Next, cover the Mylar.

Looks great! What happened to the contrarotating system?

Hi George .
I thought up how to make a very simple contrarotating system.
But I have to do the test.

Hi this can work , I work with engines and alternators for industrial ,shipping and offshore and in some cases we have problems with bearingswear because off that they has some electrical current through them , but in this case I recon that the current will be smal but it can be an issue ,but the running time will be wery low compare to the machince that I spoke off in the beginning.I have seen similar construction but with sliprings.

Spent two hours time and the motor weight 12.7 grams is ready.
With ACC 120 Ma, flight over 6 minutes.

Thats a pretty impressive improvement. Since I have both a lathe and mill, I usually lighten my motors too but I've never taken it as far as you have.

Interesting but why go with this motor when your friend took a Hacker A10 15S to under 10 grams?

From the flight time I assume you have flown the Relax4? Did it meet your expectations? Any video?

We can try the XC2803/60 F3PN


14.2g in origin setup with three-point radial motor mount.

Hi George.
Relax-4 requires adjustment, soon I'll make a video.
Hacker is a bad motor result after conversion.
Hi Nicolas.
Your motor after alterations may weigh less than 12 grams.
