SRX8

I've been to Tokyo. I went to RC shop Champ at Akihabara. I bought some parts. I doubt only front under spring weight too heavy. Then I'll try to replace under kingpin ball. A ball is 6g lighter than original. Another are expendables. OS plugs fit with PICCO. OS plug is the best. These are for shock. I want to have option 48t spur gear. I'll try to mount MP9 center diff. If these could mount to DNX8,I buy another diff parts and mount break disc. I want to make low downforce wing for long jump stable. Bitty wing is similar EP buggy wing. Trifecta has center fins. I like Trifecta for GP buggy.

Triton L4 is made by Lance Heidmann. He had cooperated to design and develop with Picco. Then the engine is similar as Picco. Left side is a Triton. Right side is a REDS. Low and taper shape is a advantage. Carburato is a weak point of Picco. Then REDS developed side needle carburetor. But manufacture is same as other Picco. So I change to OS carburetor. It gives stable low idling and high response. PC is same as REDS. But crank shaft is same as PICCO racing. Toriton select more effective parts than others. It has cost performance. I like it.

I wash buggy with simple green and air blows. I splay simple green to buggy without radio system. I blow out bubble. After washing buggy I wipe up. And I splay silicone oil to variable area.

Yesterday I went to truck. Five mates have came to truck. A expert driver checked my DNX8. He felt too much under steering. He changed steering EPA on the ground.  I set EPA on maximum droop at building the car. Then steering angle is set small. Now I set droop 102mm short. I should set EPA on the ground. I can get more steering angle. After changing EPA the car character is set too quick. And Triton engine is getting more and more high power. Then setting became near normal set up. I can't get racing speed yet. But it became much better. My car can't go forward after break with free throttle. Then I can't connect smooth corner and corner. My experience it caused under spring heavy weight only front. Buggy is necessary for under spring weight to get traction.  But only front heavy weight can't go free rolling. I modified rear end.  Then weight balance is collapsed. I try change front under ball to Mugen as same as upper....

I'll go to our truck today. I change set up for quick handling. Diff oil are set 5,7,4K. Active caster is set 2 down. And front under bush are set row roll center. Rear wheel base is set +2mm. Camber link is set most short. Droope is 101,122. Ride height is 25,26. I'll try many variations for race pace. If l found good setup I upload set up sheet tonight.

I search 48t spur gear. Does Durango have option spur?

9 Front kick up I want to get much weight transfer. DNX8 chassis have little front kick up. It si adjusted by lower suspension holder bushes. I'll try FF 2 up and FR 0 up. Pro drivers set front roll center upper side is high hole and lower bush is center. 10 Rear roll center I think  Rear roll center is adjusted with suspension holder bush and inside camber link position. I modified rear hub carrier for adjustable roll center. And hub width is adjustable. Pro drivers set upper link inside lower. Bushes are selected center. I think rear roll center setting is most important for drive feeling. We can understand easily roll center. We set suspension arm vertical. At the time row ride height is low roll center. We can adjusted sliding start position. We can feel row roll center quick steering. If I had plenty time I want to change step by step confirming effect.
