So one servo per all control surfaces. I like the HV option on these servos for using a LiPo or Lion in the future as well.


Does anybody know what the "unique" means when they are talking about their steel gear train?


Should I be worried about wear in a steel gear servo vs titanium in a small single gasser?


SAVOX
SB-2273SG $98 6V 0.12/319.4 Brushless, Steel Gears (Fast enough for hesitation rolls, & strong) Haven't seen many people use this servo, curious what everyone here thinks.


SV-1270TG $98 6V 0.14/361.1 Coreless, Titanium Gears (Bit slower - but still fast, great torque).
Proven Servo, comparable to HiTec 7955's IMO but slightly faster and stronger.


Curious if I should go with the speed, or torque. Reliability seems to be the same as well with the cost. If I went with a single A123 for Rx and Ign, the drain would be lower on the brushless which means for flight time and could get away with using a single A123.
Look at the Savox 1272SG HV CORELESS DIGITAL SERVO .10/416.6 STANDARD SIZE 7.4V
Also $98 retail
or call me 314-256-9987 I sell many manufactures: JR, Hitec, MKS, Savox

Thanks,
I think the 1270 could be better with the titanium gears in comparison, they have a higher torque, and 1/100 of a second slower than the 1272. I'm looking at 6V specs for an A123 batt. If I was choosing between two steel gear servos (2273 vs 1272) I'd think the brush-less wins in speed, power consumption, same torque and price.

What about a 1256TG - 0.15/277 and cheaper too.Plenty For a 50cc as well.

Sir,
The 1270TG is the best option as it will definitely move up with you as you move up in airplane. These servos will work in 50cc, 60cc, and 100 cc planes. The unique steel gear train is Savox's version of metal alloys to limit gear train wear. Both the Titanium coated gear train and unique steel gear trains are good. I like the versatility of the 1270 if you think you may want to move the servos from the 30cc plane to something larger in the future. Send me a PM and I will quote you some prices on the servos which are in stock ready to be delivered.


Thanks
Brian

You guys are confirming all my research on these servos! I was originally thinking SA1256TG in the wings but can they run on HV? SupaTim has an AJ 73" with these servos and the video he posted was outstanding.

I have seen lots of good reviews for the 1270's I feel like its the upgrade from a 1256, higher toque, and a bit more speed. My fear is compromising torque for speed, and I like the idea of the 2273 where the toque is right in between the 1256 and the 1270 and the speed is a bit better at the same cost as a 1270... servo decisions!!! ah! Any known issues I'm missing? drawbacks to any of these three servos or am I just way over thinking this and should just buy some servos. ha!
Maybe: 1256 ail (if they can handle HV?), 1270 rud, 2273elev

Thanks for explaining the unique steel gearing, that makes sense.

Unfortunately Not, There 6v, The 1270 Seams like the servo for you

What is your experience with those 0251 MG? It is used in scale warbird planes and not in a precision 3D/Imac plane.

I'm also looking for servos for a 60cc H9 Corsair. I'd like to go HV but there doesn't seem to be any mid-range affordable HV servos. I'm looking for something in the 150-200 oz range. I also need some micro servos for the gear doors.

Is there a Savox equivelent to the Spektrum 6150's? I have a Savox 1267 I plan on using for the rudder. My retracts want HV and I already have HV throttle and retract servos so that's the reason for the HV preference. I need them to be reliable and don't mind paying for reliability so if I need to go with something like 1267's or even 1270's that's what I'll do.
