RE: servo speed
Dick, Mike, thanks for the answers.
My question is if I will notice the difference between a 0.22 sec servo and a 0.14 sec servo, given a fix torque. That is considering medium priced servos, because this is going to be a "trainer" pattern plane, 90 size.
My first choice were Futabas S9001, which are coreless and has enough torque for the design. They are relatively cheap too at $29.99. But the response time is 0.22 sec. at 4.8V.
Going to faster servos means more than double the price. I would do it, but only if the difference is noticeable somehow.
I also noticed that the choices are few at this price level. There are not many options if you want to upgrade your standard servos without going "pro". For $80 and up you have plenty of possibilities betrween coreless, digitals, metal or plastic gears, more speed, more torque or more both. But if you want to stay below $40, possibilities are scarce.
Maybe the Manufacturers decided to rise the bottom price for the servos...
Thanks and regards.
