I love the way this lightweight build flies. There is a magic about 40g 2S builds with 2.5" props.
It uses my 3D printed frame.
Has an optional prop guard.

just curious. why not using 1104/1105 motors ? 10A esc for sure can handle them.
the frame looks like you can put a whoop board on it. can it ?

I like the 1103 for 2S builds as they are super lightweight. This build is about 40g.

I may try 1104 at some point to compare but I find 1103 are a sweetspot for 2S. I tend to move up to 1104 for 3S.

This frame doesn't fit a Whoop board but I am do have one. I will post it soon!

Does it really fly well with these props? I never tried them. A two-bladed prop like Gemfan 3025 is usually my first choice for a drone like this if you can fit 3"

Different. Honestly I've not flown the Genfams for a while but I preferred the Emax when I first swapped. f I'm honest I can't remember why! Though I think they are far more durable...

They are far more durable, and really quiet. But if you're going for more speed, they just aren't aggressive enough pitch. for a build like this though they'd be perfect. for faster, and more durable, i like the hqprop 2535.

I do have some of the HQs - I'll give them a go 😀

I like the arm design!

Taylormadearmy Jan 03, 2019

Thanks! I wanted them to be strong/stiff, but to have as small a cross section to the airflow as possible.
Printed in polycarbonate its been indestructible so far...

I'm new to 3D printing so I've just been using PLA. I'll have to try the polycarbonate

As long as your printer can get hot enough (297C is what I can get to) it's not too bad to print with once you know the secret...

What is the secret you ask? it's about having a high nozzle pressure. So wide extrusion widths and tall layer heights... (0.7mm and 0.3mm for me).

This frame would break if you sneezed on it if printed in PLA I think...

Jun 21, 2021

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..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

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..
