Wall mounts for my RC cars

I designed (if you can call it that) and printed simple wall mounts for my RC cars this weekend.


This is how 5 of the prints turned out. My printer needs a lot of love to print. But when it prints it prints well. I had not given it enough love apparently. But when I took the time I got it back to friendly operation again.



And then this was the result. Simple wall mounts to hang the car by the tire. Turned out I actually only needed the middle screw hole.


The mounts in "action" with the cars dangling by the front tire. Haters gonna say it's bad for something in the suspension obviously.


The hanger is available on thingiverse for the ones that would want to print their own: http://bit.ly/2zQLxML



Final flight of the F-35

Last time I flew it I broke its nose. That was two years ago. After the nose was broken off, it might have been ugly, but it flew well.

And today was the day to fly it for the last time. Since I do not expect to fly this plane any more and it is ugly and taking up precious space, it was time to get rid of it. With a few final flights.

To spice things up I had 4S batteries prepared. ESC and motor is speced at 2-3S.

Away it went. My friend gave it a perfect toss and the power of 4S made it fly perfectly. It was fantastic. For about 10 seconds, then I misjudged the distance to a tree and the plane was converted to garbage.

Futaba replacement?

Well hello there dear old blog! It's been a while now. I haven't forgotten about you, I just haven't done much on the bench lately.

BUT. I did get myself a radio on the HobbyKing sale maybe a month back. Being a Futaba fanboy, I never expected that I would ever in my life buy a Flysky system. But now I have, I got myself a Turnigy Evolution. I've been looking at alternatives to the bulky Futaba, at least for the leasure flying I do at the office and now that it was on sale I ordered the Evolution at 35€, incluing a receiver.


60€ radio to the left, 600€ radio to the right


Ok. So, there's a small price difference between the 14SG and the Evolution. Don't get me wrong. The 14SG is a flawless radio, at least by the time it was launched. It has never ever glitched in the transmission and the telemetry was a great addition and quite unique in the price range before the Taranis arrived. I really love that radio.

But for flying quads, especially indoors I need two major features.

  • 6 channels
  • Voltage telemetry
And the Evolution has that. Yes, it has telemetry. And the receivers are dirty cheap. And the radio was dirt cheap. In fact, I think I can outfit most of my rotor crafts with receivers for the price of one single Futaba receiver. 

But how bad can it be? I'll get back on that if I have issues with it.

I will not forget to mention there are alternatives to the Evolution out there as well. One of them is the TBS Tango. It's a purpose built radio for quad racing and has some nice features in therms of programming. It is quite expensive, and comes without a transmitter. Which makes it ridicously expensive.

And coming up is a multi protocol radio called iRangeX iRX-IR8M. It looks like a knockoff of the TBS Tango and comes with multiple radio circuits built-in. I won't order one until there are some decent reviews online. My guess is that it will have a bit better gimbals than the Evolution and a poor feature set in the software. It's mostly the form factor, the basic telemetry and the multi protocol feature that will push this product.
