Freaky Phase angle on 450

Started this discussion. Last reply by Joly May 7, 2013. 17 Replies

My 450 has a wobble on the pitch axis, unless 42 degrees of H_PHANG is added. It appears as a rapid clockwise toiletbowl effect, which subsides as H_PHANG approaches 42 degrees. If H_PHANG exceeds 42…Continue

Fixing the gap with the APM 2.5+ side entry case

Started this discussion. Last reply by Eric S. Jul 12, 2013. 1 Reply

I got my APM last night, and I'm very impressed with this hardware as a whole. I did notice that there was a problem with the way the case looked. The case came cracked and the gap around the side of…Continue

Joly commented on PX4's blog post PX4 and 3D Robotics present Pixhawk: An Advanced, User-Friendly Autopilot
"+1 for a small version I'd buy one that wasn't designed for all-out mega-size copters. Something called "Pixhawk ultra-lite" with only 4-6 PWM outputs, PPM-only input and ultra-small footprint? Either that or someone suggest an…"

"Hey Rob, I posted this here because its not really a dev issue. My COLYAW is linear --- not V-shaped like it should be, always has been. Except for about 2 flights. I think its a bug with the code, but might be a setup issue. Remember ages ago…"

"Leonard you were right, switching back to acro from stab doesn't revert to last attitude. All good :) I love flying with this mode!! Seriously well done team :)"

"Hey leonard, nice work on the acro code, I'm loving it :) I've observed something while bench testing, not sure if this has been covered. When changing from Acro to Stab while flying at a given attitude, that angle is the target while…"

"Just got my case (but I have the rctimer board).  Mine fits even worse but maybe it's rctimer's fault.  My side pins do not extend anywhere nearly to the side hole in the case and I guess I need to trim the pins after soldering…"

"Rob, I think the "feel" is more of a rate controller issue -- if we get the acro mode correct that is. What I mean is, if we get the geometry of EF to BF translation right, then the feel only comes down to how the rate controller behaves."

"Regarding stabilize at min throttle, wouldn't it be better to have a standardized acro mode as default, then have optional extras that the user can select? Otherwise it will be impossible to satisfy everybody. Multiwii has a matrix-style of…"

Joly replied to Bob Doiron's discussion Flipping Arducopter
"Hey Bob nice work! I'd like to show my support for an improved BF acro mode like this. Moreover, an acro mode that has the possibility to run in pure rate mode (aka no levelling), similar to the one R_Lefebvre wrote, would be…"

Joly replied to Josh Potter's discussion 500 heli on APM 3.0.0 code flying great!
"Firstly, you've got balls being the first to try 3.0.0 on a heli :) Nice work The tuning params will be different from a quad, especially rate, accel, and throttle gains. In acro and stab, it should fly the same as 2.9.1 since that part of the…"

Joly replied to Rob_Lefebvre's discussion Arducopter 2.9 for TradHeli Discussion
"Not sure if it matters or not, or whether you are aware of this already, but I noticed that in 2.9.1b the extrenal gyro gain is impossible to get realistic PWM output when using ch6 tuning. The max I could get was 32 PWM. I changed the…"

Joly replied to Rob_Lefebvre's discussion Arducopter 2.9 for TradHeli Discussion
"You are right, my gains are higher than before. I did notice the servos would "stick" to max cyclic for a couple of seconds after holding max roll or pitch, as though the i-term was saturating the output, hence me changing IMAX to 2500.…"

Joly replied to Rob_Lefebvre's discussion Arducopter 2.9 for TradHeli Discussion
"For info, the params Randy recommended are in fact the correct ones. I've set the main rotor up as follows:  +/-10 degrees of collective pitch +/- 9 degrees of cyclic pitch (H_PIT_MAX and H_ROL_MAX to 2500) Set RATE_ROLL_IMAX and…"

Joly replied to Dave Smith's discussion N00B Questions
"The board MUST be mounted flat in relation to the main rotor and with the arrow pointing forward. Other than that, as long as it is isolated from vibration it doesnt really matter where you mount it. If you are going to transfer your setup from one…"
