I just noticed this at the Chinese on-line retailer, ThanksBuyer.com
They are pricing the bundled versions attractively. Obviously made to compete against the APM micro 3.1
If anyone makes the leap, perhaps you could keep us informed on your experiences.
Happy flying all!!
Well, I'll be,.. It works.. Turns out it doesn't like the RDF900 modem.. The modem is good, if I unplug the receiver it works, they just won't work together.. that is very odd.. I'm able to connect to the RDF900 from mission planner with another plugged into my PC.. but the dragonlink receiver won't work.. if I unplug the modem, the draginlink works..
the shape of the fc its like the pixhawk !
Hello Michael, thanks for the reply.
I've written a lot here somewhat because you've been nice enough to ask but also it helps me chart my next steps. Feel free to help where you're not exhausted from reading.
I have the Diatone FPV250 with 2206s from Hobby King (Baby Beasts I think they're called) and I have a Diatone Silver #17 which is a racing quad with Emax 1806s. The former is overpowered I believe and the latter might be a bit less overpowered.
I tried the mid throttle position thing last night but my flight log download wasn't successful (first time doing that. I think I was gettng real time data, not in flight data). As I've never analyzed logs before I suspect I'm doing it all wrong. What I was seeing appear on the screen was some intelligible text and the rest gibberish. End result, I haven't identified what my mid throttle position setting should be in order to set it in APM software.
When I attempted alt hold in my basement with the FPV250 I paid careful attention to the quad's actions. I'm now suspecting that the mid throttle thing might be a big contributor. On two or three trials the quad, when alt hold was switched on, simply descended, jumping a bit on way down, to rest on the floor. This was from roughly 5 feet. My hover throttle position was in the neighborhood of 40% throw which makes me suspect I'm overpowered. The overpower thing I think I understand is what throws off the mid throttle "expectation" of the controller.
I'll have to devote a little more time to understandind exactly the data gathering process in order to understand what my mid throttle setting should be. Once I get that potential issue addressed, I'll do as you suggest and start working the PIDs.
Which is another learning curve for me. My PID setting has been all trial and error and I stop when my copters fly reasonably well. I'll have to devote more time to understanding there as well.
All this to say that I'm hopeful/suspecting that it is a setup issue, not a hardware issue. The bummer is that some of these controllers just work and others just don't. Given the home grown nature of all this I'm never quite sure if its me, the (usually knockoff) hardware, or a combination of the two.
Any help you can offer I"m eager to hear.
I'm focussing on eliminating some concerns:
1. mid throttle setting.
2. vibrations (which I've somewhat addressed but have not concentrated on as my other copters don't have that problem and I've not taken taken extraordinary measures other than trying to balance props).
3. dynamic airflow impacting the barometer (the props are by definition near the FC but I do have the foam installed...hopefully that's enough)
4. PID tuning.
Thanks for your help.
I purchased one of the APM Mini pro's. I am trying to connect the osd and sik radio to it but based on the images I've seen, it seems there is a discrepancy about where you connect the OSD, I've seen it being shown connected to the UART0 port and one showing it connected to the Telemetry port. Can someone confirm where to connect these two items. thanks
