VS Racing D01-DLC Limited edtion

By -
The engine is made by Rody Rome.
The engine is a OEM of OS engine.
 Not only name emblem but also crankshaft are modified by Rody.

There is not counter weight.

Big end is coated by DLC.
It likes as TP engine.
It was Techno Power long ago.
 Crank was made with another material too.
DLC is a plating operation.
Plating operation needs heat treatments.

Heat treatments of plating makes crankshaft softer and flexible.
Flex crankshaft takes long time to maximum.
Then he coated DLC on big end only.

DLC effects on surface only.
Crankshaft operated heat treatment without DLC.

A Japanese engine tuner say same things about DLC.
He recommended non heat treatments like a WPC.

And I want to say about counter weight.
Crankshaft rotates thousands per a minute.

If weight balance has deviation,it make vibration.
Do you know how insert weight to crank.

Drill crank to make hole for weight.
Cool down weight with liquid nitrogen.
Heat crank hole,and into weight. 

Probably crank become weaker and to have deviation of balance.
To make well balanced crank is so difficult.

I order one.

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.
