"Jared: Sounds like a dream come true! The ideal size is "no wider than 51mm and no higher than 35mm". The length could be around 150mm. I need 4S at about 40A cont with peaks of 90A,  I'm not sure I understand everything though,…"

"I think many of us are using 4S 4500mAh Size lipos, in for instance the QAV and TBS quads. It is feasable to build one of these in the same size, and what would the ratings be in terms of continuous power (Amp) and mAh? Also price? :) Kind…"

"Is there a similarly simple option for making a Bluetooth/Telemetry bridge? I want my 500+ meters range using my 433Mhz Telemetry Modules, but I don't want to connect it via USB to my phone, I'd like to use Bluetooth for that. Iv'e…"

"Additional info: The voltage sensor works pretty well. I'm using the whole thing over telemetry as well as with the minimOSD. It's the current I'd be interested in reading properly."

APM Power Module, doing it wrong?

Hi,I'm on my second APM build. My first was an Octocopter with an APM2.5+. I got the powermodule working but it never displayed the values quite right, it would oscillate up and down and just show unreasonable numbers. Got it replaced on warranty, but no change.Fast forward a year. Built a new QAV540G with an ebay APM 2.6 and "Ebay" Power module.It works great, but same thing, shows wierd values. While standing still at the ground, unarmed: 0.1 Amp, up to 12 Amp, 4 Amp, 0,5 Amp etc... up and…See More

"Rolf,  thanks, you were right, it was the cable! Your suggestion to hook up only the radio got me thinking. I exchanged TX and RX pins on the APM end with each other, and then also exchanged them on the Radio end. After that, 100% difference.…"

The video says it all. Better than 3D, steer the video yourself!
