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…"

"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…"

"True."

"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."

"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."

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…"

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.

JeffBetts_KK4MTC commented on Alexander LeBrun's blog post ArduPilot Purple + Skywalker X8 + FPV = Summer Loving
"Someone tell me I'm wrong, but there is NOT a particular set of parameters that will work for all X8's. If we were all using the same servos, with same servo throws and arm lengths, and all had the control rods in the same slots in the control arms,…"

JeffBetts_KK4MTC replied to Quentin Mayberry's discussion Tuning a scratch built Quad Copter in ArduCopter User Group
"You may try increasing your Stab P gains, even though it may seem ok otherwise, just before the wobbles appear. That should tighten it up some."

"I agree. I'm flying with 500 watt 780kv 13x6.5 4-cell setup and cruise around 100 watts in low wind."

"I'm just getting started with my build and wonder how y'all have dealt with the ailerons. I'm thinking of cutting them out completely, sheeting on the bottom with 3/32 basswood, installing some Robart hinges instead of taping them.  The foam…"

I just finished building my first tricopter and have been trying everything I can to connect to upload and configure the firmware via Mission Planner 1.1.98. It times out and gives "No Heartbeat Packet Received" error. I'm able to connect to my APM1…
