Stampede reborn?
 
4 Attachment(s)
Witness the most tweaked and retweaked stampede on the planet. Took so many nights to build it the way I like it that I almost don't even feel like talking about it. There's a custom chassis brace system I made on the bottom with a compartment for holding my 3S 6Ah Lipos. That's a sideways slide-out cover on the bottom to protect that battery. Beside's giving rock bottom CofG, you don't have to remove the body to change the pack. very handy! 100% steel tranny innards and a basic 5200 complete the deal.

That looks pritty nice, what shockes are those? Does anyone know is some jato shocks would fit?

cadima 01.14.2007 01:05 AM

they're just the traxxas big bore Al shocks with silver socks over the springs.....
last I checked jato shocks weren't a direct fit. The stroke is wrong for the back as well.

hyperasus 01.14.2007 05:34 AM

Looks very nice. What kind of speed and runtimes you get out of it?

Sylvester 01.14.2007 11:04 AM

Looks good! Bet she is pretty quick.

cadima 01.14.2007 11:42 AM

Thx. Haven't clocked her, but she's so fast I get nervous at WOT. I'd guess around 45-50 mph or so. Too fast for a truck honestly. Traction is the hardest part. Even Med Komodo dragons spin to baldness in no time if I'm not careful. I had to get some street tires for when I mess around on the street or I'd go through dirt tires within minutes. Runtime is like 25-30 minutes just fartin around at the tracks.

Sylvester 01.14.2007 12:05 PM

That sounds logical (runtime).. as for the speeds, it may feel as if your going 45-50, but really its probably around the high 30's low 40's.

Mike.L 01.14.2007 12:05 PM

thats good to hear...for about every 2wd truck tires will go bald quicker

cadima 01.14.2007 12:10 PM

I assure you it over 40 mph. I was clocking around 40 mph last revision and that was with revo response tires and a Lehner 4200. Since I have added the smaller lighter anaconda's (also less roll resistance), and the 5200 with it's completely maxed voltage.

Sylvester 01.14.2007 12:14 PM

Mike : Yea, tires go quick on pavement, not so much on dirt/grass.

Cadima : If your clocking it with a radar than it is over 40 (unless your using the hot wheels radar ;) ) .

I agree, I have a T4 that when i run a 3s lipo, i thought it was in the 50's, but with a radar it was only 45

Mike.L 01.14.2007 10:10 PM

For me i would have someone drive along a straight road with me in the car (window open), and have my buggy toping out and trying to go at the same speed as the car.

would probably be the bast way for ME to see how fast its going. And ill know that im getting a acurate reading.

hyperasus 01.15.2007 12:32 AM

LOL

I can see so many things going wrong with that method LOL. Any of you seen Oceans 12? LMAO

I don't trust my driving enough to do that.:007: Be my luck it would be like the monster truck video from XXX main, right under the truck:035:

hyperasus 01.15.2007 05:26 AM

Video you say? Link please.

Mike.L 01.15.2007 11:25 AM

yeah link. I can ceep it straight, i would have some safe distance away from the vehicle anyway.

I've been meaning to get a radar but all my budget now is toward a Jammin CRT conversion that will get RC truck of the year when it's done! I just used a buddy to time me over a 100 foot stretch, and calculated the speeds. You'd be surprised how repeatable the measurements were. But in all likelyhood, it's around 45, not 50. I've seen pedes hit just over 60 but they needed 5s voltage and the motor couldn't handle it for long. Personally, anything over 40 is a waste to me for a truck. I wouldn't think of doing the drive along method. Once you get a little pede going 45 or so, tracking straight is not too easy!

We have a 42mph Pede, I too was convinced it was doing 60 :)
However, lately we ordered a MambMax/Twist combo. According to the speed calculator we could see upwards of 60MPH under 3S. I can't wait to try it out this spring :004:

Sylvester 01.16.2007 06:36 PM

Yea, but after seeing a 2.5 jato go all out at my hobby shop, i could say my B4 is VERY close to its speed, but i can say right off the accel is a ton better than the jato.

Mike.L 01.16.2007 07:29 PM

hmm....that means both of ours should easly hit 50MPH? IDK sounds odd i doubt it goes that fast...unless your using lipo.(but your saying this when you had those gp3300s still?)

Sylvester 01.16.2007 09:24 PM

When i tried it on Gp3700s it was fast, and i didnt even have it on full throttle settings! It was almost too fast, i dont know if ill handle lipo, but thats what the esc is for ; adjustments!

Mike.L 01.16.2007 09:35 PM

its going to be quite alot for a track unless you decrease the acel alot:)

Sylvester 01.16.2007 09:36 PM

A steady finger helps alot too.

Mike.L 01.16.2007 09:44 PM

Yep thats one of the key steps to becoming a good racer:)

cadima 01.17.2007 11:18 PM

you guys crack me up! All that work to transform the pede and make a Lipo comparment integrated underneath the FLm chassis, which allows me to swap batteries without pullin the body, and get my CofG to minumin, and I get quibbling about speed. give me some props please!

hyperasus 01.18.2007 12:36 AM

Awesome ride cadima. Love what you did with the battery compartment.

There is that better LOL.

neweuser 01.18.2007 12:45 PM

Hmmm, Lipo underneath? Can we say FIRE!

LOL.. That is asking for trouble, though.

that is my point. he made a batt mount underneath....

Sylvester 01.18.2007 05:35 PM

Imo id prefer a higher cog with better saftey rather than the opposite.

To clarify, it was not my idea, read back...:035:

Sylvester 01.18.2007 08:30 PM

I know that! I was just making a personal point there!

cadima 01.18.2007 09:35 PM

The battery compartment has a cover that slides in and locks which fully shields the battery. My current cover is nylon at about 0.150" thick. I use two gorrilla straps for insurance keeping the cover from sliding out. Wouldn't be hard to make the cover Al either. In fact you'd only need a belt sander to file the ends to an angle. I've just moved on to different trucks and the nylon cover shows no signs of issues after over a year. My pictures don't do justice I guess, but I think you're jumping the gun on calling it unsafe. It also accepts a 9 cell pack if you prefer.

Thanks hyper....

coolhandcountry 01.18.2007 09:57 PM

I think it is good idea. The cover should protect it pretty well.
Just make sure the pack can slide around to much in the holder.
Nice truck.

cadima 01.18.2007 10:15 PM

thanks again cool. There's foam in the back, and slight interference of the bottom plate to the pack which pretty much sandwhiches it in. I guess for thinner packs you could put foam rubber strips on the plate as need to get your squeeze. Well, works perfect for me so far and this truck is no shelf queen.

Since the recent comments I have added a warning label requiring outdoor use only, for adult use only. That should cover me.

Procharged5.0 01.18.2007 10:27 PM

Nice Pede. Looks like you have a lot of time invested in it!

cadima 01.18.2007 10:31 PM

yup. wife bought it for me as my first r/c truck 2 yrs ago. got the sickness. now here i am where I can share my disease.

Procharged5.0 01.18.2007 10:34 PM

We all have it....in varying degrees! :024:

cadima 01.18.2007 10:41 PM

fortunately, the side effects are intermittent for me. Unforunately, I've had it bad last few months working on the CRT re-version which is quite a bit more advanced than the pede... Maybe a post on the project will make me feel better.
