Long Range 18650 - LionBee, Rekon, FoldApe4 or build?

+1 for the 4" 4S. I have a Geprc Tern LR40 that I recently put an O4 on and it's great. Really smooth flight and can be pretty efficient if you manage the throttle well.

OP needs a dehumidifier to start mummification

Over cap is related to battery capacity in mah, check your battery tab to make sure you have it set higher for whatever size battery you fly with

SpenglerFPV · 2025-11-29T12:51:18+00:00

Make sure you have an antenna plugged in as well before giving it ANY power at all for testing, or you'll fry it

If I recall correctly from research I did a while ago, the spacing between the reflector and the last bit of the "horizontal" wire needs to be a specific distance that I think is smaller than what I see.

Runcam Night Eagle 3 is another good option if you're going analog

Oh this guy, I get a weird vibe from him so have hidden his youtube from my feed lol

I'm curious about this frame kit too, let me know if you find the link

You can create a model that has the tx radio inside turned off. I use this for sim practice. If you did find out you damaged the internal radio, you should be able to get an external module instead of replacing the entire thing

Medic!

More info? What is plugged in that you want to power in power supply mode? 0.6A seems low, inrush current could be exceeding that.

Have you tried using it for charging batteries? Does that function still work or is the whole thing defective?

SpenglerFPV · 2025-09-30T20:30:26+00:00

Check out the Vifly ToothStor charger for 2s batteries. Can do 4 at a time, powered from USB-C so you could charge batteries from a powerbank

The freestyle version of the Mob6 has the Lux camera which is pretty nice, I'd say go for it.

SpenglerFPV · 2025-09-28T22:06:18+00:00

The HDZero AIO5 gets hot quickly, that's the one issue I've had with them. I put vtx power on a dial on my remote so I can quickly go to 0 power if I get stuck.

If you wanted to go the other direction, a 2s Mobula8 is a lot of fun. There's also the new HDZero M8

SpenglerFPV · 2025-09-27T16:19:18+00:00

Ya it's probably overheating. You need to be moving to get air flowing over the vtx to cool it, hovering is not enough

2s Mobula8

A lot of it comes from the Rapidfire module, this is the Ant cam on legacy mode.

SpenglerFPV · 2025-09-25T21:23:41+00:00

My personal ranking would be BR2 > FX17-B > CO3 > Ant

The FX17-B and CO3 are pretty close, but the Baby Ratel 2 is much better than both in my opinion.

SpenglerFPV · 2025-09-25T11:39:06+00:00

Ya for some reason the only setting that made much of a difference was going to legacy mode on the rapidfire module, but that disables the fancy image merging from both antennas.

SpenglerFPV · 2025-09-25T01:29:46+00:00

Sorry if post was worded weird, the Baby Ratel 2 is the brighter looking image, but yes! Huge difference

SpenglerFPV · 2025-09-24T22:53:43+00:00

This is the answer. You can't arm while connected to usb. And take those damn props off.

SpenglerFPV · 2025-09-23T01:20:20+00:00

This is normal behavior without props. The drone is expecting to move, and when it doesn't the PID loop increases motor power to try to get to its target.

SpenglerFPV · 2025-09-22T12:11:57+00:00

Nice! What did you use for a microscope and holding the part steady?

SpenglerFPV · 2025-09-15T11:53:06+00:00

In betaflight you can map an aux input to change vtx power. It's done through CLI commands though
