more free spin

By -
First I pop out drive shaft.
I rotate supar gear.
I learn free spin by my fingertips.
Second I set drive shaft,and pop out diff, I compare with before by fingertips.
I feel something heavy than before.
I remove center drive shafts.
I grue little thread lock into thread hole.
The grue is dangerous lock.
I never attach bottom of set screw.
If bottom of set screw adhesion with final pinion,
I can never remove.
This is only place using high power thread lock.

And i cram cream grease between final pinion and bearing.
It avoid for dust by inside high presser. 
I make little clearance between univ to bearing.
It's about 0.5mm.
I adjust same front drive shaft.
It don't concern with gear mesh between final pinion and ring gear.
Final pinion receive presser from diff forward center diff on rotation. 

Univ leaves bearing,then I get more free spin.
If I used Japanese high quality bearing,Free spin same as MP9.

Longtime free spin is not important.
Important things are accuracy of gear mesh and adequate clearance.
Stacking to improvement small things make large advantage same as life.

Reliability of FUTAB

 It is a valid concern, as that reputation did persist in the RC community for a time. Here is an explanation of the current situation and why that "rumor" no longer reflects the reality of their high-end gear. Is Futaba Prone to Failure? (The Current Reality) The short answer is: No, the current high-end Futaba gear is exceptionally reliable. In fact, it is considered the global benchmark for durability in the grueling 1/8 GP Buggy category. 1. Where did the rumors come from? Historically, there were a few reasons for this reputation: Heat Issues in the Coreless Era: Older high-speed coreless servos pushed performance to the limit. In 1/8 GP Buggies—where vibration is high and races are long—these servos sometimes overheated and suffered board failure. Complexity of Early Tech: Futaba was a pioneer in S.BUS and telemetry. Early adopters sometimes faced "troubles" that were actually caused by incorrect settings or power supply issues, which were then blamed on th...

I warry about Durango parts providing. AMain can provide parts after soon I put parts on cart or wish list. Probably they don't want to make dead stock. Then they watch customers need. I want bulk head. But it will stock on end of June. But I found another brand Arrma. Is the bulkhead same spec as DNX8? Is Arrma one of Hobbico brand? The picture is Durango. It is 2 dollars expensive.

Break In Part3

By -

This picture is same type OS engine piston. But each engines take different way of break in. Already you can understand. Left side is running in,right side is stand in.  Each engine left side is exhaust side. Thermal expansion lean left side continued long time. Then piston top scrape right side only.  And piston side doesn't scrape uniformity. Stand in disuse piston. Not break in,only do break. It takes a balance by chance for short term. So I said heat cycle is very important. Heat cycling protect piston to lean thermal. Perfect break in is like this. Piston top scraping belt width is uniformity on zoom up shot! AND piston side luster is uniformity.
