Short course race trucks

[ogshotgun]

lets talk rc trucks 3210032101321023210332104original traxxas slash 2wd converted to a sand dragster i live by the beach its a wheelie machine and fast at Cabrillo beach , iam converting it back to short course stay tuned ... lets see yours

[Get Some]

That's no original with the brushless motor

I spent a few hours trying to race a 2wd around a short track. Got a 4wd and its a night and day difference for handling. They're 2 separate machines. Not a lot of positives about the 2wd in comparison when on a track.

I say keep as a sand beater and grab a 4wd. FWIW, I sold my very clean 4wd with 2x's 2S lipos, 2 sets of big bore shocks, 2 controllers, 2 sets of wheels/tires, stock motor and speed controller, extra a arms, extra al motor plate, more pinions than you can shake a stick at plus a castle S/C installed for $300.

Why not RC Boats? haha

Nice truck. I have tried to get into the SC trucks, but just can't. I still prefer my ST trucks. It's kinda like the old Days of Thunder quote. The SC weighs twice as much with tires half as wide...and the ST weighs half as much with tires twice as wide.

Also another fan of the Castle system here. I have the 3800kv, and love it. BTW - sand paddles work really well on snow also.


My next land vehicle will probably be a Stampede 4x4 or Slash 4x4 converted into a truggy. If not...it'll be a D8T, 8ight-T, or ET48.



And Mateo...boats are kind of fun, but they seem to lose the fun factor fairly quickly to me. I did build an airboat out of a kids foam kick board and a pair of EDFs, and that's kind of fun.

Why do you think I sold my truck?

10 years ago I was pretty deep in 1/8 scale nitro racing. My son was born and it all stopped. Fast forward 10 years and Santa brought him a 2wd Slash. He LOVES it, as do I. My wife has a E-Maxx and I just bought a 4wd brushless slash. Every Wednesday at 2pm we go to a local park and play for an hour before work. We made a little track in the back corner under some big trees.
The family that plays together, stays together.
I will be getting my 1/8 scale out of storage. Batteries are boring.

How does the traxxas velineon brushless motor and esc stack up against some other systems? My buddy is selling this set up for $80. Thinking about upgrading my sons brushed 2wd Slash to brushless. Do I put this in his or do I use it in my 4wd Slash and give my son the traxxas system?

That's an OK system (that system new sells for about $100). They are not the highest quality on the market...and aren't the most powerful. I believe they are a rebrand of the Hobbywing stuff (or vice versa). Also, I am 99% certain that sensored motors are not waterproof (not sure if that matters to you). It will definitely be a step up from the Titan 12T in the Slash now.

The Velineon system is good as well - but a 4wd Slash is the limit of that system.

But one of the most powerful, most reliable, cost effective, and "best" systems out there right now is the Castle Sidewinder 3/3800kv motor combo.

It's a 4 pole 3800kv motor paired with a waterproof ESC that can handle 3s in a 2wd truck (it can be used with 2s in a 4wd...and it will have better performance than the Velineon system - I'm just not sure it would be the best setup for a 4wd Slash). Very tunable...and very powerful. The combo can be purchased new for about $105.


If you are upgrading to brushless (especially the Castle SV3 combo) make sure the carriers have bearings instead of bushings and if you break a driveshaft, replace them with the HD driveshaft p/n 6852X.



Another option - if you want to move the Velineon system to the 2wd and step up the power in the 4wd you could go with the Castle MMP/2400kv combo (about $180 - and I don't think the MMP ESC is waterproof) and really have a hot rod.

i have never used that system i run the castle brushless censored but that censored too with timing,,the traxxas velinion system i kept burning up but that was me

[MrDenton]

Waterproof, sand proof, dirt proof...all the above. I didn't like the open ports on this motor. What about the Mamba Monster? If that's a sealed motor, what's your opinion on that for my 4wd?
Aside from the carrier bearings, what else will the 2wd need with a brushless upgrade?

The driveshafts are really the only other thing I can think of. With the VXL system, the stock ones will probably be fine...with the Castle 3800kv in the 2wd, I would really go to the 6852X driveshafts.

The Mamba Monster...are you thinking about the system or just ESC for the 4wd? The Mamba Monster 2 combo with 2650kv motor would be...well...awesome - although still quite heavy. A MM2 ESC with Castle 2400kv 1415 motor would be good. Either way, for the 4wd I'd probably upgrade to the King Headz motor mount - and if you do the Castle 2650kv 1512 motor...you might need to change driveshafts and shocks also (though heavier weight oil/springs might get the job done as well) due to killer power and increased weight. If you are just talking about the ESC, then it is waterproof. Depending on how much money you have to spend, it's great. But the ESC alone is around $150. You can waterproof the Mamba Max for pretty cheap yourself...the downside is that you void the warranty.

[MrDenton]

We do bashing at the park and the dried up lake beds. Think I'll just get him a traxxas system off ebay. Sounds easiest for now. Not sure I need much more power yet.
Also, I have a boat to finish.
Thanks for the info.

For what it's worth, you can usually buy a new Castle 3800kv system (which is waterproof) for cheaper than a new VXL system, or about the same price as a used VXL system. I REALLY think Castle system is better. Also...with Castle Link or the field programming card you can dial in how much power you want for forward, reverse, and brake...as well as set torque limiting.

[MrDenton]

Hmmmm...I'll look into it then. Sounds like a sweet set up.

That's I nice set up. You'll have to excuse my ignorance here, I'm a ex nitro guy. This LiPo brushless esc stuff is all new to me.
Would I be better off running this on my 4wd and the traxxas stuff on the 2wd?
2 or 3 cell LiPo? Why can't I run 3c on the 4wd? Too much load? What if I want to run a 3c, what would I need?
I have 5000Mah LiPo's, I get about 30min runs, how will that change?

First, to explain kv. That is RPM per volt.

2400kv motor: 2s lipo @ 8.4v max, 8.4x2400=20160 rpms
3800kv motor: 2s lipo @ 8.4v max, 8.4x3800=31920 rpms

The VXL system is a 3500kv 2 pole system, the Castle is a 3800kv 4 pole system. Ideally, for off road type stuff the lower the kv the better. But the difference between the VXL and Castle is that even though the Castle is 300kv higher, it is a 4 pole system which delivers more power. Also, the motor and ESC are a little more robust.

It is ideal for a 2wd on 2s, and can be run on 3s - just make sure you watch the temps on the motor (use a temp gun...and keep the temps under 200*, but temps in the 160*-170* are better). It is more efficient than the VXL system...and right now with 5000mAh batteries I'm getting run times of at least 20 minutes driving it on a track - I have not hit the LVD cutoff yet. Run time is somewhat hard to speculate on...because it all depends on your gearing and how you drive.

For the 4wd, it can be run...but only on 2s. That is because of increased load which translates into increased heat, some folks have run it on 3s in a 4wd Slash...but you have to pay close attention to the heat in both the motor, but especially the ESC. The Sidewinder ESC is really the weak link when running it in a 4wd. To be honest, the VXL system in a 4wd Slash is actually on the verge of not being enough motor - and can be easily "killed" by running too much gear. The 3800kv Castle system is still more robust, so it will still perform better than the VXL system in a 4wd Slash. If you run the Mamba Max or Mambo Monster with the 3800kv motor, you can more than safely run 2s - and it should still perform well on 3s if you pay attention to the heat and change gearing accordingly.

If you want to run 3s only in the 4wd the MMP Pro combo would be better. It's a Mamba Max Pro ESC with a slightly larger 2400kv 1415 motor. It will be noticeably faster than the VXL system...the downside is that the MMP ESC is not waterproof. You can waterproof it yourself for almost free, but it will void the warranty on the ESC. I'm not sure how much water you encounter? If you need waterproof, you can go for the Mamba Monster 2 ESC and the 2400kv 1415 motor. This combo on 2s will be quite slow.

And...if you want to get really extreme, you can run the MM2/2650kv 1512 system. It's overkill...and will be crazy power. Also a bit more expensive.


I haven't had my coffee yet...so I hope this isn't clear as mud.

I like anything RC, except planes...I crashed too many of them....just not that coordinated with them...but this stuff looks like a lot of fun....there's a couple nice shops in town..I'm thinking about building 4 wheel drive something for the summer to take to the lake with us....

[MrDenton]

These 1/10 scale slashes are bad ass! I can't believe how durable they are. Since Christmas we run them at least once a week bashing around the local park, hills and lake bed.
Here's the list of parts replaced so far.
Slash 4x4 brushless: 2 R pins
Slash 2wd brushed: new motor, my son ran through some mud that wiped a bearing, $22.
Badlands Proline rear tires with Beadlocks. Made it more drivable on dirt.
I'm sure there's better, faster and stronger, but for an RTR, you can't go wrong.

Ok FormulaZR, I have another question.
I've been playing around with friends motors and gears. Here's my decision. I'm leaving my 4wd alone and putting the traxxas brushless system in my sons 2wd.
Here's the questions.
My wife has a 10yr old E-maxx. Runs 2 6 cell NiMH batteries with the stock motors. I want to up hers a little. Nothing crazy, want to keep its reliability but gain some speed and run time. What's you're suggestion?
I also have a 1/8 Ofna nitro that's got more upgrades than I can remember. I want to convert it to brushless. My local Hobby Town says about $200-$250. What would you put in it that would be in that price range.
If you want you can email me.
