b25 crash on take off - 95aqua-ta - 17.02.2010

Hi guys and gals,
I'm trying to play an offline DGen campaign with the B25J and I simply cannot get airbourne. You see at the start of the take off run it wants to veer left so I apply right rudder, it then straightens out but suddenly will swing wildly to the left and break it's undercarriage and crash. I even let the autopilot try to take off but that still manages to crash in a heap off the side of the runway.
How the hell am I supposed to get this thing off the ground? I mean it's only the first mission and I've crashed about six times already!!!!! :newmad:

Hi, make sure rudder trim isnt full right or left,
make sure both engines are sellected,
that you have take-off flaps down,
that prop pitch is 100%.
Most important... Dont slam the throttles to full power,
apply power slowly while holding a bit of right rudder,
when you hit about 80 mph go full power.
(If Im on a short strip I use landing flaps.. dont know if it s better but it seems like it is)
Hope that helps.

And DON'T lock the "tailwheel"!

I noticed that bug on several aircraft. if you don't have a tailwheel
but hit the "lock-key" for it, your plane becomes completely uncontrolable
on takeoff!

sounds like excessive side wind - Guest - 17.02.2010

this will cause those exact symptoms....

Select all engines? - mnlk999 - 17.02.2010

Have you tried that, sounds to me like one engine is out tourqing the other.

- 95aqua-ta - 17.02.2010

Thanks for the replies, firstly I did have flaps at take off and throttled up slowly to about 55% or so with no rudder trim, just using the rudder controls.
Both engines are selected and I even gave them a quick throttle check and monitored the gauges to make sure they're both responding the same.
I think however Vmax might have the answer in that I DID lock the tailwheel on an aircraft with tricycle gear so I will try that tomorrow as it's early morning here now, so with that I'll say goodnight and thank you.

And increase power smoothly. Don't push the throttle at 100% before being at about 20mp/h or the aircraft isn't stable at all.
The nose gear hasn't any anti-shimy system and you need enought speed to permit the nose gear going straight or it's the engines that will take control and as the propellers as going around the same way your aircraft will tend to go left (same with the P-39/P-400 indeed). I haven't tried with the A-20.

tater,
I actually had the same problem with the P38 two nights ago, and was wondering how I effed up taking off in a bird I fly alot. I had just recently tied the "Lock Tailwheel" control command to one of my CH throttle buttons...so I bet you that I hit that switch without thinking. So vmax and pilotsden, thanks for that tip. This is why I like browsing through these threads...you never know what surprise information you'll find!

- 95aqua-ta - 18.02.2010

Well the Tailwheel lock was the culprit!
Without it the aircraft took off easily, although I can't hit a damned thing...lol
One question though, is it possible to just be the bomb aimer? since trying to line up on a target that you can't see from the cockpit,then going to the bomb sight and setting up all the parameters and adjustments to hit the target is very difficult, especially as the bomb runs tend to be quite short.

- RedrumSalad - 19.02.2010

set a key to level stabilizer, line up the plane with the target, press that button, then go to the bombardier, and there ya go
