    Huge Traxxas Summit OVERKILL

    I am starting my Summit 1/10 build. This is my first hobby grade rc and my first build and need some help. I am looking for some huge wheels and tires . I have some tires i would like to use Interco Super Swamper 40 Series 3.8" TSL/Bogger Scale Tire Part Number Z-T0109 from RC4WD and want to use these wheels Demolisher Universal Beadlock Wheels 14mm, 17mm 23mm Part Number Z-W0137 but not sure if they will fit Summit. I am also dropping a Castle Creation 2028 brushless 780kv motor and Mamba XL2 34v esc . I will be running two 8s lipos. I have ordered the aluminum chassis and motor mount from Kershaw Design so my second problem is i cant find a 32 pitch spur gear with a 8mm center bore to fit this big motor. Thanks for any help

    man you will need diff up grades emediatly with the tires alone ....and the 1/5 scale motor on 8s....its would be recomended to get steel center drive shafts and either lem's aluminum drive shafts or some steel drive shafts...and the 2028 motor i dont think it will fit in the summit cuase of how big it is

    not to cut you down but to acomidaite the power system and tires your going to have to spend alot more money then what you have already

    I have already ordered a motor mount from Kershaw Design that is built for Summit and has the bolt pattern for the Castle 2028. I have a big list of parts to find and order yet I stopped adding up prices around 1600 not counting price of Summit itself . MIP steel center shafts and steel axle shafts are a must since i have destroyed so many with the stock setup . I could live without the tires and wheels for now considering the tires and wheels alone weigh a total of 16 pounds . Which is more than the whole Summit as stock i didn't plan on bashing it or any speed runs. I built a 2ft by 2ft steel trailer that i hook to my kids Summit and was planning to haul my Summit . I just can't believe a 30 dollar pinion gear is holding me up.

    I see LOTS of broken parts in your future... the Summit is near its limits with brushed DeWALT power, let alone a 1/5 scale monstrosity. I am not even sure hardened gears and all aluminum/steel drive line will even hold up.
    Whatever it is I just typed... could be wrong.

    I would gladly pay that to get this build moving again. I dont know what it would cost to have someone special machine one for me but thats my next option unless i can find a spur gear in Mod1 or Mod1.5 that would work on Summit. Those are the only pitch gears that come with 8mm bore that i have seen.

    I think I should clarify... I'm not attempting to discourage, only inform.

    Last time I was on Kershaw's site I remember seeing quite a few pinion options.

    My plan is to buy two steel 5mm bore 32 pitch pinions, one 14 tooth and one 16 tooth and drill them out to 8mm. Then buy a 8mm pinion and a bore reducer from 8mm to 5mm .Place bore reducer into 8mm pinion ,put that and one of my 5mm bore pinions on a bare 5mm motor shaft ,tack weld both pinions together ,remove 5mm shaft and bore reducer from pinions and using a 8mm drill bit drill straight through the 14 and 16 tooth pinions.If i do it right everything should be centered and balanced.From my measurements the 14 tooth pinion wont have much meat left under the teeth. If motor location allows i can flip the 14 tooth pinion so that the grub screw is on the inside up against the motor and the teeth can hang out over the end of motor shaft that way i wont have to drill all the way through the pinion .If that works i can even go down to maybe a 12 tooth or less. At least it sound good in my head for now

    What about shaving down the motor shaft to 5mm? Is that out of the question?

    Could you drill out the appropriate 5mm to 8mm center bore?

    I wouldn't recommend that unless you have the proper machinery to do it... this is coming from someone that has been around machinists for his entire life.

    Just the smallest fraction too big, you have an off center counter weight on the end of your motor.
    Just the smallest fraction out of true, you have an off center counter weight on the end of your motor.

    Not to mention weakening an already thin walled pinion. For that reason alone I would not attempt it even though I do have access to all the proper machinery.

    I hate to point you in a different area, but maybe you'd find more pertinent info on a fifth scale forum? There are probably a lot more guys delving into the realm of monster builds like this!

    What tooth count pinion are you wanting, that has you sticking to mod 1 or 1.5.

    Maxx I have looked into 5th scale trucks for parts and was not able to do much good due to the way the Summit is built.

    I am wanting somewhere around the stock 14 tooth pinion but I need one with a 8mm center bore . The only reason I mention the Mod1 and Mod1.5 is because they are the only pinions I could find with 8 mm center bore but then I would need a new spur gear to match

    Pretty much everything bolted right in. The servos will work but you will need a stronger servo saver spring and saver arm.

    I have that same shell. That is a true 1/5 scale shell and those tires are dwarfing it. I think those tires might look a tad TOO big on the 1/8 summit. Is your Kershaw chassis standard or the 1/5 size.


    Over kill might be the perfect title

    MAN, Use Common Sense.

    Yes it is the standard chassis but a company named Leading Edge Machining may be working on a stretched chassis with 4WS

    What are you doing to the saver to use that torque?
    The stock spring maxes out at around 400.
    Whatever it is I just typed... could be wrong.
