How come my B25 always pulls to the left during take off?

It doesn't do this in flight.

I just bought the game a day ago, and I am pretty much am doing ok with everything else (flown bombers only). Other than I need alot of practice on formation flying.

I have my flaps in take off position, rear wheel brake locked and gradually increasing throttle to both engines. No matter what, I am fighting it. I tried to watch the auto pilot take off... and it doesn't pull at all. What am I missing??

hello, from what you have described it sounds a lot like Torque. You might want to go to www.airwarfare.com (http://www.airwarfare.com) and read the tutorials there about complex engine management etc. Just put in some opposite rudder before you advance the throttles and adjust as needed on your roll out.

Its simulated torgue and "P" factor.

Ok.. I will try to give it a little more rudder. I did read the complex engine management. Though, I think I am still a bit confused. Since, I thought the torque on both engines would be the same. But, sure enough.. it pulls very hard to the left as soon as I start moving. I was thinking I may need to trim it a bit.

Also, what is "P"?

if you read this thread you'll probably find the answer to your problem.

I was having trouble with the B-25 take off as well and a lot of the guys here helped me out and it's all in there.

try selecting a fuel load less than 100% and don't lock the tail wheel when taking off.

I know I know it is the nose whheel but it still gave me a good laugh.

lmao, I know... but when you push your assigned button in the B-25 it actually says tailwheel: locked or unlocked http://forums.ubi.com/images/smilies/touche.gif

if the B25 had contra-rotating engines (i do not know if it did in real life or not) it should not pull unless you have asymmetrical throttle settings

however i think there may be a limitation in the game engine which means twins will still pull one way even if hey shouldnt

I thought that too until yesterday when Tooz pointed it out to me. Both B-25 engines rotated in the same direction and so the aircraft did indeed suffer from engine torque.

From the info I've gleaned the reason was to make it easier to repair the engines. The parts were interchangeable and only parts for one kind of engine need be stocked.

Yup the P-38 is the only plane in the sim with contra-rotating props.

Thanks all for you response.

I an unable to change the fuel from %100 in campaign mode. It is just grayed out. But, I did adjust the trim on my flaps before take off. It still pulls, but much easier to correct now.

If you think taking off from an airfeild is tricky try doing it with an aircraft carrier with 2000lb of bombs on board!

I had the same problem until I noticed only ONE throttle lever moving in the virtual cockpit. Make sure you select one engine and push throttle, then select the other and push throttle. Then take-off.

And Do-335.

D'oh!!! *slaps forehead*

Stuck on the idea of multiple engines on wings, not on the fuselage.

In campaign mode it won't let you adjust fuel or ordnance until you're the flight leader. You're just a rookie! You don't get to make those decisions yet! Now, get back in formation!

S!

Its Counter Rotating Props not Contra Rotating Props

Contra Rotating Props are two props turning in opposite directions on concentric shafts on one powerplant like the TU-95 Bear bomber.

Counter Rotating Props includes one left hand and one right hand rotation prop like the P-38 except for RAF P-38's & some built under the French/British contract used for training by the USAAC which had right-handed Allison engines.
