Crashing right after take-off (P51)

[Flying Cadet Mad]

I just go for instant action, increase throttle and before I am about to take to the skies, the plane tilts to the left so when I take off I crash almost immediately.
Joystick is fine, nothing should interfere with the game - any idea what is happening?

I have been playing flight sims since the Wright Brothers but never had anything like that happen to me :-(.

Hi. This is how it shoul'd behave. It is caused by torque,gyroscopic precession, slipstream and assymetric blade effect You have to counteract that by locking and pushing on tailwheel, adjusting ailerons and rudders. Check this video. This will explain you all you need to know.

Also you might just overpull stick. So aircraft instantly goes into stall.

In the settings for the game, under P-51D (and the other prop planes), there's an auto-rudder trim function that tries to automatically control your rudders while you are going down the runway. Sometimes you may under or over compensate for this when you go wheels off the runway and it can make it sloppy. Just keep that in mind or turn it off. I think it's even adjustable but I don't remember.

You are also supposed to set the Mustang's rudders to 5 degrees right for take off.

With that said, just keep practicing and you'll end up with perfect take offs.

Thanks for clearing that up - it did help me figure out what I did wrong.
Guess, flight sims are not all flight sims - this one is way closer to reality than most I have seen before.

If you are coming to DCS WWII from IL-2 BoX, you will be in for a bit of an adjustment.

It took me quite a while to realize that the problems is caused by not setting up my rudder pedals correctly (got them new) - in the default state, they act as throttle and acted against my actual throttle...
Still trying to get used to using a Warthog flightstick...

When you take off, there is a counterintuitive trick to keep the twisting effect at bay. Keep your nose down. It's not terribly more difficult that.
Raising the nose, or letting the nose climb multiplies that twisting effect. In fact, that nose climb is really the entryway for the twisting... you don't have to fight the twisting with rudder and aileron violently (still a good bit though), you just have to mainly fight the nose climb. If you keep your nose down until you are about 200 ft from the ground, the twisting subsides. If it's still stronger than you'd like, try pulling back on your RPM.
You don't need maximum speed to take off. So don't gun the throttle. And just fight the nose climb and you should hold steady.

When people take off unsteadily, they actually find this out and do it when they recover, they just may not be aware of it. They will spin, get extremely close to stall, then crawl out of the catastrophe very slow and shallow happy that the plane is under control.

Usually they spin because they pull stick too much. Just right after takeoff, reduce power to MPC, get some speed, then start climbing.

I just did this with the Bf-109, the most notorious takeoff spinner, I left RPM to auto, basically full, no change, and too late to stop, I realized my tail wheel was unlocked... absolutely no problem. Tap the right brake a couple of times, nose low, no problem. No overthinking. On landing, try to have such little downward descent rate so that your shocks absorb all of it, or you will bounce.

Read the manual. There is described the propper take-off procedure.

For take off with 51: No flaps, set rudder trim 4-6 degrees right and elevator trim 2-5 degrees nose heavy (depends on your load) . Pull stick a bit, this will lock the tailwheel. Set maximum RPM. On brakes, increase throttle to 30" and let it stabilise. Once stabilised, release brakes and slowly increase throttle to maximum MP. You will need to do just very low rudder inputs if you made all right. Once your speed reaches 100 mph, release the stick to let aircraft lift the tailwheel to air. Sometimes when you are too heavy and did not add enough nose heavy trim, you will need to help it by adding push on stick. Once your tailwheel lifts off, start gently pulling the stick until aircraft is airborne. Once airborne, reduce power to MCP-Maximum Continous Power setting- 46" MP, 2700 RPM. Always first reduce throttle, then RPM. Never do it opposite way. Same for increasing power, first add RPM, then add MP.
Level aircraft to let it get some speed, gears up, adjust trim.

Check that you have set auto-rudder off and take-off assist to value 0 in special options menu.

of course. first thing I turned off when I got it. There's literally nothing to it now.
