Radiomaster TX16S Review

Radiomaster TX16S Review

Radiomaster TX16S is probably one of the two most awaited for radios in 2020. The second one is the Jumper T18, but let’s not talk about it now. There will be time later to compare Radiomaster TX16S with Jumper T18. Let’s take a look at this hot radio and see what changed, why it looks like black T16, and is it worth the money they ask for it.

Diatone Hey Tina Whoop162

Diatone Hey Tina Whoop162 with FalcoX

I will be very frank with you: I do not like those tiny whoops. You know, 2″ and smaller propellers, plastic frame, a camera on top. You know, those almost cheapest FPV drones you can get. I’m saying that builds like BetaFPV 65X or Emax Tinyhawk are bad. I just do not like to fly them. Somehow flying indoor is not my thing and I do not have enough space in my home to do it. And taking those tiny things outside makes little sense. So, bottom line: not my thing.

Diatone Hey Tina Whoop162

When I was contacted to make a review of Diatone Tiny Whoop162 my first reaction was: meh… To be honest, I would turn the offer down and choose something more suited for my flying style, but then there was one thing that made me change my mind. The unit I was offered what flashed with FlightOne FalcoX and I wanted to give it a try for some time now. A few weeks later Tiny Whoop162 landed on my desk and this is my original impression of it. Bear in mind, I will ignore the FalcoX for now and concentrate only on the hardware itself. Read More

Bench power supply Yihua PS-3010DF

Some time ago I started to feel a need to have a bench power supply. Not laboratory-grade, but something that can deliver both some volts and amps. Of course with overcurrent protection. Aliexpress is full of such a power supply units and at the end, I’ve decided on Yihua PS-3010DF with 30V voltage and 10A max current.

Yihua PS-3010DF power supply

My initial thoughts are:

  • On the outside, it looks and feels pretty solid
  • You can power a drone on a workbench from it. Even with motors running!
  • Current limiting works and it can replace a smoke-stopper
  • Too bad you can not set max current before turning this thing on
  • It only shows current current, not the limit
  • USB is a nice touch
  • Teardown in a few weeks 🙂

Jumper T16 Review – better than FrSky?

Jumper T16 RC transmitter messed around in the RC hobby in the last few weeks. FrSky wants to ban it since according to them it’s a clone of FrSky X10 (bullshit by the way). The question is: is Jumper T16 a good radio transmitter worth the money and what’s more important, is it a real competition for FrSky Q X7, X9D Taranis and X10. The answer is quite simple: Jumper T16 is a good radio but everything else is a little complicated. Let’s do the review then!

iFlight ION Raaange/ION Drive 2506 1250KV Motors

220x motors are the workhorse on the RC hobby right now when it comes down to mini quads. Sometimes they are joined by 230x too. But 2205 and 2206 brushless outrunners have a serious problem that limits their use with propellers bigger than 5 inches. They might still be fine with 6-inch props, but on 7-inches problems begins. What 220x lack is torque! They are just too small to have enough copper wire and diameter to deliver enough torque to drive much heavier 7-inch propellers.

Let’s welcome something much more powerful: ION Drive / ION Raaange 2506 1250KV!

Mamba F405 and F40 40A 3-6S 4-in-1 ESC combo hands on

I have to honestly admit, up to the beginning of 2018 summer I was rather against 4-in-1 ESCs and flight controllers combos. The reason was quite simple: 4-in-1 were a rather new thing, had a tendency to burn without a reason and were quite expensive. Pretty much a normal state of a new technology. In comparison, FC + PDB + 4 separate ESC had more flexibility, were cheaper to replace when something puffed the magic smoke and seemed to be a reasonable choice when few extra grams of weight was not a problem. Lately, things started to change…
4-in-1 ESCs are no longer a new thing, manufacturers learned their lessons and prices went down! And that means you can get a decent quality flight controller and 4-in-1 ESC for less than $50. That's cheaper than 4 ESCs! C'mon, things ARE happening.

Today let's take a look at the example of a new age FC + 4-in-1 combos: Mamba F4 Power Tower.

  • 40A constant, 50A peak current
  • DSHOT support
  • uses QN3109 MOSFETs
  • current sensor

Pros and cons

Some pros and cons after taking a "static" look at Mamba F405 and F40 4in1 ESC

Pros:

  • pretty good quality PCB, I would even say surprisingly good for a price
  • FC comes with rubber grommets for vibration damping
  • side mounted DFU button instead of flat buttons or just pads on some lower quality boards
  • c'mon! $45!

Cons:

  • FC can be used only with 4in1 ESC, no separate soldering pads for ESCs
  • There are many versions of QN3109 MOSFETs, and depending which PDF you take a look at, 40A rating is either overrated or underrated… hmm…
  • location of pads for motors on the 4in1 is problematic. It collides with mounting standoffs. Careful soldering required!

Overall verdict? So far, positively surprised! Really, this thing goes to one of my mini quads immediately!
