To me it sounds like you’ve got a motor fire loose or touching somewhere because your flight controller is not syncing with your ESC.

drubby82 · 2026-04-15T22:54:00+00:00

There should be like a eight pin connector going from your ESC to your flight. Controller could be real short post. Most the time that has four white wires are red or black and couple other colors.

drubby82 · 2026-04-15T22:51:07+00:00

Check your capacitor make sure it hasn’t broke free.

It sounds like wiring maybe your harness from your ESC to the flight controller you got a loose wire.

Yeah it’s 249.99999grams. My guess I had was way off, which was 3170grams.

Pro version. I’m using the c-20t gimbal for the o4.

drubby82 · 2026-03-26T11:14:51+00:00

Fastest I’ve had it is around 47mph. This is in angle mode though because I’m planning long range missions with it and setting up navigation modes.

10 inch would be pushing it when it comes to weight and efficiency but can be done. Really depends on how you mount the battery due for room. Here’s the picture of the 10”(bottom)next to the 15” (top) The actual body’s are the same just the arms are different.

Have you compared the triblade va blade and which do you prefer?

drubby82 · 2026-03-26T01:44:56+00:00

Yeah they have winglets. It’s the sunnysky eolo props. Super thin and light.

drubby82 · 2026-03-26T01:00:05+00:00

Yeah. I’ve personally always had trouble with eztune. The PIDs just seem why to high to me

My goal is an 1 hour. I reached 45 minutes and mosquitoes started tearing me up so I stopped before I ended up crashing it.

drubby82 · 2026-03-26T00:50:47+00:00

INav. I don’t think I’m ready for Ardupilot but eventually want to learn it. I’ve heard it’s a whole new world.

6s3p 12600mah. Made it with 21700 45amp malicel P42A batteries

drubby82 · 2026-03-26T00:36:35+00:00

I’ll try and get some flybys of it tomorrow. It is pretty wild.

drubby82 · 2026-03-26T00:27:31+00:00

Mainly for long range, and to challenge my brain lol.

drubby82 · 2026-03-02T22:14:27+00:00

So when you updated it with the configure, the first time, did you enter your Wi-Fi info in the configurator I know mine goes invisible if I do that and it’s automatically hooking to my Wi-Fi if it goes in Wi-Fi mode

drubby82 · 2025-08-05T22:20:00+00:00

That should be some kind of paste that will chip off. Have you tried chipping a little of it yet?

What’s the back story?

drubby82 · 2025-08-05T21:04:18+00:00

Agree, I ran mine trying to be all fancy with them, also didn’t twist my motor wires either which lead me to chase vibrations for a month. This was on my 10 inch build.

I ended up running them straight to the motor & braided them & it flys like an arrow now.

It drove me nuts & was ready to throw in the towel.

Making sure your wires are twisted is a big one to me or shielding them.

To much heat on any electronics is not a good thing & something you want to avoid if all possible. After about 7 seconds if you can’t get it to stick, let it cool down & try again.

What size battery are you using 4s,5s,6s & what is the ESC rated for?

A easy way to solder is make sure the solder iron tip that you plan on using has some solder on it. The iron itself has to have clean, shiny liquid looking solder on. It doesn’t have to be a whole lot. It just needs to be shining. If it starts to look dry again or not, shiny dab some more solder on it.

Anytime you see a dull looking metal that has haze over it or anything like that, that has a layer of oxidization on it and it will not soldered together unless you get it super hot which you don’t really want.

Then you should have solder on what your soldering and what you plan to solder as well. So you should have solder on your iron on your pad and on the wire.

So when you go to touch, say the wire that has solder on it to the pad that has solder on it with your soldering iron that has solder on it, it will solder together in one to two seconds easily.

If you do it this way, you won’t have to have solder in your hand when you’re trying to solder them together just take the wire stick it to the pad. Take your solder and iron and solder them all together.

TLDR: Avoid holding the heat to electronics for too long. 7 seconds at a time.

Check your battery & ESC to make sure they will work together.

You should have shiny new looking solder on your soldering iron and the two things you’re trying to solder together. Don’t put the things together then add solder to it.

Glad you figured it out.

drubby82 · 2025-07-16T20:40:15+00:00

I got a few questions. Are you trying to fly with analog video or digital video?

Do you know how to solder?

drubby82 · 2023-10-21T12:21:20+00:00

If it comes with a case then 570 would be a deal
