I was thinking of using the JR 537 servos on my next plane, a 60 4 star. Will these servos be suffecient for the plane or do i need to go to a different servo? Thanks for your time.[sm=confused.gif]

the jr 537 servos should be fine.
im currently using them on a hangar 9 twist and the perform flawlessly

Yep, I had 537's on my 4*. They're fine.

Same for me as well. I have a 4*60 with 537's and they work fine.
