The 9551 is good for the price yes. I certainly wouldn't call it the best on the market though.

What would you suggest is.

I have also really liked the high end KO servos fractionally faster also very accurate and precise but about 10g heavier. I still use them in other cars just not TC.

I prefer the KO one10 for TC. I think it's a little smoother and more precise than the Futaba's. The Futaba BLS551 would be my second choice.

I haven't used any of the new Rsx series so I can't comment. It should be good just a new version of what I have used just a touch lighter. Still 6g heavier than the s9951.

I prefer the s9551 over bls551 the s9551 is a little smoother and more precise.

I currently have a M11x and will most likely upgrade to M12 soon. I've previously had the s9551, KO 2413 and Sanwa sdx801 till i got my current Futabas. If I'm using a BLS551 now and wanted a change then you guys are saying the KO is my only better option? Does no one run the Sanwa srg v2? The KO do look a nice spec.

Any recommendations for 1/12th. I'm looking at futaba s9650 or the Sanwa 94761.

I cant speak for 1/12th but the high end KOs low profile servos are still digital coreless not brushless.

Corless is less powerful and less efficient than brushless but more precise and smoother.

I preffer the feel of coreless over brushless but the BLS551 is a very good servo.

You haven't tried any KO servo and yet you still commented declaring the 9551 the best low profile servo on the market.

You're either in a very special market or forget very quickly. The RSX one-10 is right there at the top (not that top you declared on last page) but the market top end of servos. Yep, it's low profile too, and all aluminium housing. I would say it's probably the best low profile servo on the..... oh, nevermind.

But it's the next one what makes you truly unique.

The BLS 551 is a newer, more refined 9551. You're the only person I heard saying the older version is smoother and more precise (over one with a brushless motor no less).
And I bet you can tell by hand the 6g difference, not only the .03s travel time.

And yes, I have both (and a couple of RSX-one 10 for good measure).

You should read more closely what is written.

9551 is nice but impossible to find gear sets for. Futaba will replace individual gears on an order basis but stopped shipping the full gear sets a while ago.

this might be handy.

Having a quick look at the tests/data for the two servos I find the non linearity graph is not consistent with the findings about the accuracy. The linearity graph for the BLS551 is closer to expected values than the 9551 and both display the highest non linearity at -45deg (whatever that means?). The rest of the curve is way closer for the BLS than the 9551, so I am not sure how the accuracy claim is supported (the accuracy data is collected with 2kg load, I understand that, not sure what is the load for the non linearity test). If the load is the same, then the two results are not consistent hence further refinement of the test is needed, and more data collected (more servos tested). This is true anyway, otherwise what you've got is a single data point (one servo of each tested) which may or may not be representative, but in any case statistically irrelevant.

Back to the OP question, instead of all the useless arguing...

For your budget if you want new, I would suggest looking at Savox servos. They fit your budget and will get the job done. You could also probably find a used servo like the Futaba BLS551 or S9551 here on RCtech in your price range.
