DNC

DNC had held. It's very exciting race! 45min brittle makes 2seconds difference. W Ryan get good engine and US taste car that have short stroke shocks. They decide  good selection leave for CRF engine. Then they can battle with Ty. This year worlds be in US. Kanai tests at Vegas. Japanese driver Matukura drives TKI4. He can buttle with big3. He is already worlds champ on EP. I'm looking forward to worlds. https://youtu.be/zo-TUJ8W3DQ

Bee hive

I cut masking with bee hive template. I copy template from my daughter math text. Many beehives are pasted like this.

Center diff

Image
Today I went to truck. I compare both diff. Normal 46T and mp9 48T. MP9 diff make the car lighten feel. On free throttle the car go forward. MP9 diff is more heavy than normal and break disc is more precious then the car go forward . And make the car quick. Probably MP9 diff has no frictions by precious inside gear mesh. I adjust shim tick on the diff gear on at first building. But normal only center diff has little frictions. I'll have to check front and rear diff too. I change shock saucer. I change to Mugen. Normal saucer is easy to pop out spring. I have no problem all day long. Only center diff changing, the car become more go forward and quick. I understand Center diff and break rotar is most important parts again. Then rear roll center change center position. I found base setup. But it's almost default setup. Although I can make the car moving well. Next time I want to find race level setup.

Ielasi tuned

Daniel Ielasi is a expert driver on road. He found engine brand Ielasi tuned. He developed buggy engine. It's manufactured by nova.  Square stroke and four ports. Same as ultimate M4R. But cooling head is different. Ultimate cooling head is low height. Square bore engine become big bore and short stroke. Then Crank become small. Crank receive less stress. But piston become heavy and get more friction. Piston and sleeve material is most important. Probably Nova doesn't find best material yet. Then Nove never unveil square bore engine from their own brand. Nova has most large amount of knowledge of material, but yet. And thermal expansion becomes more big. Then both brands try another shape of cooling head.

Clutch

Image
It is rainy and windy day in Japan. It is called first spring wind. Tomorrow race has canceled. I built new REDS clutch. Carbon and aluminum shoe are set half and half. And easy build shoe. Upper plate has spring receive mount. I set upper plate and turn to low position. So the clutch upper plate has each two holes. This is a REDS bell. It has cooling fan. Bell is most hight rotation. Then bearing receive stress. If bearing was broken not only bell but also engine bearing is broken. Then I use bearing grease. I paste among bearing. If do so I should use cooling fun type bell. So grease don't go into shoe. I replace bearing each running a day. I  maintain clutch bearing with this tool. Bearing is set into the tool and blow out old grease with parts cleaner. And push into new grease.

TPRO

TPRO is Sworkz tire brand. Sworkz place on Taiwan. Almost buggy are made in Taiwan. Sworkz products are high quality. For example clutch and shoe and bell are. Atsushi Hara and mechanic Miura are good for quality. Then named Hara products are excellent in the past. This is Hara bite. TPRO use new material for this tire. I bought pre mount tire at Spiral. Japan nats champion Ajishi made the tire. The punch three air halls on corner of side wall. Probably 3mm. And he punch another side too. But hole position is displaced on two side. Block of the tire is little smaller than AKA impact.But Little bigger than inside job. Then I build Impact. I punch the hole same position as AJ. I get two types of control tire.

MP

According from neo buggy Kanai tests new type wing. If you wanted to get race spec MP9. You should buy many hop up parts. Chassis , shock and spring,hub,drive shaft etc... Meaningless to buy the kit. Only can use plastic parts. Probably TKI4 include those hop ups. Kanai  can develop only MP line. Then he often improve parts. Then parts number are change at sub revision. It takes much money for maintenance Kanai spec. But He can improve MP9 high pace. Kanai is fifties now. Physical performance become weak. Responsibility, sight. Then MP9 becomes mild handling car. Long shock and spring make handling mild. And easy landing from big air.
