4.101 RC - List of fixes

the rest of the spit characteristics are fine imo, the aileron fix is appreciated and it seems... well, it seems to give more warning of a stall, and require flying properly. as this is the case, will "spitnoob" become a phrase of the past?!

A Spitfire V as tested by NACA went practically into stall with the elevator still depressed at about 4° (~25% of travel). It did a 3g turn at 170 mph with the elevator at about neutral. Think about that when you check in game behaviour.

The neutral trim point of the elevator trim can be set by the pilot in game, so I don't think it matters much. I just trim it down a lot on take off and then have more fun flying the thing than I ever had before.

I could not visit the only site I could find reporting on this NACA Spit test you quote-the browser forbids the site as unsafe.(ww2aircraft.net)

Could you find any such data on the heavy trimming necessary on the Spitfire, from a British source? Like the spitfireperformance site, for example?

Engineers have been known of mounting the things upside down on unfamiliar foreign equipment, you know.

Any trimming increases drag, reducing speed. Not irrelevent to a transport, you see.

Ahm, what's this:

' "It happened that Wright Field had the only Spitfire in America-a Mark V. Unfortunately almost every pilot in the Air Corps had had a go on her and like a car that had too many drivers, she was the worse for wear...'She was very tired, very sloppy-she'd had the guts caned out of her all right."


NACA got it for testing after that.'

Hmm? How about looking at the sources that say the things you may not like , too ?

this is incorrect. you use trim as it has a lesser drag penalty than using stick controls. a correctly trimmed plane should fly faster than the same plane being kept level using pilot input, no?

JtD - as for neutral trim point being settable in game, how would i go about doing this, or do you just mean dialing in trim for straight and level and that is the neutral point?

If you 'turn' the whole horizontal stabilizer plane to get the plane in trim for its 'most important' flight regime (certain airspeed), you get less drag at that speed than by deflecting the elevator by a trim tab, increasing the elevator airfoil chamber.

This is one reason for 'flying tails', too.

Accordingly, it would have been quite sloppy from Supermarine to deliver such a plane NACA is talking about. It would mean the drag in order to neutralize the wing-lift moment (trim drag) is higher than neccessary.

Yes, that's what I just mean. It was poor wording on my part, sorry.
