First Test


I have now preformed a first test of my octocopter with MCFC.
All the calibration was done according to Minsoo's manual.

What I noticed was that first GPS fix took approx. 10 minutes. As one should be aware of is that downloading the GPS almanac can take up to 20 minutes (worst case).

Octo seemed very stable, responded well to input.
Altitude hold worked like a charm, tested it at 1,8m and 30meter. Seemed very stable.

GPS hold position was tested and found to be pretty good, somewhat of pendulum movement within 1-2 meters. I think this probably will be solved by changing PID parameters.

RTH also worked well, with a bit of overshoot, I think this also will be solved by tweaking the PID parameters.

Also tried out carefree, also worked.
I will try to change the parameters when the wheater improves, Snow and wind in Norway!

Hey guys , i also got my MCFC board setup,first think i want so solve is wen i take of in autolevel,take of nice and steady but wen i stay of the sticks the quad just fly to the right and a little to the back, do i have to trim this out with TX?It like auto level is -1 to the right.
or do i level the quad out and recalibirate gyros and accel?

So how about the pot meters?wen does the yaw pot has effect,becasue there is also a yaw PID attitude.or how do these work together?
The pitch/roll pot meter? have no effect in auto level only acro mode right?

Then the groundstation for gps waypoints! I connect the MCFC board to the laptop and outside i get like 8-10sats, also see the quad on google maps.So i set out some spot and click write.
Disconnect the usb cable and go to the backyard, flip the 8ch switch till 3rd position and the quad turns heading my.go back hook it to the laptop and do a read waypoint and says no waypoint hhmm, what am i doing wrong here?

grtz

As for trimming, this is not necessary. Do a stick calibration according to Minsoo’s manual.
However you should ensure that the frame and board is in the same plane.
Potmeters have no effect when not in acromode. However certain settings will set the MCFC in various modes (See manual).
As for waypoints, I haven’t tested those yet.

Analog resistors on the board for tuning - strange solution for 2012 year

Or its a "Kuk style", from first KK boards?

whats an easier solution in your opinion?
are there digital resistors available?

All Multiwii/Naza/Wookong/Arducopter/etc boards have digital tuning, btw

Is seems enough for users, and its better to save/load/analyze parameters.

i know it was meant in relation to the resistor.
it wasn't meant that seriously

As an electronics engineer I rather use analog pots than digital pots for tuning.

PS: KK stands for Kaptein Kuk which translates from Norwegian into english as Captain Dick

Yes, analog pots of course can be used for some tuning, but for expensive board (400$ is not too cheap) it seems not serious, imho

It looks like crappy 28$ boards from Hobbyking...

As for digital pots, they have less accuracy than analog one's. (more noise).
As for the design I think it looks fairly good, but I will not know for sure until I have tested it over time.
