Title: Milled heads pics for Charles
Post by: RandySmith on May 05, 2016, 03:42:20 PM: These were slick heads with no fins, some cut before or after anodizing
Huge difference in performance in the 40 engine with these as opposed to the no fin heads

I just saw this.

WOW! Really nice work, they look store bought! H^^

I'm guessing you had them anodised after the tooling, correct?

The one on the end has a solid area, could you please explain that head?

Thanks for that BTW.

Hi Charles as I stated I cut some before and some after anodizing, the head with the corner left goes to the front intake side of the motor.
Some also have fins cit into the side of the head, as well as the top

Randy,

If I decide to keep that Enya Classic, I'll send you the head. You do do great work! H^^

You can have it anodised after the tooling?

Can you have small stuff anodised? Chromed? ;D

Bill,

Exactly, thank you.

With that second head you could test runs.

Are they available new?

In all honesty I would just run it as is. Enya hasn't been in business all these years for nothing. I haven't seen anything but quality engines come out of their shop. See how it runs and then make a decision.

Thanks Bill,

That's good advice, I'll take it!

I'm thinking of designing a Fokker Dr-1 for this engine.

36" in span, possibly 42" in span.

I'll look for a good three view or find a set of plans.

Thanks for the reply.

Charles
