Recomended servos for gas car?

Re: Recomended servos for gas car?
The smallest and lightest receiver I've seen is from KO. I may be wrong but I believe the KO Helios has the smallest receiver in it's class.
Servos? High torque for throttle / brake and high speed for steering.
Digital servos are nice but not so for throttle / brake service and they tend to fail more easily there. Perhaps nearer to the engine vibrations. Not forgetting digital servos drain more power.
Digital servos are more accurate and have better holding power and centers better. Hence, they are better used for steering. For throttle, analog servos are better.
If it was me, go with KO 2343 (or 2143) digital servo (0.08 sec, 8 kg) for steering and KO 2174 analog servo (0.13 sec, 12 kg) for throttle / brake. My 2 cents.

Futabas....
What you really need is metal gears and bearings on your servos. Digital servo for the steering and analog for the Th/Brake. Mine choose like many others go for a combo of Futaba 9450 on the steering and a 9402 on the throttle.
Have many Futaba units with more than 3 years of services and hadn't missed a beat during this three years. In fact until two months ago where I totalled mine MRX3, the servo that was destined as a spare part remained on their original packages (well, the green carton was a little less green and probably more black. )
Just remember that KO units are Fet servos that need separate power and this complicates a little more your electrical installation. Just KISS and go with servos that doesn't need separate power lines.

i don't know what your talking about by my ko is a direct plug in
to the receiver with the power source receiver pack pluged into
to the receiver. that is standard wiring for nitro

the older version of KO fet servo are 7.2 volt and it requires a seperate wire to get 7.2volt input.

To my knowledge KO only made one 7.2v servo. I believe it was the 2142. The 2173, "74, "43, "44 are all 6v servos with conventional plugs exactly like the Futabas.

Since you are having 3Pks.. Futaba S9451 (also comes in the standard radio set package) is more than good enough for both 1/10 and 1/8 on road. S9550 always been my first choice for 1/10GP. It is much stronger than it looks.

With HRS, there is no way you can use analog type servos. Don't try it as you'll fry the analog servos with the HRS receiver. So you only can use digital servos only.
With PCM, then you can mix and match any digital or analog servos.
