"Hi Bill. Thank you!
I don't have hard numbers for you at the moment. Props are 13x8 MA 3-bl, and we're planning on a flying weight of < 5 lb
With the prototype I'm getting about 8-10 min. But it weighs almost 7 lb. I'd have to confirm this…"

"Hi everyone, I'm the designer and builder of the eVader aircraft in the photograph. Dan wasn't far off about using cut-off sand pails for the ducts. I used some garden planters from Home Depot.
The basic APM code for the eVader is the same as for…"

Hi all,My new bicopter prototype - the Nymbus 650 - uses a mod of the original APM airplane code and two fixed-pitch airplane props. Hoping to have your feedback. Here are some clips, some alongside a T-Rex heli, and some partially from the on-board…
"Thanks Dave. Please keep me posted on your progress.
I went to the Bramalea flying club outside Toronto this past weekend and had the opportunity to fly alongside a heli. Lots of fun!

"Hi Bill,
You had said that it was possible to get the raw gyro drift down to 0.18 deg/min. I'm wondering if - since the the earth rotates at ((360/24)/60) 0.25 deg/min - this is in fact a measurement of the earth's rotation (average of the pitch…"

"Hi Bill,
Thank you for allowing me to post your reply at RC Groups, which I've done. I think ideally, rather than just reduce the horizontal drift that they cause, the accelerometers would be actively used to prevent drift. That may be a tall…"

"Hi Bill,
Thank you very much for your thorough reply concerning copter horizontal drift. Would you mind if I posted it at the RC Groups ArduPirate's thread? I will try the modifications you suggested, and look forward to hearing of your…"

"Hello Bill,
I've noticed what I think is a potential problem when using your DCM algorithm in multicopters instead of airplanes. The code appears to accentuate vehicle horizontal drift. I've described the issue in detail at the ArduPirates build…"

Hi, Somone graciously loaned me his ArduPilot Mega to try out on my bicopters, and I've managed to modify the APM 1.02 (airplane) code so that the board emmulates my gyro/mixer module. I haven't flown with it yet, but I imagine that - with the…
"Thank you Jean-Loius. There's certainly a lot to learn.

"Hi Jean-Louis,
Someone very generously donated their new AP Mega for me to try out.
