I think the BBB 6000kv motor was too much for the Emax stack on 4s. It flew fine during my test flight in the garage but once I took it outside for the first FPV flight it just died within the first 20 sec. This build with the BBB 6000kv motors has failed. I had so many problems that I do not even know what was defective.
Problem #1, the flight controller was acting very strange. When I plug in the computer it would only work once. I would have to restart the computer in order for the FC to connect to the computer again. I happen to have another diatone Fury F4M flight controller and when I plug that one in the computer it works perfectly. So, I swapped the 2 boards out and things are happy again. But before I swapped the FC I also had another issue.
Problem #2, Motor #4 will not turn. I need to do more testing on the motor to determine if the motor is really dead. When I go in to butterflight to test the motors, #4 will not spin. I know it is getting a signal because the motor will cog but not spin correctly. It is possible that the FC was the cause of this problem, but I end up swapping all the motors out because I did not have a spare motor. After switching the FC and Motors, everything is working correctly.
I did a test flight in the garage and everything went okay. But when I went to the park to do the maiden flight, I made a big mistake and did not test my FPV setup. The OSD fonts was messed up and all I see on through my goggles is a bunch of letter "v" covering the screen. I encountered this problem before, so I know it is an easy fix, but I need a computer. I did a quick test flight anyways, but it was a challenge to try and see past all the "v" on the OSD.
I was kind of sad when I realized that I could not use the same EMAX AVAN MINI 3 INCH PROPELLER 3X2.4X3 because it will not fit on the 1404 motors. The lower part of the Emax props entend lower and the larger diameter motors will not work. The only other props I have are RotorX Triblade RX 3044TX. I am going to try some of the HQ props when I get a chance to order it from Heli Nation. In my previous setup, this quad only weighed 85g and now it is 105g. I hope these larger motors are worth the extra weight.

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..

Interesting. I am running those Avans on same motors and frame. Did I missed something?
Maybe you are using a different prop or did you mount them upside-down? Take a look at the pics below. The first 2 pictures show how it should be mounted and it does not fit. The bottom of the props presses against the bell. But if you mount the props upside-down they props will fit. And that is why I am stuck with the RotorX props. I plan to order some HQ props to see how they perform.
lmao i know this is probs too late but i have the DYS 1404 which has the same problem but i was able to use the avans still...i just had to press it a bit down and the bottom of the prop would somewhat bend but that didnt affect the flight that much for me
Thanks for the tip. I will give it a try! I was able to get the props on by pressing it down as you suggested. Let me see how it flies. I hopes its better than the RotorX props im using now.
