The 925 is a great throttle servo.You want at least 130+ on steering.
Most guys try to get 165 or above.
I will have to say I think the 590 and 650 are falsely rated when compared to Airtronics,Futaba or Ko.
JR does have REAL servo's but you also pay for them.
Just being honest here.
Everyone spends $90.00-130.00 for a steering servo for a reason.You will smoke cheap servo's left and right.
Dont even waste your time buying a 650 unless you dont race at ALL and wanna replace it pretty quick.
I would buy used at $60.00-70.00 before I purchased a NEW 650 for $50.00
There is NO CUTTING corners when it comes to steering servo's.
It's buy used if $60.00 is your limit.
