Altitude!

The SpitMk1a is short on legs regards top speed compared to the Hurricane as currently modelled. Altitude is essential but may be the following will also help.

Apart from Trim and avoiding Tight turns, set your Prop Pitch to give a comfortable 2700 RPM with Radiator partially shut - throttle does not need to be flat out - watch the exhaust colour and try to match throttle to give blue not orange - your engine will last all day long with those settings but keep an eye on coolant temp anyway. The Spits and Hurris need constant adjustment to trim relative to speed so keep an eye open. In combat you will need to go full throttle but open the rad fully to compensate for increased temps as required.

Fly Straight and level untill you get some momentum and airspeed of at least 200mph then start climbing but do not bleed too much airspeed by climbing too steeply.

Once you have some altitude you will find that you keep a lot of the energy and airspeed gained when dropping down and climbing again but avoid tight turns or violent maneouvres.

Forget the boost - it does nothing -yet! As for PP, this is a CSP Rotol unit and the objective is too keep the Merlin in the most efficient powerband - depending on Cruise or Combat setting. For Combat set PP for around 2700 RPM - Max RPM of 3000 is an engine killer and should only be used briefly.
