this is for those 1s enthusiasts mostly.

Kingkong 76mm props have 2 main problems
A. they have 1mm shafts. don't try to drill it out to 1.5mm. you'll cry trying.
B. the mounting holes are not through which make props sitting on top of the shafts and easily bend in crashes.

i've just figured out a solution.
i use a countersink bit ( bought from CNCmadness. it's for making countersunk holes for frame. it's very sharp. you can use it by hand )
to drill on the top of the hub until it meets the hole. now props can sit right on top of the motors. and that would make it hard to bend shafts in crashes, even when they're just 1mm shafts. and i use superglue to hold props. it works out pretty well for me so far.

0.3g/each prop, that is very light, the lightest 3in props which make some powerful 1s setup.

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..
