That's a strange image there. Why not show a photo of some of your parts if you haven't completed the build yet?
No, that's not normal. It's showing battery voltage of only 3.53 volts! You need to calibrate the Battery Monitor. There are two attributes: voltage, which you can determine from a multimeter or one of those monitors you connect to the balance leads. The other is amperes per volt. This one requires you have a battery charger that tells you how many ma are returned. After some flight, charge the battery to see how much ma used...this is actual. Look at the APM log for CurrTot; the max value is 'measured'. Divide actual / measured and multipy that with the current value (default is 17) to get the new value. Then your amp draw and current consumed will be accurate.
That's pretty significant to effectively use those battery failsafes. My 'amperes per volt' setting was wrong recently and led to a crash. I was mere feet away from landing trusting the telemetry output that I'd used 5500ma of an 8000ma battery. In reality, I'd exhausted the entire battery and it pitched into the dirt dead.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

Are you going to use the stock CX-20 ESCs? You may need to extend the wires to fit on the longer arms and I'd suggest wrapping them in shrink wrap tubing to protect them. Personally, I replaced them with a set of cheap 30A SimonK ESCs.
YES, I will use the stock ESCs. I plan to later, but want to get it in the air first on the stock ones and do round two of upgrades once my learning curve improves.
Can you load some pictures?
I will once I get the kit, should take a week i guess (slow boat from china)
After the crash I am trying to assess if my issues and I get the following reading;
Can you please evaluate the following from the image
1) Battery readings seems off
2) GPS - i am out on the balcony
GPS hdop seems fine given only 6 satellites locked on. Try uavforecast.com for your location to learn how many satellites to expect. Be sure to uncheck the box for GLONASS unless you have a M8N gps unit.
Get the kit yet? How's the build coming along?
