My servo saver mod for Cougar
Thought I show you what I did tonight. It is a Tamiya Hi torque servosaver that I used together with the tip of a standard Schumacher servo arm to achieve the right length. Did NOT dremel anything on the bulk above to make this work. I did all the dremeling on the saver itself. I had to move the servo back/down to clear the bulk even more and get the right angle as before since the tamiya saver has got a different offset than standard servo arm. This works with low profile servos such as mine but dont know with standard sized servos.
Let the picks speak for them selves. Not good looking with filed alloy but it is more function than looks this mod. |

I love the work, but I've had 3 full race days(12 races) without a problem. Nice to see the creativity but I don't think its needed.....yet

I did it just in case. I would kill myself if I went to a meeting and DNF cus of a striped servo arm.
I`v got another problem anyway...those LRP speedos. |

a servo saver will take all the positive feeling out of your steering,

ive made one very similar using a kimborough and cougar horn, works a treat, no more slipping the horn on the spline. that as happened to me a couple of times. but apparently the servo im using is a cirrus which as a 25 tooth spline is around 0.20 of a millimetre smaller than other servos on the spline. also the schmacher saver with the metal spring works, just need to bend the arm back a little so its 90degrees with the chassis and lightly file the top of the saver

something like this would of probably saved my £43 but i reckon it is only needed on a small low profile servo, the gears are smaller right?

well i stripped the plastic sacrificial gear in my KO 2123 today in the cougar, so i would say full size servos also need it!

I think the Tamiya saver is the only one up for the job. Its rather tough and does not take away that nice feeling that more soft savers can do. If it is enough in a TRF511, it should be ok in a Cougar.

I spoke to Phil Booth about this very thing, and he told me the standard servo horns are a VERY tight fit. This means people often seem to put one on that actually too loose.
Don't expect to be able to push it on then put the screw in, you'll need to use the screw to pull it onto the splines. Once it's fitted on that tightly they don't slip. Not had a problem since doing it that way. |

i have the plastic version of this tamiya saver. IT has 3 spring tensions, should be worthy piece to modify if i used its hard spring? Not sure im up to dumping large coin on an overpriced tamiya part. Bad enough i would consider adding one to my car let alone pay for it! LOL

I have the MI4 servo saver which fit into the car perfectly without any mod.
It comes with two kind of spings. Ref is U2882... regards |

I've found the stock schumacher horns fine if your using a Futaba servo, but the Hitech horns are useless as there splines are not there and strip out instantly.
I've blown up a couple of S9551's in the Schumacher, one in my Cougar and the other in the Catsx.. and the damage was done to the first big gear, taking one tooth off completely. |

well we have be running the std servo horn on are cougar, using a savox servo and its been there for nearly twelve months now no problems and defiantly no girly servo saver in there
just buy a good servo instead of cheap one and then have to get a servo saver

Are the dimensions of the U2882 the same as the stock horn? Although i agree using a good servo should not need a servo saver... The other issue is the actual steering rack its self. in a hard hit the servo may not break but the rack and associated parts might or simply get sloppy over time.where the saver could prevent all this.. |
