Started a section on Neu motors - a victim of their own success the wait for repair at the San Diego factory is now over 4 weeks - those equiped with suitable tools and know how may choose to have a go at fixing the motors themselves especially if you live on the other side of the planet from Neutronics !

Basically replacement of bearings or a popped end cap is pretty straightforward - the problems comes if the bearings collapse which then allows the stator to graunch into the rotor wirings and destroy the brittle (and $$$) Neodymium stator magnets- so pay good heed to the advice on the Neu website:

Note for heli motors! Be sure that you check the motor bearings for noise every few flights. Excessive side loads on the front shaft can damage the bearings which can lead to bearing failure. Be sure to double check gear mesh and make sure it is not too tight! If there is noticeable play in the bearings they are making noise then it is time to have the motor checked! Damage of this type may not be covered as a warranty! Use your ears and avoid problems. This is most important for the 3D type fliers!

John.... I gotta say man this is some good work on the NEU motor.....

Thanks man YOU ROCK!

hi does any one know where i can get Johns Video from for the Build of T-rex600 please. They were on this site few days ago, but seem they have movied. Any help will be most appricated.

All my videos are on this thread - have only done bits of 600 build like crash repauir and main grips upgrade - Bob has done the real deal

[Mercuriell]

Here's the link. kindly provided by Charley, for the Rotorworkz 600 Nitro frame assembly - I received these in the post today and though I'd do a one off video on their assembly to point out the enhancements over the stock frames

[Mercuriell]

Posted videos of the Rotorworkz T600 Nitro replacement frames - not a whole lot different from the Align variety but precisely cut (everything lines up !!) and a few nice touches like blind nuts for servo mounting, gyro tape slot, reinforcing strut beneath engine bay, break-away canopy mounts and included servo plate for a mixer servo. Really worth considering if you need new frames or want to do an E to N conversion.

[Finless]

Never mind......

John the build vid cuts off at the end right in the middle of your sentance talking about the main shaft going in and out smoothly?

Should be fixed - had to rush out to LHS for a couple of servos save ripping the guts out the old E - rather than swapping an E for an N looks like I'm heading for FOUR T600s - any advice on divorcing old helis ? Anyway had to use up that Kasama Head on something - incidentally didn't realise Kasama built in Bangkok so may have to get the wife to ring up and talk Thai speke for a factory visit next time we're over there

[Finless]

That sound slike fun! Kasama is a good friendly guy I hear too!

Enjoy the head. Believe it or not I have still not flown mine yet! Next Saturday for SURE.....

Did a quick calculation on the Helidirect website to find the cost of extra parts needed to change E to N and that comes out with G10 frames to US$323 - so not a huge saving for re-using your rotor head and tail assembly as the HD price on the GF kit is $399 - but it would provide a customised kit with a few of the nice touches of the RW frames - maybe someone will come up with a deal for the whole kit and caboodle !!

Added in video on Hitec 6975 servo gear overhaul - bit different inside from the HS 56 in Bob's servorepair101 and slightly different approach !

[Finless]

John!!!! GREAT VIDEO MAN....

Thank you!

I am going to have to call you my Finless "down under" twin or something

Super cool video for sure!!!!!

New video on the Neu 1910/1Y/H - brief intro on a motor with failing bearing then my steps taken to disassemble the motor and replace the bearings. On the Neu 1910/1Y/H these were flanged bearings F625ZZ - on the 1910/1Y/F they are smaller diameter (?? SMR115ZZ - 11x5x4).

If anyone has information on bearing sizes and types for other Neu motors it would be good to publish them here for reference.

[th3tick]

You said the 1515 has the same bearings? Is that the 1515/2.5D/F/H?

Mine have always had that whine you show at the beginning of the video...

EXCELLENT video! Thanks for the effort.

Those blue towels sure look familiar

[Mercuriell]

Hi John - my 1515/2.5D/F has SMR115 bearings (11x5x4) - these looked to be the same as on my 1910/1Y/F but without disassembling it I can't say for sure (it's a new motor so I hope not to do that just yet!) - they are pretty small bearings and I heard rumour that Neutronics were upsizing them on some of their motors.

The bearing sound is subtle and maybe doesn't come across so well on the video but is a harsh ringing sound rather than the whine of the motor fan and seems more prominent at certain revs - took me a couple of flights before I cottoned onto what it was. I think that the abrasions in the CF of the stator were probably caused by increased inner race radial play of the bottom (pinion side) bearing.

Blue towels certainly handy - great for cleaning up nitros or windscreens too ! - amazing (disgusting) they're single use!

[tomheli]

bob can i get your thoughts on the g force gft6180 pro cage for 600n , thanks

[Finless]

Never used that cage so sorry cant tell you.... I am curious though why the Align cage is not good enough? Mine seems just fine to me.

Bob

[Mercuriell]

By special request put up video on bearing change on the OS Hyper - quite a lot of corrosion made removing the sleeve and conrod a PIA - anyway hope you enjoy
