Long ago in a galaxy far far away I built an RC solar plane.

I have a lot of switching power electronics on this plane and it was before 2.4Ghz radios were common. The power electronics caused interphereence

Its been a few months since I plyed with it and I was getting back to it today.
I've got (but its not soldered up or installed) a Ardupilot board with the mega 2560.
Do I need the

I use it to practice my orientation skills without bending real hardware.
Whne I ordered my ArduCopter from Jdrones I started looking for a simulator that had a quad.
The visual presentation of a Quad is very dif

I think this is probably too much weight for a stock arducopter (mine is a jdrones kit)
Jdrones offers upgraded motors and esc's (I have 4 of the 30A esc's) but is out of stock on th

Until last month I'd failed.
I'd heard good things about the http://www.pixelqi.com/ screens.

I built a Jdrones Quadcopter kit.
I've done all the setup and it has some strange behavior.
When I apply throttle to take off it tilts to the back and to the left.
Will almost full forward and full right stick commands it will almost hold level.

1)The default baud rate of 57600 has a large error on an 8Mhz AVR.

I've been following the IMU discussions with much interest.
The DCM imu work is very interesting, but it is fairly specific

I purchased two ifrontech 5.8Ghz transmitters and and two receivers.Nicely packaged clean looking equipment, but I've been really disappointed in the performance, one RX is DOA and the other RX does not work nearly as well l as some other cheap 5.8gh
