Craig Fraser commented on Earl's blog post CAUTION ..I REALLY mean it !
"My very first LiPo (ThunderPower=not so cheap) burnt spectacularly on my very first flight with it lol. This was when they were kind of new and the first cars/rooms had just started getting burnt during charging.
Anyway, my excuse is I had…"

"Very nice! Do you live at an airport?"

Craig Fraser commented on Chris Anderson's blog post Flight of a "Cyclocopter"
"Put it upside down, and I bet it could really rip across the water..."

Craig Fraser commented on Bernardo M. A.'s blog post Parachute tests with a multirotor
"^ Somebody, somewhere in this blog (months ago), demonstrated a chute using the "bent springy rod" technique...seemed to work just fine.
Alternatively, the hobby rocketry technique of blowing out a chute from a tube using a small black powder charge…"

Craig Fraser commented on Lorenz Meier's blog post Help Us Improving the Status Feedback of APM and PX4!
"Yeah, that DJI system is about as helpful as nothing (of course it can be learned...). Consider traffic lights. Simple, no misunderstanding (though I admit *some* people don't know what to do when some colors of traffic light are flashing). If it's…"

Craig Fraser commented on Hugues's blog post Even More ! Possibly the cheapest (and quickest) way to dampen a hard landing
"You can also cut off about a 2" length of pool noodle, then half it across the diameter. Fold it around then Ty-rap one of those pieces to the end of the 3DR leg. Some shock absorption, plus a great "bootie" if flying from messy ground, helps…"

Craig Fraser commented on Stephen Carlson's blog post Introducing the "Orange Hawk" Tricopter/Flying-Wing VTOL UAV
"Great work!
I can't help but think this sort of thing (VTOL aircraft) is really what a lot of people want, rather than a pure copter or plane. They just haven't had a lot of (economical) chances to find it out yet though... With some natural lift,…"

Craig Fraser commented on Gary McCray's blog post Vibration Control Wiki Section Started for Better or Worse
"Yes Gary, it has to be addressed formally, sooner or later. I'm sure it's being looked at.
Thing is, it almost certainly can't be something as simple/functional as what I euphemistically called "grommets" above. Due to the APM's low mass, though one…"

Craig Fraser commented on Gary McCray's blog post Vibration Control Wiki Section Started for Better or Worse
"I won't be satisfied until there are some kind of "grommets" that can be screwed down. A totally repeatable method/process that also anchors the APM, IOW something that 3DR could include in a kit and say "use these" and pretty much no other…"

Craig Fraser commented on Stefan Gofferje's blog post Easy to use FrSky-library for Arduino
"Agree about the FrSky telemetry interfering with GPS, it certainly does here. A little space helps adequately, wrapping the case in copper foil helps some too. I don't know how to disable it...the documentation I have is extremely unreliable,…"

Craig Fraser commented on Xerravon's blog post Easy LED Sonar Heater
"Here's what we commonly use in "hobby astronomy" (as an alternative): 330 ohm 1/2W resistors. The last bag of 100 I got at digi-key was ~$3. This is for 12V/3s use only, adjust resistor value for other voltages. Parallel as many resistors as you…"

Craig Fraser commented on Gary McCray's blog post Vibration Control Wiki Section Started for Better or Worse
"I think some people (not here) are trying to directly translate their vibration experience with helicopters to multicopters, and thus the proliferation of "that doesn't work" comments in some places. Those with more experience, or those who played…"

Craig Fraser commented on Gary McCray's blog post Vibration Control Wiki Section Started for Better or Worse
"Thanks guys. I am still experimenting, I still gotta try those E-A-R things on the APM board itself too. Though I much prefer the idea of screws/standoffs/grommets etc. so everything is tied down if possible (my preference != good necessarily).
And…"

"^ Do you deal with them through work? [That's another fabulous source I no longer have access to, unless they've changed their "Canada policy" re individuals.] Of course somebody in the U.S. could provide them to the various 3DR distributors etc.…"

Craig Fraser commented on Stefan78's blog post Alternative 3DRobotics Hexa Frame (based on 1,5 x Quad-C)
"It was just a thought, not exactly what I had in mind (was thinking lighter and rectangular), but was all I had saved that was large enough, low profile, and opaque. Some people like to show all their guts, and some like to hide them (I'm more in…"
