Can anybody assist me? I am trying to fly the Vickers Vimy with Alcock & Brown and it's impossible to exceed IAS 55 and climb more than 50 to 100 fpm. I need more power to get up to anything resembling their real speed of 120 mph average. Is there some factor I can tweak in the cfg file ?Also, the ailerons and rudder are almost hopeless. They work, but they over-react and put one into a tight turn from which it is very difficult to straighten out. I am currently at 2000 MSL at IAS 55, 16 nm out of Newfoundland to Ireland. I'll never make it at this rate.Appreciate any posts, thanks!JS

Probably not what you wanted to hear, but I hope you packed a lifejacket :)

Nope!I was expecting a lot more power'n lift ! (Ha!)JS

Where are you taking off from? If you are trying to fly from somewhere which is high in altitude, then with the air being thinner it will have quite an adverse effect on the engine. Try finding an airfield at sea level and going through your take off sequence again. This is something that was found when doing the review for Fs2004 when it was first released.RgdsAidihttp://www.vfr-flightcenter.com/avsim_sig.jpg

50-100fpm is a quite decent climbrate for the Vimmy, you're lucky to get even that sometimes (depending on wind and altitude, as well as fuel load).55 knots indicated translates to about 80 mph, which at full tanks should be about the max you can expect.As you get lighter, you'll get faster.

Gentlemen:Well, thank you kindly sir. I wondered if the plane was "sagging" a bit because of the huge fuel load. Presumably I'll have to fly for several hours before I can get above 2500 feet MSL and IAS 55 then. So I shall chug on. I did save the file at intervals so I can go back and continue.The story of Alcock & Brown is simply fantastic. I never appreciated what hell they braved and what terrors they faced. Check out this link if you haven't done so already. It makes me feel like a sissy flying the 747-400 with an FMC!http://www.aviation-history.com/airmen/alcock.htmThanks for your post.JS

Besides, the Vimy's airspeed gauge reads MPH, so he's doing 55mph.Can't help the original poster, I've never flown it before.

Actually, I always fly with the red MSFS GPS readout on and it indicates 53 to 57 IAS. The speedo reads something over 60. It is horribly slow, I must say, but it is at least some way above the stall speed (!) Nonetheless, I had expected to be able to fly at a steady 80 to 90 mph, even when very heavy; and also climb at at least 200 fpm. I think that various prop a/c are way underpowered in FS2004.JS

I just did a quick flight in it now, I was able to get it up to 80mph (~70kts).

Flying the Vimy seems to be an object lesson in drag management - no excessive yaw, no excessive pitch or attitude, and no to putting the nose down to increase speed for a zoom climb (too much induced drag as soon as you try to pull the nose up again). Given the technology of the day, and the power to weight ratio, I have no reason to doubt that this is anything other than the way it is/was. I just have no idea why somebody would conclude from this experience that all a/c are underpowered in FS. How much time do they have in a Vimy to enable them to offer that assessment? Read the accounts of the reproduction Vimy flight to Egypt lately?If you read accounts of the A & B flight you will find that they had to consider the weather as the prime factor - in particular the winds. The aircraft was dramatically overloaded at take-off and would therefoe remain so much of the way across.Allcott

I don't know if this is any use or not but when I purchased FS9 I installed it in my then current computer (Celeron 900 processor) and everything was underpowered, and it took twice as long as it should have to get even the B737 airborne. After trying my son's laptop (P4 1.6) it worked properly so I bought a new computer and all was OK.So what I'm saying is that an underpowered system might have the bad effect of low power. Of course, I don't know what your system is.

Here is some info from the LearningCenter in Fsim.FSwebLearningCenter-----------"The Vimy is a massive airplane for the size of its control surfaces. Keep in mind that when you want to maneuver, there is a delay between pilot input and airplane response. For example, if you're correcting direction on the ground, you put in some rudder and wait, but then release the rudder before the airplane starts turning

Jim:Were you flying with full tanks? At what altitude did you attain 80 mph? And were you level or climbing ?JS

Allcott:I was not saying that ALL a/c are underpowered in FS9. But some of the prop a/c are.It would've been helpful if MS could have included some description about what flight performance one could expect in a/c such as the Vimy. It's not as if we fly these ancient crates all the time. Given my experience so far, I posted because I wondered if there was any way to get this machine to go faster. A&B averaged 120 mph all the way over, admittedly with a tailwind. But even if the wind were 50 mph, that still means an average of 70 mph. And they climbed to almost 12,000' at the peak although again that was late in the flight.I do think that MS could have engineered some of the props better and should have included some more basic info on flight performance.JS

Kurt:This is very interesting information. Now I don't feel quite so bad -- although my speed remains pitiful. Thanks for posting ! JS
