Robert B Von Haden commented on Phillip Kocmoud's blog post Caution with the FAA UAS Registration Site
"It looks like the registration site is being taken down in the evenings for maintenance.  They do not even know how to properly write their notification, saying "tonight" rather than giving an actual date.

Robert B Von Haden replied to Yochai 360Video's discussion HexaCopter Can't lift Itself
"Your blades and battery may be undersized for the KV of the motor.
That motor can go to a 6s battery and drive blades around 17-18 inches.
You might try larger blades first."

Robert B Von Haden replied to Kris's discussion Sunnyskys
"The Kv ratings are basically how fast the motor spins relative to the voltage applied.  Google "multirotor motor kv" and you should get some good hits explaining the concept.
Generally higher Kv are used with smaller blades and lower Kv are used wit…"

"I have a few multi-copters running with Sunny Sky motors and they work great.  Got some from www.buddyrc.com and others from www.simplecopter.com.  Hardy little workers.
I have a v-tail quad running X2212-13 KV980 II SunnySky motors which has been c…"

Robert B Von Haden replied to Robert B Von Haden's discussion LidarLite on Pixhawk setting zero range
"So this is where it is a little tricky.  I use both the APM Planner 2 and the old Mission Planner for configuration.  I started with APM Planner 2, which has the configuration setup for the Lidar Lite, and then after configuring some of the newer fe…"

I have the LidarLite on my quad with a Pixhawk controller running software version 3.2 and I see the ranging values in the setup screen.  When the quad is sitting on the ground on the landing gear, the LidarLite is about 50cm above the ground.  Does…

Robert B Von Haden replied to J M's discussion Cry for help to successful Pixhawkers: Esc calibration works but cannot get motors to spin after
"Ok.  Sounds like you are following the instructions, but something must still be off.

I too use a Spektrum DX8 transmitter with the AR8000 receiver.  One thing that tripped me up when I was setting up my unit was the servo settings because the up/d…"

Robert B Von Haden replied to J M's discussion Cry for help to successful Pixhawkers: Esc calibration works but cannot get motors to spin after
"Sorry to hear you are having issues.

The issue may not be motor calibration.  Have you followed the instructions on the pre-arm page http://copter.ardupilot.com/wiki/prearm_safety_check/ and Arming page http://copter.ardupilot.com/wiki/arming_the_m…"

Robert B Von Haden replied to David Antwis's discussion Pixhawk With V-Tail Quadcopter???
"Hi, Dave,
I have a Pixhawk but it is on a Hex (6 rotor), not my Quad V-Tail.  I meant by my comment that the V-Tail I have is very sporty, not to say that Pixhawk supports the V-Tail configuration yet.
The dimensions may be found on the 3DR store ht…"

Robert B Von Haden replied to Steven Hickerson's discussion Newbie questions for someone that wants to experiment with drones
"Hi, Steven,
You are asking all the right questions.  The area of multicopters is still in its infancy but even so there is a huge amount of variety in feature, form, and functionality out there.
There are a lot of cool frames available, some with mo…"

Robert B Von Haden replied to David Antwis's discussion Pixhawk With V-Tail Quadcopter???
"I cannot speak to this specific Lynxmotion V-Tail design, but I have a SimpleCopter V-Tail which I really like.  It is running a KK2 board and it is a very sporty flying vehicle. I am learning how to do flips with it which is great fun. The KK2 is j…"

Robert B Von Haden replied to Bryan Anderson's discussion First Time Builder
"My actual experience with these boards is just with the APM (multiple successful flights), the KK2 board (very fun acrobatics), and the Pixhawk (setup and ground testing - no actual flights yet).
There are other controllers out there to which I cann…"

Robert B Von Haden replied to Bob Loesch's discussion Pixhawk cabling questions - Newbee
"At least when I received my Pixhawk, power module, 3DR radio, and GPS module they each came with the appropriate cables for connecting to either a Pixhawk or an APM, and all the 6-6 cables were fully connected.  The APM uses the 6-5 pin DF13 cable f…"

Robert B Von Haden replied to Bryan Anderson's discussion First Time Builder
"If you want to connect something with different end connectors than what comes with the PX4 cables, all you need to do is cut off the cable end connector and replace the it with one which fits your purpose.  Some sites sell the cables with just the…"

"Hi, Bryan,
You may avail yourself of the pre-configured add-ons like GPS, external compass, power/current sensors, gimbal controls, light controls, telemetry, and FPV OSD.  Or you may build and integrate your own devices because the code which drive…"

Robert B Von Haden replied to Bryan Anderson's discussion First Time Builder
"Hi, Bryan,
I have not really looked into what you would need to write a custom program to control the APM or Pixhawk.  All I know is that the software for both controllers are open source so the code is available for you to look at to figure out how…"
