Transient Problem? Flap Drag.

[Tinkickef]

Anyone else seen this? It may have just been a glitch on my particular PC at that time.

 

So I do not set takeoff flaps on takeoff, just wind in some backstick and right rudder on the trimmers. Then I noticed the AI setting 10 degree of flap when taking off, so next mission I tried it.

 

Duly took off with flap, raised them and circled the airfield waiting for the wingman to take off.

 

Something in the flight model did not feel right, it felt clumsy, it could not go faster than 200mph at 1500ft QFE, and the cylinder head temp would not climb above 100 degrees, despite cowl gills being closed.

Double checked flaps and gear. Both up. F2 view to observe gear position - up.

 

Thinking its a bug needing investigating, I restarted the mission and took off without flaps and everything was normal.

 

Restarted again with flaps and the same scenario, low performance like flaps causing drag and odd flight behaviour.

 

Restarted PC, tried same mission again with flaps down at takeoff, raised the flaps and everything was normal. Aircraft and engine behaved nominally.

 

 

Perhaps something to keep a look out for, although I am thinking it was something on my machine that had not loaded correctly.

 

 

Edit. One more thing I just remembered... On the first event I experienced engine surging and realised I had not locked the primer pump handle,which I proceeded to do and the surging stopped. On the second flap down attempt I locked the handle before engine start. I suppose the primer pump as part of a combination of factors could have something to do with it.

 

 

loadout was 100% fuel and a 500lb bomb on the centreline.
