SRX8

Worlds will be held at Vegas soon. But Travis parted away from Durango. He will use another brand car. He uploaded the picture for worlds using. I think it's a TEKNO. Front shock mount is high angle. Like this. But he drive HB. I expect winner is Ty Tessmmann. Low height engine head and new body are his advantage. If anyone beated ROAR drivers,member of EP worlds holders are. X-RAY top gun. Kyosho Matsukura. And how many new cars does unveil at Worlds. Probably Mugen . Their development cycle is 2years adjusting worlds. Ryan Lutz will be modified TEKNO.

It's Ty Tesmann D815 v2. Cooling head height is low! I think cooling head rear end should have more high than front end.  

I went to track today. I try low wing mount and rear weight. It's fine.So stable and rear traction becomes high. But fuel tank leaks at the cap. I checked sheel. No problems. Probably spring is getting weak. I watch amain site. But tank is out of stock. Dnx8 has already been out of list. And many parts are out of stock. Does Durango will go out engine buggy market? Through the caller for more tension. I will try it. Have I  to change another buggy?        

Is unveiled low cooling head engine. But I am interested in shape of cooling head. The head is little wider around rear side. Exhaust area has higher temperature than intake area. Then cooling head need asymmetric figure.   Ty Tesmann select the engine for worlds.      

I set 20g weight on rear end . M2C chassis already has mounting hole. The weight is made by mugen. Hole size is just as mugen.  

I went to park for new Picco break in. No one was there. There was 50 m over straight. It's 25 degrees C. No need preheating. I usually measured temperature at plug top . I must stop engine at fly wheel. It's for protecting oil empty. I did heat cycle break in. No idling. I run max throttle at the first time. One minute after cool down to 30 degrees C. Runtime engine head temperature had near about 100 degree. If engine often stopped should slow close needle 25 degrees. If plug top was cool should close 20 degrees. It's from temperatures too cool or too hot you should operate main needle. Range of temperatures 90 to 120. Running in method is good. Because high temperatures at straight end but cool down at corner. There is little heat cycle on the run. I did one minute x 4times. Two minutes x 4 times Three minutes x 2 times Four minutes x 6 times. After break in I watched piston. Picco piston hit under the top. Near the rear pinhole is important. Same width of hit ring is ev...

It been a long time since I post last. I went track on last Sunday. I tried high wing mount. It makes more roll. Then reduced response. I change rear spring to more thicker. It's good feeling. But I retuned low height mount. For jumping foam. High wing mount make difficult to jump big air. I'll try to put weight rear end. Now my car has 3500g without fuel. Then I can add 20g weight.   I removed screw at servo stay connected with battery box. Steering servo connect only steering plate. Then chassis flex free at front end. It makes direct feeling. I adjust steering servo slow.
