What am I doing wrong? 2-stage prop spitfires.

if that sideslip was there all the time you could have gon even faster by correcting it.

I'm sure I could have gone faster...
I was trying to fly as even as I could with just rudder and elevator trim. with out aileron trim I couldn't get it dead straight.

I had half a tank of fuel and full guns... radiator half open... and didn't even touch the boost cut out.

With 5% fuel, empty guns, fully closed radiator, and throttle pushed through the gate I think it might do 355mph TAS.

What high alt are you talking about? That Aicraft is horrible to fly at high alt, handles like a pig and is very easy to overcook the engine

The original poster said he tested at 4000ft. The spit mkI had it's best speed at about 17 or 18000ft. That's much higher altitude.
The spitfire flys beautifully at any altitude. At least when I fly it...
maybe you just need a little practice

Someone suggested the mkI and mkIa ingame are running on 87octane at 6.25lb of boost and the mkIIa is running on 100octane at 12lbs of boost. Supposedly the mkIIa's running 12lb of boost still had an old boost gauge that only went up to 8lbs though. I vaguely remember checking this ingame.

Anyway that would still make our mkI spits more like Battle of France performance not Battle of Britain performance.
The 3d model on the mkI is a DH prop and the 3d model on the mkIa is a Rotol prop. If you look at them from outside. Same prop models as on the hurricanes.
