Tower has these Robinson Racing gears in every size so the gearing possibilities are endless. I was wondering about gear ratios... an 86t spur and a 21t pinion make a 4.09:1 gear ratio. Now a 90t spur and 22t pinion are also at 4.09:1. What's the difference if they both have the same ratio? Would there be any difference in speed, torque, or batt life with the larger set of gears vs. the smaller even though they have the same ratio? |

I would guess no difference in performance AT ALL. But clearance may become and issue with a smaller spur gear as your motor gets lower... With my Traxxas Velineon I clearanced the diff as it is a long can. Since I changed from a 18T to a 22T, I have alot more room. |

Check your esc and battery temps, thats the main thing with gearing. I find the stock gearing works best for almost every application, BUT this is great to change them and have some options to play with. |

Its better to have a larger pinion/spur combo if space permits, will have more teeth in contact between the spur & pinion, which will be stronger and smoother. |

Had the Blizzard out again today. I ended up changing the 20t pinion to a 23t and got a little more speed. ![]() Got it up on 1 track! ![]() Donuts! ![]() ![]() Pullin' hard ![]() Still more work to do. I thought about doing a brake upgrade but I dont think it needs it. I will probably add spring seperators but that's about it. This thing handles perfectly. |

Did a little brake mod today. The stock brakes move on a 3mm threaded screw. Not sure why Kyosho didn't think to machine a flat spot in the middle of the screw to allow the brakes to move freely as to not get caught up on the threads but I did. I dont have a lathe so I threw them in my drill press and took a file to them and finished off with some gritty sandpaper.![]() ![]() I then added some Ofna spring separators to allow the disk to move freely. I noticed that even without the brakes on, they would rub the disk while running. ![]() ![]() The brakes now move freely and after making a few more steering adjustments I now have even better control than I had before. Brakes dont go to full lock until I turn the wheel to full lock and I have plenty of brake feel in between. |

After only about 5-6 runs, I noticed some corrosion on my brake parts and chains. Guess I need to thoroughly dry it out after each run and not just let it sit in the tub.![]() ![]() My brake mod was a failure. The screws I filed down to allow the brakes to move smoothly have started to rust making the parts stick and unable to move freely. ![]() To fix this, I'm going to use Titanium screws in hopes they wont corrode. I also ordered some new springs and some adhesive brake pad material for brake mod v.2. For now, I used some gun lubricating oil to clean up the parts. It claims that it penitrates the metal and helps prevent rust. It did clean the parts so I'll run with it. I also noticed that the wheels dont spin freely. There is a small piece of plastic that rubs the inside of the rims so I broke out the Dremmel and took about 60 seconds and filed down the plastic behind all the wheels so now my wheels spin smoothly. ![]() |

Thanks for the update, that sucks about your screw mod but thats what this hobby is all about. Test, trial.... work or fail its fun to experiement. I always stick my blizzard on the passenger side floor and blast the heat to dry off my blizz coming back to the city after use and don't find tons of rust normally. So your right, just dry it off a bit and that should help. |

Thanks for posting. Is free wheel spin good ? What kind of Dremel bit is that I have not seen one like this before.

I can't remember what it's called. Small plastic cut wheel or something. Funny thing is, on the package, there is a picture of it cutting out the lights of an RC truck. |

I did the same thing to make my wheels spin freely. |

Anybody seen one of these? It's the Steel Differential Gear Set Kyosho part #FZW18 It's actually listed as an optional part in the Blizzard Manual. I think it's originally for the FW03 chassis or something. Anyway, I want one for my Blizzard. I might be going with a mild brushless setup many months from now when winter hits. |
