Wow, you sure did well fitting all that in the frame! I love the Micro Apex frames, but I've only ever flown analogue where it's easier to get everything in. Nice setup and I bet it flies beautifully!

Thank you for the compliment on my setup! I'm glad to hear that you enjoy flying with Micro Apex frames. It's a nice compact and lightweight but also durable frame. As you mentioned, it can be challenging to fit everything in a small frame, it took a lot of time ๐Ÿ˜… I hope you have fun flying your analogue setup, and perhaps you'll consider building a digital drone in the future!

Wow, that 6S pack looks nuts :D The parts list says 2004 motors but I think they're 1408s in the photos, right? How are you finding them with that kind of weight? I went from 2004 to 2203.5 on my (fairly heavy) Apex 4, but still not quite happy with it.

How is your buzzer attached to the mount? I ended up stuffing mine in behind the camera but it's kind of awkward to get to.

Cheers! Happy flying :)

Thx ๐Ÿ™‚ You're right, I made a copy & paste mistake. That are 1408 2350KV motors, I've updated the parts list, thanks for the hint. They perform very good, this quad is now one of my favourites. I'm always looking for the size of the lateral surface, when I have to choose motors for a new build:
So, 1408 is way more powerful than 2004 and 2203,5 - and 1408 is also lighter. So, if you are looking for extrem power and good acceleration instead of efficiency, than take 1408.

I mounted the buzzer with a tpu mount, which I have desingned. It's attached with heat shrink to that tiny TPU print. I prefer to mount the buzzer outside the frame, because I had several times the problem, that they start to buzz and it is impossible to turn them off, when they get wet or after a heavy crash. It's realy annoying, therefor I stopped using Vifly Finder 2 Buzzers, because I had at least 5 times this failure. Now I'm using the HGLRC Soter buzzers. So far this problem didn't appear anymore, but to be sure I still prefer a place where I can easyly remove them and also replace them. I've added the stl location to the parts list and also a link to the buzzers I use.

Cheers! Happy flying ๐Ÿ˜๐Ÿ––

Cheers! I have spent the afternoon copying this (though I don't have a proper mount) - I just managed to wedge/foam tape my buzzer under the antenna mount. Now I don't need to carry a small stick to poke the button when I take the battery out ๐Ÿ˜‚ So, thanks for that idea!

I'm quite keen to try the 1408s but with an 850mah 4S pack I'm getting around 4 mins flight time and my Apex is quite chonky at about 350g or so. Not sure how much less efficient it would be with 1408s. But... it might be more fun :D

Thanks for the reply man, appreciate it.

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..
