    Help!!

    Hey gang, I have a scratch build starting that could be simplified by running some 1/16 Summit parts. Here are some questions I haven't found answers for. 1) Will 2.2 wheels clear the knuckles? 2) What size are the ball screws? M4 or what? 3) How close to say 45 degrees do you get on steering? 4)What is the beefiest axle that you guys run?
    Thanks for any help I can get.

    1. Yes, thats's what the stock rims are.
    2. No clue, have to check
    3. Around 35 degrees, maybe a little more.
    4. I just run merv axles, they work pretty great for me! I don't know what the beefiest are that fit.

    Thanks. I'll be needing axles that are longer than Slash 1/10 but shorter than 1/10 Summit. My lhs is open Tuesday, and they have a 1/16 scaler I can put my hands on. Thanks for the input, hopefully someone knows the pillow ball size that screws into the a arm and I will be ordering parts.

    Ok, just borrowed my Dad's calipers and got these measurements: (These probably aren't exact)
    Entire Length: 18.54mm
    Ball Diameter: 7.44mm
    Screw Part Diameter: 2.94mm
    Thread Length: 9mm (about)
    The Pole Part Length: 12.12mm
    Hope this is enough info for you! There might be better (more exact info) out there somewhere.

    Thats great, thank you. M3 will work, I'm just skeptical about the bearings I need to run a 5 mm Slash stub axle. It's a crawler, so hopefully they'll survive with 5-1/2" tall tires. Are the plastic bearing carriers fairly stout or do I go for aluminum pieces instead? Experiences?

    Are you talking about the axle carriers?

    They have been doing fine for me, but I will need to replace them soon (6-7 years old, with a 4 year break in the middle). They make the wheels wiggle around at higher speeds because they are worn quite a bit, I have never tried aluminum ones. I also haven't even looked at my bearings, they might be bushings for all I know. I really need to check them.

    Yes, those. Going on what should be about an 8-10 lb crawler, Bomber to be specific.

    8-10lb!!! I'd go for aluminum carriers at that point. Bombers all the way!

    How long are the axles, or should I ask which rig using this axle format has the longest axles? From inside joint to the outside joint, stretched as long as possible? Inches please.

    I have merv axles on mine, they work well and they aren't much shorter, if at all.

    Thanks for the pics. These won't work on my Bomber, but will work on 2 other projects. All is not lost, I'll use them on 2 scratch builds.

    Here is where one set will end up. No room for drive shafts so its 2wd time.
