This weekend, thanks to Foxeer, I had an opportunity to test flight new Dalprop freestyle props: Nepal N1. Although the name is a puzzle for me, I’m pretty sure Dalprop Nepal N1 might make some stirr!
Do you know this old saying “If you want something done right, do it yourself”? I do and sometimes I just live according to it. Not always, I’m not crazy, but at least from time to time!
I fly 7-inch FPV drones a lot. To be honest, they are my favorite flying devices. There are a few good 7-inch frames, like TBS Source One for example. There is a difference between good and great tho. I do think that Source One is a good frame, there are a lot of things on it that do not make me very happy tho! The list might not be very long, but it is relevant:
- props in the view
- limited space to install split-like hybrid cameras
- no very convinient place to install VTX
- it’s not that big inside as one might imagine…
I love 7-inch FPV drones and during the last year, they were my most used FPV gear. For freestyle, cinematic, cruising and long-range. I currently own 3 7-inch FPV drones and 4th one in the assembly process.
I think of myself as a 7-inch expert. I’ve wasted enough money and equipment to know what works and what does not work well with 7-inch propellers.
If you are thinking about building your own 7-inch FPV drone, here are some tips that might save you a lot of time and a lot of money on wrongly chosen equipment. Read More
Although I moved to 7-inch FPV drones, from time to time I would like to have something small. Not a whoop, just something small. Like 2-inch propellers. Banggood has a nice promo, so I purchased a Diatone Rabbit R249 NX and here is what I think about it. “Amazing”? Niah. Closer to “fine” than “good”. For all the details watch the review.
Here it is Penta Engine Nitro Incredible Ship – P.E.N.I.S. Or shorter: Willie. OK, let’s be serious for a moment. It is a pentacopter. A normal 5-inch FPV drone based on Martian II frame with the 5th motor attached in the back. When I flip a switch, the 5th motor starts and it flies almost like an airplane. It’s a VTOL. The idea is not mine and a few years ago there was something called Foxtech Screamer 250.
Once a year I have this crazy idea: build an FPV drone capable of flying in the night! Since it’s not that hard and you only need some special hardware, it works. Slam a starlight camera like RunCam Night Eagle on a 7-inch drone and you are done! And some LEDs for visibility. And 3W headlights. Even this will be enough for super sensitive starlight RunCam Night Eagle camera.
This year my friends and I stared a local FPV drone racing series. Nothing serious, just a couple of guys meeting once in a while and measuring times over the track. 100% amateur thing. After the second race, I’ve realized that I do not have a drone designed for racing: more than 400g without a battery! That is just too heavy for any kind of competitive racing. The solution was simple: I need a good racing machine. Much, much lighter than the current one.
As a result, Mach 1 was born
I have a theory that 7-inch FPV quadcopters fly “below expectations” due to frame resonance, I did not expect, so many pilots agree with it. We had nice talks in comments, I’ve learned a lot about stiffness and moment of inertia (that you Pierre-Louis). Many of you shared some of their tricks and ideas on how to solve that. Let’s start testing some ideas how to fix that!
I will keep it short: drones are not designed for a long flight. Sure, you can put bigger props, bigger batteries and make it lighter, but comparing to even simplest airplanes, there is nothing to compare.
The conclusion is: try airplanes. They are cheap, simple, easy to fly with modern flight controllers and are much more efficient than drones!
Do you know, that with proper equipment you can fly your drone at night? In darkness? Without any lights? You only need a special camera that can see in the dark. I’m using RunCam Night Eagle that unfortunately is now discontinued and only Night Eagle 2 is available.
Night flying itself? Pretty cool!
