This is my first micro brushless build. Im still waiting on the VTX but I hope it will arrive soon. The build itself was quiet interesting because all the parts are way smaller than the parts for a 210 quad. I had problems with the stock wires of the 1103 motors (they are really bad tbh) So I changed them. The Kingkong Piko Stack is quiet nice and has a easy connection bridge. No wires required. Now its the time to tune this beauty and wait until the rain stops...

Here is the maiden flight. Pretty impressive if you ask me:

Hello, can you Tell me your configuration (pid, filter, better cli diff and betaflight Version) i need this for orientation for my Racer. Thank you

Hey! Excellent build...for that price, I guess that this could be a candidate for my first three inch quad.

Quick question-do you need a PDB for this thing? Your parts list doesn't include one.

BeatMeFPV   Aug 18, 2017 

Hey sorry I answer so late. No you dont need a PDB. The ESCs are AIO so you get the power for the FC directly from the ESCs

I wouldn't hold out for that vtx. Go for the Eachine VTX03.

I am actually using this VTX and explained how to make it work properly in my own build:
1/ You will need a reliable BEC (I added an external UBEC)
2/ Do not even try to run it on 200mw
3/ Blow some cold air to the VTX until you've managed to reduce its output to 25mw (default output is 200mw)
4/ Upgrade the firmware to MWOSD VTX branch and use it together with the free MWOSD GUI R1.6

That's a lot of tinkering but it works fairly well for me

Yea, it is super easy to burn up the Innova clone, which I why I go for FCs with built-in Betaflight OSD and a VTX03

raemin   Aug 12, 2017 

I agree yours is a much more sensible setup, but if you want all bells and whistles, the FCs with betaflight OSD do only have one single UART, The OSD is not graphical, and you cannot change VTX settiings from the OSD. On top of it I wanted dRonin as the new filtering makes the second loop (i.e all related to horizon and leveling) much better, so PikoBLX + Innova was the way to go. I must say the innova on 25mw produces less video noise than my TBS unify V2, and range is more than enough for a micro quad!

All in all, given current price (<$15) and availability of good firmware (MWOSD VTX), we should consider this one again.

Note: if one fry the video component, the daughter board can be sourced for $5 (https://www.banggood.com/FPV-5_8G-200mW-32CH-Wireless-Audio-Video-AV-Transmitter-Module-FX758-2-p-980317.html)

Well done! You should try cutting those props down to twin blade and see if you like it better. With 10,000kv motors i prefer the feel of twin blade and think it lets the motors shine a bit more.

Interesting. How do you cut them down though?

Complacent1   Aug 05, 2017 

Cut them as close as possible with small snips then use a sanding dremel or file to finish it.

BeatMeFPV   Aug 06, 2017 

I have to because I break so much props I have to cut them to twin blades :D I will report if I feel any difference

That's a pretty nice little setup there. How do you like it?

BeatMeFPV   Aug 05, 2017 

Im super happy with it. Its a little rocket :D I also added the maiden video in the description

Whiffles   Aug 05, 2017 

Awesome, looks great! This is certainly a tempting build.

I really like this build. I may have to copy it. Good price point too.

This is the 3rd revision in the "Wizard Killer" series of builds based on the Martian II frame. The original Wizard Killer was my response to the successful Eachine Wizard RTF quad. The Mark III supersedes the more budget oriented Wizard Killer Mark II and is the most featured packed, simple to build and powerful of the three. The base weight with props is about 326g and fully loaded with a battery..

At last, the Topsky F7X V2 is available. This is the updated V2 release which came 3 months after the failed V1 model from October, 2017. V1 had several issues and most reviewers declared it an utter failure. Did Topsky fix the issues and are these worth buying? Let's find out. On paper this sounded like a wonderful new goggle. Unfortunately we were let down. The displays exhibited ghosting, the..
