"After loading 2.5.5 and cellar take off I had a nice flip. I took the quad in my hand and thottled up to find out what's wrong. After 20sec it would have flipped again. Reboot, same procedure. Would have flipped after 20sec.

I smell a bad burned…"

"Very nice. Congrats.

I'am still struggling with mine. Some unexpected problems."

"Congratulations Jordi."

"It's already there on the frontside of upper deck, it's just a bit small in this release. "

"Hi Alan

Its simple. 1.x means all software builds below 2.0 for Qudrocopters. I am not exacly sure with what SW release Jason implemented multirotors other than quads.

2.x means SW builds revision 2.0 and up for multirotors.

"Thanks for the flowers. The carbon parts are CNC cut and "homemade". The clamps have been on a water jet cutter from 6mm alloy sheet.

After beta testing in early 2011 I had some bad crashes and my concept of precise machined and glued carbon did not pay off. It was almost impossible to replace broken parts. This made me think of a different concept.Few parts that can be used all…

"Hi Bill

This project is amazing. I would be in if you think about selling your boards.

Keep us up to date.

Jason, thanks for your endless and persistent work. I flew my custom quadro today and tested Stabilize and AltHold.Stabilize worked very good for me.AltHold seemd to be fine when I switched to AltHold at maybe 2m above ground. After a few secs the…

"Hi Doug

I made the logging work with CLI -> disable cur, enable cur. Last time I used disable all and then enabled log by log.

As soon as I have a log, I will let you know. But the next days are not very promissing. Too much rain.

I was flying today and the code is awsome. The last flight was the "best" regarding orientation of the plane. Unfortunately there where no logs recorded although they where enabled.

I think we can close this now.

"Hi Doug

I was looking at the sin() & cos() as well but I does not seem to solve the problem. We have good corrections this way at east orientation only. If you find a solution without trigo functions - good. I stop then refreshing my geometry skills…"

I was flying the SQRT corrected compass today. The syptoms persist. Whenever nav_roll turns negative, compass has an upper and a lower cap.

Ah, when we power two negative values we get a positive value. But for one side correction we need…"

"Doug

a simple question

Trigo definition: sin2 A + cos2 A = 1

in Compass.pde Line 78

sin_roll = 1 - (cos_roll * cos_roll);

in MHO it should read sin_roll = SQRT( 1 - cos_roll2) according to the trigo rules.

same for sin_pitch.

I did not calculate it…"
