This is my 3rd 4" build and 2nd FlexRC 4". Had an Intrepid V1 that i am swaping these components over from in to this new frame. Unfortunately the HGLRC FC i had in this build turned out to be not connecting to the PC for some reason(Have another on its way from Racedayquads) I will also be using this quad a test platform for the Hobbymate Frsky D16 RX that I recently received to review.

The simple wide open design of this frame allow for alot of freedom and ease of building. However, due to the open nature, a clean build/stack is important to avoid loose wires or things that can get snagged easily.

The piggy back style VTX is made to fit on a Micro Swfit, but I was able to put a small cut out in the the case of the Swift Mini I was able to adapt the VTX to the cased style camera. A liberal amount of hot glue holds the VTX antenna in place which will be changed over to E6000 when I get around to it.

Other than that there is not a ton to be said about this build. I didn't need to do any sanding or special fitment for the frame and everthing was very smooth in going together! Will add videos and pictures soon!

( I will also be using Jumper T12 ( which I am currently working on a review of on this site as well.

Woah! Fascinating, thanks for telling me, I never would have tried that. Have you used it on ufl connectors? That and capacitors are about to get some e6000 if you are telling me that you have. Sometimes my vtx heats up and flows the hot glue around where I don't want it.

Yup! it takes a bit to dry but i use it on all my UFL connectors now and usually run a thin layer across the wire connections on the VTX and such as well. You can see it in the pictures a bit more in the 6" Ruxus build i just finished as well.

Just a few years ago we started racing drones around a track and doing flips over trees, but professional cinematic FPV is a more recent development. DJI has always owned the drone photography market, but smaller acrobatic drones are starting to enter the market. They have the advantage..

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..
