4tec VXL?

[chicagonative17]

Who thinks Traxxas needs to come out with a 4TEC VXL?

I do. The thing would SCREEEEAAAAMMM!

Maybe if we make enough attention, we could get traxxas to make one!

yea but only if they revised their belt system.

[BloodDemon]

Yea I dont think that belts can handle that kind of power.

[chicagonative17]

The 4TEC 3.3 has a lot of power and the belts handle it really well. I havn't had any problems with my 4tec and I have the origional one (pro .15) with the new motors put through their paces in it.

Big difference between Nitro and Brushless. That nitro will spin 25,000 rpm. Brushless with 7 cells will hit 60,000 rpm. The belts will stretch loose just like on real cars with super chargers. Thoes only spin at 8,000 max. Belt and Brushless just isnt good right now. Mabie when some one comes out with a steel belted belt.
Just my thoughts.

[Hobson]

Belts are fine all the top race chassis use brushless and belts.

I wish they'd come up with a new design - the 4TEC is nearly a decade old.

[chicagonative17]

It would handle it. They could make it a tention belt wheel where there is always a spring tention pulling the belt wheel. This would always keep the belt on tight.

The reason I bring up a 4TEC VXL is the very fast the origional is about 10 years old.

I was thinking the same thing. I hope it is comming. They definatley need to upgrade it I think.

I actually had a 4-tec with 2 motors and 12 cells. Batts in series and motors in parallel. That thing was interesting. No ESC... Just a microswitch and some wire to short out the motors for brakes. It didn't really have any drivetrain problems. The trouble with it is that it doesn't go straight. There's SO much slop in the steering of those cars they're hard to drive even on decent pavement. I think Traxxas needs to redesign their onroad cars entirely. The Electric, I think, is a better layout than the nitro. It's just a cleaner, more efficient setup.
And yes, VXL for 4-tec would be cool. I need to get a couple of Titan 12Ts and a big gnarly ESC to try out sometime. Too bad I'm broke :(

Would be sweet. I have run brushless in my xxxs and I had problem with the belt skipping

I'd really like to see a new shaft driven 4-Tec powered by the VXL.

[Eli the rc guy]

Yea I dont think that belts can handle that kind of power.

In most cases belts can handle more power/high speed better then shafts.

[skylineTT]

i think that instead of using the belt design for brushless, they will come up with a new electric car entirely for the brushless system to be in. the rusty, bandit, and pede are all shaft and can handle the power with the revamped tranny's but they might design a new car, then put the brushless system in there. we should hope to see a new revamped brushless e-maxx too.

[Chachi_RC]

Yeah, ask away for them to make a brushless 4tec, and I'm sure they will listen. Just like the 1000s of other people who have asked for them to make an e-revo for the last 2 years, and look what they did.......They came out with vehicles that have been out for years, but re-did them......TWICE!

But like I said, ask away. I'm sure they will listen to your request, and produce it instantly. Good luck!

[Eli the rc guy]

Aw now I kinda feel bad for my cousin, he got the E 4-tec and I'm pretty sure he still got that little Stinger motor in his. ^_^ Poor little dude. How would you think that traxxas would have changed the 4-tec. If they changed the design completely they cant really call it the 4-tec then. Just add those new gray plastic parts, maybe toughen up the belts a bit, stick the VXL in there and put a new shell on?? I bet a lot of people had already done that ( except the gray parts) if they wanted to.

[chicagonative17]

The 4tec VXL would include:

1. New brushless motor and speed controler
2. Lipo capable
3. Tougher plastic
4. New body
5. An automatic constantly adjustable belt, (a belt wheel with a return spring on it so that there is constant tightening of the belt)
6. New tires
7. Redesigned suspension system.

It would be worth it, I would buy it.

chicagonative17, i like your idea about the automatic belt tensioner, taking a page from full scale cars on their serpentine belt systems personally I thin just making the chassis out of the new gray plastics, re-engineered suspension, and the velineon system. Tires are fine if you need better ones you'll go to another brand anyway, body I could see using a re-design. and I think the velineon already has a lipo cutoff doesnt it? they advertise using a 3 cell on the rustler, y would it not have a low voltage cutoff?

[chicagonative17]

I am not familiar with the new VXL systems. We have yet to see them arive at HobbyTown. Your are probobly right about the low voltage cutoff, I just wasn't sure.

[paperclipracer]

well and somewhat sad, that racing goes eveything is going brushless, and all the top touring cars are belt driven. they run 5-6 cells with mod brushless. so it does handle it

[TravisZ2892]

yeah I remember reading RC car action about the velineon system it does have lipo cutoff, its actually 2 stage. it cuts power to a minimum at one point and then it cuts power altogether.

[chicagonative17]

Travis: Thats good to know.

About the belt drive, I have full confidence it will work. I have witnessed a belt driven lipo brushless 1/10th scale car go over 100 mph at easily 60,000 rpm+. Even if a belt drive gives out, its cheaper and easier to replace than a shaft drive.

dude i would love to see it i bet it would be awesome

[chicagonative17]

If anyone is interested, the new RC Car Action mag has an article about the side by side comparison of belt driven vs. shaft driven 1/10th scale on road electrics.

If belts are so much inferior to shafts, why do 1/8 onroads use a belt drive setup?
Having owned both a Nitro TC3 and an R40, I'll stick with belts on my nitro onroads for sure. It's not as rigidly durable as far as rocks and what not go, but it seemed more efficient and more durable as far as actual horsepower-related durability is concerned.
