Have you tried the factory horn that came with the high torque servo saver?

I use this servo saver exclusively on my Tamiya cars and what I do is make my own extensions to the high torque servo saver horn. I can take some pictures later, but I have no issue with play, horn swivel length, or it loosening.

BTW, do you have the round cover at the very top of the servo saver? You need that in order for the thing to work properly. 3rd one on the right, second row below:

Wait, so there is a 2nd gen SabreFD Mini? :confused: And you could tell all these things by just looking at the car? :lol: wow! ;) The kit ball diff is very similar to the M05 ball diff; I have no issue with the M05 ball diff so I did not think too much of it?

Thanks for the tips. I spent about $200 on spare parts for this chassis and some hopup diff gear set is in there along with several pairs of universals. Will see how the factory pieces hold up. I only run silver can with TBLE02S on all my M-chassis including this Sabre, so I think I should be okay.

The plastic arms are okay in some cases, but the alloy arms have some play. You are correct in that the arm seems to be narrow cause the springs have a gap to the stops on the arms.

I guess another simple solution might be to go back to the tock arms like you're using.

My bad, I initially thought you had the TC Sabre FD, not the mini. The drivetrain is the same and the weight of the car not much lower, so I assumed the advice (whatever it's worth ;-) still applied to your case and didn't bother editing my post. I've ran Photons for quite a bit of time so I'm acquainted with the TOP alloy; it is "rather" soft and the dogbones get chewed up really fast, even with slow motors. Plus, FD cars tend to like spools or firm diffs and it makes the problem worse... common knowledge really.

HTH- Have fun !

Yes the play is on the horn side, the rings are nice and snug on that side. I think the Savox is 25t and from memory it's the Futaba attachment I'm using

I'm now wondering if screwing it down too tight might 'open up' the stop....?

Curious that you would want to spend time to fix something that is poorly designed and executed rather than using something that works. However, I understand cause the Kimbrough is just plain ugly. Kept me from using them cause the Tamiya unit just looks "right".

Unless they changed it since I last used one, this is the problem. If you'll check how the springs fit the servo arm, you will see that there is a large gap between the end of the spring and the notch they are supposed to fit on the arm. If there is any gap at all, there will be play around center. At least one of the springs have to fit with no gap to eliminate this sloppiness around center.

To be truthful, as soon as I figured out the problem I realized the "fix" would be very difficult and probably beyond my skill set. The fix of course is to eliminate that gap between the end of the springs and the servo arm. The fix I opted for was to toss out the servo saver and that beautiful, expensive, blue alloy arm and use a Kimbrough. I will admit to grinding and reshaping the Kimbrough to beautify it a bit cause they sure are ugly and "cheap" looking.

Granpa, Boons - Here are pictures of the horn extensions I made for my M03. Works great for me. :D

Basically I just cut off the tip of the kit servo saver, trimmed, and attached it to the high torque servo saver horn.
No clearance issues with the chassis.

I couldn't get a good shot with my phone, but here they are for reference:

Hi Granpa, good to hear from you.

I've been on and off this page, and racing following major shoulder surgery!

I'm now interested in the Kimborough. I use one on my bashing 50mph car with no issues. A few guys at the club have used them on M03's and managed to break them. Any breakage issues on the 5? Which one should I go for on the 5? I see they are KP this and that.

Cheers!
