kostaktinos_mt, Thanks for the quick education on the in's and out's of surface brushless systems. You gave me some good info to consider. It certainly makes sence that the bearings will have much more dirt and crud to deal with in a truck than in my helis, and planes. Unfortunatly I'm having a hard time accepting this. I basicly need to throw all my ingrained experiance from aircraft out the door and accept what you guys have learned through trial and error.

But as an experiment I think this was worth the time, just from the respect that I now know I dont need 2000+watts to match the performance of my FLM EXT Big block T. Since nothing has been purchased specificly for the E-maxx yet I learned a cheap lesson with the Ammo!!

Weather has been cold and wet all week so I haven't had a chance to drive since Sunday night. But I have been thinking hard. With trying to keep the motor RPM's down around 30k, how do outrunner motors do in surface vehicles?? I know most larger helis(See I cant let it go) use outrunners because they tend to produce the best power at around 30k which lets the heli guys run a larger pinion with more teeth contacting the main gear, it's very rare in helis to see inrunners geared for less than high 30k rpm's.

http://www.innov8tivedesigns.com/ind...cPath=21_25_65 I'm thinking the 1400kv on 8s A123 or the 1900kv on 6s A123.

I could also drop to a 4s A123 pack with the Medusa to get the RPM below 40k, I think the drop in available watts would be too much though, unless the medusa can stand 110+a bursts. I did plan to try it on 4s and still will, 19t/65t combo looks decent for top speeds

I believe Medusa was up and running before Neu, so the V1's were probably more Aveox copies, the V2's could be influanced by the Neu design. Since Neu took over the Aveox model motors it makes sence that all these motors would resemble each other.

I agree with the 70-75mm Medusa, I had almost discounted them because of their lack of size. When I siezed the bearing in the Ammo I ordered the Medusa as a replacement before I even checked the Ammo out to see what happened, figured the rotor let loose.
