1: what works best on throttle on a 90size patternship, of hitec hs525bb or the futaba 3050 or jr ds811?

2: or what else servo is reccomended to give a good throttling for a man on a budget?

3: and what is actually the best servo for those kind of planes and the big 2x2? if money were no object?

I used a Hitec 225 on my 2x2. Servo was mounted on the softwmount itself. no problems in 2 years of flying.

HITEC 225! no problems at all.

are you meaning the one whit metal gear or the one whitout?

and are they precise so that the engine is running equal if I advance or decreace throttle to the same point on my transmitter, and not end alittle more throttle if it is decreased from full throttle than when it is increased from lo throttle?

both are great, I use plastic gears.

Futaba 9650 is the best in my opinion.

why? I wanna learn, so please explain why you reccomend the way you do.

I use Futaba S3101 as throttle servo on all my planes.

The 9650 is a mini digital servo with plastic gears and 4 mounting screws as opposed to the micro servos 2 mounting screws. It is also used by some for elevator servos when running a 2 servo leevator setup. This means its light, fast, strong, resistant to vibration and has great centering. Its actually a bit overkill for throttle use but it is the best, in my opinion.
