I´ll try that, cos i had to replace the motor twice. From that i have enogth Holdingplates to modifi. I must only buy an Brushless motor to start the work ;)
If you wanna see some of my things i milled by hand without CNC, send me an IM, so i can send you an link ^^

Original motor output is 100W. It can be easily replaced, if it gets broken. I like not modifying the machine too much. But, hey! Your idea is clever. I'm a aeromodelist builder as well, and do have spare brushless around. But I don't feel like following your idea right now, I'm happy with the machine as is. BUT once you try brushless on MF70, post videos! Sounds interesting.

That´s why i am planing to replace the original motor with an Brushless one from an modellplane. This motor has an output of 240W, and it can run with 1000 to 20.000 RpM, with lower noiselevel. After that, i start st make my machine CNC.

It's an idea. Buil-in fan is effective at high speeds, but MF70 spindle motor suffers at low speeds.

I add to my MF 70 another cooling fan from an old computer

MF70 is driven by Cobra board. Look at my site.

can you give Me pls your microstep driver information thank you ideegeniali

It was a ready-made example found somewhere on the net.
your video real time or fast video:) my mind is very speed cut:)

All my videos are real-time. You may confirm by spectrum analysis of sounds (and you know top-speed of proxxon mf70 spindle). Or you may watch debribs falling down at G=9,81 m/s^2, normal gravity. At fast-videos, you see debris falling down speeded up, and hear an unusual high-frequency out of the spindle. Enjoy! :-) U-Mill is only 1mm diameter, doesn't have to machine lots of debris, material is wood, so you may use higher speeds than when working on aluminium with 2 or 3 mm U-mills.
