely sell my quad to help fund it, now I know it flies perfectly.

thats why i went to multiwii,i read too many probs for my liking
i wanna fly the thing not worry its going to drop out the sky.
then fix the damn thing,then something else goes wrong..
not worried about waypoints etc,i can do that with android app (ezgui)for multiwii if i need it..
thats my two pennies anyway.. ::)

[bulesz]

...this Trex 600 landing gear is very bouncy....

yééé, the TREX 600 landing skids are very nice! I';m using them for my F330 with success.

[firey1]

yes i do like the 600 skids as well nice strong and not too heavy and gives me good clearance for battery

This looks interesting.

I might give this a try myself but I took out my Crius v2 with MultiiWii today, it has to be said it flew brilliantly ... much "better" than Megapirate 2.8.3 or 2.9.1r300 without any tuning, more stable, less twitch, almost no trim needed unlike MegaPirateNG.

The thing I couldn';t get working is RTH or POS Hold - The thing was all over the place.

[peter_a]

I`ve flattened my battery testing it out, and it`s much better for me.
It`s the first time i`ve had a couple of seconds with hands free hover on stabalise , I`ve mount the board on felt pads and foam double sided tape , so may have cut down the vibrations too , but may have made some new ones with the wind crashing me into the washing line pole which as chipped the prop a little , hope it`s not bent the shift with the drop on a motor .

[Allanm]

Just when I had it flying nicely on 28r3.....
Mike, let me know how you get on with it, if it stops the thing turning into a gravity experiment, I will try the new software...

Hi Allan
I have uploaded it last night and will try it out tonight and see how it goes and keep you posted on results

[robshaw]

Ive still not had a problem with 2.9 r6, flew 3 packs today on Southend beach today... But all these stories about dropping out the sky have made me nervous so I will also have a go at this new version. Probs stick it on tonight for some flying tomorrow.

Thanks for the file you sent Rob but i couldnt get it to load for some reason when i try i keep getting a failed connection even when i tried doing peters file through mission planner i got the same results  so downloaded the original file from the wiki page and uploaded through ardunio and all worked

[robshaw]

Thats weird.  Ive uploaded it to my board a few times now with no issues.  Have you uploaded Peters modified file yet?

[firey1]

yeah tried that as well and wouldnt work either not sure if its a prob with my board or mission planner
followed petes steps from his video but would always fail on connection to board

[robshaw]

Thats strange.  I got my first quad from peter and so the crius board im using at the moment is from him but i also have another one which I flashed with peters file and it worked ok.  Is yours a v2 (not that it should matter)?
