Not picking just trying to understand. From my noob point of view it seems you are taking away a key selling point to this car....I also thought you could unlock and you could make tighter turns....and thought some of the events it costs you to back up and make another turn in....if you could unlock you would have that tighter turning. | |

Im looking at locking mine up as it will further simplifly the rig and less moving parts can be a good thing. also every options a person choose's to do is different for what the driver needs and wants. terrain and type of driving will be different for everyone. for myself once i lock/spool it will feel like every other crawler out there locked up. but my diff servos have started to twicth and im not going to replace them even though i like the option take your line carefully and should be no issue... well maybe challenging. Traxxas makes spool, LEM makes a spool as well. |

I might have to get this spool and try it out. I would def like to get rid of the micro servos and cables. Clean the rig right up. Less moving parts is a good thing. Still like the idea though of having a locker. Anyone have an install video on the spool? I have yet to see how it goes in.

Had 3 servo failures before I switched to spools. Yes it’s a cool feature but only when it works. Mine is a full comp rig so a failure during an event isn’t worth the risk vs reward for me.

I have the Traxxas spools on back order, but shimmed the rear diff during the build of my TRX4 kit to get by until they arrive. Pics and description of the shimming in this thread '66 K-10 Build Thread |

Glitchy servos are usually not the fault of the servo itself...usually....and having 3 of these little guys fail...that is really insane, are the traxxas servos that poor of quality.....still building my kit and now you have me thinking of replacing the little guys with some hitec or other quality servo. If we are getting that much servo chatter perhaps an out of the gate radio/rec upgrade should be done. These little servos don't seem like they do much and there would not be much load on them....and in building the diffs and the 2speed tranny there is just no that much load on them and it seems to be a metal on metal engagement for the gears....I would have liked a metal paw, but price is something....I bet someone makes an upgrade part if there is really so much load on them it is shelling servos....I would think the paw would grenade first. I still really don't understand all these failures....unless the stock electronics are total garbage. Someone please explain this to me while I still have my car in the build phase. |

For the front diff to stay locked. The servo, gears, horn, board, wires, radio, cable, connector, linkage, pawl, mounts, lever. All have to work 100%. Where as with a spool it ends there and the spool has to work that's it. Rather than worry about 12 components possibly failing I and a few others prefer to only risk 1. When you have to dnf a major event due to some trivial tiny component failing you'll understand how irritating it can be. It also removes user error. For example if I was to pass the radio to a 5 year old kid. I don't have to worry about him bumping the buttons all day and getting stuck not having fun. Mini servos in general are so small and vastly weak. It might not seem like much force. But, generally they fail as they are straining and holding position the entire time the truck is operating. The Traxxas servos are super common to fail as well. It's bad enough that savox even prints on their packaging "Fits trx4". I have had so many brands of mini servos that don't last I just equate it the size of the internal parts. Sent from my SM-G930V using Tapatalk | |
