Rating:
Application(s): 900 mm 400 gram EPP flying wing, 1230mm 740 gram high speed EPO flying wing.
Comments: This is an excellent servo surpassed by only one other servo "for the money" IMO but it has one flaw not affected when used in an EPP wing but will show up when used with a helicopter that crashes and that is the light weight case is relatively weak. It specs show it to be faster than the fast Futaba 7.9 gram S3114 with plastic gears and it's digital counterparts by .01 sec/60 but the torque is rated at only 1.3/1.6 kg-cm which is .01 kg-cm or 1.5-oz in less than the Futaba S3114 that has what certainly appears to be a far weaker case. It is a direct replacement for a more powerful servo so I believe the specs take the light weight case into consideration and it's intended use as a helicopter servo. The ones I've owned have no play in the metal gears. There are better servos but you will pay for that 2 to 1 and the 3020 has a better track record in use disregarding a crash.

Application(s): tail servo on a trex 450
Comments: great servo but the upper case where the mounting tabs are is junk, broke like an egg shell...had 2 of these to do that.
