That model in the picture isn't what you'd call an "electric powered sailplane"????????????
whatever.......
It that's the model you're planning to use the servos with, the Hitec HS-81 just mentioned will work and probably fit well.
darock, i was thinking about the Hitec's Mighty Mini 225 but i've heard stories about the plast. gears stripping & the metal g. being sloppy and heavy... is it true?
Heard stories? About plastic gears in a 225? The 225s come with nylon gears like are in 75% of all the servos by all mfgs. And metal gears usually only add one or two tenths of an ounce. And no metal gear servos I've used by any mfg have been sloppy. Hitec does have a composite gear set that they use in some of their servos. The composites are something like 5 or 6 times as strong as nylon gears are and weigh the same. I use them whenever I can. I've never had one strip in use, but have had nylons strip. Guess you could call composite gears plastic, but so is nylon.
