▼ UMX WACO Telemetry Issue

3/11/2024

While programming the DX8 G2 radio to control this plane, I noticed the Receiver Voltage was displaying the voltage for 1 cell when using 2 cell battery pack.  Thinking it was a setup or radio issue, I checked it with another 2 cell plane. 

Planes

	EFLU6950  - UMX Turbo Timber 
	EFLU53550 - UMX Waco Red/White


Battery 

	Venom 2 cell 7.4V 300mAh
	Current State 7.5430 V 26%


Radio
	Spektrum DX8 G2

The battery is at 7.5430 Volts, 26% charge as seen in the following image

When plugged in to the UMX Waco (Red/White), we see the radio displays 4.2V on two screens, Telemetry and Min/Max, which is incorrect.

Screen :  Telemetry, showing   Rx: 4.2

Screen :  Min/Max,    showing   Rx: 4.2V   4.2V

I would expect to see about 7.5 Volts.

Checking with another plane, the UMX Turbo Timber, we see the correct voltage being displayed via Telemetry screens.

Notice 7.2 Volts as what is expected

We see the same on the Min/Max screen.

I have a call in to Technical Support and will update this when I have more to share.

Update - No response from Technical Support as of 8/2/2024.

---

Final Update - the voltage dispalayed is the voltage going to the Rx section on the curcut board, not the votage going to the curcut board.
