View Full Version : Oleg -Plz Read - P51 Elevator Problem

I noticed the P-51 LOST its bad SPIN (on backpressure) characteristic when the right Elevator & Stabilizer was shot off.

The P-51 Elevator characteristics were retained from the P-40 design ( a heavy elevator ). However, in FB, the P-51 goes into a spin if you use too much backpressure. When you loose your right elevator and stabilizer, you loose that bad spin on backpressure.

The P-51 elevator characteristic should be the same as the P-40, but the P-51 had a much faster roll rate.

Please double check your flight model stats regarding this problem.

Thank you.

P-51 tested hardly by the real pilot who fly this bird sometime now http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

He posted his thoughts already once on this forum.

I always read the P_51 had a average roll rate at most speeds and that the P_40 had a very quick roll rate (due to stubby wings). Where did you read info on P_51 roll rate? This is a question not an argument.

Oleg - you wouldn't have a LINK to that discussion, would you?

This forum needs a search engine http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif

UCANFLY - I'll look for the material which cited the flight characteristics.

Uncany and GhostPony, you guys have a point.

Actualy the P-51 did not have a good roll rate at low speeds. It had an average roll rate at med speeds and it had a very good roll rate at high speeds.


Now i have actualy tested the Roll rate for the P-40 and P-51 at differant speeds and compared the data.

This is what i found.

Up to 600kmh TAS the P-40 has a better roll rate.

Once you get to about 650kmh TAS they bouth have about the same roll rate.

700kmh TAS and i shoot i forget what the differance was at this speed. Dmit i should have written it all down.

If i can find my results and find that chart i was looking at then that would be cool lol.

I dont think the P-40 should roll faster then the P-51 at 600kmh TAS. If i new where that chart was then i could see at what speed the P-51 started to have a better roll rate.

Oleg -

I do recall personal interviews with P-51 Pilots who fought in WWII, either by TV or CD/Video Tape. I recall they said the P-51 had real bad spin/stability characteristics WITH A FULL MAIN FUEL TANK. They would select the main tank at take-off, draining it down to about 40 gallons in order to correct the handling characteristics. (May have been Chuck Yeager who stated this)

Next time I view my CD's/Tapes... I post it.

I have read about the P-51 spins... by P-51 pilots, but no fuel quantities were mentioned.

Gp

Teh p40 had a great roll due to the design of it's alerons - which were hinged back of the leading edge - allowing it to protrude a bit above the surface of the wing into the roll - thereby grabbing air from the other side - increasing the aleron's life while easing the control effort. P51's roll was nothing to write home about - mediocre.

I get the impression that there's nothing wrong with the P-51 that we have in the game and I'm excited to fly some more P-51's. Every plane in the game isn't 100% "accurate" but since no two planes are ever the same anyways its pretty impossible to even expect perfect accuracy. I'd say the P-51 is a great fighter to fly in FB and I enjoy every moment in it!

I very much like the way the p51 handles - it is not my fav (too easy http://ubbxforums.ubi.com/infopop/emoticons/icon_smile.gif) but it surely does rock.

Actualy at low speeds it sucked but at high speed it was pretty good.

when you look at a roll chart youl notice that the P-51 will start to out roll the P-40 at a certain speed.



But to say the P-51 had a mediocre roll ate is incorrect, it had a better roll rate then alot of planes like the P-39, P40, and P-47 at high sdeed.
