Long stroke engine

By -
I run SRX8 with B2012 engine on our truck.


Expert says black head makes over heat on summer.
Silver head version is good.
It can cool down more than black.

Or you should change normal head.

I want more torque on five jump on backend.
Another section the engine make good truction.

Next run I use Picco with os carburetor.
Os carburetor make stable idling.

Triton is almost same as Picco.
It has torque and long mileage.

It’s new Picco.
It has silver head and new carburetor.
Bore 16.03
Stroke 17.30



It’s new OS.
Bore 16.4
Stroke 16.55
Square stroke engine becomes little long stroke.
I want to try it.

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.
