Clark Hymas commented on Wattas's blog post Getting six fly modes on Futaba T10CAG transmitter
"Is the futaba 8FG similar or is there anyone who has instructions for the 8FG?"

Is the default altitude AGL or ASL (absolute altitude)?  If default altitude = AGL this could explain why I keep gaining altitude while in FBW_B and AUTO.Could someone also give me a description of what Energy/Alt PID adjustment controls or changes…

Clark Hymas replied to Gent Armedo's discussion How do you "nudge" the APM to fly in different flight modes and what is the default failsafe flight mode?
"Information on programming the flight modes can be found here.  As for the failsafe I haven't bothered with it on my radio or APM."

Clark Hymas commented on Andrew Tridgell's blog post The importance of vibration isolation
"Here is what I have done.  Its pretty simple, I am running a four stroke .70 and I'm not having any trouble with gyro drift."

I had everything working and in the tuning phase but something has gone wrong. Even if I put it in STABILIZE while on the ground and move the plane around, roll and pitch are indicated with the attitude indicator but no servos move. I also went into…

Clark Hymas replied to Brian Boyle's discussion PIDs explained?
"I found this that was really helpful on explaining what each one does.  I dont remember if I found it here or somewhere else.

Clark Hymas commented on Krzysztof Bosak's blog post IR DSM from Pteryx UAV - but what for?
"Precision agriculture - excuse me for going a little off topic but this all ties in with the IR and what it us used for in our farming opperation.
Some of the things we are doing with GPS:  at this time we are planting with 5 tractors/planters in…"

Clark Hymas commented on Krzysztof Bosak's blog post IR DSM from Pteryx UAV - but what for?
"To be honest with you - not exactly sure on the camera side of things.  I'm into RC, have been for years, I was asked about the possabilities of setting up a UAV project that could carry the cameras and fly the course.  The farm that I work for put…"

Clark Hymas commented on Krzysztof Bosak's blog post IR DSM from Pteryx UAV - but what for?
"The project that I am working on is to eventually take IR photos of our crops where I work. You have to take 1 digital photo and 1 IR photo at the same time. You then overlay one with the other and then you are able to determine plant health and…"

I am interested in the basics of what each of the 12 PID paramaters actualy controls and the relation of one to another.....I have read and really have a pretty good grip on PID's, the adjustments and gain factors. Servo - roll, pitch, yaw.  …

The title says it all, most interested in fixed wing myself but thought the rotor wing / copter guys might like one too.

Clark Hymas replied to Clark Hymas's discussion APM 2.1.2 fresh download has issues
"listed under                  parameters.h
 'AP_Int16' does not name a type
 
I believe this is what starts the string of many errors"

Downloaded APM 2.1.2 unzipped, opened with Arduino 0022, clicked on verify - I haven't made any changes yet - all kinds of errors.

I flew 4 missions today 1 I would consider somewhat successfull.  I have tried using both APMPlanner and HK GCS.I planned and loaded the missions verifying altitudes of waypoints and altitude of my home possition everything looks good.  I write them…

Clark Hymas commented on Paul Mather's blog post 6 position mode switch for APM - Around $16 total
"Thanks Happy
I saw the first post that was similar to this, ordered the parts, and then the details from the posts were deleted and a link added to ebay.
Planning on removing a 3 pos switch in my Futaba 7ch guessing it will be similar, ordered a…"
