100% agreed.... I don't like super fast servos either. It's makes the plane too twitchy for me. Though I don't really care for the 985s after going to the 7985s

My fingers don't usually move as fast as needed for this one.

super fast servos (excluding the new brushless) tend to use more juice than the slower ones. besides anything faster than .15 is faster than you can react anyways.

Not exactly. When you move the stick from center to corner...you can DO that very fast.....for example a hard tumble. With fast servos, the plane reacts "crisp"....with slow servos, it feels like a slug. Just one example.

In my opinion...faster servos are ALWAYS better and worth the money, the planes just FEEL better. I don't want my planes to "mask" poor inputs or make my flying "smoother" just by slowly reacting...I expect them to move NOW when I give an input.

Ever since I overpowered the 104 ailerons with 3 7955's per wing...it felt SO good with full power and plenty of speed....then my 74 got fast servos....and so on...I'll never go back.

I had sped up my 7985s on my 71 by upping the voltage to 7+ volts. They were to fast for me to keep the plane smooth on high rates. I backed them down to 6.3 volts and they are still very crisp but my plane feels smoother. I upped the power on the 7955s in the 89 and I am really liking it. That plane is smooth no matter what I do to it

I agree totally, I run 7955's and 54's on 7.4 and love them compared to slow servos, I also like having more torque than minimum recommended. that said, even though I DID notice a difference between my ultra fast servos compared to old slower ones, I don't think that many people will notice .04 seconds in transit since the average human reaction time is .25 seconds. That said I havent tried some of the ULTRA fast HV's from savox, futaba or JR yet even though I was eyeing the savox brushless .06 second servos for the ailerons!

Totally agree - faster is way better
You can really feel the difference
Expo softens the centers
Love the HS 7940 TG's on my 71 Slick and 72 Extra (0.06 sec speeds)

Slow servos make my flying look smoother, but they don't feel as connected. Fast servos perfom tumbles, pop tops, etc, much better IMO.

Reaction time may only be .25 seconds, but I like most of my flying to be planned out ahead of time by at least one maneuver. The idea is to not have to 'react' to the plane at all. It should only be doing what you planned on it doing. Under these circumstances reaction time doesn't even come into play and fast servos become very useful.

7955's aren't fast though... on 6.0 volt the spec says .15 sec/60 degrees.
I actually think 7955's are a good speed and like them. By fast I mean things that are in the .08 or quicker range. I ran some Align 610/Savox 1258's on my 70" Slick at 6.5 volts. They are rated .08 sec at 6 volt, so they were that or faster. It took some getting used to when I was used to 985's, which are rated at .13 sec/60 degrees. Timing on a few things was off and it was different.
On larger planes I would expect the faster the better. On 70" planes they react so much quicker than 50 or 100cc planes anyways that super fast servos will definitely be noticeable. Once I got used to them it was better, but still the plane showed every sloppy move I made. I don't have nearly the thumbs that you do Bivens! I think that for me servos in the .10-.12 range are probably my ideal.
