Dumb battery question
Started this discussion. Last reply by Neill McOran-Campbell Apr 29. 4 Replies 0 Likes
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

I wonder how long DJI is going to continue with the silly pricing scheme on their helicopter systems?"

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
Posted on January 11, 2013 at 12:25am 1 Comment 0 Likes
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.

H-Quad Part 2
Posted on January 6, 2013 at 9:30pm 2 Comments 5 Likes
Here's where I am so far on the H I started before the holidays. Ended up trimming the arms and drilling out some of the plates to lessen the weight. Will likely add some CF rods as prop protection during the tuning process.
Using 10x4.7 props for now, though the motors could handle larger. Testing has it hover at just under 50% throttle, so I think I am in a good place. Not tuned yet - that's next when the rain lets up.
The APM is enclosed…

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!
