Goal: 5 inch under 250 gramms AUW with digital FPV
Frame: TBS PodRacer 5" (nice and priceworthy)
Approach for 3S: BrotherHobby VY 2004 Motors @3150KV
FC/ESC: JHEMCU GHF411AIO 4x30A
FPV/RC: Vista Nebula V2 bound to DJI Radio
Props: GemFan Hurricane 5125-3
Accidentally soldered vBat to GND on the Vista - bruzzzz - some magic smoke.
Vista fortunately wasnt harmed and works well after swapping cables.
8KHz/8KHz dShot600 caused weird turning maybe too many bad frames.
2KHz/8KHz dShot300 works smooth and nice now on those BLHs ESC.
My Turnigy Bolt HV 3S 850Ah are slightly too heavy for 250 gramms.
Tattu rLine 750 fit perfectly for an actual AUW of 244 gramms.
(look funny with XT60)
Used long M2 screws and silicone tubes to lift the pod for 8 millimeters.
I was wondering if the Motors were okay for the props and the battery voltage.
Now after the maiden I can say, that this setup rocks.

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..

You're lucky with that Vista, I did the same thing with my JBF7 Flight controller and it didn't fare as well.
Vistas and AirUnits do have protection circuits, which FCs and ESCs sadly don`t have.
The short welded the wires to the Vista. It wasn`t possible to desolder them. I had to cut em off and soldered on the weldings.
