HS-7954 alternatives

[Flyingjon]

Good evening to all! I've been going over my AW Freestyle 260 30cc and considering doing a rudder servo update. I'm running a 5585 in it now, but I'm considering a 7954. It gets pretty hard use and I'm running a 2s lips setup so I need high voltage. Is there a different servo I should consider?

Thanks to all for the helpful information on this site!

If you are looking to stay Hitec the HS-7955 is a great servo with titanium gear. Savox SV-1270TG is great servo for that size air frame and comes in with a bit more torque at about 487. I have run the 7954, 7955, the Savox in that size air frame with great success. I don't think you could go wrong with either one.

Savox or MKS gets a lot of thumbs up from members here and elsewhere.

Thanks for the suggestions guys. The way I understand it, the Savox and MKS have a different number of splines on the output shaft. I may stick with Hitec to keep the same SWB arm.

You are correct. MKS and Savox use 25T Futaba splines. Hitec is 24T except for the HS-8xxx or HSB-9xxx series servos which use 25T.

One thing I just noticed is that the 7955 is not a HV servo. This surprises me a bit but....

@Flyingjon the 7955 are HV just not stickered HV

Thanks for the clarification. I was almost sure that I'd seen them in a HV application but figured I must be wrong. @ChickenBalls do you know the HV torque/speed specs in those?

I think or my guess is the 7955 is 403oz at 7.2 the 7954's are same specs, other than 54 is metal gears, and 55 is titainium

I'm 99% sure the 7955 has the same torque specs as the 7954 which is right around 400 oz/in on 7.4v.
