20mm EDF unit


I've been sitting on this for a fair while now so better post about it so people know I am still having fun.
This is a 20mm EDF unit using a 0703 outrunner and clipped 4 blade quad prop. I'll start with a profile jet and get it airborne and go from there. My plan is to have have an indoor jet without too much speed and then go for an outdoor iteration.
This was kick-started by Micro_Builder who made the suggestion of using this particular outrunner for a small EDF unit.

Would probably help adding those huh?

15,000kV 0703 outrunner
AUW is 5.3g

Made to run on 1S or 2S

I'll have to make a jig to measure static thrust. When they run - I can feel there's plenty of get up and go so was very happy with the result.

Cool, there are also 06xx motors available which may also suit what you want to do.

Here's mine. I got this 20mm shroud from BIM years ago and never had a motor worthy of it. I'm using the new blade inductrix bl motor. Only because it was easier to get where i live. It's only rated for 1s but you know me, I have not flown anything but drones for the last few years
but have come back around. Hah! I know I'm limited by the 1s rating so I will probably use a larger fan if this does not produce much thrust, Or Nitrocharge it on 2s. Pun intended

Are you using the 0703 with bushings, or the version with bearings?

Bearings.

Woohooo! Hi Piet and Mike!

I bought a 3D Printer at long last as I feel the price is now low enough and the quality and strength is now good enough to get on board. This is going to make bringing ideas to life so much faster, cheaper and easier.

Here's the Printer at work and a few 20mm cases printed off. The black one is graphine filled PLA which adds 23% more strength to the model.

I look forward to reading the performance specs.....


You should try making a better 30mm edf units using the current crop of 1106 multirotor motors.....

Another guy brought up 30mm EDFs. Bare posted testing results for the fan, and I posted results with the 30mm fans in a twin scale airliner. From real world building and flying more 30-40mm EDFs than pretty much anyone here, many scale, the QX 7000kv is ideal. Not sure what "better" someone may be looking for, to put in a non existent model that nobody here seems to ever build, which also seems to be the theme for pretty much all fans discussed in this forum anymore.
