  1. An absolutely stupid question, and I apologize for it. How do I change my profile picture?

    I did a pretty good search on the site and couldn't find an answer. I tried to link to an image on an image hosting site and I would get an error saying that my image exceeded the size allotment of 1.024kb, It's a link to an image that's maybe 20 characters long - I also tried to drag and drop an image and was told that the image exceeded the allowable size of 0.00097MB. These are both CRAZY small sizes... what am I missing?

    Thanks for the help and sorry to bother with such an idiot question.

  2. Hi Everyone - as we all know Photobucket's free image sharing has gone down the drain and with it, all of the links to our images of our cars, our builds, etc. It really annoyed me that I went through all that time and effort (and dealt with all their horrible advertising) to get images up onto their site that I had thought out onto this site and others. Well, problem solved. I updated all my images. For those of you that fancy a look at my ANCIENT posts, feel free, for those who don't no biggie. I just feel better knowing that they're fixed. :-)

  3. Have been in a bit of a holding pattern with this for a bit as there are still questions to be answered about the transmission as well as trying to locate a decent windshield/glass for the 3B. Additionally, the more I think about it, the staggering of the front and rear wheels (which are now narrower) will likely be a problem stability-wise; I'm pretty sure it will make a tall vehicle more tippy than it already is. I have seen some "axle lengtheners" on cheesebay but they don't look like they'd do the trick. Anyone have knowledge about these?

    So that's where this project is at the moment, not going any place, but not going forward either. :-\

  4. 47. Getting harder and harder to justify buying kits to the wife every year... that's why I do my best not to tell her! I no longer have the first car I ever owned, but i have the 2nd - a very well worn Grasshopper from 1985!

  5. I still have to get them - today being Valentine's Day though, the Mrs. probably wouldn't be too pleased if I went to the basement to play with my r/c, lol. The pinion gear is really small though... 99% sure that's where the issue is.

    Could you give me the tooth count and outer diameter of all the gears that way I could try to figure out what kind of pitch or mod each gear has.

    My gues sofar is that the diff gear has 42 pitch and the motor pinion 48. (V2 has 32 pitch)




    Took the trans apart again last night to try to figure out why the gear teeth were grinding/locking up on the Triple B. Got a tooth count on the pinion gear (18), the idler gear (32), and the diff has 60 teeth. I'm not sure, but something seems wrong with the diff. When the trans is fully assembled and one wheel is engaged, the differential is very stiff, it takes some effort to move it. While it takes effort, it does move freely, just stiffly. When both wheels are engaged, rotating forward or reverse the transmission seizes up and won't rotate the wheels. I think I have a spare set of original transmission gears that I might put in to see how they feel.

    Does anyone have experience with these ball diffs who can tell me what they're like or how they should feel?


  7. I'm not sure what causes the failure of the stock gears, I would guess cheap materials and weak design. Although you'd figure with so few moving parts in the transmission that would be a strength, not a weakness. There is noticeable play in the transmission after it's assembled. No bueno.

  8. Alright, I got my 3-d printed axle sleeves today! I was very lucky and had all of my measurements spot on except for one - the inner diameter of the sleeve itself. It should have been at least a half mm bigger than I designed it. No biggie, I just reamed it out to size and it fits fine.

    Using several bushings, I made an impromptu spacer for one of the front wheels to see how it looked and noticed that the front wheel is closer to the body than it ought to be. Pretty sure this is due to the offset of the wheels. Does it matter overly much?





    You can see the offset difference below.

  9. I designed a Big Bear rear axle sleeve that fits over the axle's hex nut, acts as a 40mm spacer and has a flange and a hex head to mount Tamiya's Suzuki Jimny wheels to. Keeping my fingers crossed that this will work! But knowing me, I got mt measurements wrong someplace...

  10. Three out of five packages ordered arrived today, the other two due by Friday I think. Two sets of Tamiya monster truck tires - Lunchbox wheels and tires as well as Suzuki Jimny wheels and tires. Also arrived are the two pieces I had 3-d printed, a new bumper for the Big Bear and the front body mount. The body mount will work perfect, not sure how I feel about the bumper... seems a little weak and a bit ridgy?
