As for your review compared to the Futaba servo, I should hope it's faster considering it's rated as being twice as fast. How about some torque comparisons since the Futaba is rated for about 50% more torque than the OMG servo you have?
Any real quantitative comparisons like actual torque output on both servos, or time measured to see how both compare to how they're supposed to perform?
You're also comparing old tech (coreless motor) to new tech (brushless motor), how about comparing to an equivalent Futaba or Savox servo (this one maybe? http://www.savoxusa.com/Savox_SB2272...sb2272mg.htm)?
Your review is like saying my 15 year old stadium truck is better than a top of the line brand new touring car because it handles jumps better.
