JeffBetts_KK4MTC commented on Alexander LeBrun's blog post ArduPilot Purple + Skywalker X8 + FPV = Summer Loving
"Start with the defaults, or if you want to be extra safe, drop the default P values by 25% and expect it to be a bit sluggish in self-leveling. If it's too high you'll notice diminishing over-corrections which will be noticeable as it will want to…"

JeffBetts_KK4MTC commented on Alexander LeBrun's blog post ArduPilot Purple + Skywalker X8 + FPV = Summer Loving
"You can't copy the PIDs from one airframe to the next and expect decent results. Especially on this airframe since the servo arms are various lengths (depending on which servos you choose to install), and connection points aren't consistent from…"

"I fly 4S 6600mah (2x3300) and with 12x10 prop pull around 45amp at WOT. Plenty of power, but won't climb vertical, which is ok with me."

JeffBetts_KK4MTC replied to opiq's discussion X8 Carbon with total weight 4kg in X8
"I don't think power is the problem, but you could do some damage to your motor with that large of a prop and 6S. I use a surgical tubing and paracord 'hi-start' launch to help get mine up to speed and up to 10-12 meters in altitude before starting…"

"How did you attempt to launch it? Bungee hi-start or hand toss? Where was your CG? What happened when it was released? Nose dive, roll, etc."

JeffBetts_KK4MTC replied to Josh Gluck's discussion trouble with pitch: dji f330 w apm2 and ac3.01 in ArduCopter User Group
"I think you may be adjusting the wrong parameters. 4.5 seems too high for pitch/roll stab P values. I think you are adjusting the 'stick response' values, which I always leave at 4.5, or 45deg. My stab values are in 0.015 to 0.15 depending on…"

"Arrato, The defaults worked in stabilize, but I found they needed to be turned down a bit to keep it smooth, but beware of using others PID settings. Chances are your servos, servo arms or control surface brackets are mounted in different locations…"

JeffBetts_KK4MTC replied to Edgar Scott's discussion Getting latest update for my AMP 2.5 from mission planner gives error in ArduCopter User Group
"I started getting the same error when trying to update my Hex about 10 days ago. I shelved it in hopes that the problem would be discovered, as it seems to have.
I have updater.exe in MP root directory, dated May 25, 2013."

JeffBetts_KK4MTC commented on Tommy Larsen's blog post Skywalker X8 hand injury
"I had a very similar result ONCE. Now I use a shortened version of my high-start bungee to get it airborn, then kick in the motor once the launch link/ring has dropped. It was a 13.6x5 that got me three times. Never again."

"Awesome. I'll be glad to help beta test it. I have multicopters and fixed-wings flying with APMs."

JeffBetts_KK4MTC replied to Brady D's discussion Connection Error in APM Mission Planner with wireless telem
"I'm having this same problem. I'm using MP 1.2.34 and ArduCopter 2.9.1 for Tricopter. I had been able to use my 915mhz 3DR radios until I powered up and a friend connected to my tri when trying to connect to his quad, since we were both running…"

JeffBetts_KK4MTC replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released
"Just when you think you have it figured out, gravity wins. I've been flying tricopters APM2 since 2.5 and have had tremendous success. I couldn't wait to install 2.9 and take advantage of the new features. I added some 1/4" foam rubber below the…"

JeffBetts_KK4MTC replied to Stan's discussion Lawmate 1000mw tx with DX8 - can this work ? in ArduCopter User Group
"I believe you need to use a different frequency for video tx/rx and rc controls. Even though the DX8 is FHSS, I've read to always use a different freq for each signal transmitted, and separate the antennae as much as possible to get best…"

How difficult would it be to record GPS coordinates as you flew and then use those breadcrumbs to retrace the way back home when RTL mode is selected or as failsafe on signal loss? instead of jumping to altitude and then making a direct path home.
