When i got the email of the latest frame release from Impulserc , I knew i couldn't resist it. I'm a fan of 4" and Micro Apex 4 looks a lot more proportional next to the 3" so the choice was easy.
It's a quality kit and a real step up from Micro Alien/Reverb which are super tight for build.
I went with Nebula Pro for slight weight and cost saving. As for the motors, i really wanted T Motors 2004 but there's no local stock and I'm too impatient so i got some HGLRC Aeolus 2004 as used by Dave_C Rekon Micro LR 5". They look pretty slick in green.
Dry weight 218g so no sub 250g here.
Here's the link to the impulserc official antenna mount file on Thingiverse.

Had a few packs yesterday and it's a great flying quad with minimal tuning needed on stock BF 4.25

How loud is the drone? Also i'm thinking on going with 1404, 1505, 1606 or 1408 motor (inspired by babyhawk hd 1404, maybe also run 3.5inch props) you think that would work well enough?
Sweet build man, looking to do something similar! Do you think there is a way to get it under 250 grams with the vista? Perhaps lighter motors (though these seem pretty light already), ditching the protector and using an AIO FC/ESC board, but not sure if that will cut down the weight enough.
Really like the build. How do you like the 2004 motors on the 4in frame? It looks like they are very smooth from the video.
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..
Read moreWith 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..

nice job man. have you upgraded to BF 4.3 on this one? reason for the ask - I'm just getting around to replacing the analog components with Vista and curious on your pids and filters. coincidentally mine is now identical to yours other than the FC stack (HGLRC on mine).
Thanks. I was still on BF 4.26 when I built and recorded the videos. 4S PID were on BF 4.2.6- Roll 46 .95. 40, pitch 50.100.46, Yaw 46 . 100.0
RPM filtering , Dshot 300, gyro filter reduced slightly.
I had updated most of my 5" to BF 4.3 so I will do the same to Micro Apex too and try it out.
thanks for the reply! I built mine analog when the frame first came out. at the time I was moving to digital and never really flew the micro apex (or tuned it). now I'm finally getting around to installing the caddx Vista and see how this thing performs. I am going to try your suggestion with BF 4.3 as soon as we get some better weather up here in the Northeast.
