Default Is the Futaba 9551 servo good for touring cars?

hi,

im looking at the new futaba 9551 (which replaces the 9550) and it has the following specs:

torque - 136 oz-in.
speed - 0.12 sec/60

the reason I want these servos for throttle and steering is because I can mount them lower to improve centre of gravity, and they will save a total of about 40grams compared to the current standard size servos i have.

do you guys think these specs are sufficient for touring car racing? (mugen mtx-4). i race on large high speed tracks which worries me the torque is not enough

i prefer only futaba because thats the radio gear i use.

Yes those specs are sufficient, i just those servos in my three cars right now, nt1, v1rrr evo 2, m3, basically for the same reason u explained... weight.

Trust me those servos will do the job plus some, and one more thing futaba`s shit doesn`t go bad.

Futaba S9551 or KO PROPO PDS-2413ICS

I got the old 9550 for steering and the new 9551 for throttle/brake in my TM G4 EVO and i think both servos works grest, strong and reliable.

Can't go wrong with Futaba. I have the 9551 and it's great. Never had a problem and it's almost a year old and I race or practice just about every weekend.

Maybe 9451/9452 is better for nitro car.

I use the futaba S9452 in both throttle and steering very very happy

FYI : Futaba 9451 owners.

If the white plastic 1st gear is boken ( you notice that with noisy screeching sound + rattles sound mixed together ), you can replace the plastic 1st gear with KO Propo Part #35522. Description : 1st metal gear for PS-2174, PDS-2144/2344/2364.



Don't forget to use tamiya ceramic grease to lubricate the gears.


I don't know about 9452 because I don't own it. However, I think they are the same.

I several 9550's and one 9551. The oldest one is 3 years old used for steering and is still alive. The 9551 is a welcomed improvement over the 9550 because of higher torque. Use two of these, one for steering and one for throttle and you can save a lot in dead weight.
