  1. Interesting point, but I am not sure if there is a "chicken and egg" problem here.

    Racers looking for a scale-type racing class don't race because current classes aren't geared to them. Hardcore racers don't pay attention to what would win in a class that doesn't exist.

    As an aside, one reason certain 1:1 racing organizations have so many mid-season rule changes is to keep the racing competitive. 

    Similarly, in 1:1 racing, some of the rules that are intended to prevent "buying" wins have the opposite effect. For example, it costs a lot more, in terms of time, effort, specialized expertise, and cash, to modify a set of junkyard small block chevy cylinder heads for dirt track racing, than it does to buy and rework a set of 23° aftermarket heads to get comparable flow numbers.

  2. My experience is limited, but get the puppy used to spending the night in his or her crate.

    Do not come get the puppy when it cries. It will otherwise learn that crying will get it out of the crate.

    Training is easiest and most effective in a low-distraction environment. Usually that means home. Once the dog has mastered a command at home, move to a slightly more distracting environment, such as the yard.

    Also, I taught my dog (a very large and dominant male pit bull terrier)  that nothing is free. He'd have a nice meal, but he'd only get to eat after I said he could eat, and he'd have to sit and wait first.

    It got to the point where I could leave a raw beef liver in his bowl and I'd tell him to sit, right in front of it, I'd walk out of the room, and he knew not to touch it until I came back and told him he could eat.

    As someone said, first people eat, then dogs eat. 

    Find out what motivates your dog (food, praise, toys, bones, whatever) and use that as a training reward.

    Is it anything to do with the drive shafts clicking in the drive joint slots ? , are the rear arms hanging too low ? This used to be a problem on the old Fox with the original shafts . Tamiya sent out a note that the rear arms should be raised . The original Wild One rear arms were also modified by Tamiya to give more lift to the arm stops

    Does the fact that there is no clicking when I rotate the wheels by hand mean anything here?

    Not trying to sound snarky.


  4. I own only one Tamiya, a Fox. I like the car, but I hate having to constantly fool with the gearbox/transaxle/whatever you want to call it).

    Recently, I bought a complete Novafox kit, just so that I could finally have a reliable transmission that didn't need attention all the time. Built the transmission with Kyosho 15K diff grease (not fluid), all seemed to go together smoothly, all new parts from the kit. I followed the manual, although Lord knows I have rebuilt Fox transmissions often enough.

    Well, this transmission also clicks on hard acceleration. I tried everything I could think of, tightened and loosened wheel nuts, tried a smaller pinion gear, adjusted the play between pinion and spur gears, tried the stock silvercan motor, tried everything short of tearing down the brand new transaxle.

    Some things mitigate the noise, but it is still there. Motor is a Traxxas Titan brushed, esc a HW 1060, so nothing crazy here. Pinion gear is usually 18T. With that setup, the car is a wheelieing fool. 

    Can anyone tell me what I might be doing wrong here?!?! I've built other Tamiya and lots of Kyosho trannies and I don't have this problem. Just on the Fox.

       

  5. When my son was around three, I got him a cheap r/c crawler. It was slow and it could drive over obstacles, which is fun when you are small.

    Afterwards, he got an Associated RC28. Much faster and very tough. Because of its propensity to do donuts, my son dubbed it "Donut".

    When he was six, he got a Tamiya Sand Dragon, mainly because it was something he could help build and it was about all that was available. He named it "Cricket".

  6. Told the little man that we'd go to the buggy track today. Well, racing cancelled at the last minute.

    So we ran the Javelins around the back yard for a bit, trying out different things. Noticed that one Javelin had broken its rear tire loose from the wheel. Great.

    On closer inspection, the universal joint had come loose from the drive. Wonderful. And that happened because  the rear shock was broken. O joy.

    Took the buggy into the basement and rebuilt the recalcitrant shock. I was going to do the other for good measure (also because I didn't have factory Kyosho o-rings for the rebuild) but decided not to.

    Perhaps this was laziness, but it didn't seem wise to rebuild a working, leak-free shock. Also, because rebuilding shocks is hard enough without a little person to "help". 

    Re-assembled the universal joint and re-glued the tire

    Any more cars after the Turbo Scorpion run 2.2" ?, or do Kyosho agree with me, and think they look awful on a vintage.....🙄

    Agreed. I have some 2.2 wheels for an Optima and another set for an Ultima.

    They look hideous. With most tires, they make my buggies look like truggies. Or maybe monster trucks.

    With low-profile tires, they make my buggies look like they are rollin' on dubs.

  8. I only have five buggies and my son has one.

    All are in running condition, but I only rarely run some of them, the ones that are original vintage cars or that I spent an inordinate amount of time to make look nice.

    Also, I have a habit of accumulating massive spares stockpiles and I am sort of OCD about wanting to fix anything broken, right away.


  9. Nowadays, brushless motors and Lipo batteries make it easy to make any car achieve top speeds that were unimaginable when I was a kid.

    Whether the car will handle at that speed or even be controllable, is another question.


  10. Something occurred to me the other day:

    One thing that can be said for vintage Tamiya cars is that they generally resemble cars and buggies of their day. You can easily imagine a car that looks much like a Frog, except instead of tearing up the local baseball diamond, it's running stages in the desert.

    When we build them, we try to make them look realistic, or at least box art. Even the much-praised Tamiya box art could easily be a depiction of a 1-1 buggy.

    All the time, we see people here building the buggy that they wished they had when they were kids, or even restoring their childhood friend, after spending years in a box in Mom's attic.

    A modern racing buggy, is very different. It doesn't look much like any full-size vehicle, past or present, nor is it supposed to. In many cases, it was made to run on carpet or astroturf. I don't think many full-size vehicles were made to race in that environment.

    These cars were built for one thing - a very specialized (and impractical) form of racing, and the racers themselves are quite competitive and not sentimental. Even if the hobby is something we associate with teenage boys, the guys racing modern buggies and cars aren't really playing.

  11. Further assuming that your gear mesh is okay (which is probably the case if your motor isn't hot), try a taller pinion gear (assuming it will fit) and see how it works.

    After you start doing it a few times, swapping out pinion gears will seem like no big deal.


  12. What motor and Electronic Speed Control do you have? Does the motor get hot when you run the buggy?

    What pinion gear do you have in it? (The pinion gear is the gear that is attached to the motor shaft.) Assuming everything is working, you may try a numerically larger pinion gear. 


  13. My father was a professional pilot, licensed to fly every make and model of fixed-wing aircraft known to western man. He also held an ATP, instrument, aerobatic instructor, etc. licenses. He also had been a professional scuba diver.

    The man had skills that I would have committed terrible crimes to have had, and I never understood what was so fascinating about weekend TV. I would have spent every cent and waking moment, doing inverted flat spins in a Pitts Special.

    Yet he had no more interest in flying than a bus driver has in bus trips.
