RE: Our Aeromarine and Blackjack 55 continual builds...
Futaba
s3050 spec say: @ approx. $50.00
Torque: 72 oz-in @ 4.8V 90 oz-in @ 6V
much different than the standard s3004 that is approximately $15.00
the s3010 is less with same torque spec @ approximately $25.00 but is analog vs. s3050 digital.
I can't seem to find a futaba s3020 ???
I think the stock JR were 80 @ 6V.
I didn't clarify the s6020's were spektrum at 128 in-oz @ 6V not a futaba
