I tried to avoid posting this build because I didn't wan't to know how much I spent on it, but I now feel obligated after all the questions people have asked about it. I'm still going to avoid looking at the total price and when I inevitably glance at it, I will squint my eyes harder than someone who got sprayed directly in the face with mace... Now on to good stuff.
The build started as a desire to see how fast a 6" quad could be when optimized(Also becuase I freaking love 6 inch quads). I was tired of hearing the "experts" claim that 5 inchers were the only size that could go fast (above 110-120mph) and that anything even slightly larger would require a copious amount of power that current battery technology could not provide. I knew 6" had potential to reach high speeds, but a suitable high pitch propeller didn't exist at the time. That changed when APC released a reverse rotation version of their 6x6 airplane propeller last year.
I originally planned to use my own base frame design, but I discovered the ruxus v2 right before I was about to get the carbon cut. The ruxus was almost identical to my idea with the most important similarity being the very thin arms. I then chose the FPVAF 2507 2200kv (made by hawksky) due to the fact that the hawsky 2207 was very close to the cobra cp2207 based on thrust data from miniquadtestbench. That means a 2507 using the same construction would be really powerful!
The first tests on 3s yielded speeds over 90mph. My theory about a high pitch 6" prop was correct. The apc 6x6 was literally 25-30mph faster than any other 6inch prop(and more efficient at high speed too). 5s runs consistently hit 150mph, but the first 6s tests were a little disapointing with most being under 160mph. I could have stopped at that point. Those speeds are right up there with the fastest conventional 5" quads (not including Ryan's fast crazy machines).

This is the fun part of the hobby, pushing the limits. Showing people they dont have all the answers.
I think unpolished builds that push the limits bring more to the table than showroom quads. it shows the ingenuity, the grit and determination that you put into it.
I like it.
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..

I admire this: "my "workshop" Is also my bedroom floor". Adverse conditions bring out creativity and resourcefulness; it creates an in depth connection to the problem at hand that $ and computers cannot replicate. Among the small 5' x 6' corner workshop in my apartment you'll find a coping saw, files, sandpaper, electical tape, and Easter eggs - not exactly high tech.
