Whishper v2

I tried 4s on v1 and once i got on the throttle, it stuck .... After killing the power and falling to the concrete, I broke an arm on that toothpick frame and stripped a motor. I am running a geprc 5000kv, a flywoo 5150kv, and two flywoo 8150kv 1204s
if another one of these motors breaks or strips, i get to buy an new set :D
I wanted to try this phantom frame for a while and i prefer the cage and top mount battery setup over the camera on top canopy.
I gained 17g in the rebuild.
v1 used 2" 5 blade props, v2 is using 2.5" 8 blade props are pretty heavy. new frame also added some weight.
Its even more stealth than v1.
like my other geprc frame.. its super clean. They make quality frames
2s is nice for cruising
3s is optimal for fun
4s.... not until i go out to the wilderness but its gonna be tried :D

SO... you are telling me that this flies with 3 different kv's, across 4 motors? Is that right? I have a crazy request: can you make a vid of your fpv feed, with the blackbox overlay showing the motor values? I just want to see how much it's revving each motor!!
Any way you can show this would be so cool for me, I want to know which motor is on which corner too
I see that one of the 8150's is motor #2
I see that the 5000kv is motor #4

1 & #3 are an 8150, and a 5150, but I can't tell which is which from the photos

I would think that an 8150kv motor would require a different rythim from the ESC to maintain the same speed as the 5000kv, and i'm curious to know which draws more power

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..
