Transmitter Trouble

Hi Guys,
I am slowly learning about Multiwii and what not but when I mess with the throttle and other sticks on my transmitter in the config program I am only seeing ranges from 1071-1977 (similar on all sticks).
I've read about modifying values but I can't find anywhere in the code that deals with this sort of thing.
I can't seem to arm my quad because of this.
I'm using a basic 4 channel Tactic TTX404 transmitter/receiver combo.
Any ideas?
Thanks,
Alex

Look in the MultiWii Tab.
Code: Select all
// ******************
// rc functions
// ******************
#define MINCHECK 1100
#define MAXCHECK 1900
Adjust the values to match your radio.

So change it to:
MINCHECK 1071
MAXCHECK 1977
Is this correct?

Should I use my absolute max/min values for all 4 channels (throttle, pitch, roll, yaw) or just the minimum from the throttle channel?

I'm not sure what your asking, but i set min and max on mine to match the gui readings of my TX min/max. i was unable to set trim before i did that.

If possible setup your radio to reach 1000 - 2000 µs on all cannels.
Then all functions and stickCombinations for Trimming the model will work.

Well, I'm really new to the whole RC scene so I'm not sure how to setup the radio, or even if I CAN...its a pretty inexpensive Tactic TTX404 4-Channel transmitter. How would I go about adjusting the range? I can adjust the trim for the channel but that only moves the midpoint, giving me a lower low end, but also a lower high end...not increasing the overall range.
I set the MINCHECK and MAXCHECK to match the values on the GUI but it didn't help at all...motors are still not arming...

Well I figured it out, in the GUI the three little boxes next to "ARM" were turned on, I turned them off and it worked. I also put MINCHECK = 1300 and MAXCHECK=1700 but I'm not sure if that helped or not.

Yes it helps. You need a value under MINCHECK to arm your quad, but be careful if you have min value=1071 on your tx Yaw or Roll channels and you put MINCHECK=1300, there are 1300-1071=229 difference. You will turn off the motors easily during the flight.
