Sorry, i don't understand, could you explain in detail, please?

The motor coolers like the muchmore cooler/chiller and people using canned air upside down on motors prior to running them to have them start off cooler. We found to be the cause of motors failing. This was on an outdoor track. So our only guess was perhaps the difference in temperature was causing condensation in the motors and causing them to fry. Once everyone stopped doing that then no more fried motors. It was counterintuitive so it took a while to figure out.

Your best bet is just to gear correctly and monitor the temperature. Small fans placed behind the motor do wonders to keep it cool. I would just stay away from the motor chillers.

Interesting.. I have never seen a failure using one of these.. but I did mostly use it indoors. You are in Ohio though.. how hot was it outside when you guys saw these failures? Was this in brushless motors or brushed motors?

We used them extensively earlier in stock class with brushed motors without any problems. With BL we have not used them...

You mean the motor failed from to condition of cooling before then warming during the running, through that MM motor cooler, isn't it?
Looks like that motor cooler is really weird.
Maybe i will not use it, due i am racing in warmy and humid asian weather condition.

Thanks for your recommend!

Brushless. Outdoor temps in the 80s and 90s in the summer.

Yeah, our guess is the cooling of the motor (these things can put a frost on your motor) then the rapid warming of them from running them seemed to cause something to go wrong in the motor and they would fry on us.

Some people have said they have used them indoors without problems so I thought was that it must have something to do with the difference in temperatures. All I know is once everyone stopped using them then we didn't have anymore motors go bad.

I believe some electronics components will have own reaction in some determined temperature condition, just depended the material of they are made, ex: ceramic.

Do any of the LRP folks know when Tower will be getting their next shipment of X-12 17.5 motors? Been on back-order for a while and just wondering when I can expect to see it...

For my fellow Europeans, looks like the first batches hit the Ebay stores in Germany for 219 Euros.

US price that I've found so far is 240 $ = 175 Euros
But it looks like the US stores are already waiting on the 2nd batch since
the 1st batch went to the pre-orders.

Buying as I type

Default timing inserts

just abit confused about changing timing on the x12 motors.

dont have one yet, but I hear you need to change inserts or something to change timing. Whats the deal with that?

do all the inserts come with the motor as standard?

Yes, they come with it. You remove a single screw, remove the back plate, swap the insert then reattach. Very easy to do. LRP does it to make sure the sensor is precisely aligned.

My question is... if you want the 3 dot insert... should the dots be visible from outside the motor or inside the motor? Depending on which insert you use, this could flip the timing the opposite direction.

I installed my timing insert so the dots were visible outside the backplate. I just havent run it since i made the change.
