Why do 4S 850mah packs basically cost the same as 4S 1300mah packs ? They have 35% less energy. Why only a couple dollars, if even, difference ?

I'm curious if anyone knows if its ok to find whichever resistors are inside and swap it for something a bit beefier(along with a heatsink for it to cool) Just looking for a faster balance charging or just balancing.  
I"ve already built a large resistor bank for external discharging but I kinda wanna have something for that balance charge
i realize the balance cables are 22 gauge so won't be able to do a masssive discharge, i just want a little more than its max of 16 watts atm. Also wondering if the software will let it discharge faster or not even if i change the resistor?
I haven't opened my own but looked at a first teardown videos and couldn't see where those resistors are, I had assumed it would've been more obvious large+heatsink, but im guessing it might be something tiny on the board itself so might be much harder to mod.  
Thanks for any input!

The footage at the end is pretty sublime.

Hello everyone, I'm in need of a little help. I noticed my quad wasn't flying well recently, there was something really off in the yaw movement. I connected it to betaflight and I checked the motors, the rear left motor did not spin. I switched to blheli config and got the error you can see attached. I disconnected the quad and I armed normally, all the motors were spinning. I'm pretty sure the yaw problem and this are related. So my question is: Is my ESC irreparably broken or is there a way or any chance to fix it?

The HDZero Expansion Module V2 bay with WiFi is now available to purchase from the HDZero web shop. It is $49.95 USD for the complete module, or a $29.95 USD upgrade price for existing V1 Expansion Module Bay owners who only need the updated V2 PCB.

What isn't clear is that the V2 circuit boards have a physical on/off switch on the board, but the white module bay housing of the V1 Expansion Module Bay doesn't have an L-shaped slot in it to accommodate the switch (see another post HERE). So I'm not sure if Divimath are going to send out a complete new module bay (including the new housing with a slot in) to those users for the discounted $29.95 upgrade price or if those users are going to have to butcher their existing housing to get the V2 PCB into it. EDIT: This question is now answered in post #2 below.

Watch Ryan's video at the bottom of this post to see how the WiFi functionality it works.

Divimath Wrote:HDZero expansion module is designed to add WiFi connectivity and standard analog receivers modules to HDZero goggle. The module has a module bay that is compatible with most of analog modules, such as IRC RapidFire and TBS Fusion. The module will be capable of video streaming to phone via WiFi .

HDZero Goggle’s real-time de-interlacer improves analog video resolution by intelligently combining interlaced fields (a first for FPV goggles).

The V1 module owners can upgrade to V2 with a PCB for $29.99.
The original order number is needed for verification. Please leave it at remark box.

For those in the US who are intending to fly >250g legally after September this year, Dronetag have a special one-day deal on their new Dronetag BS Remote ID module of $49 USD which is 40% off the normal price if you place an order on 22nd May 2023. After that day the price will go up to $89 USD. Each customer can order up to 3 modules at the discounted price.

See Bruce's video at the bottom of this post for an overview / analysis of the module.

Dronetag Wrote:Dronetag BS is the best Remote ID solution for FPV pilots, aeromodelers, and recreational pilots. BS offers affordable Broadcast / Direct Remote capability as defined by FAA and EASA. It is the smallest and lightest Remote ID solution making it easier than ever for aeromodelers and FPV pilots to comply with regulations while enjoying their favorite hobby. 

Package contains:

• 1 × Dronetag BS
  

External Bluetooth and Positioning antennas are not included, you may use your own antennas, or you can buy one of these:

• Combined Bluetooth + GNSS Positioning Antenna (U.FL)
  
• GNSS Positioning Antenna - Compact Size (U.FL)
  
• Bluetooth Antenna - Ultra Small (U.FL)
  
• Bluetooth Antenna - High Performance (U.FL)
  

The BS can be powered from up to 17V power input, or you can consider optionally using the small 3.7V Li-Po batteries (e.g., 50 mAh can run up to two hours). Batteries must have a JST SH 3-pin connector. 

The price of $49 applies only for orders placed on May 22, 2023. The official retail price will then start at $89. The number of pieces is limited to 3 pieces per customer. The delivery will be managed by the end of July 2023.

Description:

• Easy installation and compatibility with various aircraft hardware setups
  
• Real-time tracking and Remote ID compliant with the FAA rule

I have a mobula7 hd 1s elrs drone, a radiomaster zorro elrs controller, and hdzero goggles with foxeer wildfire analog module. I have the truerc nubby antennas in the foxeer module.
What kind of range should I be expecting?
Unobstructed on the street I got out to about 800 feet before I got concerned by the signal breakup (though I didn't push it to failure), and in more congested settings, with trees or my house between me and the drone, I was losing signal rapidly (closer to 100' away with heavy obstruction)
I saw on youtube that someone took their non-hd mobula 7 to over a mile away, how can I improve my range?
Thanks!

Lost in Translation!
This is a conversation I had with Geprc customer service

Hi Bro. I've done more damage to my TinyGo and the Flight controller no longer works.
I want to have a TinyGo with ERLS Rx that I can connect to different transmitters.
Can I buy a Flight controller and Erls Rx package I can put into my existing TinyGo?

GEPRC
Of course you can purchase ELRS 2.4G receiver and install ELRS receiver instead of the original receiver
https://geprc.com/product/geprc-taker-f4...t-12a-aio/
The new FC we used , Target is F411 AIO and use 4.3 CLI and firmware
https://geprc.com/downloads/tinygo/

Me
I see there's an ELRS option for that board. Does that mean it has an integral receiver? If so what antenna would you recommend to match the Diamond antenna on my Elrs transmitter?

GEPRC
You need install the ELRS receiver yourself

antenna , If you use the ELRS receiver , The receiver 2.4 comes with Antenna

Me
Is the advantage of ordering the Elrs option that I won't need a pull-up resistor for the rx?

GEPRC
No need, just the receiver

(I inserted a picture of the board here which is shown below and I arrowed something that looks like an antenna connection)

Me
Please could you tell me what this connector is for?
Sorry to be a nuisance but I'm trying to know what I am buying ?

GEPRC
this connector is for reboot FC and enter into DFU Model

[color=var(--primary-text)]What minimum firmware HDZero Whoop VTX has to have in order to work with nano 90 camera ? I have video with my current 7.68.127. Do I really need to upgrade to 9.0.12 (Rev0413...)[/color]

I have two quads with the Whoop Lite VTX, and both exhibit the following annoying behaviour.

1.  At any state of the battery, though becoming more likely as the charge depletes, a normally no issue with analogue knock (like clipping a gate on the way through) will freak the thing into rainbow lines, then seconds later it will go black screen but with Betaflight OSD. 

2. Once happened it will not self recover from this, short of power cycling.   Its not end of pack charge related since I can often reboot  and fly on for a couple of minutes.

They BOTH do this, fitted in differing quads. Clip a tree branch and you are blind, hardly acceptable behaviour.

It happens using my Transporter2 headset and with the HDZ goggles.


I often fly in Angle, and suspect the bump reaction throttle surge that gives after an impact is causing voltage sag, but the OSD does not visually show the level of sag I'd think needed. 

Anybody else getting this?  Or found a solution?
