Has anyone tried the $16.99 Professor Motor, B52 (50,000rpm) motor, in a flexi yet.?
 
Thanks

i have one, gonna put it in a GrF

[Tim Wood]

Just wondering how these two motors will compare to the Pheonix. B52 Professor motor and the Jk 11 motor just out. I guess Mike Swiss tried a JK 11  saying he ran .15 faster than the Speeding bullet Pheonix. Might have to regear my Pheonix rockets. Looking forward to your GrF test Mike. Thanks,

I'll try one more time.

 

The JK Hawk 11 is a drag motor.

 

I said I went a couple fast wing car laps with it.

 

Trying to regear your Phoenix is pointless.

[bbr]

the b52 is more inline with the RH and I expect it to be as such.

the phoenix and hawk 11 are designed to be drag motors from the stories I've heard.

 

by hook and crook the phoenix is able to run as a GrF power source, but for only a couple of race b4 it says "no mas"

at $20 a pop (as with any chinese motors, a fast one is a crap-shoot)... well you come to your own conclusions as to the cost/benefit ratio.

 

I've seen  a hawk 11 tested in a GrF and it was fast, faster than the phoenix, but also fast to burn up...

unless better material and better processing are employed... the hawk 11 will not run many laps in GrF.

but maybe someone will find the right setup combination to make it live...

Been running the B52-50  for a few months now, they are great, superb balance and a good set of ball bearings.

On a par with the PS 4002FK performance wise, but last a lot longer than an FK.

Interesting to see these motors being developed in ways that seem to be more like "can and end bell" types.  Hotter and hotter winds, ball bearings, balanced and tied arms...yikes!  Before you know it, people will want to open them up and make "adjustments"!

How many races are guys getting with these?

I mentioned this before, but I'm just trying to figure out the ball bearing thing, on a disposable motor, that has notoriously good bushings.

John,

 

Before you know it has long passed.

Opening them up is a right. Racing them after massaging is problematic.

Who's going to be selling the first FK motor with a Grp. 7 arm?

This seems strange to me also.  These motors are by design meant to be used "long enough" and then tossed, and the bushings on the (many) ones I've seen have never been worn, nor misaligned, providing for a smooth and solid way to hold the arms in the field.  I guess that, as long as the pricing doesn't start to get silly, people will be interested in the next "upgrade", so it's all good.  This all begs the question...are these (B52) motors being introduced in the hope that they might see acceptance from the sanctioning bodies?  Having what I think must be a large number made to satisfy whatever the minimum order must be seems like a no-win for the possibility of only selling "a few here and a few there".

Hey guys,

 

Just to keep this away from "why these, why now", I've no idea what Jose's intent are for these motors.  Jose offered these to the Professor to sell, along with some other B52 parts and tools.  All appear to be of high quality.  I've not tried the 50K yet, but I am going to make a cheater-womp with one for a laugh, along with a cheater using a Fang (don't ask!).  Quite a few 50Ks have been sold, and all appear to be happy with them.  We did hear about one, so far ONE, that had burned a pole, and it was replaced immediately.

 

I think we can all agree that a quality set of bearings will out-perform bushings for speed, but I've never had bronze bushings let me down.  Bearings however...

 

For what it's worth, and happy racing!

I think so Brad, but what quality these bearings are *might* matter.  I'm sure these are better, but the old Mabuchi "bearings" were a step-down from bushings.  Also, the sintered metal bushings in these motors aren't bronze, as they have some amount of iron in them.  That should make them even longer-wearing!

[bradblohm]

Hey John,

 

I should ask (and pay) for you to rip one apart, use the bearings, add the magnets from a Fang (don't ask!), add one of your "work of art" arms, build some kind of endell, and see what it's really capable of.  THAT would be a cheater to try!

Hi Brad,

    Well, the motor wouldn't be anything at all like the original, but it wouldn't be the first time.

Played with a b52 a bit in a retro F1 on king track.
Motor required a five seconds dip in simple green. Pulling .8 amps at six volt.
Pulls well off the top turn and thru the bank. Ran 4.0 - 4.1 in a F1 not suited for the bpr king, with Sam running laps. In a dialed-in F1 maybe  0.2 faster.
Have a few more b52s will see if they are just as good.

HI Mike - what gear ration were you running?

 

Thanks

Dave

10/27 is what we run out here in La La land

[iti20090]

Thanks, I am going to try 4:1 in our magnet scalex sidewinders as our traditional 40k motors seem best at 3.2:1 and I am worried about overloading the motor - clearly not an issue for non mag.

 

Cheers

Dave

I am running 10/36

[bbr]

gonna test the b52 in a retro can am this weekend at BPR

[iti20090]

Ran the B52 50K in an open magnet plastic car Saturday with 9:36 and was super impressed - until the spur loosened on the axle in the race..... ;-)

 

Magic smoothie quick motor, in to a Flexi next :-)

 

Cheers

What voltage are you running a king at with10/36?  R4 Hawk retro favored 9/28 on 13+vdc.

[tazman]

After reading this tread, what's the break-in procedure for this motor?
