MAKE TIRE

Image
I bought Proline M4 tyre M4 is made from soft material. Then it has some remarks. Proline tire has some burrys at bond area. AKA has almost no burrys. We should cut them. Wound sand paper. Scrape bond area. Soft material easy to catch dust and oil. Make air blow hole on sidewall. M4 should not open on surface. And use 2mm punch and open three holes. Wash both bond area tire and wheel with parts cleaner. I have tire glue jig. Put on with inner Nose of CA should insert to wheel rim. I insert pin quickly among bond area to flow CA well. I spray hardening accelerator befor pop out the jig. I use jconcept tire band for a hour.

Go to cafe

Image
I get compensatory holiday for last Saturday. But my daughters go to school. After I send them to school. We go to cafe at mountain side. Sankanzin is old fashioned outside. But inside of house is sophisticated. My wife drinks Kona Hawaii. Coffee made in volcanic ash land taste so good. And blowed by sea wind make taste sweet. Kona is one of the best coffee beans.

TRY AGAIN

Image
This is MP9 brake disk. It is expensive. But it is little wider for center diff cup. I don't give up to use it with stinginess. Aluminum papers are glued disk by CA. And diff cup are same as . They have just clearance. I'll confirm durability for next run. If it was bad,I will try Mugen disk. Because normal disks have 17g. Theses have 13g. Probably Durango designed disk that has cooling holes before on sale. DNX8 manual remain CAD picture drawing so on parts extended page. I think Durango changed goal of design on the way. First target is win of worlds with Ryan Lutz. Durango is become focus on club racer. Then design target change for pure racer to almost RTR. I want pure racer type. Almost people want Mercedes AMG not Maclaren Honda without driving technique. But I'm enjoying to grow up the car with try and error. And basic design is so good that I don't give up to improve the car.

Busy saturday

Yesterday our company 50th anniversary party was held at Yokohama arena. Ten thousands staffs got together in the arena. Finally Japanese famous singer Ayaka Hirahara had come. Her act is the best. And Japan Air Line invited our family Tokyo Disney Sea on Saturday night. JAL charter Tokyo Disney Sea one night. We enjoyed non congestion Disney Land night.  Usually Tokyo Disney land is on rush hours .

Rear body post.

Image
I replaced rear body post. I adjusted the post hight to cut. I mounted saucer by pin. The saucer has pin hole. Then it can move pitching direction. The post is for 1/10 tooling car. Then pin hole is thin. I use D815 thin body pin.

Shave weight

I answer Mickey_B's question. These are around rear hub parts. 355221 * 2 Drive shaft 355237 * 2 CVD coupling 980263 * 1 CVD PIN 353131 * 1 Upper ball joint 355212 * 1 CVD Drive Axle 980317 * 1 AXLE Pin 353358 * 2 Rear hub carrir 355250 * 1 Wheel hub Lansford 5mm x 64mm turnbuckle * 2 And Mugen shim E0206 * 1 Mugen diff shim If you have any other question,May I help you. I bent center rear drive,but I cant't buy spare. Durango doesn't mail me yet. Then I bought rear Mugen center drive shaft. Length is same completely. It's Mugen drive shaft. 23g. It's Durango. 25g Mugen have -2g advantage. But Durango looks cool. Center drive parts rotate most high speed. Then weight control is most important. Like brake disk,center diff super gear. We should think weight x RPM.

New engine

I purchased some products with Amain web system today. They can manage stocks realtime on the web. And they can deliver parts accurately. They never make mistake since I've dealed with for these years. This is very simple thing,but it's so difficult to organize such a system. I ordered a Triton L4 standard edition $310. Triton has modified edition $390 too. I'll spend more about $300 for Next fine tune. It's based on Picco boost 3TZ. Sink head is low hight type like a Nova. One of the Picco OEMs. Original sleeve has three ports. But I've never seen the engines sleeve intake port figure. Triton is proud of mileage. Probably it has many port than original. Crank shaft has counter weight. Another I bought Bitty wing. DNX8 has plenty rear traction. Then lightweight and low downforce wing is needed. It's a Jconcept silencer body for MP9. I want to buy assassin body but Amain don't dea...

RC CHAMP

Image
I came to RC Champ at Akihabara. It far about 2km from my hotel. I walk to the shop for diet. I bought Fugitive M4. The tire is increased prices by Japanese yen decrease. Now it takes ¥3000. But there is only two pair stock stay ¥2700. I'm so lucky. Last running on truck I loose rear center drive shaft set screw. Probably thread lock grue is too old to use. Then I bought new one. It's tooling car body mount. It might use for DNX8 rear body post. Especially the soucer is fit for carb of body.

FUTABA SANGYO

Image
Today I have been to Tokyo. This is Tokyo station sealing. Our company head office places near Tokyo station. After work I went to Futaba Sangyo RC shop at Akihabara. This shop is involved Futaba electric. Then this shop mainly deal with Futaba trancemiter  and Futaba servo. 4PX  no stock. It will be version up soon. It might become 4PX-R. I bought some Mugen parts for DNX8. Mugen parts have two type made in country. Ones are made in Japan. These are precious metal parts. Ones are made in Taiwan. These are plastic parts. Crutches are expendables. Crutche shoe are made in Japan. Shock end. It might fit DNX8. It is cheap. If it didn't fit goes junk box. I like this spring saucer. It has high spring guide. It is center rear drive shaft. Length is same 110mm. Probably Durango will never response my email about drive shaft. I think Durango might give up 1/8 buggy business? I had only one set +1mm hub. It is for rear. I can buy with ease except made in China.

SETUP

Image
Always I start to set up with rear traction control. Important things are balance of break rear tire and traction control. On small corner we want to slide rear at mid of corner but we want to recover traction for easy control at out of corner.   On high speed corner we want traction more but want  to avoid high side. On the truck I set +2mm hub. It feel too stable. I return normal hub and select center hole of upper link from inside hole. And roll center bush change outside-upper 1mm. Low roll center make rear break well. Then it make quick handling Wide tred and increase camber angle make rear stable. On front section I want more head down on breaking.  I change front roll center bush. FR bush is 1mm down. FF bush is 0.5mm up. Skid angle increases 1.5mm and roll center is set high. DNX8 bush is so clear to understand bush direction and height. Bar type means 1mm,dot means 0.5mm.  And I feel too late to wait on off power ...

For next

Image
DNX8 appears changing of drive feel for changing setup directly. It is a good point for driver. I correct issues after first run. I adhesion aluminum paper with CA glue. But it ware out. Then it makes clearance. I will modify another material. I replace original brake rotor. I will drill hole on the rotor. I want hop up rotor from Durango. Brake system can't allow negative factor. I used prebuild shock end. MP9 shock end has different pitch thread compare with DNX8. Then shock end pop out from shock shaft. Right side is virgin one. It is from spare I  had bought with kit. All shock are replaced new shock end. Center rear drive shaft is vented little when it popped out. Then I correct drive shaft with vice. I try to find spare one. I can't find where sell it. Probably Durango have not sold it yet. I can't find it on Durango web parts no search too. I write email to Durango support about how I can get it. I chan...
