Cylinder head Temp

[Smitty]

Hey guys, checked my cylinder head temp yesterday and it read 200F, is that way out of line with what it should be. The DLE-61 runs great and never had a problem cranking or while in flight. Thought I had baffled the front and opened all the exit hole in the same way that Tom and Terry had done. This is on my Sukhoi-26M.---Smitty

Using an IR gun or other type of measuring device?

 

[Smitty]

Yeah a fellow flyer has a IR gun.--Smitty

 

[Bunky.F.Knuckle]

IR isnt the best way, but lets you know if you are close.

My question is, how does it run at full power, and how does it idle and transition?

 

[Smitty]

The engine runs great at wide open, idles real good and transition is fine.

 

[Bunky.F.Knuckle]

You are gonna be just fine. If air is being directed over the fins, dont worry about it.

 

[Smitty]

I am thinking of adding those open alum. louvers to the cowl to help air get out.--Smitty

 

[Bunky.F.Knuckle]

Any extra air you can remove, it will help!

Telemetry on my GP 61 engine temp average for flight 197
After a 30s hover 265
On a long down line. 140

Hope this helps
