Hmm could be. Im about to put my 60mm medusa in the truck. If it runs cooler then the Neu has to be sent in for a checkup lol.

edit, it was geared for about 55, think that would be worth mentioning:whistle::yes:

Eh, I don't think its that bad. Esp for harder bashing and racing. Spd runs actually keeps things cooler, but the dynamic nature of racing/bashing tends produce more heat.
How is the setup? If you are driving in the grass, driving very hard, or have heavy tires or such I would expect it to get up there in temp.

How is the esc temp? If its quite cool you may want to gear up a bit and put more load on. That can help sometimes depending on what's going on.

No worries, anything equal or less than 165 degrees has no negative affect on the motors. Two things control temperature, gear ration and motor timing. Unlike other systems lowering timing advance on our systems does not really affect performance. It affects motor efficiency. There might be a mild hit in performance but when you already have too much torque it is not really noticeable. I always run 'Lowest' timing as I don't like wrenching or worrying about equipment. Try it, you'll like it.

I wonder why gearing lower increases brushless temps? You would think less load less heat. Do they just not like to spin free?

Thanks Bernie ill run her at 160 and be happy lol

I am looking at putting all ceramic bearings on my e-revo. Will it void warrenty if I get a good set of ceramic bearings for the castle 1515 1y? If not what ones would be recommended?

if you talking about the truck itself, stay stock in my opinion. Ive tried boca ceramic and acer and they all lasted half as long as the stock traxxas ones.

weird....i run the 1515 1y/f in my 8ight on 4s 5000mah zippys/neus/thunderpowers geared 15/45 and after 3 straight packs the Mamba monster=165 the batteries=95 the the motor=130......as always check for binding.... :) oh yeah and i don't run a fan on my v1 mambe monster.... :) just the CC BEC

WOW Dragonfueled , I didnt expect to hear that:surprised: So much for them being better? I guess Im not going that route. I had boca ceramics in my xxx-t mf2 and they were awsome but it doesnt abuse bearings like a mt does. Thanks You just saved me alot of money:yipi:

I dont think they are sealed as well. The trans was fine but anything that encountered dirt went south pretty fast

Does he have any recommendations for the Y wind motors?

The ones for the xxx-t were sealed with a rubber gasket?

I must have misspoke. Small pinion large spur equals low hear, large pinion, small spur more heat. Lowering pinion size lowers heat. Lowering timing lowers heat with less change on performance.

i run my 1y on 6 cell lipo and its crazy:gasp:weelies this all i can write:lol:and 57mph of fun:yes:very nice settup but (i think to powerful for beginner on 6 cell)


mamba monsterv1 90f(30min)motor 120f and the lipo are 97f:whip:

On my 2 pole feigao 7xl the timing is worth 1.5mph in each direction. I have gps'd it. At lowest timing I'm 37.5-38mph, next timing 39-39.5 and the next up was around 40.5-41mph. I havent tried highest timing yet but I have heard 2 pole motors are most efficient at the highest timing.

I will be running the 2200 on 4s as I have too much money invested in 2S packs. I've just decided that 45mph is fast enough for an MT. I cant wait for this motor to come out. My 7xl is insanely fast. If everything I have been reading is true then this motor puts it to shame.
