Size comparison with a regular Bigfoot Stampede. Have an idea on a paint scheme but down the road a bit yet. Obviously building on a truggy theme.

    Having issues with the Proline Prospline H/D cvd’s. They are not long enough for the Protrac 4x4 arms oddly enough. Im reading the MIP X-duty cvd’s are what is needed. Notice the yellow tape on them I put on at about 10mm so you can see there’s maybe 6-7mm of the splined shaft going into the female portion. I’m planning on limiting the shocks so arms are going to be a lot closer to level giving me closer to 8-9 mm contact but I don’t think that would be enough. Shocks are about 125 mm long I’m really not sure how much to limit them yet, 7-10mm?? I just don’t want full droop in the air.

    Another size comparison just chassis’s with a pretty stock Stampede with the exception of Proline Protrac a-arms front and rear

    Basically the rear cvds is whats gonna hold things up a bit. Other than that I just need front steering links that Im betting would work from a T-Maxx or Revo lengthwise and a hd servo savor. I bought a cheapy metal gear 277oz of tourque servo for the steering. Planning on using a Hobby Wing WP-SC8 esc and a Tenshock SC401 4600 kv 550 can (4 pole?) motor on 2 cell lipo. Have read this motor really draws amps so Im not gonna mess around with anything under a 300 amp battery. I do have a older 5900 60c that balances up perfectly still.

    Tried lots of combinations of arms and rims trying to get as wide as possible and hopefully hold up too the forces of a much bigger wheel. Have some dimensions on a-arms I will post down the road along with w/b dimensions.

    Started this project along with 2 others early last year. I have a 11 year old daughter and a 7 year old son that I’m gonna try to get hooked on rc cars like I am and knew the Traxxas Stampede is the perfect platform to start with.

    So this is my daughters and I’ll admit this one snowballed out of control fast and I completely overbuilt it. Expense wise I probably would have been better off buying a Proline Pro M/T. Think I figured if I didn’t end up liking the 1/8 scaler this one would be mine. Anyways it should be extremely durable.

    I did stumble on the chassis, shock towers, bulkhead and Proline shocks on a project someone was selling on eBay. Two of the shocks show some wear on the shafts but other than that I dont think the rest of it was even run till we did. Keeping the speed down for now by using a Trinity D3.5 17.5 and a Novak GTB esc. Other than non waterproof Its perfect for her. I suppose its close in speed to a stock XL5/550 setup. Probably less tourque though so gets on the warm side when doing long laps around the yard. Really want to get a Castle SV3 3800kv system but not sure when she will be ready for that. My buddy has that for his boy in a Stampede with Proline Trencher tires and its the perfect setup. Not sure how fast, got to be 40 MPH easy and absolutely wears out the wheely bar while staying nice and cool up and down the street or around the yard.

    Finally on this one with the Protrac A-arms and front offset wheels on all four corners (most offset/widest) this thing is so stable. Tough to roll over. I’m gonna throw in a 4000kv Hobbywing motor I have and test this out at higher speeds soon.

    This is my boys and honestly it might be my favorite. For whatever my opinion matters I think these are the best looking Stampedes ever. $199 dollar RTR (from Tower Hobbies) with free shipping to start is fantastic. I installed Proline Protrac Slash A-arms, Traxxas turnbuckles, front offset wheels on all four corners, bearings in hub carriers (transmission has bearings and metal gears already) and a Traxxas wheely bar. Biggest downside so far is the extra set of front wheels I ordered don’t seem to have foams in them but haven’t really noticed that when driving it. I’m running them up front now and wondering if it will be noticeably when on the rear. Since he’s only 7 so far he has just run it in training mode. The stock electronics and even battery is fine for now. When he graduates to full speed we will switch to a lipo battery.

    So far we haven’t broken anything in maybe a half dozen runs so far. The kids are able to run around and not plow into each other or other stationary objects and we are working some smallish ramps in now. I’m always on the lookout for a good dirt/ off-road place to run but haven’t really found a great place yet. I have been running my pretty close to stock Bounty Hunter Wheely King around with them and it’s been great so far.

    So all of our Stampedes have been widened for a couple reasons. Stability and ability to rotate wheels. One of the few complaints I have for Traxxas is why have different offsets on the wheels front to rear? It bugs the crap out of me not being able to rotate the tires and eventually you are running around on slicks on the rear then when you replace them you usually end up with a combination of new and beat up wheels or a box full of front wheels. In my eyes the extra width is a bonus of getting the same offset. Anyways the following posts will be various dimensions, part numbers, and combinations that get the job done.

    Initially I was very surprised to see the Stampede rear arms longer than the Slash. Also notice the Protrac arms for the Slash are the same length as the Stampede but has toe angle built in. The Proline 4x4 rear are the longest bye far and have no toe angle. I don’t have the RPM offset compensating arms on here and am a little confused on them. If anyone knows are there 2 different a-arms? Slash and Stampede ones or are they just for the Slash?

    Ok here is some dimensions. I only have a front and rear set of the Stampede monster truck wheels. My other set are all front offset ( the widest).
    This is a stock setup. Right around 13 inches/330mm wide front and rear.
    E89475A3-C8D6-4F5D-83A6-4C2743047682.jpg 72402305-4353-44BC-A0BC-98C6B91F984D.jpg


    This is RPM long fronts #70662 and RPM Stampede rears #80182 (black color). #TRA 3745 (59mm front turnbuckle #TRA 3743 (49mm rear). You have to reverse the wheels. Front offset on rear and rear offset on front. You have to run the 59mm fronts all the way in. Just under 14 in/355 mm in rear and 13.5 in/ 343 mm in front. There are not any steering links on the truck so they could be toed in a little. Even with that just over a quarter inch narrower in front. Would be even wider in rear if toe was added. A little narrower than my other two mainly because of rear toe but remember how much arm is in that front wheel. Should be a very good performer but I was looking for equal offset on all four wheels.

    This is Proline 6062-02 rear, 6062-01 front, #TRA 3643 front and rear camber links, #TRA2338 94mm turnbuckle with Traxxas short ends for steering links. Think they came with them. #TRA3665 Monster Jam satin fronts on all 4 corners. Pretty close to even at just under 14 in / 355 mm front and rear. Remember the Protrac rears have 1 or 1.5 degrees of toe built in.

    Same setup as above except #TRA 5572- Twin spoke Jato rear rims and #TRA 3671- Talon 2.8 tires. About the exact same dimensions. Jato rears have the same offset as Stampede fronts it looks like. If not exact it’s really close.
