Thanks for the shout out Bartman. I actually found another person who is having INAVerr stuck at 255 with a Pixhawk and CSGShop M8N. He says he doesn't get the "twitching" that I observe, so who knows, maybe I'm imagining it. I flew it the other day. In stab mode it was fine (no simple/ss...

platform: Pixhawk, CSGShop Neo-M8N GPS (same error with 3DR LEA6H GPS) If anyone knows or has an idea what may be causing these INAVerr, I'm all ears. I've posted at DIYDrones, RCG and APM Copter support. The latest reply from Randy was: I should be more clear. The PM message's long-loops...

Correct if wrong, but the length of the battery wire is also a factor and the weakest link in the wire will be the hottest point.

I have the external LED on my Spy. It cycles through the different colored lights, turns blue, then green when GPS locked. If something goes wrong, the light flashes a different color such as yellow. That's the only info I can give. I drilled a tiny hole in the support at a slight angle and...

Good luck with your new build, and be sure to post updates. I'm going to keep going on this Spy for a while yet as it is flying well (and too much work/$$ into it to can); would like to get different pitch props for the top, but other than T-Motor 14x4.8, I couldn't find any TM style 14" with...

Those I know using such sensors don't use sonar. Here's a few posts at DIY http://diydrones.com/profiles/blogs/using-lidar-lite-to-sweep-an-arc-for-sense-and-avoid?xg_source=activity http://diydrones.com/profiles/blogs/precision-land-arducopter-demo?xg_source=activity...

Do you have a link to that mount? I have one for the wires, but not the square antenna. I 3d printed these already, but are not practical for my setup: http://www.thingiverse.com/thing:258146

Well you know someone now :) It was one big PITA finding an ESC that works [mostly] correctly with even the 515 motors. Only the HobbyWing Xrotor is not giving me fits.......yet. I know a few others that use non-KDE ESC's. Here's the funny part: the Maytech ST OPTO was supposed to work out...

I've seen a few guys with the Kylin but no word on if they're having problems with them. Depending on the exact size of the tube vs the machining on the mount, I see your point. I'm seriously thinking about going to a different frame, maybe even X8 (have enough motors), or build a standalone...

The ones drawing the least power are the hottest? That seems odd. The ESC's on my Spy are in the arms (gag) about midway between the frame and motor; the motor mounts block convective heat flow so if keeping this Spy is the plan, different motor mounts are a must. The more I look at this design...

Don't be surprised if those motors outperform ECalc predictions by quite a bit. It's fairly close on 50% throttle, but the rest is less than to be desired. For my Spy 750 Y6 w/515 motors ECalc was way off on their beta co-axial, so I use the flat calculations and add about 5% weight. Predicted...

Wow that is a monster! A work of engineering too. Very impressive. I have a SH Spy 750 Y6 with KDE 2814XF-515 motors. AUW 3.1kg; am about ready to ditch the coaxial stuff, too much monkeying around to make them efficient. You did the right thing getting the KDE ESC's for those motors. Be...

I feel the same as you, and don't know about the Trooper, but the Sky Hero Spy motor mounts are not supposed to be tightened fully around the arm; there should be a gap there or else it puts too much stress on the screw bosses and they'll crack. At least you didn't lay down $500+ for a Spy! You...

Dang those are big motors. Are you going to use the KDE ESC's?

What ESC's did you get? I went through 3 different SimonK ESC's until finally got HobbyWing 40A OPTO. They work great and flight time increased, run cool. They fit in the tubes, don't about the Trooper arms though. I have Sky Hero Spy 750 and KDE 2814XF-515 motors, Pixhawk FC. What I (and...

No doubt the KDE ESC's are probably the best, but there is no room in the Spy to put them and KDE recommends against installing in the arms although the HW don't seem to get hot. There must be some inherent design in these 515 motors (I would assume other KDE models) that makes most SimonK...

I installed the HW XRotor 40A ESC's today. All I can say is, after trying 4 different ESC's, the HW's are the absolute best for my Y6 using KDE 2814XF-515 motors. No stuttering on takeoff, and the motors sound much smoother. Hover test gave 1.5 more minutes flight time in 43 degF 10-15 mph...

I ended up putting the 2814XF-515 on a Sky Hero Spy 750 Y6. Pixhawk FC 14x5.5 CF TM style props The problem from the beginning has been ESC's and sync problems. The short of it: 1) Maytech 30A OPTO ST- FAIL; could not get 6 motors to spin out of 8 ESC's tried. Took one 3DR 20A BEC and...

Rob, Should I worry about my setup using OPTO ESC's? I've posted on DIY and ******** with no reply. As this is my first multicopter using OPTO's, I'd like to prevent any electrical issues. Why wouldn't the UBEC accomplish the same thing as it is grounded to the battery? To the OP, what if...

As I'm reading this, my wiring is incorrect and should splice into the PM and "loop" it through the power rail? Why does it need to go to the Main Out? Suppose you have an 8 motor copter? I was under the impression any of the remaining 'Main Out' or 'Aux Out' is ok. Here is my wiring. I need to...
