Futaba T14GS

RC transmitters Posted on 2017-04-21 23:29

I have been using the Futaba T14GS for over a year and have been flying both FPV-racing and AP-drone with it. I actually don’t liked it so I was selling it. It is a nice radio but Futaba have made two major mistakes with it and a few minor ones.
Mistake 1: The menu-system is totally unlogical, at least for me. After over one year, I can still not tell how to adjust for ex. EPA, I need to klick a bit to find it. There are not just one menu but three different ones, totally not nessesary.
Misstake 2: The menu-buttons. The two on the sides feels very plastic and I accidentally klick them when flying. The “touch-thing” is sometimes not working for me before I wet my finger a bit. It is a clean design and “scrolling” is nice but for normal use it is not as good as a mechanical one.



DJI Mavic Pro

I bought a Mavic Pro to replace my GoPro-equipped Tarot 650(that is cutted down to 550).
I have been flying it for a while now and my impression is that the Mavic have two really strong sides, the portability and the imagequality(due to very good camera stabilization). However, it does not deserve the name “Pro” because it is not very good suited for professional use. Don’t get me wrong, it CAN be used by professionals but those professionals that will use it probably know its strong and weak sides and don’t think it is a “pro-drone”.
If you get a request to do flying inside or close to buildings you will probably need to say no because the Mavic have no user-selectable ATTI-mode and will just jump in to ATTI if the GPS-signal is to weak. So it is unpredictable in places with poor GPS-signals and that can be an safety-issue.
If you get a request to film from the sky at a certain day and time, you need to be quite sure that the weather will be good to say yes. The Mavic can handle wind but even a quite small headwind will give you problems with going a given speed in a given direction. Because the Mavic is always in GPS mode it first feels like it handle wind good, but it actually struggles quite much and that is to notice when going into the wind for a specific shot.

However, the Mavic is an really nice drone that gives very steady and clear video and good looking stills. The FieldOfView on the Mavic-camera is better suited for aerial photography than a GoPro or similar action camera that need to sensor-crop the already small sensor to get the same FOV. The fact that the camera on the Mavic is developed for AP makes it a clear winner over the GoPro overall in my opinion. I had Hero 3+, Hero 4 Black, Hero 4 Session and Hero 5 Session and was newer really happy with the picture-quality. The Mavic is delivering good enough quality to feel confident. But for me, 1080p/60fps looks really bad with the Mavic so if there is needed slomotion, I think that the GoPro cameras are better.



Better tires!

RC Crawler Posted on 2017-03-27 07:59

I bought better tires for the New age crawler. HPI #67772They are a bit bigger and a lot softer than the original tires.

The grip was much better and the clearance under the axles become a bit bigger so I think that change tires is the first upgrade that should be done.



SniffSwe X – Quadcopter frame

Race quadcopter Posted on 2017-03-05 15:00

This frame is today a
bit different but not uniqe because I have seen the concept before
and I am sure that there will come a lot more race-frames that build
on the same concept. This frame is a X 210mm with 4mm top-plate.

Compared to a more
traditional frame:

More protected motors
and ESCs at high speed
Less turbulens around
the arms – There is no high pressure-waves from the propeller-blades
that is banging on the arms, the arms are still affected by the
propeller blades but it seems to affect less and give a more steady
quad
The FPV-camera is well
protected between the arms
The propellers are
slightly lower compared to the top-plate – Keeps the propellers out
of view easier
Battery strap can be
used both at the top and bottom – You can choose if you want
battery on top or under or if you want to fit an action-camera
Weight 91g including
the battery protector plate (86g without)
4 mm top plate

At first look, it looks like the quad is upside down but for me this is now the correct way 🙂

The top-plate is protecting the motors at higher speeds – On traditional frames with motors on top of the bottom-plate it will be the opposite and the motors will be more exposed at higher speeds

FPV-camera is well protected by the thick top-plate

This is the most reliable way I found to mount the VTX-antenna, it is placed right between the arms and supported by a stainless steel rod-bracket

There is also a hole in the top-plate that give the option to use a pig-tail

Action camera can be straped on top

For flying in the winter I have a 3D-printed body that cover the electronics

I have this frame for sale if someone is interested: WebShop
