Upcoming Castle Outrunner Motors

OMG! Dude! PM me with stuff like this! LOL

Did you make it a reality? Got pics of the prototype? If not, I have some ideas!

[MetalMan]

Never did make anything out of it because I never came up with a practical application. Even though I really enjoy working with outrunners (you know how much I've done with them), I prefer using inrunners due to their greater performance in a smaller package.

However, my XLB is still looking for a suitable motor and it has a center diff... Thinking something like a 4025-4035 might be suitable. The diameter is my only concern, because the motor mount was designed for a 45mm maximum diameter motor with 30mm bolt spacing and M4 screws.

EDIT:
Patrick, a suggestion for you: send one of your 40mm diameter outrunners my way for testing purposes in a car. Something with a stator length of 25mm-35mm and a kv of just under 500 and a shaft diameter of 5-6mm. Then we can see what those motors are really capable of .

They won't fit Castle motors.

I never claimed they would fit Castle outrunners, I was just responding to Metallovers postulation.

Ok, take a look at this.



What do you see?

Remake the motor shaft from a transmission input shaft. Then the slipper will bolt right on like normal. Both shafts are 5mm.

I can see alot more gearing choices this way. OR wouldn't it be different if the slipper was on the motor?

Hmmmm..........the possibilities.

[Metallover]

Can you link us to a suitable shaft?, or have you not done this yet..

[What's_nitro?]

Nice..............

How are the tolerances on the input shaft (diameter)? I was thinking more along the lines of buying a die and modifying the original motor shaft, but your idea obviously requires a lot less work

The Tolerances are good!

The bearings of the motor AND the bearing used in the transmissions have the same ID. Very nice fit. I just tried the input shaft into a 2826 that I have here.

The 2826/8 won't work with this type of gearing, but a lower kv motor would. I'll have to plug some ratios/kv's in and see what pops out.

[What's_nitro?]

Hmmm maybe CC will take interest in this idea...

[MetalMan]

For my XLB I came up with:
-6s Lipo
-standard 43/13 front and rear diff ratio
-44t Kyosho spur gear for center diff
-36t Revo spur gear

A kv somewhere in the upper 400s to 500 would be suitable for this application. If CC's outrunners are like other typical outrunners then the kv choices will be similar. The motor I am interested in (about 4025-4035 size) will be offered with a kv in the range of 400-700.

I see a 450kv in the 34mm CC motor line! This line of CC motors is different. I'm sure intentionally.

The kv is determined by the wind. A huge outrunner can be rewound to a relatively high kv, but your system couldn't handle the startup amperage. On the other hand, a small outrunner can be wound to a low kv, but have torque out the wazoo.

Patrick was saying they ran a 30mm motor up to 1000 watts burst. Probably in an airplane no doubt. LOL

I wonder what the power handling ability of the 34mm line is going to be?

What is the stator size on the 34mm line of motors? 28mm x 34mm ?

Need more input!

Patrick is indeed going to have to give us more specs... WE NEED THEM. And some test motors would be nice
Granted if we did test motors for Patrick, it would be more of durability testing than anything else.

[Metallover]

I'd test a cc outrunner...

"WE", like you and me? Ummm.........you mean like Beta testers or something?

Hey! That would be GREAT. As a matter of fact, I think I read something about that somewhere.

Where is Patrick when you need him?
But to be fair, Metallover would need one too
