why are my temps so high???

Agreed. I'm sure Castle Tech support is full of general knowledge on their products, but they are not likely to be nearly as experienced in the "specifics" of the various vehicles, gearing and setup nuances. :)

I dunno. All I know is that every time I think I have this whole brushless thing figured out, I realize I know nothing. Kinda sucks, but it still beats nitro; and not only can I not afford to give up, but I refuse to! Things do seem to keep going wrong though. I completely craked a wheel and a shock tower yesterday, and I really do have to reglue all my tires and wheels after each day. Man is that getting old!

FWIW, I DID go over my entire setup with the guy, and he was definitely an older guy, with knowlege. He seemed to know quite a bit actually. I know you guys do too, so when a newbie comes along (like me), and gets different opinions, well, it makes it real hard to figure out who to go with. So, I'm gonna go back to 12T, see how hot things get, see if brake usage makes any difference (if so I'll go to mechanical brakes), and stay off the grass. If it's still too hot, then a new spur, and if THAT doesn't help, then there's a Neu motor for sale. I hope to not have to do that - major PITA (the lower kv's are still on backorder).

If you cant trust what Mike is telling you, who can you trust?

If you are litterally blowing the tires off the wheels every time you run you are certainly generating alot of power. Yes the balisic power is fun, but these trucks can only handle so much. I used to run my stuff set up for crazy power too. But in the long run found much more enjoyment from a setup that ran within the limits of the equipment. Much more up-time on the truck when you arent pushing it beyond its limits. (cheaper on the reair parts bill as well.)

Dont get me wrong, im not saying you cant run a setup with a ton of power, it just sounds like you need to back off a little bit in general for the health of everthing involved. The brushless system as well as the truck.

I DO trust and even like Mike, but shouldn't I trust CC too? I mean, when you call Neu, they even tell you to call CC for everything, b/c they're the distributor! I also trust the people on this board (especially briang and lincpimp who always seem to respond to my posts - thanks guys!), but when views differ, my head spins, escpecially since I really have no idea what the hell is going on! Maybe Mike IS more accurate; I sure don't know. I think when I picked out my components, I also leaned more towards what CC said, instead of everyone else here. I admit it; I thought you guys were being a little too conservative for me. I was wrong. Crap.

I do agree with everything you said though jhautz. The power IS addictive, BUT, I just cannot keep the front end on the ground no matter what i do w/ the 18T pinion, and I cannot keep the tires on the rims no matter what I do (DEAD SERIOUS, I'm starting to get high from ca glue!!), and I know things are gonna get shredded soon. Seriously, top speed is not possible, the front end just comes up! Also, I really want a cool running, tough as nails reliable BL system - it was the whole point of getting out of nitro - no more worries, just turn it on and run until the battery dies. I don't want to be checking temps every minute anymore.

would a step down to 4s be too much? that would surely tame those wheelies and temperatures. that is, until you are running WOT constantly and heating up the batteries too much. in the end i think everyone wants a super powerful reliable truck to the point of being ALMOST uncontrollable, to have the ability to slaughter the nitros in the parking lot, but then be able to race seriously without flipping every turn...?

Sounds like my kind of r/c...

Anyway, I have 1 neu motor ATM, a 1515 1.5d that i run on 4s in a erevo. Motor rpm is around 40k maxx. With 19/50 gearing and some taped badlands it is good for around 45mph. I think that is the best that motor will do without going over 160f. I personally think that naything heavier than that revo would require a larger motor, like a 1521...

I am also building an aftershock (lst like truck) that i plan to run 6s on. I have a hacker 11xl, but it will only spin 33k rpm on 6s. I will see how it does, but have a feeling that a 1521 1.5d (1900kv) would be a great motor to move the heavy truck around. It would spin over 40k, near 42k maxx. Or I could go with a 1521 1y (1577kv) but that would only get to around 35k max...

well, everyone is right. The cc rep is right, you can run the neus at 50k rpm all day- with a proper load. And everyone here at RCM is right. Less battery or less gear will drop your temps. But mostly, listen to Linc. Dropping the gearing will lighten the load and allow you to keep your high winding setup. It's "cool" to gear for 60mph but pretty impractical. You need a BIG space to go that fast and it's out of site in a second. Gearing for 45ish is plenty for me and I play real hard. Also playing with the punch control on the MMM can tame your wheelies down.
