What Neu Motor for CRT?
 

Hi Guys.

I might convert my Jammin' CRT to Brushless and screw Nitro for good!

1. What Neu motor is the best combo of Speed/Torque?

2. What Gearing is the best for staying cool and a good Speed/Torque Combo?

Thanks Guys.

I'm a fan of the 1515 2.5D/F 5/6s on appropriate gearing - use brian's calc

Ok, Thanks.

What the Differential Ratio?

Divide the diff ring-gear tooth count by the diff pinion gear tooth count.

And once you find out the tooth counts, let me know and I'll add it to the calc (note: I need the tooth counts, not the resulting ratio).

I can't find the Ring Gear and Diff Pinion anywhere.

I run a Neu 1515/1Y/F on 4S geared at 13:62.

Did you try looking in the manual? Ofna is usually pretty good about putting tooth counts either in the exploded views or in the parts list.

43/13 Iirc

Yip - checked in manual http://ofna.com/pdf/34963-x1crt-pro.pdf Page 1 & 2

How fast is the Truck going?

I also run a Neu 1515 1/y/f on 4s geared 14:62, I would guess it hits 35-37mph.(this is in a crt)

Bye:mdr:

1. How about on 6s? How much faster will it go?

2. Would the 1515/2.5d be faster?

Not Fabio..........lol

You've got to run lipos buddy.

Neu 1515/1Y/F on 4S is the fastest, cheapest route probably...

I am running Lipo.

What do you guys say?

1515/1Y on 4s?

or

1515/2.5D on 6s?

36mph according to my GPS. With the temps I get though, it could easily be geared for 40+mph and be within an acceptable temp range.

Not bad.

Is a 2.5D on 6s faster?
