Hi,My quad is running on Pixhawk and I use a FlySky TH9X radio (typical DIY Quad kit from 3D Robotics). The firmware is ArduCopter v3.1.5.This morning, my quad started flying away (it might have been…Continue

Long distance milestone for multirotors?

Started by Eric. Last reply by Brit Davis Jul 17. 9 Replies

I have seen a few users with "100 km" badges, and I believe these were all achieved with fixed wing platforms. (Right?)I am wondering... what are the longest distances people have been able to cover…Continue

Forward flight -- how fast is too fast?

Started by Eric. Last reply by Eric Jul 16. 15 Replies

Do you have a multicopter running APM, and do you use it for waypoint missions? What do you have WP_SPEED set at? The default is 5 m/s... Anybody had luck flying up to 10 m/s or higher? How about in…Continue

Hi, I am trying to pair 2 air modules of an old 3dr radios, does anyone know how to accomplish this?

Does anybody have a link to the Power Module schematic?  Mine isn't working and I want to know why.

Thanks in advance.

@dr0n3droid My problems started here:
Now I think that I should have kept those clones and just transplant the voltage regulator from the old (original) PM to the new clone. Now I have none. I've sent the clones back and have refunded.
You just can't know if it's genuine or fake until it's in our hands, cuz those stores for sure don't say it's not the real thing. And the shipping costs for tiny things, gosh!
I think I'll stay here for today!
Thanks again dr0n3droid!

I keep that CC BEC around for situations like this. There is no I&V monitor, but but I can still fly.

@António I feel your pain.
I busted another PM yesterday in a rover crash. That's two now. If I break 3 more it might be worthwhile to fix them. I found the part I need.

$6.77 seems reasonable, but $48 for shipping? Something is wrong with the system.

@dr0n3droid Thanks again.
I'm starting to consider this option, attopilot+voltage regulator, for I'm frustrated in trying to buy a PM in europe, instead of trying to go for the higher voltage LiPos. It's the third attempt in buying one PM, and 2 were clones without the voltage regulator, and another went missing in the mail. Most of the best stores in here have it out of stock. I dunno why.

I'm feeling I'm being forced to buy it directly from 3DR, or try this new/old approach. In the while it's been week that my hexa is grounded. :-(

This is what I used before 3DR started making the PM.

Check your LHS.

@dr0n3droid Thank you for the speedy response.
Would you be kind to show me/us a link to one of those kind of regulators? Just as as an example. Perhaps it might be simpler to get one than I though.

Thank you again in advance.

Attopilot is for measurement only. What's missing is a voltage regulator to give you +5v for APM.
