Default Hara's car

Oscar,

Is there any chance of you posting a picture of Hara's car. I was able to talk to him in Portland at the roar nats and look at his previous car. I would really like to see the difference between the two versions. Can you share any differences in the Orion v2 motors between a touring car setup and a 1/12 motor setup? Are you using a different arm styles?

Thanks,
Steve

Than lots of suntan lotion, which is rubbed in for a few minutes. About 30 minutes before the start the tires are very carefully dried with a towel, to have them sticky dry before the run. I questioned here drivers why it gives more traction, but they say they do not really know. They are only sure that it gives more traction.
Functionally speaking, the suntan lotion is being used to seal the first coating of sauce in, thus making it last longer and act like more of it was applied - very useful in a 8 minute race.

Suntan lotion by itself actually produces less bite than most conventional tire sauces. I personally use it if I ever need to free up/loosen up my car.

I always heard about using sun tan lotion for foams in outdoor...i think that was Josh Cyrul who posted it on his thread...but i always asked myself if any sun tan lotion its ok...or must be an especific brand because of his chemical components....

I think any brand will “work” but I’ve found Coppertone specifically to be the most consistent from bottle to bottle.

Of course, it tends to cost the most also.

Suntan lotion actually helps keep the tires clean. If you were to use just Paragon the tires would pick up every dust partical on the track and the car would be impossible to drive. The lotion allow the dust to fly off while the compound stays in.

Ohio Gozaimades from Japan.

First final just done. Masami, Kimura, Hara. Hara led Masami for 7.30, but used too much juice.

More later....

Okay, questions and answers first:

@ Anders: Thanks for helping me with my report. Like mentioned Masami is far far far away. Yoshioka is not racing.

@ Corallyman: I have no pics of Hara`s car, but I advice to look at some Japanese sites. Have seen many of them making pics here.

In regards to motors settings:

1/12th
9 or 10 turn double modified type, softest springs, edge sprint brush. Timing 3-4 mm. Around 37mm/rev for 9, 41mm/rev for 10 turn.

TC
7 or 8 single modified type, extra hard springs, edge sprint brush, timing 1-2mm. About 9.5 ratio for 7, 9.0 for 8 turn.

I advice now to choose for Modified type armature-motor in case of no motor limits. Touring car type motor-armature in case of 10 or 12 turn motor limit. This advice due to the latest increase of battery power.

@ Pizza: Dude, I know now here he is using KO speedo, no idea what happened with the GM one.

@Pyramid: Masami will and has never change for money.... just a note in addition. If else he would have been driving Monster stuff already for ages
