Default OS To Make Brushless "E" Motors!!

Hey Guys;
This maybe old news, but, I receive a email from OS Engine today, telling me about their new line.
Below is a link to OS website with more info about their new line.

Oooooh. I might actually get an electric now. At least I'd have a motor I could trust...any idea when they'll come up with speed controllers to match?

Motor you can trust?

Have you had them fail for reasons other than overloading the motor?


I've several dozen electrics many with cheap chinese motors and I have yet to see one fail EXCEPT when I overload the motor.
And the latter is always purely my fault for not getting the combination right or double checking with a Watt meter.

IMHO: O.S. is a bit late to the electric party.

I hope they stick with glow / gas.

...I run my touring car in the dirt intentionally. I don't care if there's two inches of snow on the ground, I don't care if it's raining, I don't care if it's 120 degrees outside, I don't care how sticky the mud is, if I want to run I'm taking something outside. As a result I'm not easy on equipment. I absolutely require gear I know I can beat the living hell out of and not harm it, something my OS engines are quite apt to give me. My aircraft will all be fuel powered, park flyer to giant scale, but I don't think I'd mind too much an OS powered Globe Liner or Mini Trophy Truck powersliding around my driveway.

So have you had an electric motor fail due to anything other than overloading?

I've drowned a few, yes. Admittedly they were in Mini-Zs and brushed, but yes, I have. Surprised I didn't damage the electronics when I drove the Overlands through standing water up to their adorable little wheel nuts Funny thing is, one of those Overlands I put a 16oz metal body on, which for a 1/28th scale is EXTREMELY heavy, and that didn't harm the motor at all. It just shrugged off the overloading. I was even carving donuts with it. No, what killed it was one too many swims. When I pulled the endbell off after it siezed I found the brushes absolutely caked with mud, there was more mud in the motor's windings, and it was clear the armature and magnets had been machining one another down thanks to a layer of mud that had bridged the gap between them.


Still, I demand reliability out of my gear and I demand durability. It's why I spent a premium on an OS engine when the CEN NT16 that came with my monster truck blew up. I could have just put a crankshaft in it, the failure was simply the threaded portion outside the crankcase snapping off, and been back on the road, but I decided I wanted an engine I wouldn't be able to kill. Two and a half gallons later that same engine is still running quite well.

So far from what I've seen of O.S.'s motors, they are no different than others.

That's not to say they are bad, but there is nothing I can see that will distinguish them in the market, ergo their being late to the party.
