Hi guys

I am about to build a Showtime .50, I am going to use an O.S. 91 Surpass engine and I was thinking in using mini servos to save some weight but i don't know if i am going to have to much problems mounting the servos as the openings in the plane are for standar size servos has anyone tried to use them?, also i was thinking in the balance i don't want to add any extra wight to the plane so what do you guys think? should i use them?or should I get some good standar servos?

The servos I am planing to use are these ones http://www3.towerhobbies.com/cgi-bin...&I=LXLN95&P=SM
