Ok this is a very n00b question from someone who started playing IL2 when the first demo was out:

Some of the early crap planes (and a few others) act really wierd on take off.
The worst example is the B-239 which lift its left wing violently at aprox. 75 km/h and drops it just as violent at 110 km/h. This is only happening during take off.
For the longest time I always crashed on take off flying the B-239, but at last I learned exactly when to start counter it, and now I can take off all right but not in a bretty fashion. The same thing aply to the I-153 but in a less marked degree.

I would like to know how to prevent the plane from acting up like this. I've tried different settings for prop-pitch, engine power, flaps, but I stil haven't found a solution.
I believe there must be a way to take off in a nice way, else all pilots would have crashed the first time they tried out this plane.

BUMP!

I'd like to know too, especially for the Brewster which seems like a complete pig on take-off.

I trim this plane before take off to counter the torque.
About 12-15 'taps' of the right rudder trim key.
About 4-5 'taps' of left aileron trim (B239 is one of the few planes that seems to have aileron trim now; in il2 most allied planes had it).
Apply take-off flaps for stability and lift (I don't use elevator trim as a substitute as the plane tends to want to roll into a spin).
I increase throttle very gently, and stop at about 60% or less; the plane should still eventually get up to take-off speed no problem.
As soon as I'm in the air I reset everything and trim it for flight a bit later.
Doing this, I hardly have to touch the stick during take-off; maybe a small rudder adjustment.
I use similar settings for any light plane with a powerful engine (Eg. I153 and I16).

Hope this helps.

The best (most consistently successful) way I've found on any overly-responsive aircraft is to line up on the runway and use the whole thing to accelerate more slowly instead of the "balls-to-the-wall" method so common.

A more elongated take-off routine has less of the radical torque effect.

I agree, she's a pig on take-off, but I've never had trouble taking off...just gotta be gentle with her.

As boltie said; U can accelerate slower.
If u are in a hurry u just apply full aileron in the opposite direction before it happens and u will be fine.

it seems to be affected by the aircrafts weight becuase the gravity of the game is way off. If you remember the early 190 fm it had ground stability similiar to the p47

Lighter aircraft will tip on one wheel and jump 20 feet off the ground when rolling on grass and others like the tb3 p40 spit hurri will instantly nose over if you dont have full back pressure applied to the elevator.

Even when using 10-30 trottle with rudder use your plane will drag a wing.

the width of the gears has no effect for ground stabily in fb 190 ground handling vs p47 for instance.

Im sure they will correct this for PF with carrier landings and manuevering but it need to be corrected in FB/AEP as well. Thats another reason why PF should be an addon for fb/aep to correct certain game engine flaws.

slower trottle and 0 trottle when turning helps but its not the solution. You get use to 110 trottle pretty easily since there is no torque effect and dragging a wing does not seem to cause any damage.

Thanks for the help all. I admit I've got into the habit of firewalling the throttle and no flaps until the speed's up on DF servers. Guess I need to treat this bird with a bit more respect.

The most difficult plane for me to get off the runway is an I-153 loaded with bombs. When that left wing rises, the right wing dips, and as soon as it hits the ground, BOOM! Someone's gotta hose off the strip. The only way I can consistently get off the ground is to accelerate slowly, as has already been said, and to push the stick a bit forward so the tail rises earlier. That seems to lessen the lifting of the wing considerably.

Ah, the Brewster. I remember having the same problem as well. It took me quite a while to figure out how to perform a clean take-off in her. I don't know about all those trim settings, because I found that as long as you kept the throttle under 60% until you reached a speed of 100kph; then continue to throttle up; I was a-okay in terms of stability.

Hope you like flying her, she is a real death machine in capable hands... and someday I'll be one of those people with the "capable hands" lol.

Cheers,

Thanks for all your help guys. I tried the takeoff with only 60% throttle and it worked a lot better (guess I only tested it down to some 75% earlier http://ubbxforums.ubi.com/images/smiley/35.gif)
And to Spookyruben: Yes I really enjoy the Brewster, in fact she's somewhat my favourite plane along with her I-16 counterpart. http://ubbxforums.ubi.com/images/smiley/16x16_smiley-tongue.gif

On a related note: I've never noticed one bit of difference on any plane with the tailwheel locked or unlocked. Now maybe there is a difference, but it's so slight that it makes no difference to me.
