My BL Revo project

[BrianG]

dafni,

Thanks!

I see you're pretty popular around here! I guess if i'm going to choose a design to emulate, it's gotta be from someone popular!

Like I said, I read some FAQ pages on BL motors and understand them for the most part, except for the questions I asked above.

I've read a bit about BL motor parameters in general, so I know that Max_RPM = kV * Total_batt_voltage, but is there a parameter that shows the torque rating? I've seen some motors do list the spec, but most don't. Is there a way to calculate it? For example, take the Feigao chart, there are columns for "Max Amps", "Resistance", "RPM/V", and "IO(A)" - nothing about torque. Also, what is the "IO(A)" rating?

Also, I notice all BL motors have three main wires (sensor wires excluded for those models). I assume this is because the motor coils are in delta configuration?

nbcazmaster,
You should've seen the chassis before the paint! It was all scratched and dinged up from working on it. It's amazing what a little filing/dremeling and paint can hide! ;)


Now for more questions:

- As stated before, I'll be going with an Emaxx tranny. I've heard people talk about making the emaxx tranny one speed. To do this, while being able to take the torque or the BL, this is what I've come up with for parts:
Idler Gear: http://www.rc-monster.com/proddetail...03idler&cat=40
GMaxx Conversion: http://www.rc-monster.com/proddetail...R-AL-WS&cat=10
Would I use stock parts for the other tranny gears?

- What is recommended for a slipper system that is durable and relatively trouble-free?

- If I do stick with a single speed tranny, I want to find a pinion/spur tooth count that will give me lots of power, no more than 25ish MPH, and not cause motor overheating. If this is not attainable, I'll probably stick with a two speed tranny providing I can find the parts to build one strong enough.

Thanks in advance!
