| Ryft servo/save question
Hey folks, My wife recently won a new Ryft at the Badlands Axialfest raffle. I'm familiar with many of the issues people have been having with theirs. So far though (keeping fingers crossed) the only thing that has broken is a rod end (due to a collision) and the stock servo saver wasted pretty quick. I ordered the Axial 23T metal servo arm to replace it. But I was told that the stock servo will likely fail next. Is there a 23T servo saver that isn't junk that you guys can recommend? And assuming the steering servo dies, what's a beefy replacement? Thanks, NP |

First, cancel order for that servo horn (if you can), or return it as soon as you get it (if you cannot cancel the order). Next, get yourself a higher quality, stronger, faster servo. RTR servos (from most companies) are notorious for being underpowered, and too slow. Then, either get the Losi LMT servo saver horn...or, better yet, get the machined aluminum LMT Servo saver horn from Hot Racing. ~ More peace, love, and kindness would make the world a much better place |

I lightly bumped a rock with my RTR servo (with aluminum horn) and it broke the gears inside. Definitely plan on replacing that servo soon.

| Re: Ryft servo/save question The Hot Racing servo saver is not the one to get (it is possibly even a downgrade from the stock LMT servo saver), the LMT servo saver made by Treal is the way to go.

I dropped a Reefs 444 in my Ryft. They are a 25T spline. For Servo Savers there are a few options. Vitavon has one coming. Treal has one but out of stock (one green one for a Losi LMT on Amazon yesterday). ServoAF has a drag link stle servo saver, so it will go with any servo and decent servo arm. Then Vanquish is making stuff. Maybe they will bring one to market too. I will be patiently waiting for the ServoAF unit to become available. They say first week of July, so any time. Update. I swapped the 444 to a Reefs 555 I had in my SSD TK rig. Put the 444 in that. Last edited by Timmahh; 07-06-2021 at 01:48 PM. |

I took apart the stock servo saver. With the exception of the plastic disk that makes contact with the springs (it should have been metal), it's actually a pretty stout piece. I just glued it back together with liberal amounts of gap filling CA and going to run it that way and see what happens. The Treal saver looks really nice but it's pricey.

Servo AF Drag link Saver is 50. I suspect the Vitavon setup will be in the 50 pennies range as well. Last edited by Timmahh; 07-01-2021 at 06:11 PM. | |

I know I can't yet do a "permanent" final assembly, since I still have to take care of the interior...but, just to truly test the HR LMT servo saver, as well as the 3D printed 2-speed shifter that PowerHobby did for me, I might as well do a "temporary" final assembly. At least it would be operational...plus, I'd be able to work on the ESC programming. ~ More peace, love, and kindness would make the world a much better place |

Don't bother with the HR servo saver. I got one and it's complete junk. The actual horn itself is nicely machined aluminum with a circular spring but the adapter for different servos are soft plastic rubbish. The don't fit well at all on either the servo or the horn and they break and deform trying to get them off after being pressed on. They're also not marked so you either have to count the teeth or just hope you have the right one. I don't know why companies insist on using cheap plastic inserts on these so called heavy duty servo savers. I'd gladly pay $5 more for all metal. Should've just got the LMT or Treal. |

The problem with that one is the hex that fits into the servo arm part is not great so you get slop in your steering off the bat. Then the harder hex on the servo spine tube starts to strip out the softer aluminum hole in the servo arm like using a cheap, ill-fitting driver in a stainless screw. | |

Oh. The one I'm talking about is not that one. It's this one: https://hot-racing.com/?partnumber=SHS88H;c=434 Quote:

The LMT HR type is pretty much identical to the Treal LMT Servo saver which is priced at 38. | |

You cóuld go for a ‘damper’ on a solid servo horn, i.e. Take an old, not too thick, shock, fix a very hard spring above, and one below the piston, fill with the thickest shock oil You got ( I used Losi 90 hardness) I also filled the space left under the lower spring inside with some thick spacers to get the right shaft length needed, et voilà, instant servosaving. And as a bonus, really tight steering with the looks of a hydraulic ram. After busting the original, plùs two rather expensive Losi LMT savers, I went for the ‘shock-solution’ and haven’t broken anyting ( yet) after about 4 or 5 runs.. kindof a record for me.

Update II. I been using the ServoAF DragSaver (my name) drag link setup wtih the KNK hd 25T horn with fine success. the new springs (from my understanding) on the Drag Saver are heavier then original ones. So far its been very reliable and not compressing except under hard hits as it should. I also have the Treal Servo Saver for the LMT. But they are also making a Ryft Version now, that should be out any time. It looks like the horn part of the Ryft piece will be lower on the spring perch tucking the horn closer to the servo giving more clearance than the LMT part is. I'm going to put the LMT saver on my RedCat Gen8 AXE rig. It has a ridiculous angle on steering drag link. So I have an SSD bent drag link coming for it. That with the Treal LMT servo saver should give a bit better steering geometry to the AXE. Treal also asked about new items for the Ryft. I hit them on a new Diff Design and HD Diff Gears. Vitavon is also cutting new diff gears. Hopefully they address the ring gear ridge. Considering they are making a R/P already, Maybe I should speak with Edward and see if he can cut one with a thicker shoulder on it instead of the ridge. |
