| Here's a good rule of thumb:
^^^^ obviously you meant to say `bad'. Hope this helps.
| Take the price of a typical glow engine - let's say a .40. Take the
| price that it sells at - let's say $80. Triple the price - $240.
Ok, 0.049 glow engine. That's pretty typical, right? Price is about
$50. Triple that is $150. Except that I can get similar performance
out of a $10 motor. If the $10 motor can't do it, a $40 cobalt motor
| Find an electric motor that is $240. There is your equivalent!
Actually for a larger electric, it's the battery pack that really
costs a lot of money, not the motor. The motor prices tend to taper
off, but the battery price doubles when you double the price, and the
ESC price goes up as well, but not quite double.
| Although you will need those formulas to calculate what the appropriate
| battery, prop and gear ratio should be.
I think that's what they were after.
