I have a Futaba T7CAP transmitter w/ a 72Mhz PPM receiver. Calibrating the transmitter via the configurator never succeeds. Here is what I have tried:

1) Verified the receiver works by directly plugging in an esc to the receiver.

2) Verified the receiv

How to correclty test ArduIMU v2 Flat with Ardupilot?

Hi all,

I'm using the configuration shown in this setup: IMG_4778.jpg

I've uploaded the firmware 1.8.2 to the ArduIMU v2 and I have configured the ArduIMU according to the manual (http://code.google.com/p/ardupilot/wiki/ArduIMU). When I connect the F

Hello All,

I've searched around, and found a lot of discussions on the MTEK GPS and APM.

I've tried everything I know to try, and am at a dead end.

I have the MTEK with NO BATTERY.  I successfully reflashed the unit by soldering pins onto it, and hoo

Arducopter programming: how to change PIDs?

Currently I am doing on the arducopter and I have encountered some problems about the programming part.

Firstly, how do I vary the PID values for my quadrotor?

I have found certain lines in the programming, is it changing this to do? (I am using stabl

Battery charging question.

Is it bad to charge batteries in the cold? I mean something like outside where it's like mid 30's. Or what is considered too low for charging temperature wise?

Conflicting radio frequencies

If I use xbee telemetry at 900 Mhz.
Can I, or is it possible to use a multi channel 900Mhz Video Tx/Rx system along side it without conflict?

As the video has numerous channels I should be able to find one that doesn't interfere with the telemetry, sh
