Savox on boosters seem to work better, but the guy asked about Savox on a 1S compatible speedo!
I ma sure there are plenty of people out there with Savox servos working OK on 1S. Nonetheless, you see that phrase "and a Savox servo" so often when 1S issues arise that it says to me avoid them for that application.
Aonther reason to avoid them is that they place the spindle very close to one end and it is almost impossible to mount them correctly in a 12th or GT12 without giving you a weight distribution headache. They can be made to fit a GT12, but they simply won't fit into the vast majority of 12th cars.
There's a reason why a trip round any 12th pit will reveal that everyone uses Futaba or JR...
