What you can do is increase #define MAXTHROTTLE to 2000. 1850 default value is low and you will get a boost if you up it to 2000. If thats not enough just go back to the old speedies. You can still get good results with non-flashed speedies you just have to fine tune the copter a bit more.
Thanks for the ideas. I already tried uping max throttle to 2000. No change. I have heard that the HK super simple can handle the refresh rate of the Quadrino,anyone else hear this?

Leave some room for ESC's when full throttle. Set to 1950.

With the Crius aiop v2.0 on multiwii 2.2, do I have to change the baud rate for my rctimer ubox gps v2.0 by using ucenter software or it will automatically be able to talk to the crius board which is new on multuwii 2.2. ? I would like to confirm on that. Thanks

No need the code already takes that into account using the max throttle.
That is why is good to have it match the max of the radio.

Well it's too quiet here again.

Let's make a survey.

Please post your average flight time, quad size, lipo and KV using only MultiWii

<10min
450mm
2800mah
1130kv w/ 10x45

Nice... but i think the AUW is the decisive factor for the flight time.

What should I do?

I have in config set:

#define QUADX
#define I2C_SPEED 400000L
#define MEGA
(tried all these for alternative values - nothing changed)

no board or sensor defined
There is a new dynamic vibration test version out now, a little bit different, but working.

Thanks to PatrikE who made it.

Can someone explain what Pos, PosR and NavR is? I searched all 1000+ posts in this massive thread to no avail. And Google wasn't helpful at all. Or even MultiWii's site. It's almost as if it's common knowledge, but apparently not common for me.

Thanks.

Thanks. Ok, that document didn't really explain what they are. Perhaps it's outdated?

Pos, PosR and NavR.

Pos = Position Hold?
PosR = Position Hold Rate?
NavR = Navigation Rate? = RTH Rate as in document. I think I get it...

You are right... i'M just looking to extend my flight time. That's one thing I hate about copters vs plane.

I get 16 minutes on my modified X525. I removed the landing gear and use cable ties to hold the motors on. I use dt750's and 9x4.7 gemfans with a compact zippy 3700 3s 25c battery. if I add a gopro I get massive vibrations and much lower flight time. Its always a tradeoff but with the right combination and a light frame you should be able to maximise your flight time.

You can see my x525 near the start of this video (approx 1min 30sec) I took the other day at casey fields in Melbourne. It flies like a little rocket, powered by home made multiwii.

I'M using the Keda 20-26M 1130Kv with 10x4.5 props on a 450mm at little less than 1kg (with FPV stuff, etc).

With Zippy 2200mah 40c and I'm killing them... They are getting puffy and do not hold a charge.


What's wrong? I thought that Zippy was a good brand. So I'm thinking of changing my motors...
