Blenheim operating limits and checklists

[Vengeanze]

I'm having a rough time keeping the temps within limits.
Either the oil gets too cool or the engine temp too hot.
There's no margins for error.
Any tip would be appreciated.

I found the tip of quickly turn on/off autopilot to lock tailwheel a tremendous help while warming up.

According to Blackdog and Fleas manual I should take off with rads closed but that doesn't work for me. Overheat before tailwheel lifts.
