Id like to try to avoid the 2 (apparently) top 10 drivers in the nation in that class.
i know where you noramlly race... so running 13.5 is going to be hard for you be the guys here don't want to run rubber tires for some reason...hint the reason why 10.5 is strickly a rubber tire class

Congrats to Kyle and Hacker on their 12th scale NC! The car and driver looked great on the track all weekend. Power didnt look like an issue at all either!

Thanks for the motors this weekend Kyle. Wish I would have tried the 17.5 a little earlier in the week to get it right. I'll be playing with it in the next few weeks and let you know how it goes.

Anyone looking to try Hacker BL motors they are great products and have awesome customer support as well!

Thanks
EA

Hacker 17.5 w/nimh's made a great combo at the Nats.

I second Eric's comments. Kyle won 12th scale, but he also placed third in super stock tc. Congrats Kyle and thanks for the support.....

Kyle- nice meeting you and Jason E at the Nats. Great job on the Championship and other finishes for both of you.

I stopped by Dave's house and dropped off the motor you gave him from your 12th scale. I handed it to him and he said "what's this for?" I told him KB said "his junk looked so bad, maybe if he has a decent motor, he can build a new car around it!!" LMAO

Not sure if he'll have time to get on rctech, but in case he doesn't, he said thanks a million- you guys are definately a class act.

Oh yea, and next time your "big hair" is blocking the whole sweeper you gotta squat down!!!!

I have been running the Hacker 13.5 and 17.5 since Nats in March and love them. But over the last month both motors with the same gearing as before are coming off at 210 degrees. No lack in performance just super hot. I tried gearing back from (17.5 -3.56 FDR) to (17.5 - 4.2 FDR) and still was in the 170s and way way slower. Wondering if any one else is seeing the same thing? I finally have stopped caring about the temp and just gear them till there sluggish than step one gear back. Figure if it thermals fine. Least I am not slow. Is this normal once they have broke in or did I break them?

Same ESC and ESC settings/timing? On my Novak motor last week I got a 40 degree swing (up) just by switching my Tekin RS from hybrid mode to sensored only.

Ya nothing different. I even suspected the same and went through and reset my speed control. Tomorrow I am going to test my Novac 17.5 and see if I get similar results to rule out everything except the motor. Is it possible I could have overworked them and they lost there mojo. Is the super hot temps a common sign off a shot brushless motor?

Denver,

It seems you may have got the motor to the point where it started to loose its magnet strength. If the motor looses its strenth it will increase the RPM of the motor as well increase the amp draw. The power will go down if this happens. You might want to consider replacing the rotor. We have them in stock if needed.

The office number is (480) 726-7519. You can call 8AM-4PM MST

If you dont think it is the rotor you could always send it to us to have it checked out.

I kind of suspected the that. I thought I had read something that if you got them too hot it weaken the magnet. Thanks for the info. I will hit you up in the am about replacement rotors.

I'm going to borrow a 17.5 for a little racing in a few days. Any suggestions on ballpark rollout? Short track, carpet.

What car are you going to be running?
If Sedan are you running rubber tires or foam?

Kyle,

I'll be running a sedan (416) with rubber tires on a small carpet track. Thanks!

Depending on how small the track is layed out, I would start around a 5.5fdr.

Denver, something else to check is the bearings in the car. My Vintage Trans-Am with the 17.5 has started to show more Temp and slowed down. Pulled all the bearings in the car and found two that were crap!!
