First off - I fly in Oklahoma where the ground is flat and so I haven't USED verify height. But according to the manual, it doesn't…"

Dumb battery question

I mistakenly ordered a 4S instead of a 3S battery. Given the time it took to come, I am inclined to just keep it.I have a couple of quads that I run on 3S and on which the motors are rated for 3S.…Continue

Hi all,Had to replace an RX, so I picked up the FrSky D8R-XP which supports CPPM. Got it all hooked up and working no problem. I have been reading about issues with this RX's implementation of CPPM…Continue

Scott Berfield replied to Scott Berfield's discussion Altitude as a part of a waypoint"In case I am not being too clear, what I am looking for is either a setting that says "Hit the altitude to consider the waypoint reached" or else separate "AscendTo" and DescendTo" commands. This may exist, but I cannot find…"
Scott Berfield posted a discussionAltitude as a part of a waypoint
I have been poking around, but cannot seem to find the info on this - which means that as soon as I psot this, I will stumble across it --- but...When setting up a multiple waypoint mission, how do I make it so that the altitude of a waypoint must be reached before going to the next waypoint? For instance, if I want to loiter at a waypoint at 5 meters then ascend at the same Lat/Long position to 20 meters, then when I get to 20 meters, fly to the next set of coordinates?WP1: LAt1, Long1,…See More

Thanks"
Scott Berfield replied to Scott Berfield's discussion Power weirdness questi"Figured it out.
I swapped the APM 2 for a 2.5 I have and got exactly the same symptoms - which was doubly weird because even the power connection was different.
I unplugged everything and added things in one at a time.
Turns out…"

Scott Berfield replied to Craig Elder's discussion APM Copter 2.9.1.b has been released"Just flew the newly rebuilt quad that abruptly visited the roof the other day.

Dave Kellum commented on Scott Berfield's blog post Rotorwing using Magnus Effect"The Flettner airplane never flew because it looked to be as heavy as the Eiffel Tower and as aerodynamic. The guy in the YouTube seems to have shed the extra tons of Flettner's design."

Nick Tuttle commented on Scott Berfield's blog post Rotorwing using Magnus Effect"I had a kite once that used this method. A quick googling of "magnus effect" seems to say thit it is primarily a term for rotating solid surfaces? The wikipedia entry mentions Flettner airplanes which also goes on to…"
John Maffetone commented on Scott Berfield's blog post Rotorwing using Magnus Effect"The same principle in baseball gives you a curveball and in golf if you're able to get a back spin on the ball it will magically rise.

I have never seen anything like this, but I want one. Apparently the rotating cylinder creates lift through something called the Magnus Effect.

Continue Checking out my new GoPro - and learning not to accidentally enter Simple Mode
Posted on January 13, 2013 at 7:00pm 8 Comments 0 Likes
We had a dry day today so I thought I would try out the GoPro Hero 2 I got for Christmas. All went well until I accidentally hit the switch for Simple mode without realizing it. Camera mount popped off and was fine, and I lost one prop nut. Could have been lots worse. Let this be a lesson...
H-Quad Ready for Tuning

Got everything hooked up except the sonar and i tlooks like a dry weekend coming so hopefully I can get out and do some tuning and flying. Went with 11x4.7 props since the weight is a little higher than I had planned. May swap the arms for wood if flight times are too short.

Hi Scott - I saw a post from you this past year about your uBlox gps not getting a fix. I'm having the same problem and was wondering how you got it fixed.
Comment by Scott Berfield on September 13, 2012 at 12:23pmJust got one of these and cannot get a lock. the fix light never lights, though the power light does and the Planner software sees it. Not super happy after paying $75.
Thanks!

Turned out it was abad chip/board. I returned it to 3DR for replacement. The new one worked fine.
