Hi guys thought this maybe of use to those of you thats interested... alot of people have had trouble with there 600n's fan and revlock sensor mounting.
(sorry for the poop pics my camera needs charging so used my phone)
Firstly the fan, everyone knows how flexible it is and goes out of shape when tightened onto the hub and also throws magnets!
Heres what i did basically made a big 1.5 mm thick washer on the lathe, it has the same I.D as the hub, its O.D is the same as the I.D of the vanes on the fan. i then drilled the four holes at 90 degrees to each other two at M4 and two at M3.
Then i bolted it on going through the fan and into the hub(see pic), when i did this i poured boiling water on the fan to soften it up(you could warm it with a heat gun gently!) then once tighten it pulled it straight and firmed it up...clever eh
(use thread lock and you need slightly longer bolts to compensate for the thickness of the washer!)
another thing i did to the fan was to drill the recess for the magnet at 90 degrees to the orginal directly above a vane and set it with 5 min epoxy flush to the surface... its never thrown a magnet yet!
after this i balanced it on a high point balancer.
I use a revlock so here's how i made the bracket.
quite simple this one! use a synergy bracket and modify a follows,(see pic)
fix the sensor on the silver side with 2mm hanging over the end(tack with cyno then heatshrink) on the opposite side you need cyno a 2mm thick material of your choice(i used balsa) then sand it at 30 degree angle(it helps it align with the magnet in the fan) coat it with cyno to fuel proof and redrill the holes,on the same side as the sensor i cut down a JR super servo horn filled the holes with glue, keyed the sufaces glued it to the bracket and shaped it , turned it over and drilled through again, this is to self tap into instead of using nuts and bolts...much easier(i used raptor servo mounting screws and ground a couple of mm off the length also made a one peice washer for both screws)
It maybe a good idea to drill a small hole in the frame either side of the sensor and use a small cable tie as it stops the sensor sliding down into the fan
think thats it hope it helps you guys
