So I figured I would try one of these cheap RC Gear Shop 3900kv motors from Tower hobbies. In a word, AWESOME ! Installed the motor and took it for a spin up and down the street. This truck HAULS with 86/23 gearing. I'm using a Hobbywing WP SC8 ESC. I had a Dynamite Tazer 3300kv (86/23)in there before. I needed the Taser for a different vehicle. It actually worked great in the Slash, but the 3900kv is better. It's got more torque and has much more top end.

If anyone is looking for a Great brushless, sensorless motor for their slash. I would highly recommend this motor. Just so you know I was running WOT up and down my street and thru short grass and dirt for a 6500mah SMC battery pack and I could put my hand on the motor. It was just warm, and I was running it at 70 degree ambient outside temp.

This would be a good spare for sure. To bad they make the motor wires so short.
hate soldering

I agree, They are short. Fortunately my hobbywing ESC wires are a little longer to make up the difference. I suck at soldering so I have a friend of mine who works at my LHS do my soldering for me. He's a pro and does it super quick. I should practice to get better at it though. I really don't like to rely on others

at $10 I guess this might be worth the hassle of not using the iron.

Learn to solder. It's a requirement if you're going to stay in the hobby. Not only will it save you money doing it yourself, you won't have to wait for a shop to do it or shipping for some extra-resistance-adding adapter.

Also, absolutely love my rc Gearshop motor as well. I've got the 2150kv one for my 8th buggy and the thing runs great. Powerful and fast, runs cool.

I agree. I know how to solder, I just suck at it. Maybe if I had a better iron it would be easier. Any recommendations?

Is the soldering iron I use/learned on. I really like it, get a chisel tip though, it will help alot.

Thanks. I guess it's time to Pony up and get a real soldering iron. The iron that I have now has a pointed tip. Honestly, it sucks. It's a $20 Radio Shack special
