Bubba did good and those are 3D and pattern plane for sure. There are exceptions , like , if you have the room for a std size throttle servo use it. Because some throttle cables snaking around tanks, bulk heads, and firewalls bind alittle and could use the extra torque. Not to mention Perry carbs have a bit more throttle arm resistence. The other exception would be if you have a large plane with only one aleron servo and in wing cableing the strongest would be best. I just did the Joss stick 108 and decided to stay with one servo setup. Big wing with full length flaps. I put a 60OZ instead of the 44OZ. Keep in mind most small servos have only 2 screws holding them in an not all plane servo mounts are thick and strong.
