Nick Holmes 2 Posted December 22, 2008 Share Posted December 22, 2008 Hi. I have a Futaba 7c 2.4GHZ system, I am told if I use a 6 volt RX battery power my S3152 Digita servis will have greater torque. Is it ok to use a 6.0v battery with this system and S3152 servos? Has anyone ever had any problems? Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted December 22, 2008 Share Posted December 22, 2008 Speed: .22 sec/60° @ 4.8V, .18 sec/60° @ 6V Torque: 69 oz-in @ 4.8V, 87 oz-in @ 6V Weight: 1.5oz (42g) Length: 1.6" (41mm) Width: 0.8" (20mm) Height: 1.5" (38mm)Remember that using 6V will use more power, so quite likely LESS duration for the same capacity 4 cell pack. The reciver is fine on 6V or even higher....and these are indeed 6V capable servos. WHY do you want / need to use 6V ? Quote Link to comment Share on other sites More sharing options...
Nick Holmes 2 Posted December 23, 2008 Author Share Posted December 23, 2008 Thanks for the reply, have put the servos, S3152's, into a Hanger 9 showtime 4d 90 which I was advised by TJD Models were good enough for the job, however reading the Hanger 9 instructions it states they should be a minimum of 80oz torque hence me thinking I should use a 6v RX bettery toi give me 87oz-oin torque. what do you think?.

Tim Mackey Posted December 23, 2008 Share Posted December 23, 2008 Well just my opinion of course...but a stronger servo is probably better TBH. The specs of the 3152 may well claim 87oz @ 6V, but remeber these torque figures are as measured at the innermost hole of the servo arm usually, and for a 3d machine especially, you may well end up using outer holes, or indeed longer than standard arms, with a resultant dropping in torque, the "further out" you go on the arm.

Nick Holmes 2 Posted December 24, 2008 Author Share Posted December 24, 2008 Thanks for that, any reccommendation on servo to use? Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted December 24, 2008 Share Posted December 24, 2008 Well there is wide range availbale Nick, and many people have personal favs, - HiTec make pretty good servos actually, as do JR and MPX as well as Futaba. Check out the huge range available at webbies "servo shop" Link here.How about this ? 150+ oz torque and decent ball raced output shaft.'Course...depends on your budget.
