46.5mm Tinywhoop

I wanted to create an ultra-small whoop.
I inspired by these two fantastic builds, and I've built my own drone.
Yokto Quad
Jellyfish

Here are the points where I aimed to differentiate and innovate:

Ease of Maintenance:
- The frame is easy to assemble, and a standard whoop canopy can be easily attached.
Versatility with Whoop Attachment:
- Equipped with propeller guards for safety indoors. Of course, it can fly even with the guards removed.

The flying experience is fascinating, providing a sensation similar to throwing small stones.
It offers linear flight with quick acceleration and easy changes in posture.
However, the challenge lies in insufficient thrust during turns.

Nice build! Its fun (and tricky) to build these things so small. My Yokto quad isnt my favorite flyer (not as much power as i'd like) but it gets the most attention! And you are right, it is not very easy to maintain. If i break an arm, its a 30 minute ~ 1 hour job to fix haha. Ah the price of being small....

I also have the same impression about the flying characteristics of small quads, and I can't help but feel dissatisfied with the flying behavior compared to a regular 65mm Tiny.

But I've always wanted to try a small build, and your Yokto Quad has been a great inspiration! Thank you very much!

I really like the concept and tbh you inspired me to start smth similar. However, I do think the battery placement is blocking airflow - regardless, if it works, it works! cheers mate

This canopy made by RC shop "helimonstor" in my country, Japan.
I love it.

It's a cute quad! I think the battery location is ideal.

Build a 5" Long Range Drone - Transformer Ultralight

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..
