Hi there, tried to "autotune" PIDs on my Pixhawk which is configured to drive a V-Tail Quad. The V-tail Quad flies quite ok already but sometimes it behaves a bit unstable/nervous in the air - that…Continue
"I do not want to sound disrespectful but I wonder if there is indeed a working prototype that can fly? All pictures I see on the website are just mediocre renderings and the only video on the site showing the real thing does not show it in action.…"
"Short update: The co-processor was indeed the problem. When flashing new firmware both the main-processor and the co-processor get updated. Somehow the updated for the co-processor failed resulting in a broken RC-input. Flashed the co-processor…"
"I have once more contacted 3DR support and told them, that obiously there is a problem/incompatibility 3DR knows of but does not want to admit. Otherwise the 3DR support engineer would not have been able to tell me spot on the last version of…"
"fred... obviously only specific board revisions are affected. Most Pixhawks work fine with the latest software unless you have bad luck and have one of those intermediate board revisions (2.3, 2.4, 2.4.3, 2.4.5... don't know for sure yet which…"
we've recently had the same problem like the thread opener. After the update to arducopter 3.2.1 there was nomore PPM-input signal visible in Mission Planner. We've contacted 3DR support and asked them to replace the board.
Hi there, tried to "autotune" PIDs on my Pixhawk which is configured to drive a V-Tail Quad. The V-tail Quad flies quite ok already but sometimes it behaves a bit unstable/nervous in the air - that is especially when it's getting hit by wind gusts.That is why I setup the autotune feature to CH7 on my Radio.CH7 is configured to a switch on my radio and I can see that it works like a charm in the radio callibration screen.However: When i flip the switch while flying in STABLIZE or ALT-HOLD…See More
"Thank you Tom. I have designed my V-Tail now in a way so that all 4 motors sit almost perfectly on a circle around the CG. Taking about the correct angle for the tail rotors: Some say 40degree, some say 30degbis the correct angle. This is a huge…"
"Thanks Tom. I can easily calculate the proper CG with my CAD, so i do not worry to much about that.
I was just wondering if there is a "defacto standard" how a V-Tail-Setup should optimally look like and which works best with the V-Tail…"
i always wanted to build a V-Tail Setup but i never did because my favourite FlightControler (APM) did not support it. Now I am happy like a child to hear that support has finally been added! =)
Right now I am designing my own build (which…"
"@McCray: Problem with ceramic bearings is: Their specs only allow very low RPMs (about 2000-5000rpms - that is way to low for a multicopter) + they are expansive like hell + it is difficult to get very small ones e.g. for motors in the 220x…"
"I did exactly that - WD40 on the upper bearing (you can't reach the lower bearing though).... and after each flight wash the copter in a padding pool full of sweet water... I even dipped the complete copter unter water and let the motors run at…"
"The idea of a waterproof BoxCopter is indeed nice and it really works quite well (yes i built one) - there is only one big problem that has yet to be solved: The motors are still exposed to the water. This is no pronlem in the first place since they…"
