Blenheim operating limits and checklists

[Vengeanze]

Ok, I can take off and cruise no problem. But I'm concerned about the small margins when I take off.
I've read here that some of you take off when CHT is around 200. If I do that I'll overheat so I let CHT drop to 180 and then decidedly push throttle to max for +5 psi. At 80mph I quickly rotate and retract gear and ease down throttle to 60%ish and dip nose to gain speed to cool engine.
If I pause there and check CHT it's very very close to 240.

I run the cross-country mission so no bombs but full tank.

Any tip on how I can keep CHT down at take off?


Edit:
Btw, is the only way to load bombs to use FMB or online?


Edit 2:
One thing that struck me that I gonna try right now is to slowly increase throttle so I keep temprise minimal while gaining speed. Brb.
