About Me:

I tinker with all things.

Please tell us a bit about your UAV interest

Primarily interested in flight control and telemetry systems.

Dan Banks commented on CSG's blog post 433MHz Super Long Distance FHSS LoRa Wireless data modem with USB UART 5+ km range
"There is a narrow ISM band in zone 1 around 433/434 MHz (and a few others that Gregory didn't list above), but there is certainly NOT a global ISM band spanning 414-454 MHz, or even any global ISM band in any part of that range.  This device is…"

"I don't think the FAA has any jurisdiction in Canada :)"

Dan Banks commented on Robert Gubala's blog post LiPo disaster
"Robert, you mentioned you were monitoring cell voltage on a computer.  Do you have any logs that you could share?"

Dan Banks replied to turdsurfer's discussion Dear future, pls bring me Mavlink telemetry over analog audio for FPV antenna tracking
"I did something like this many years ago, although my approach was somewhat crude.
My A/V transmitter was in the 2.4GHz band and included stereo audio.  Over one of those audio channels, I sent telemetry data at 38.4kbps.  Over the other channel, I…"

Dan Banks replied to Sari Mira's discussion Do the ESC's have to be the same kind?
"Different ESCs running different firmware can have different response characteristics to changes in throttle.  Whether these would be potentially significant enough for you to notice, I can't say.
I would expect that the flight controller may be…"

Dan Banks commented on Andreas's blog post Deadly RC Helicopter Accident in Switzerland
Cutting power would only be useful for preventing additional damage after an initial collision.  The real damage comes from the energy stored in the spinning rotor, and there is very little we can do about that when an obstruction suddenly…"

Dan Banks replied to Misha Sweeney's discussion Whole Slew of Newbie Questions
"First, I have to agree with Doug's sentiment that you should visit a local RC club.  Years ago, that was exactly my first step.  The hobby is cheaper and easier to get into now, and information is much more freely available courtesy of the…"

Dan Banks replied to Brian Chawner's discussion Lipo battery flight time estimate help needed :(
"How much will your quad weigh when it's complete, and where did you come up with 12A per motor?"

Dan Banks replied to Leonard Palumbo's discussion Quadcopter Unstable With 15” Propellers
"I believe the suggestion above to reduce your PID gains is good advice.  Larger props produce more thrust at a given RPM, so using larger props is somewhat analogous to increasing your control gains.
Also, your change in motors made the problem…"

Dan Banks replied to keeyen pang's discussion Power module voltage fluctuation
"Some information I posted here: http://www.diydrones.com/forum/topics/apm-2-5-and-3dr-power-module-... may specifically be helpful to you."

Dan Banks replied to peter christian's discussion 10000mah Battery capacity - seriously?
"The weight on the first one seems rather low compared to the batteries I'm familiar with.  I would not believe the stated capacity unless I measured it myself.  The two 3S batteries seem more plausible in terms of the stated weight and capacity.

Dan Banks commented on Richard Evans's blog post The future of GPS
While I'm not specifically familiar with who may have held licenses to that spectrum previously, the issue here is space-based vs. terrestrial use.  The spectrum was licensed for space-based transmissions which (by their nature) do not…"

Dan Banks commented on Richard Evans's blog post The future of GPS
The filtering requirements on GPS receivers were based not on "assumptions" about the adjacent frequency bands, but the fact that these frequencies were reserved for satellite-based transmissions.  More selective filtering does require…"

Dan Banks replied to Jason's discussion glue on props
"I know this is a little bit of a necro, but I wanted to post a follow-up, and I've seen a handful of posts on the topic in other threads as well.
I ended up going with the E-flite adapters ordered through my local hobby store as planned, and I've…"

Dan Banks replied to Nicholas Ee's discussion Need help for approx 35lbs AUW Octocopter X8 props and motors!
"I think that what you're asking for is unrealistic.  I did poke around at http://www.ecalc.ch/xcoptercalc.htm a bit, but I think these conditions would be out of the range of what can be reliably predicted on that site.
Your first problem is props. …"

Dan Banks replied to Oliver Volkmann's discussion Rate of Climb/Descent vs. Throttle
"I haven't been a member here long enough to know if others have tried this, but here are my thoughts on what you would want to do:
First, reduce the size deadzone on the throttle stick significantly.  If spring centered, you don't need much of…"
