At the risk of getting off topic, look at it this way. While just the servo alone weight savings alone doesn't make a difference, a combination of many small little weight savings add up. Or you can use the weight savings to offset other additional "creature comforts" such as a Switchglo. I know many times people argue the fact that they don't want to add a Switchglo because it adds weight. Well a Switchglo is 19grams. The additional weight from the Switchglo is now negated using a smaller, equally capable throttle servo.
I dont really see the advantage of using a mini as the weights are close. Even if its 1/2 it is still only 20-30 grams.
What about a micro like the 410's, HS56/65, 287's ect....????
I accomplished three things when I used a 9257 instead of the 8311 I had for throttle. I saved weight, saved a little cash, and added onboard glow starter convenience.Setup 1:
JR 8311 Throttle Sevo
Total Cost & Weight: $129.99 (1.87 oz / 53 grams)Setup 2:
Futaba 9257 Throttle Servo - $59.99 (0.92 oz. / 26g)
SwitchGlo - $64.99 (0.67oz / 19g)
Total Cost & Weight: $124.99 (1.59 oz / 45g grams)
I can/will save even more weight and money when I use a Perfect Regulator onboard glow driver instead of a SwitchGlo on my 90.
Don't even want to go into the details of how much I saved going from 3 x 8717, 8311, 8900, Fromeco Arizon Reg to 3 x bls451, 9257, bls251 & Perfect Regulators reg. You can add up if you'd like. You'd be surprised.
Just a thought.
