Default New Class: 1/10 GPR Video

This video of a friend is of a 1/10th V-one-RRR powered by Novarossi (pink car) lapping a 1/8th 960. The RRR has been converted to the new lola-style Kawahara conversion including tires, body, and bumper.

http://www.youtube.com/watch?v=XBOah7AoHaU

The conversion kit includes:

1) Kawahara 220mm Body
2) Kawahara 2 x 30mm Front Tires + 2 x 40mm Rear tires (shore 35-42 available)
3) Kawahara extra hard front lola style bumper (it's super hard!)

Here is a link on the main web site:
http://kawahara-racing.co.jp/Ekawa.html

There are two kits: 1) To fit the Kyosho V-One-RRR and XRay NT1 and 2) To fit the Mugen MTX-4. Sorry Serpent drivers, no kit to fit Serpent yet

Tires, body and bumper are all sold seperately as well as in a kit.

A top-end Novaross .12 engine puts out about 1.6~1.7 hp and a top-end .21 puts out 2.6~2.8 hp. With 1/10th at 1750 grams and 1/8th at 2500+ grams, you get roughly 1 hp per kg for each car meaning you should get roughly similar speeds but you don't. 1/8th is considerably faster than 1/10th.

So if 1/10th doesn't have a power-to-weight issue, why can't you get more speed out of it? Part of problem is that 1/10th cars have much smaller wheels so getting all that engine power to the ground is definitely a harder job. In 1/10th racing a big frustration is the over-sensitivity of the car to changes in traction. Not to say traction isn't an issue with other scales, but with so much power on such small wheels it definitely creates a challange. With respect to traction issues, I'd say 1/10th is more difficult than 1/8th, at least in my experience..

This kit includes 30mm (front) and 40mm (rear) wheels which helps stabilise the car and get the power into the pavement. While the wheels weight slightly more than regular 26/30 wheels, the body is light. Downforce is also quite good.

I know a guy who can get me a few kits so if anyone is interested, PM me.

Thanks for posting. I've seen this kawahara set-up in most Japanese magazines, but I haven't seen the conversion in action. Very impressed and i'll be looking foward to trying this when I get the opportunity.

It is. In fact, it's one of the last few tracks left for Nitro.

Well... I doubt lapping an 1/8 car controled by a good driver is possible. I do not see the driver in the vid is a good driver, he slowed down the car a lot in almost every corner.

How about the lap times?
Is there a big difference between the original V1 and the V1 with the Kawahara kit?

Totally agree with u! can see that the 1/8 driver is not that skill as the 1/10!

At the risk of asking for too much, it would be great if you can takes pics and videos for us that can't make it. We would really appreciate it! Look forward to your reports!

Thanks!

I will bring my carmera with me and take some pictures.
I will try some video (from the carmera) ... since Collari and Fukuda will be there so we can see how the 220mm and 1/8 compared.

I think with the easier set up, it may bring back some of the guys already left but still have the touring car with them.
