bi-copter v2.0

[LuisFCorreia]

Hi guys,

one year later, I return to my bicopter build.

Here's a video of it's current build, where I'm just assessing if the remote sticks match the expected servo movements.

Multiwii is running from SVN trunk as in last weekend, and the PID settings were zeroed.
No gyro/accel is mounted, so technically, multiwii is doing nothing much then muxing the data from the receiver into the servos.

the right servo is acting up a little and the left one has a mechanical mount error, that I will fix soon.

Please let me know if so far things are looking good from the assembly prespective.

Thanks!

The servo movement appears to be correct. There is going to be a small about of servo jitter regardless, this I would consider normal especially for analog servos.

I am not sure if you are already doing so but you may want to power your servos separately from the FC. Example, use a UBEC for the FC and ESC for the servos.

Hi guys,

one year later, I return to my bicopter build...

Wow! really well done. Best bicopter implementation so far!! keep up the good work.

The other bicopters I've seen aren't really that good at all.

Having fun again? Talk about Bipolar! Ha

As for power, I'm using a 7805 1A regulator for servos and arduino.
The ESC +5V output is not being used.

Yesterday I found out that strangely, my remote has two different values on the sticks.
Yaw, Pitch and Roll provide 1020-1960, with center being 1500.
Throttle only goes from 1120 to 1860.

I guess adjusting MINCHECK and MAXCHECK will be necessary.
However, I do not know which values to use and am currently open to all kinds of suggestions.

The end result is to use my own Android app to control the copter.
At this time, I'm still assessing all the mechanical factors involved, before delving into software.

Hi again,

here's a new video showing off the new propellers I got.

Please note, it DOES NOT have a gyro installed yet! That is the reason I'm holding it.
