servos for truggy 1/8 ?
hi !
I'm searching for some servos for my new truggy 1/8 (gs racing XUT PRO TEAM kit).
Now, for steering I have
digital servo hitec hs-5645mg
11.1kg/cm @6V 0.18sec/60 @6V
http://www.servocity.com/html/hs-564...al_torque.html
Is this ok? or should i use someting stronger or faster ?
any good and cheap servos?
What do you thing on digital Futaba S9350
0.12sec/60, 10kg/cm @ 6V
http://www.servocity.com/html/s9350_..._steering.html
it's faster but has less torque.
maybe it's a good servo for gas/carburettor ? (nitro 4.6cc engine, sliding carburettor)

Hitec 7955. I don't trust anything else to be as durable or reliable.
Servos are one area of RC where I really do believe you're better off spending more at the outset. In the meantime there are good cheap engines, kits, etc.., but a $50 dead servo means buying another one, so you end up with a $100 average servo. Better to spend the $100 right away and never think about servos again.
If you can order from Germany, check out www.buggy-land.de . Great prices - best for the Hitec 7955 I know of. www.hk-nitroshop.de also has good prices.

thanks for links ! buggy-land has hitec 7955 15% cheaper.
Now, I'm thinking what is better, to use servos that accept even 7.4V (I hate NiMH and I want to switch to LiFe or LiPo)
or maybe use standard servos and small UBEC ?

higher voltage, faster and more powerful servos
(as you can see, servos at 4.8V are slower and weaker than at 6V)
but only newest servos can handle more than 6V (it should be specified).
with more voltage, servo will take more current (Ohm's law - http://en.wikipedia.org/wiki/Ohm%27s_law), so, power excess can result in servo failure (malfuction/burn etc.)

servo's that are designed to work with unregulated lipo will not "fail" from "excess power"
