mako,

The specs come from Tower Hobbies and are the current, updated specs that have yet to be published at Servo City or, for that matter, Hitec. I purchased (4) 5625s and (1) 5645 for my H9 1/4-scale Cap 232. The new specs are on the boxes, labels applied over the old specs. With the new specs they are the most cost effective digital servos in existance. I went the whole gambit and also bought the Hitec Servo Programmer. The (5) digital servos and programmer ran me $421.00 at J&C Hobbies.
The programmer not only programs Hitec digital servos but also checks any brand of servo with a Manual test and Auto scan. Plus it will check the Pulse width and Voltage. Checks the transmitter signal pulse as well.
