Hi. . .

I built this drone for mid-range and freestyle.

I've tried a lot of props with different voltage and for me the best prop for this setup are the gemfan flash 6042. They can be used from 4S to 6S. But for 4S Mid-range cruising I prefer the emax longrange.
If you like my build pls like it and if not leave a comment and let me know what you would do better.

Hi, i'm building the same frame with t motor f4 hd stack (same esc) paired with f80 2500kv for 4s use. Do you have any advice for the propellers? I like precise and fast fly. Thanks

Enyo   May 05, 2020 

Try the t-motor T6143

Hi, what is the best setup combination for mid/long range (props & Lipo) and possible cruise flight time.. Thanks

Enyo   Dec 09, 2019 

Emax Avan longrange and 6S 2200

Pimpmykwad   Jan 28, 2019  

very nice build!!!! no njello with bipale??

Do you have a link to the GPS holder, please?

Enyo   Dec 20, 2018 

My friend is on holiday . He printed it for me. He will upload it when he is back.

haplm   Dec 21, 2018 

Thanks! One more question - I'm also going to use F55, any special reason for the orientation you chose? I'm thinking about rotating it 90ยบ, so the power pads are to the right (or left), similar to what what Neill from CMW shows in his build video.

Enyo   Dec 22, 2018 

Just becauce if the conector to the flight controller. My wires were to short as built the quad .   Nov 21, 2018  

love it. If i could build ANY quad i wanted i could use yours as a template. so very nice!

u tried 7" arms and props? just curious

Enyo   Nov 22, 2018 

I think 7" props wouldn't fit. There is not enough space between rear prop and lipo.

Hi ! Nice build! I'm deciding for a mid range build...I see you have F80 motors, how are they handling the power from the battery? which kind of battery do you use and how much is the total AUW weight? Thanks!

Enyo   Nov 22, 2018 

Hi simon ,

The total weight of the kwad is 524g without lipo and gopro.

4S Amax 120c 1800mah ~90A with emax longrange 6038

5S Tattu R-Line 1550mah ~120A with gemfan 6042 Bi-Blade

6S Tattu 70c 1300 ~160A with gemfan 6042 Bi-Blade

Its called diversity

Jodie Froster   Nov 11, 2018  

Good LAWD! You did ALL the things, this is the dope-ist 6" i've ever seen.

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..
