New SS13.5 Pro Stock Brushless Motor
#197
I used to have two fans (motor + ESC). I have no fan now - removed them because of balance and weight issues. No problem so far. ESC (sphere comp 07) comes out about 100F motor (geared to the moon) 140-150F. This is after two club nights.

Last night, I saw a 13.5 with GTB and fan get cooked using 4.25 gearing on our outdoor asphalt track. Weather was cool (under 60 degrees).
Because there are three windings inside the can, I took temps at three points around the can. Two were under 140 degrees and one was over 165 degrees (after about 3 minutes or so). That's where the windings had failed.
And now I know how one smells after being cooked.

The windings on one pole of the can were cooked. Now, I know how one smells after doing so.

Let's put it this way. I have the fastest 13.5 at the track...and he was keeping up with me on the back straight at NorCal Hobbies asphalt.
With an LRP Sphere Comp 2007 (no fan) , I have never come off of the track hot. But, I draw the line at 4.75 for our current track layout. 4.5 tops!

I am all LRP Sphere Comp 2007 because it does not need (or have) fan for my needs 13.5 and 10.5 motors. Just received the 10.5 version yesterday.

13.5
Has anybody tested the new 13.5 pro stock motor with the fixed timming ring to the none ribbed 13.5 stock motor with a sinnited rotor in it?
which one is better
which one is better

The new motors do not have "Fixed" timing. Just the colored "non removable" ring. Not "non movable". Non Removable. .
You can run the GTB with No Fan for 10.5 and 13.5 for almost any application.
A failure is one thing, I don't think it was related to a problem, maybe just a motor or ESC dying.

An original 13.5 with a Sintered Rotor is the Same as a SS13.5Pro on the dyno.
An original SS4300 with a sintered Rotor is the same as an SS10.5Pro on the dyno.
The ONLY DIFFERENCE is the Rotor and the Ribbed Endbells. The Rotor is the big deal, the endbells look cool and are slightly less weight.
Did I mention you can always email us directly.

I ran mine for the first time tonight using a Sphere Comp esc and an Orion Lipo. Used a 19t pinion in my XXX-T MF2. Motor was barely even warm to the touch. Do I keep gearing up until it gets warm? Its cool out, 6 degrees C, but after 20 minutes of almost continuous full throttle, it was barely warmer than ambient.

In case you hadn't heard by now Novak sneaked in the li-po cut off circuitry at the last minute on the Spread Spectrum GTB's. I say that because I had been checking out this model for a month or so. And only when I ordered it (it just started shipping) did I happen to notice it show up in the Novak web pages. The documentation that I got with my GTB had a last minute sheet of paper that was obviously added at the last minute talking about it.
This is one great ESC!!!1

Gearing
Ok, I must be really missing something. I hear you guys talking about running final drive ratios under 5:1. I remember running my stock motor ration around the upper 6es. My original Losi XXX-S manual suggests running a stock motor at around 7ish. What am I missing?
I just got a 13.5 Pro and was wondering how to gear it. I had a 4300 before running it at 7.486:1. Just bashing around (unoffical races with buddie) in a parking lot with a mid sized track.
Any help on gearing would be appreciated.
