  • Free Flyslot – help needed

    Hey everyone – so my buddy at work got out of slotcars and gave me a Flyslot 917k (Vic Elford). He said it didn’t run from day one and was ready to toss it. I took it and it looks like the plastic pinion gear is cracked – so the gears don’t mesh right. It appears to be a 2mm 11T (from what I’ve researched) – would any 2mm 11T sidewinder pinion gear fit? Since the replacement most likely would be non-plastic would I need to swap out the spur gear as well (which is plastic and 36T I think)? Recommendations?

    I don’t have a pinion press/puller – but looks like Ninco makes one? I’d like to try this – the car is pretty nice looking and I don’t own any Fly cars (other than this one) - just don't want to spend more than the car is worth.
    Is this a pretty straight forward task – tips for a first timer?

    Thanks!!

    very common for fly. the ninco press works fine for putting them on. not so good at taking them off.. we have a fly class and what most of the guys do is toss the fly axiles and wheels and go slot it on both ends. 10 /36 is stock gearing and 2.0 mm shaft sidewinder pinon

      I own a Ninco puller and other than it being a bit fiddly in both pulling off and pressing on I feel it is fine as a first tool. Of course the very nice Slot.it puller is way better but then they are also pretty expensive @ north of $60.

      I have several Fly Classics, including something like 6 (how embarrassing....) Porsche 917's. My personal preference for pinion is an 11 tooth Slot.it SIPS11 which works very well with the stock spur gear. Note that you HAVE to use the 6.5mm diameter Sidewinder gear. As for replacing the rear axle with Slot.it parts: while this is clearly a better solution, it does cost a fair few dollars. For normal club racing I personally am quite happy with stock axles (complete with plastic spur and plastic wheels) on the Fly Classics. If you glue and true the tyres properly it works fine: just make sure you glue the bushings in place and keep them well lubricated. With a little bit of TLC I find the stock setup perfectly adequate for all but the most demanding racing situations.

      Enjoy your pretty new 917: as shown by how many I have I obviously love them!

        Yep, had this same problem on a few of my first Fly cars. Couldn't understand such terrible quality control - seems to me checking that the rear axle turns would be the least thing to do after assembly. Luckily I had a bunch of replacement pinions acquired from other cars over the years to do a swap, keeping everything else stock. All my Fly cars run well now with this simple fix.

        Never had this problem with GB Track cars (also Fly cars) so perhaps a single assembly person didn't know what they were doing and covered their errors, or a large shipment of pinions were defective.

        If needed you could contact SCC or Coverleaf and ask for help getting replacement pinions to fit the motor shaft and you'd be all set without a major investment.

          My tip? Invest in a good puller/press now. That is if you are in this hobby for the long haul.

          I know....they have a pricetag on them no doubt, but they pay it back to you over time...

          Otherwise, yeah, grab the NINCO.

              Or if you don't want to spend much and you just want to get the car running, an 11 tooth Scaley plastic pinion will get your car mobile until you go for the dearer stuff.

                Very common for Fly cars to have split plastic pinions. Bet that out of about 10-12 Flys with plastic pinions, only 2 or 3 were good. It's almost automatic to pull the pinions and put a brass one in it's place.

                Like others have said, spend the money on either a Slot-it press/puller (have one, recommended) or a Slotting Plus press/puller.

                  Stock Fly pinion is 11 tooth, 6.5 mm diameter, 2mm shaft hole. Lots of good advice here. A pinion press and puller are a worthwhile investment.

                    I searched for a puller on the websites attached here and saw a "Slot.it Professional Mini Pinion Puller" on LEB. Would that be the thing to get, or is there something else out there that would be better?

                      The SISP31b is a puller only. You won't be able to press pinions on with it. The one you want is the SITL01 Slot.It Professional Pinion Extractor Press. LEB has it for $58.99.

                        The combination tools that are available tend to be costly and some of those can strip out after a little use. I prefer to use a separate puller and press. Good gear pullers are fairly cheap, but I can't think of a good gear press for 1/32nd gears. I use one that I made myself. Using an improvised method could result in bending a motor shaft or damaging a gear. If you just put the gear on a hard surface, line up the motor shaft and hammer on the other end of the shaft you can get the process started. It would be better to use a C clamp. In both cases once the gear was flush with the end of the motor shaft you would need to use something as a spacer before you could finish pressing. A dedicated wheel press would have a recess for the end of the motor shaft.
                        Look at this article, there is a list of tools at the end. https://drive.google.com/file/d/0BzL...ew?usp=sharing

                          Lots of great advice - thanks so much!! I ordered the Slot.it extractor/press. I also got a Fly Ferrari 512S as part of this "deal" - it runs but will most likely swap out that pinion (inline) as well. Figured I get the recommended tool and have at it. Also ordered some quick slicks to try as I'm going to remove the magnets.

                          Cheers!!

                            Fly/GB Track/FlySlot/SRC cars are all very good looking slot cars. Running them is a whole other story. Depending on many factors it can take anywhere from a new pinion up to a complete replacement of the chassis and all running gear in order to get a well handling / running car. Hudy puller, Slot.it press - best combination in my opinion.

                              I’ve been using the same Ninco puller for over two years. Never had an issue pulling gears, or putting gears on
