The ez-run systems are good stuff for sure. I have 2 of their speedos. 1 35a and 1 60a.Both perform flawlessly. It's the motors you have to be carefull on.The ones that come with their bundled systems that have the ribbed cans- stay away from!! that has a 380 size rotor in it and they run hot!! They make another motor(see pic) that is much nicer quality and it's only 10$ more than the ribbed ones.Those are the ones you want.They have a full size sintered rotor and look very like a speed passion motor as far as design. I have one of their sensorless 17.5's as my 'beater' stock motor for clubracing and practice.Works fine. You just have to gear them a couple teeth higher than say a novak or lrp 17.5 because they dont make as many rpm's as a sensored motor , but the make a ton of torque.
Both the speedo's i have have been bulletproof. They even run my sensored motors without any cogging issues.I even tried to blow up the 35A speedo running a novak 8.5 behind it on a hot august day for a full day of racing- No issues- So tthe way I figure it , if it was going to smoke , it would have smoked then!
all the brushless cars i race have them, and no problems with them so far. next to ripping diff gears up with them. i would say get the 5.5 esc set up with the programer. it can be turned down to a 17.5 i think. eather way i run my balls to the wall i cut ever thing off that can be cut off or set every thing to 0. must say if it can flip as evader ext over with slicks and wet ground then thats saying something.
what is the diffrence between the onroad and offroad systems?from what i see visualy the only thing diffrent is the motor can.i want to go with the onroad system becase its $37 cheaper.i got 1 used that was on its last leg,it was an onroad 9t 25amp esc put in a hpiblitz and was fine till esc went last week.would it be ok to get a onroad system?
