G4M autoclimb/trim(?) bug - version B29 patch 1

[EskimoJoe]

I noticed while flying the G4M "Betty" today, that there seems to be
a very, very slight left handed drift while in auto-climb with Combat
Trim enabled. I have not tested this in level auto-pilot nor with
auto-climb with combat trim off.

It is very, very slight. It may be torque, but it may also be a bug.
I noticed while in auto-climb, that I always seemed to be a little bit
left of my target a period of time after turning nose-on, numerous times.

As a minimal test, I set my course heading west and put it into auto-climb.
I turned combat trim OFF and back ON again.
I waited at watched the compass. Very, very slowly it seemed to inch
southwards.

It may be part of the plane.

For example, certain 109s on auto climb have trouble handling a constant heading at high altitudes. The forces at work tilt the wings just a tad when WEP is used so that even with full trim you can't auto climb. You'll find similar issues where auto climb cannot compensate for the forces at work in a few planes, under specific circumstances.

I do notice the betty is squirrelly.. Goes back and forth on the ball when you make manuvers. Might just be she's settling into her auto pilot?

I have noticed what "feels" like a slight crabbing when in the bomb sight in the MA (MA, note no crosswind) but did not think much of it. Thought my dual throttles might have been 98%/100% respectively or something.

I use a single throttle and get the same feeling. Everything checks out with other aircraft
on my end, and the two previous times I flew the Betty (pre-2.23) I didn't seem to have
this... "problem". Albeit more of a strange "Am I trimmed right?" kind of feeling.

it drifts....

I took off NE - next thing I know I ended up going north (wasn't really paying attention)

I hate to bring a dead thread to life but it still does it.

It actually drifts on takeoff when you let auto takeoff do it. You're already going the wrong direction before you're wheels up.

i did some testing offline, and the higher up you go the worse it gets.

The typhoon and tempest probably do this the worst. Its torque from the engine. I found that if you increast the climb speed by 20 MPH or so, that they will climb straight and level. For the typhoon and tempest, I climb at 200 MPH, as you get a great climb rate and no slight turn from the engine.

if you put it on autopilot it eventually straightens out. it never goes off course once you have the torque under control and are flying level, you wont just fly off in the wrong direction. the betty never straightens out. so it never really does fly on your course that you put it on.

I know they wont go off course if flying level, I am talking about a climb. if you would have read my post, you would have known that. (though I menting Climb straight and level, that means in the climb they will not drift with the slight turn if you have a higher climb speed)

if your sitting at auto takeoff climb it will striaghten out after about 2-4k or so. if you climb at 160 you still get nothing but straight flying.

I dont use auto take off climb. thats why the planes have a slight turn from the torque, as I dont use it.

[MarineUS]

It does it for any auto climb.
