AXI source?
« on: September 13, 2011, 07:50:17 AM »
What is the best (cheapest) source for an AXI motor. I am looking to buy a AXI 2826/10.   :P

I don't know about the best, but Hobby Lobby seems to be AXI motor central in the USA.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

I found they all charge about the same but I have used Hobby-Lobby a couple of times.  Call to see if they are in stock.

After reading some of Christ’s posts, I have also been using the Scorpion SII 3026 -710 from Go Brushless - they have a SII 3026 -890 that would be an equivalent to the AXI 2826-10 (4 cell).  Very good performance from the Scorpion motor and great service from GoBrushless.com.  Parts are readily available - if you have read recent threads you might be interested in that too.

Are their different grades of AXI motors?  I am seeing pictures of AXI that look different.  See attached photos.

Just looked in the AXI catalog looks like the Gold Line is all there is.  I did notice a more "plain" looking motor (like your picture) in the accessory section.  This could be an older picture of a motor from a couple of years ago.

I too used the Scorpion 3026-890 in my SV 22 and have had 110 flights with no issues. I put over 260 flights on my SV 11 on Scorpions also. The Power 25 from E-Flite is also another very good and basically equivalent option.

John, Norm,

Along those lines, some years back, Hobby Lobby offered both AXI Gold and AXI Silver versions of some motors.  I bought two or three of the Silver versions of some motors that I was using for Old Timer R/C.  I couldn't tell any difference, but I admit that I wasn't pushing any of them as hard as the motors are pushed today.  (It could have been as much as 10 years back, don't rightly remember.)  I haven't seen any of the lesser grade Silvers offered by HL in several years.

My first AXI 2826/10 looked like the bottom pic and the next two looked like the top picture.  To me, they are the same motor.
The top picture is just the newest graphics.

I am now looking at the OS 3825-750.  Supposedly it can swing a 12x8E at around 11K on a 4S LiPo.  It is the same size as my Turnigy C3548 -900.  My Turnigy is swinging an 11x5.5 at around 10 to 11K (per a tack reading).  It runs cool.  I am guessing that the OS will pull harder. It will probably also pull more current.  However I am only using 55% of my 3000 ma pack as it is.  The down side is that the OS is a rear mount only.  I was thinking of flipping to a front mount but this is not possible wit the OS.  However the Turnigy I am replacing is a rear mount motor so the swap will be easy. I am looking for a better motor for my LA-5 for two reasons - More power and the ability to handle a spinner.  Just looking at the OS 3825 I believe it will do this very nicely.  Now for the point of this post - The cost at my LHS and or at Tower is $80.  This price is $20 to $40 less then comparable AXI etc motors.

The other interesting feature is that It is listed as a 3 ball bearing motor. A good thing I would suspect.  Looking at my Turnigy motor I can see the two ball bearings - one on each end of the shaft.  Where is the 3rd baring in a 3 bearing motor?  Is it simply a double ball bearing on the prop end of the OS?

Anyway at $80 bucks at my LHS this seems to be a no brainier.  n~

It's a bearing around the other end of the bell, to prevent the magnets from rubbing the armature when everything is getting deflected from gyroscopic forces.  Here's a picture of a Plettenburg with the 3rd bearing:

Ok that's impressive! If OS really does have 3 bearings in the OS 3825-750 it's a heck of a deal at $80.  The problem when you try and run a spinner on a Turnigy motor is the bell starts to vibrate as the motor comes up to speed. Their is a fair amount of flexing in a Turnigy because of it's small shaft and two small bearings.  I will post results when and if get the OS.
