So Novak or LRP? Which one seems too run better? Which has the better features? Or is it a toss up?

i was running 3800's, thats most probally why i kept up. i was definately not the better driver. and my gearing was the same as the people with brushless (there abouts!)

anyway i dont believe that working on a motor is that hard. plus with a brushless u have no choice betwwen winds once you buy it.

just became available, but expect more choices in the future....

huh? You can change the winds on a brushless motor if you are in to winding your own. Do you rewind your mod motors? Or just buy a motor with different winds... Same choices there regardless of motor design. A brushless motor will likely last longer though.

Talking

i was wondering what kind of top speed you guys are seeing from using a setup like the novak 5.5 or the reedy neo motors.
im thinking of geting a brushless system for my rs4 rally.
it would be cool if i could smoke my friends nitro rs4!!

Cool

I know it probably isnt possible, but wouldn't it be cool to have an rs4 rally(or any car for that matter) that was able to go like...90 m.p.h. and run for 2 hours or something by using a brushless motor and a lipo battery it would be the coolest thing!!!

Acceleration/torque wise the 5.5 will outperform an RS4, but after a few more feet the RS4 would be gone. Engines have a higher top end then electric motors.

There are other systems out there to look at besides the Novak/LRP systems. The sensorless systems like Lehner, MGM, Feigao etc would be much better if speed was your only goal.

Engines do not have a higher top end than motors. How many engines can run at 50,000 RPM and survive? One reason why all the RC land speed records are electric.

The reason why I said engines have a higher top end is because you can gear them a lot higher then an electric motor. If an electric motor could be geared and could handle 230* temperatures without burning up, then electric would most likely have a higher top speed, but then again you could always add on a few more cells.

You are right about electric being used the most for land speed records.

i run my car with a 14 turn speed gems motor. it used to also have a futaba esc, but that blew up the other day. i dont know why. with that setup, it did leave my friends nitro rs4 for maybe the first 40 feet, but after that he would catch up and i would have to do a u turn so it didn't look like i got dusted so badly. my top speed was a decent 34 m.p.h. i hope i could go 45 with a nice brushless system. which would be good for that?

so which esc will fit?
how much are they with the esc?
so there are 2 wires are for batteries, 2 are for motor, rigth?
and can it go reverse?
thanks

any brushless esc should fit in your car. they are about the same size as a regular brushed esc. some ive seen are smaller. i'd only worry about the extra wires for the motor(3 power wires and sensor wires) having clearance from drive belts,shafts and gears. and they can go in reverse, but i think that some of them have a reverse lock out feature for legal race use.

so you are saying that there are 4 wires to the motor
so what does hte sensor wire do? and why does it need 3 power wires?

okay, the motor has three wires for power. then also connected to the motor are a few small wires(about three wires similar in size to reciever or servo leads.) these small wires are sensor wires. the brushless motor uses sensors to determine rotor position. the sensor wires connect to the speed controller. as for the third main power wire, im not certain, but i do know 2 of the 3 wires can be reversed to reverse motor direction. there are brushless motors that do not have sensor wires, like the HACKER motors, but from what i understand, a sensor based brushless motor offers smoother low speed control. all this talk of brushless motors really makes me wish i could run my car...period!
