The car is surprisingly good. Easy to drive in its' stock form. If you are planning to buy a nitro touring car, you won't be disappointed with a R40.

Alright, enough bitchin' mr. FREAKAH!


Fastharry,

So which is it? Which car is "THE ONE" for you?



You know what?......I'm not sure........I know I really like driving the r40.......It seems easier to drive than the tc3..but that may be cause its a belt car..


and the r40 can be manhandled like my Impulse......It has more traction than the tc3..and is just as stable through chicanes..

I know the r40 turns better..it has no feeling of low speed push..it also pulls into a sweeper better...you don't need to absolutley find a correct line like the tc3...

but nothing I've driven explodes down a straight like a tc3(cause of the shaft).....when you need power,it is right there...

I'll probably sell one of my tc3's.....and wait till next year.....

I still haven't been timed with both cars on the same day...so I'm not sure which one I'm faster with...

Next year I'll see what else is on the market,get my times with the r40 and tc3,and make a decision....

I'll tell you one thing though..

The r40 is a nice driving car..and its way easier to work on than other belt cars....

it does need to lose some weight..but its not bad like you think..its about the same weight as an Impulse...

but its 3 oz's heavier than a tc3...

the car has held its tweak and settings through 3 squeeze bottles of fuel....

I'm going to run the r40 AND tc3 in Edison's last race Oct 18'th...

see if I can compare times there.....Also,its a BIG board track....I'll see how the r40 takes to getting wacked around on a big track...

Traction, or lack thereof.......

I think that's the main reason why alot of the NTC3 owners here got rid of theirs.

I think that the NTC3's shaft drivetrain is so responsive, getting the power down in slick conditions is a bit more difficult. I noticed that I had to be really carefull in throttle application when powering out of the turns.

We have two classes of nitro touring at our track and one of them requires the use of rubber tires. This is where the lack of traction is evident in the NTC3. The other class(Mod) allows foams and the TC3 does pretty well I guess because of the traction provided by the foams. Our track being a tight technical one is another deciding factor.

BTW, track temps average 135 deg. almost all year long.

Like you said, the NTC3 accelerates like no other. In flowing open tracks the NTC3 does have an advantage. I guess you could say the NTC3 is sorta like a specialist.

Shafts is for open flowing med/high traction tracks. Belts for that and everything else. That's my take.

Default R40

Currently, there's only one R40 running at our track. I thought there would be a big boom like what happened when the NTC3 was released but that was'nt the case.

HPI scars?..... Maybe.

I'd love to see more R40's racing at our track.

Alright!

I think HPI make R40 to be a great car in stock form, so novice can just buy the car and drive good for all the pros can go and get hopup as they prefer. That's the key idea.

Just like other company that have a RTR and a Factory team kit. This is a first production of R40 and it's doing very well. I also agree with HPI to release HARA R40 edition later which Pros driver can be satisfied by all the hopups.

For Pro3 I use to have one and I set the track record for stock class with that car with nothing much on it beside upperdeck and aluminum shocks. At 2003 British Touring champ Pro3 just took the first place..how about that. People that b!tching about the car are the peole who lost to PRO3

Some people want hopups for just making the car looks good, but some need hopups for performance. You can built NTC3 with all hopups is that mean NTC3 need a lot of hopup???

....I should stop writing and go practicing, because that's the key to win!..not a car!

Default having engine problems!

So far the R40 handles like a champ when I can get it to run.

I'm running a TOP TT12 (turbo) with the glowplug it came with (C5 TC hot)
Trinity 20% breakin fuel, about six tanks through it so far.
HSN 3 3/4 turns out. LSN 2 1/2 turns out.

the engine will run fine for about 4 minutes using half-throttle blasts, then the idle becomes erratic, the rpms speed up and slow down, in a continous wave, then the engine dies. then I have to wait for the engine to cool before I can start it again.

help

Default front diff on yokomo gt-4

Hi All,

I'm a newbie to nitro racing..doin some research on on-road cars and came across the gt-4 at LHS...everthing looked cool on it and much better than the HPI RTR car...

But the question I have is about the front differential? Does it not have one? and is that a good or bad thing? less traction or more?

I'm not really racing, just going to be running it at a local paved school lot...

thanks in advance

I have. I have my R40 setup similar to my old MTX2 with rubber tires for the main track that I race at (concrete surface). It handles almost exactly like my Mugen. I had to raise the ride height due to the rubber tires being lower profile (raised a full 1mm).

Did you change the shock mount location to be more upright? Did you still use sway bars?

Was the handling/traction as good as foams?

The main reason why I ask is because I have a ton of unused rubber tires. Tried using a set on my MTX-3 but spun out a lot, of course I didn't have a front diff at the time and furthermore I didn't have the shocks in a more upright position which could of caused much of the lost traction.

Thanks,
Puma

No, I left the shock location the same as the book. I am using the sway bars. With Take-off CS32 in the front and CS27 in the rear, I get almost the same type of traction as foams on the concrete. However, I am not using the book suspension setup. I am using the same one as I am using on my mtx2 and mtx3. Camber is -1 on all four tires. I am using -0.5 toe-in on the front and -3 toe-in on the rear. I am using a track width of 199mm front and 200mm rear. Caster is the same as the book. If you are using Proline rubber tires, try S3 tires on the rear, S2 tires on the front. I hope that this helps you or at least gives you a starting point.
