Wanted to build a discrete freestyle quad as my 5" was feeling a bit Obnoxious.
Aim was to build somthing that would fly similar to a 5" and be able to take beating. ImpulseRC's new apex micro was the obvious choice with a solid 5mm frame.
This thing rips!
Get around 3 and a half minutes of mild aggresive flight time on a 4s 750mah. (Tattu R-Line)

Nice build! I'm actually thinking about this frame for my son, because he's been flying the TBS Source Micro 2" with 1103 motors on 3S, but I'm tired of replacing motors! The motors are just so small and the frame arms don't offer any protection. I got CNC Madness to cut me a couple of spare bottom plates, because he's already broken one. The Micro Apex looks like a tank, so I think he'd be able to spend more time flying and less time fixing. Those Rotorgeek 1407's look very durable also.
Curious, is the 3.5 min flight time in the winter (cold temps)?
Thanks man! I was previously flying the Geprc Phantom frame but had similar problems with the arms motors breaking to easily.
Got the apex so I could have a micro beater and I have to say its worked great. I've had a few hard concrete slams and the thing has held up. Frame and 4mm arms are solid, so would highly recommend. Same story goes for the motors, I live near the rotorgeeks store in toronto and wanted a solid durable motor, obviously going for the more durable option means more weight and these motors did push the build just over 250g. But they are solid and very well built. (Rotorgeeks have actually discontinued manufacturing these motors, but still have a fairly large stock of the motors and spares).
As for the flight time, yes thats winter temps, around zero degrees celsius.
Also ran Genfam 3052 props today and they are what ill be using from now.
Thanks for the info, it sounds like a good frame. I'm in Niagara region, but Rotorgeeks ships here pretty quick, so I like the idea of ordering motors from them incase I ever need a replacement. I didn't know those were being discontinued, so that's good to know.
Do you think it should be pretty easy to keep it under 250g with an analog setup? I've got a small VTX and then I'll probably put in a splitcam or Caddx Baby Turtle. Would you say that the 750mAh is the minumum or do you think 650 would be ok in the warmer weather? I think for him I'll probably keep the props fairly tame.

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..

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?
I'm also interested in just how loud this is compared to a 5". I love my 5" but I do feel a bit self conscious about it sometimes :-D Made a 3" toothpick which is great, and much more usable in smaller parks, with great flight times (4-5 mins on a 450Mah 3S) but doesn't quite have the throw. I'd love a smaller freestyle basher so I'm considering a 3/4" build to join the family.
