ZMR250 Multirotor Frame

ZMR250 Frame

My first 250 size quadcopter frame was a ZMR250 which I have been told is a clone of a Blackout 250. The Blackout costs $150 from GetFPV while the ZMR is available for as low as $20 from various sources. I got my first one from Banggood in May 2015, it required some drilling to get the 2204 motors to fit the arms and the SMA VTx to fit through the top plate, but I was pretty happy with it overall.

My initial build included:

  • Banggood ZMR250 Carbon Fiber Frame
  • SimonK 20Amp ESCs
  • SunnySky 2204/2300kv Motors (I think they were knock-offs)
  • 700tvl Sony Board Camera
  • ImmersionRC 600mw VTx and Spironet Antennas
  • Naze32 Flight Controller
  • Home-made Power Distribution Board

I chose black and orange as a color scheme using orange shrink-wrap and propellers. After making a lot of mistakes and burning myself with the soldering iron a dozen or more times I decided to name the plane “Orange Pain”.

Since May I have rebuilt the machine a number of times due to burnt out or broken parts. I have gone through a Naze32, two 600mw VTx, a very expensive board camera, a top plate, three motors, three SN20a ESCs, and a ton of props. I bought an FPVModel ZMR250 and built it as a second plane but have since parted it out.

The current iteration of Orange Pain includes:

  • A mixture of Carbon Fiber parts from the original Banggood frame and a FPVModel ZMR250 V2 frame
  • RotorGeek RG20A ESCs
  • SunnySky 2204/2300kv (I think these are real)
  • Fatshark 250mw VTx
  • 600tvl Sony Board Camera PZ4020
  • Naze32 Flight Controller
  • DYS Power Distribution Board

I think this is a great setup for an intermediate racer or daily basher. I am currently struggling to get the tune on it right and am ready to pay someone else to tune it for me.

After rebuilding the machine a number of times I have learned a few things.
The expensive FPV cameras are not worth it, stick with the $30 Sony PZ4020 or PZ4020M with or without a case.
600mw Video Transmitters are not needed and the extra heat can greatly shorten the life of the unit. A 200mw or even 25mw transmitter may last a long longer and provide a signal that is comparable to the higher-powered transmitters at racing and public park distances.
If you short out a flight controller it is probably ruined. It is good to have an extra on hand.
Spend the extra money on 2 sets of drivers, keep one set in a toolbox at home and carry the other set with you.

I really enjoy my ZMR and recommend them for people getting started who want to build their own. The FPVModel ZMR250 V2 is made of a much higher quality carbon fiber than the Banggood frame, but the cheaper frame is not a bad buy.

ImmersionRC Vortex Pro-Tunes

Vortex 285 – FPV Race Quad

Vortex 285 – FPV Race Quad


The Vortex comes with 10 “Pro-Tunes” that were developed by sponsored pilots before its release. I did a bunch of Googling after buying the Vortex to try and find more details about these varoius tunes and found nothing more than a short video from UmmaGawd about the Vortex.

So here are all the tunes as of October 2015. I hope they add some new ones soon that are specific to newer motor and prop combinations, especially DAL props.

In the next couple of weeks I hope to experiment with each of these tunes and see how each performs with the props described and with various DAL props.

Immersion RC Vortex First Flights

Vortex 285 – FPV Race Quad

Vortex 285 – FPV Race Quad


I have seen a handful of people flying Vortexes around the Atlanta area and after rebuilding my ZMRs like 5 times I decided to give the Immersion Vortex a try.

I bought it from Atlanta Hobby along with both the Carbon Fiber Crash Kit and the Plastic Crash Kit. I also got a cable to allow me to easily connect a Spektrum Satellite receiver without having to make a cable of my own.

I got it home, took it out of the box, connected it to a computer and installed all the updated and such, then was ready to fly. It took me a couple of weeks to have the time and place to fly it, it rained 3 weekends in a row.

Once I finally got to fly the experience was very good. I started out with the Gemfan 5030 props that came with it, Turnigy Nano-tech 3S 1300mah batteries, with a RunCam HD, and used BewweB’s Pro-tune number 2. It flew really well and was a lot of fun. Not what I would call fast or agile, but still fun.

Next up I put a Glacier 4S 1300mah battery on it with DAL 5030 props, it was much faster and a bit more agile. Then I swapped the props out for DAL 5045 Bull-Nose props, but they were too aggressive and drew more amps than I was willing to risk.

Right now I feel like the Vortex’s largest issue is the proprietary 12 amp ESCs. 12 amps is not enough to run 6 inch props on 4S batteries without burning them up very quickly, and right now you cannot get replacement ESCs and without doing something extreme you cannot use larger ESCs.

After 7 flights with a mix of 3S and 4S batteries the ground cable to the FPV camera broke at the connector. I fixed it by cutting up a cable from a RunCam FPV camera and soldering together with the Vortex FPV cable. I also popped the cap off the video transmitter’s antenna, found it and popped it back on, but I plan on gluing it on before my next flight.

Overall I think the Vortex is a decent quad, the trends have changed a lot since its creation and so it has fallen out of favor in comparison to smaller multirotors like the Shendrone’s Tweaker and Krieger, but that does not mean that it is not a good quad. I think it is suitable for fun-flying and even racing at a beginner to intermediate level.

Sorry about the lack of video, the RunCam HD was not at enough of an angle so about all you could see during my flights was the ground. A quick Google search will lead you to many videos of pilots much better than me flying the Vortex.
