As part of my long range series I've decided on an objective for the buildand sourced the parts primarily from Amain Hobbies who are based in the US, and this article can be found here. These parts have been delivered and I have now completed the build process which is documented below.
If you are attempting a long range build then you are probably not new to quadcopter building. Regardless, please see below for some things that I light to have before I start a build
The Diatone GT-M7 is a lovely frame in my opinion with some nice features. It went together easily even without instructions although I did need a plastic M3 washer between the head of the screw and the frame that holds the front of the canopy to the frame. Picture below does the talking.
Motor and camera install
Nothing much to see here other than the fact that I love the loom tape that is available from banggood. It is very light and looks much tidier than electrical tape. Brother Hobby Returner R6 2306 1660kv Motors held on with all four screws each whereas I usually only use 2 on other builds
This is where it gets a little tricky due to the relatively tight space to work in. I did a lot of test fitting with various hardware and location of boards but a common element for all builds now is that I use proper long steel or stainless steel screws for the stack. This makes for much more positive mounting than those crappy nylon standoffs and allows for more variation in spacing. As it was the ESC ends up on the bottom, then the flight controller, then the vtx/dvr. I tried to sandwich the crossfire nano receiver between FC and VTX but it was a little too tight. GPS will go on top of the receiver until I get a go pro at which time I'll relocate to an arm. I'm pleased with the immortal-t antenna location which looks good and should give me enough range to meet my objective. I really like the VTX antenna mount which is clean and gives a sturdy base to get a long antenna on. A also like the pivoting cage which makes building and servicing a little easier given the tight space. All pictures below to cover off anything in more detail that warrants discussion
What would I do differently?
Anytime you get to the end of the build to see what you'd do differently and I'll quickly note some of the things that went through my head.
These VTXs still allow you to stack mount but offer more peripheral space.
That is it for the build, I've since powered on and setup software to confirm all is working and I'll cover this in the next article since moving to crossfire and setting up GPS took a little more work than I am used to. Maiden to follow after that, hopefully with DVR.
