P-38 problems?
« Reply #15 on: June 10, 2004, 10:26:33 AM »
P-38 Test

Online
Calibrated
Wind is 9
Altitude 0

1) I observe a pull to the right or left depending on the wind direction.  

2) Pull is present without engine on when rolling.

Does 9mph push that hard on takeoff?

At low speed the P38 in AH2 has torque and pulls from side to side like mad.

Is this on purpose?

I got the same thing ... 38 pulling left ... thought it was my stick.....  I didn't check wind .. will next time i'm in there...

But stick was fine- i was looking at ah indicator .. rudder was centered...

Though, 38 seems to handle fine in the air to me....

Pyro, it's kinda hard to center the trim indicators for a couple reasons...

1) There is no centering mark
2) Either CT or auto-takeoff has the aircraft trimmed for you before takeoff regardless of whether or not you have either one on. To boot, the trim is in both the wrong direction and the wrong amount. A long reported bug that's never been fixed.
3) There is no indication of how many degrees of trim is available
4) There are no markings to indicate how many degrees of trim you put in

If it's in the middle, it's centered.  Doesn't matter which way or how many degrees it goes.  I know the torque and slipstream effects of the two engines are canceling each other because when I run through the combat trim learner, only the elevator trim receives any input.  However, I did find a problem below 150 where the combat trim settings needed to be manually cleaned up because the function that sets the combat trim settings doesn't work at those low speeds.  That would cause the bug that you're talking about with the starting trim being off as that affects starting trim whether you have CT on or not.

I'm still somewhat perplexed by the reports of the change in the 38's characteristics during the beta.  I did make a change that made it's stall behavior a bit more docile.  This means you can pull into a pretty deep stall before it wants to drop a wing.  It could be that people are pulling too deep into the stall rather than riding the peak.  The only other thing I can think of is higher fuel loading.

Docile? Its horrible! The P38 flies more like a Me110 does now, makes no sense to me what so ever.

Get below 150 and turn with it, flaps or not, she flops around like a fish, or akin to an aircraft with torque.

on P-38 turning
« Reply #23 on: June 11, 2004, 06:56:14 PM »
before some of you guys go off the deep end thinking the 38 is preforming odd let me explain a few things as i see them....

say you have a p38 vs a spit V ...

is the p38 going to outturn the spit ..... who know's.... can it?  

maybe, it's very close.

with a light fuel loading and in the vertical the 38 turns on a dime with it's flaps extended .....

but keep in mind ....

if you nose down ... the 38 is very heavy ... it's has two powerful engines .... it's downward tendancey is going to make you speed up much faster than the spit you are fighting ....

reverseing such momentum can be harder for you, you'll feel this if you nose over full thottle then try to pull up hard ... gravity, and your mommentm and wieght make this hard to counter, flaps help .. but don't expect this turn to be as easy as a vertical turn for the 38....espesially if your hitting full thorttle ..

a flat sideways turn can be very tight ... but you have to lose your speed and get your flaps out in the 38 ... or your momentum will carry you into a stall...

if you push into the stall too hard the p38 will become less stable ... as you push harder you can fully stall it,  the key is slowing down enough to do two things .... avoid the stall  by haveing less forward mometum... and get your flaps out to 'lift' you into the turn ... and further slow you off your orginal path ....

cause things like to stay on the path they are heading .... and the more speed ... the greater this effect, looked at simply.

the 38 is hard to understand .... I think some of these feelings may come from misunderstanding the situation.  The 38's FM feels fine to me.

All sounds right to me, Mane, have you flown the  beta 42 patch yet to see if there is any difference?  I myself didn't have much negatism toward the 38 characteristics in last 10 or so patches.

I always understood to fly/fight with  the 38 in the vertical, as I think Slap said in another thread,  use the vertical and it's ability to hang on prop/ stall flight.  not turn fight.
