My goal was to build a premium 3" Quad and here it is!
I's flying very very well with BF 4.1 default PID's and has a enough power for the way I'm currently flying. Maybe I will switch to 4s someday, but for now I'm more than happy. My plan is to integrate a RunCam Split mini which is already waiting on the bench. But at first I want to see how it performs, the Spit is the next step.
I want to report some findings which have been disappointing so far ...
Finally ... I have not expected such things on a parts from a well known brand like Lumenier!!
I will post a update here once I have installed the RunCam Split. Maybe I will also add a YouTube link to some FPV footage then.

Update ..
1) Got sick of my Runcam Split mini ... keep going with the Swift as it has the better picture, consumes less power and the split PCB is hard to install. So no HD footage for now :-(
2) I already have ripped two micro axii antennas (the second one after 3 minutes using it after I have replaced the first one) in both cases the head of of the antenna has been tangled during a crash and then destroyed because of the resulting high forces. The first one in high gras the second one in a tree. Now I'm using the linear antenna which came with the vtx and have to wait for further spares.
3) Although I have a lot 3S 850 Batteries I will switch to 4S .. I have tested 4S 650 and 850:
3S 850: 80g, Approx 4:30 flight time
4S 650: 70g, Not more then 3:30 flight time
4S 850: 110g, Approx 5:30 flight time
The 4S 850 gave me imho better freestyle performance as it has less voltage drop compared to the 3S 650. I also like that the quad has more momentum in those swings over trees. Beside of that I think it fly's more stable with the extra wight. Anyway .. 3S is ok to get used to the quad, 4S is WAY more fun .. So I will switch over to 4S 850 R-Line batteries.
My conclusion .. go with 4S and use a throttle curve the power scares you to much, don't use the micro axii antennas as they are not very robust and HD footage is not everything.
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..

So finally this one is retired because of a broken arm and the lack of avaialble spares for a reasonable price in europe. I was flying so well that it has become my reference for the following builds. It's successor is a micro reverb which is resuing the most parts used here.
