Bravo 2" Micro

This is my second build, and since my first build was a 5inch race quad I thought i'd go with a 2inch micro so that I had something to fly indoors when the weather is bad or at night time!

Using the Elf 88 frame you've got yourself a truly micro build! It looks great without the prop guards, but the prop guards are handy when you're bouncing your way down the hallway or under the dining table :) The frame is tough, i've had some decent crashes and it hasn't let me down yet.

This was a pretty easy build, the eachine minicube anniversary edition comes as a fully presoldered stack, so all you need to do is mount it to your frame and then solder your motor wires to the pads and you're ready to fly (you're going to need tweezers and a good soldering iron if you want a neat job). I desoldered the buzzer from the top of the stack and mounted it at the back (to reduce stack height) and connected it up with some motor wire trimmings so it still works, then a bit of shrink tube over the buzzer and power leads to keep it neatly secured in place. Even with the buzzer moved, the standoffs that come with the frame are only 18mm tall and i couldnt get the stack to fit, so i added a 1mm m2 washer to each frame standoff to make the total frame height 19mm, and then lowered the stack height by another 2mm by removing the 5mm standoffs from the bottom of the stack and using 3x 1mm washers instead. If you're going to do this you'll need 10mm m2 screws to mount the stack from underneath.

The Eachine VTX05 camera with built in transmitter plugs right in so you dont need to solder anything to get the camera and osd to work. Only note is that you'll need to switch the ground and 5v wires around on your camera before you plug it in to your stack. You can find the wiring diagrams for both the stack and the VTX05 online so just doublecheck those to make sure everything is in the right order. I 'soft mounted' the camera with some rubber o rings which works great.

I've only flown this thing on 2s and im already impressed by the power, I dont think i'll even try 3s because i'm happy with its performance on 2s and I dont want to pump too much voltage/heat into this little beauty. On 2s it pulls off all the stuff a 5inch can do no worries if you take it outside.

Only flaw i've found so far is in the quality of the props, they bend and break easily so i'm going to try gemfan or dalprop 2035's. UPDATE I put on some dalprop 2035 props (see photo with purple props) and they are a lot better, tougher and quieter.

Fun to build, fun to fly and weighs only 67 grams! if you've got any questions just ask :)

p.s; i just swapped to dalprop 2035 prop's they are a LOT better, they dont bend or break and they are a bit quieter.

FUNETIC FPV   Oct 01, 2018

Just get 1106s(emax or hglrc, for example) unless you are building an ultralight

great build for what i was looking, was going to get a second hand drone for around the same price, but now thinking about it i better off get new parts and build it myself for the same price, thanks for sharing your build :)

Sorry.. I mean the the M2 srews! Do I need 8, 10, 12mm ?
Thanks alot for your reply :D

FUNETIC FPV   Sep 27, 2018 

oh ok, yeah i ordered the 10mm, they were just the right length, 8mm would also work. The m2 nylon washers are also handy because the standoffs that come with the frame are 18mm tall and you're going to need an extra millimeter or two in height to fit your minicube stack and have a little bit of clearance with the top of the frame.

Oh, and i've added a few more details about the build if you need them you can find them above :)

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..
