Express Motorsports modified Trinity brushless motors?

[shelljeep]

I'm switching to brushless in my Losi, had made up my mind to try out the Trinity Nemesis 19.5T Crawler but it is out of stock everywhere I looked.
I came across some Trinity motors that have been worked over by Express Motorsports. Have read good things about the Trinity motors on here but I don't know anything about Express Motorsports.
Think any of these would be a good motor for my crawler?
Anyone know what Express does to these to tweak them?
Here's a link to a Duo 2 based 21.5T: Clicky
And these are two 17.5T's: Ninja 17.5T based off the Nemesis line
and this 17.5T based off the Duo 2
Looking for strong torque, combined with lots of wheelspeed. Would like to be able to jump short gaps if needed. Was running a 10T puller on 4s and would have been satisfied if I could have kept the motor alive.
Will be running the brushless through a MM Pro, have 4s and 3s to play with and pinions from 12-16.
Thanks!

From what I have read on the Nemesis motors by Trinity, I would shy away from them unless they are the crawler specific ones. What I read pointed to the Nemesis being a definite RPM motor, which would not be the best in the Losi. After my 17.5 shorted out and let out the magic smoke, I tried the 21.5 Tekin and have been pretty happy with it. Smoother than the 17.5 on the bottom end but not quite the top end. Top end is still really good, just not quite the pop of the 17.5. If you go with the 17.5 Duo2, then I would recommend a 13t pinion. A 12t pinion works on the 17.5 really well, but the mesh is just barely adequate and you can eat idler gears if you get bound up, trust me on that one. With the 21.5 I would recommend starting with a 15t pinion. I really don't think you can go wrong with either of the choices, but the bottom end of the 21.5t is where I am staying at for right now.

Thanks Dave, going with the 21.5T then. Now if I could just find a MM Pro in stock somewhere.

Yeah, I cut down the grub screw in the 12 tooth pinion that I was running behind the puller. Let me engage the full width of the idler gear. I switched out to all metal gears in the tranny also. Stripped the stock idler with the puller, said once was enough.
What do you mean by staying on the bottom end of the 21.5? Just running a smaller pinion then you might normally try?

Ordered a Mamba Max Pro last night from HH, should be here in a couple days."thumbsup"
I think he's the only place that has them in stock and available right now.

Poor choice of wording. I meant that for now I am staying with the 21.5 because I like the smoothness and power on the bottom end of it better than the 17.5. And the wheelspeed is good enough for 95% of what I need. Playing with the CHEAT feature in the MMP to gain some top end if I need it, not sure of the results just yet.

Cool, thanks for the clarifification. Hoping my parts are here by the weekend, chose fast shipping on all of it so we will see.

Haha....you have about as much patience as I do!:mrgreen:

I'm about to make a friendly phonecall to make sure they are aware of my order also.:mrgreen: Funny, this rc stuff is the only thing I get so antsy about. Everything else gets the slooow cheap option for shipping.
