FlyFox No.5 - Missile 135

Another 3" build based on the rarely used FlyFox's No.5 frame, called "Missile 135".
It has all the candies: 4s power, 350mw VTX, full telemetry, video and PIDs controlled via remote (lua-scripts).
The 3mm frame is quite strong and sophisticated - with just one down-side: the motor protection is de-facto non-existend.
I did shorten the Mamba stack by using thick m2x16 titanium screws and m2 nylon nuts between the PCBs. You can see the last two close-up pictures do compare original Mamba stack nylon-space and my shortened variant.

A speed test resulted in 144 km/h (89mph) top speed.

Durable frame ? I've read a couple ppl have had the motors break off around the screw holes

Indeed, it's so-so. Ive cracked one bottom plate exactly around the screw holes, yes.
The stiffness and 3mm thickness are good, just the spacing where the inner motor screw holes are located is the weakest point of this frame, IMHO

Thanks for the reply. A common issue with the frame then.

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..
