Hmm - OK. It looks from the ProgressiveRC photos as if PRC6 (as opposed to EC5) are both round. I will probably try them anyway, thanks.

But I'm saying even for the two-blade, are you using the KDE 18.5" blades or some other 18"? Maybe I'm getting too picky worrying about the extra half an inch, but the T-motor specs top out at 18" so I want to be sure. Thanks again. (I see your followup now, OK.)

thanks. Would you feel OK running the extra half inch on the 18.5", or is that in fact what you are using now?

@Giovanni59 wow! That is a bummer; I know how it feels. BTW how do you like the PRC connectors? The only concern I would have in passing those onto a user in the field is no polarity distinction. Many of us have learned to respect these big rigs but folks looking to survey a field or something...

Hi guys, (only really interested in objective findings here, but I know these things get contentious sometimes...) I've seen a lot of chatter on other forums about various compatibility issues with U7 and I know the T80a is the recommended ESC. How do you guys feel about this setup vs. an...

Good to know, thanks. I have been wondering about this and a thread suggests (but never resolves) an issue, but that is only 1 data point. What motors are you running with them?

going to be modifying this with rcexplorer 10mm square cf arms (325mm/12.8"), and QuadFrame motor mounts. The 10" wood arms are too short to keep it stable with proportionally significant inertia front and back. Also will give more flexibility shifting weight to balance cg without getting too...

yeah. Calling it Pixhawk 2 was silly to begin with, though, as it's no more unique from Pixhawk than some of the mildly altered designs such as Pixhack. It's essentially the same. The improvements are things like "boat mode" (launch from a moving platform) and that sort of thing.

The Solo fork is not being merged until 3.4. He's not running 3.3. I think he just needs to learn about how the alt hold controller works vs. linear throttle in Stabilize. Right. @Chalagi you also should check the mid throttle setting is correct.

Sorry, I was speaking about both the Pixhawk flight controller firmware and the Taranis and OpenTX. Pixhawk runs the APM firmware (which is currently at 3.2.1, with 3.3 being released shortly). And you're right, OpenTX 2.1.3 is the latest firmware for the Taranis and will work great with...

Even tail heavy if you have a 3d fix it will generally hold a position in Loiter. Give it another try. If you're running APM 3.3 there are beeps to confirm a flight mode change, or likewise a beep to indicate refusal to change if for instance you select Loiter and it doesn't have enough sats...

@Chalagi sorry I just assumed you were using the OpenTX Companion desktop app. I have my Taranis updated to the latest OpenTX as well. The factory Taranis firmware is a bit different. Either way you could open the eepe file in Companion and poke around even if you don't end up using it directly...

@Chalagi at long last here is an example of my OpenTX setup. Remove the .txt, I had to add it in order for the attachment to be allowed. This is inspired from a diydrones thread which also had some good examples. I think I started from Marco Robustini's settings. One change I made is that it...

you probably just hadn't hit the safety button or didn't have the radio on. With 3.3 there are tones to indicate "failed prearm checks" as well. Also since 3.3rc11 (and with what will become the release for 3.3) you will have specific text on Mission Planner indicating the prearm check that is...

right. Exactly the kinds of things I think would be useful to adjust via sliders in flight (including the banking coefficient for Drift). Part of the challenge with APM for beginners is that there is so much you 'could' do, and on the forums there is always someone asking for a new adjustable...

why do you say that? It's pretty much just Loiter without the speed limitation and with yaw/roll combined. Depending on how you fly, it's be no different than flying in PosHold. Do you mean due to the braking effect? If so, PHLD_BRAKE_ANGLE or PHLD_BRAKE_RATE can dial it back. (BTW I am keen to...

hence 'with confidence' :) only once the confidence is there to take off and land should one rely on the more automated modes. Trust me I know as well!! Nice scar on my hand to prove it in fact... Some advocate for using motor kill switch or the new motor interlock switch as a manual override...

Are you sure? The mode referred to as "Stabilize" is essentially identical to "Altitude Hold", except alt hold uses the altimeter (barometer) to try to maintain altitude. There is no reason you should be able to arm in one but not the other. When connected to Mission Planner, it will tell you...

Cool I'm out and about but will do it later on or tomorrow. Sent from my iPhone using Tapatalk

What radio? I can share my OpenTX settings if it would be helpful. You can use ch8 for RTL if you wish. Personally I like it tied to a dual switch flight mode mix where one switch down overrides the other so it works no matter the other switch position. Then you have 7 and 8 for autotune, save...
