This is an updated shopping list for the quads I’ve built for my 2018 flying season. It’s based on lessons learned during 2017, and I’ll be discussing the results and reasoning behind each part. Hopefully you’ll find this useful if you’re building a new quad or three and want to save some money.
The DJI Phantom 5 is the anticipated new iteration in the Phantom line, which fits somewhere in the “prosummer” tier of the DJI product spectrum. With so little information out, many websites are cranking up their hype machines to give fans some information.
It has been a while since I published my original Supplier Catalog post and things have changed. A lot. This post is an update, listing the parts I’m currently using to build my quads and the reasoning behind each one. I hope you find this useful.
On this post I’m going to share my latest procedure to configure and connect my FrSky D4R-II receivers in small spaces.
The Loc8tor is a device designed to help you track and find lost
items, provided that you had the foresight to attach a tracking tag to it,
which is kind of the point of this post. My experience is with the “Lite”
version, which relies entirely in RF beacon location tecnhnology to reunite
you with your RC model.
Properly mounting a video camera in your drone might not be as easy as
it seems. This is why I designed a very simple 3D-printed, adjustable
mount that will fit your Mobius, RunCam HD or Foxeer Legend 1 action
camera to your quad for a reliable, jello free experience.
Most people trying mini-quads get hooked pretty easily. Racing and
proximity flying gets your adrenaline pumping and encourages social
flying. Personally I’ve had a couple of interesting experiences with
I like using Afro ESCs for my DIY multirotor projects because they are inexpensive and for me have been working well. However as of late I’ve been motivated to research other options after a second model started showing what seem to be random sync issues.
Now, the issue with my 250 combined with my discouraging earlier experience with 690Kv motors was something I could not ignore. For me it’s clear now that SimonK’s firmware, while good for many – including myself with some of my mid-sized builds, one of which made a cameo at the video above – really has issues recovering sync for motors in the “slow pancake” and “very fast” spectrum.
Particularly in small frames you need to be very careful with space
and weight, as well as your cable management to keep things tidy and
well protected. A way to make cabling a bit simpler I’m experimenting
with consists in getting rid of some of the ESCs cables.
In this post I’ll share the details of the design of my custom H4
Quadcopter Frame. It’s a very sturdy yet light aluminum frame designed
to use 10″ propellers and 700Kv to 1000Kv motors. I fly 10x4.5
propellers with 800Kv motors on 2.65A 4S LiPo batteries with excellent
results. This is perhaps my favorite
DIY custom drone frame.
As I've said before in this post about NTM motors,
I use them in a few of my mid-size drones. I think that in the 400mm to
500mm range, these motors perform well enough to fly recreationally
and as long as you stay out of dust and land with the right side up,
they won’t disappoint.
PVC pipes used for plumbing are a good choice for building resilient
drone frames. I’ve used it in an H4 configuration and it works. In
terms of effort, cost and results, I would definitely recommend you
to give it a try, specially if you’re starting to build your own models.
There’s a certain pride in being able to turn common, every day
materials into something that is able to fly. At least that is the
impression I get when random people approaches and asks me whether I
made my quad myself. While my results are usually far from pretty,
there’s a lot to learn from building your own frames.
Vibration can affect your multirotor drone in many ways, some of them
non-obvious. In this post I’ll try to explain some of them along with
strategies to minimize its effects.
The Turnigy Multistar 4822 690Kv is part of a line of
pancake motors designed to drive large propellers at slower
speed. This is precisely what you need when building mid to large size
quadcopters such as my 650mm quad.
