Which chassis should I get question?

[AndyjcClod]

Hi Everyone

 

I am after a really quick road chassis to put a brushless motor and lipo in.

I was was thinking between a..

 

58617 - F103Gt

or a

58555 - Le mans

 

Both are about the same price but I just dont know which model will be more suitable to stick a fast brushless and lipo combo in.

 

Any recommendations?

The 1/10 F103GT is a bigger chassis with more inherent stability than the smaller 1/12 RM-01. Being a more popular platform it is also easier to find parts for, as well as bodyshells as most touring shells can be made to fit. And although it's T-bar rear isn't as advanced as the PBLR design of the RM-01, it is stronger and still very much race-grade.

The f103gt is certainly the better option if you just wanna mess about. It's worth keeping in mind these chassis where never intended to have super low turn motors and as such don't have high ratio gearing needed for very low turn motors. 

Its not to say it won't work, just the motor may run very hot if you choose too lower turn. 

They are crazily quick cars though, they weigh nothing and waste very little energy.

In my opinion you are better off with a 4wd Belt driven touring car chassis for speed and stability.

The F cars take off at high speed due to their rigidness, so any small bump in the road can send them into orbit once you start pushing the 'scale' sound barrier

You can get the T cars up to silly speeds and they can handle a few bumps. Just take a look at the 'Top speed' thread to see what I mean.

I got a TA04 to near 80mph with a £40 Chinese Motor combo

I would tend to agree with the above. While I maintain that the F103GT is the more suitable out of the two options you are considering, a 4WD touring car would be better suited to high-powered brushless than either of them.

I run my F103 on a race-legal 21.5t brushless motor and 2S LiPo, and while the chassis and drivetrain are plenty strong enough to handle way more power than that, I am not sure that I can say the same of my reflexes. The chassis is extremely sensitive, both to control inputs and terrain variations, and provides a very, um, exciting drive even with such a modest power plant.

Surely it also depends on how you will be using it? Those F1 cars are fast until they hit a grain of sand and cartwheel. In the Tamiya range I would say the TA07 or TRF419 if you have the budget, or one of the shaft driven cars (which I know nothing about) if its primarily a basher as stones and belts don't mix that well.

[AndyjcClod]

Thanks everyone, so on a budget what touring car would people recommend?

[Percymon]

TB-01 is built like a brick outhose, but isn;t the lightest chassis as a result. You may be able to pick one up cheaply used.

You could start with a TT-01 used, or a TT-02 new starter kit (part build chassis, no body) or any TT-02 with a body you like / need for the speed element.  You may well find you have to upgrade a fair bit on a new TT-02 though for any reliability witha  big motor.

The good 'ole TL-01 is pretty crude but it get the job done with steel drive cups/dogbones and prop.

 

All depends on your budget and how much you want to throw at it in upgrades.

 

[Jonathon Gillham]

Given you want fast I would look at tye TA07 or the TB chassis but I don't know which version. They cost more upfront but don't need any upgrades. The TT02S would be worth a look too as they have quick a few upgrades already over the standard kit.

Or check out the speed run thread and see whats been done there, a lot of fast cars based on old and secondhand chassis

[Percymon]

might need the odd upgrade, but it come ready built with bearings..

Great option this one, £53 posted to the UK.

Ta02

[TurnipJF]

One of my mate's quickest budget cars is a TL-01, albeit the LA version with its race-inspired suspension. The TT-02S is the modern equivalent - a basic solid shaft-drive chassis with sealed internals equipped with race-grade suspension. That would be my choice.

[Juls1]

I would probably lean towards a tb03/04 myself. Maybe ta07

a TT02 is a great car but the money you'll spend making it run well far exceeds the extra you will spend to get a better chassis to begin with.

apart from crazy straight line speed what else do you plan to do with the car?

[qatmix]

Ta05 is a rapid onroad car. Only the TA07 rivals it. It runs rings around all the other onroad TC cars other than the TRF's.

I have a TA04SS, it started to strip the belts at 78mph

Which is why I figured the TB might be more suited to straight line stuff.

Not sure how the shafts hold up at high RPM's....I know the TT's struggle to put the power down if you have A LOT of power.

Thanks everyone, I listened and watched videos of low cars flipping on the smallest bit of grit so as that would mean I have nowhere to run so I treated myself to a second hand rolling TA-05 chassis which is now my restore project.

I will ill post some pics when it's up and running.

thanks again for the ideas and advice.
