I am not sure whether this is the forum for this post but here goes...

I am considering buying servos for my Funtana, Extra 60 size and future 3D airplanes including gas. The possible candidates are below

Futaba S3305 MG (124 oz-in, 0.20 sec/60° at 6V)

Futaba S3152 (87 oz-in, .18 sec/60° @ 6V)

http://www3.towerhobbies.com/cgi-bin...&P=SU&I=LXHKB0

Futaba S3010 (90 oz-in, 0.16 sec/60° @ 6V)

Hitec HS645 MG (133.31 oz-in, 0.20 sec/60° at 6.0V)

Hitec HS625 MG (94.43 oz-in, 0.15sec/60° at 6.0V)

http://www3.towerhobbies.com/cgi-bin...?&I=LXUZ87&P=0

Hitec HS485HB (83.3 oz-in, 0.18sec/60° at 6.0V)

Now my question is which of these would be the best. I have intentionally placed the Futaba ones first as my experience with Hitec ones isint that good. But that was with the cheaper hs-311 entry level servos. I have a good stock of 3010s running well (about 5-8 of them) but since I intend to use these on the rudder and elevator, high torque would be preferable?

Also, I wanted to know what are the advantages and disadvantages of metal gear servos if those are preferable
