Take off Crash problem

[SketchFrenk]

Hello,

I am playing DCS for about a week now and I am using a Logitech Saitek X52 Hotas. I am trying to fly the T-51 Mustang that comes with the free DLC.

My first attempts at take off were oke. When gaining sufficient speed the plane would take off but since yesterday I am having serious issues.

I followed some tutorials about correct engine start, taxi and take off. I follow all of these steps correctly including setting the rudder trim to 5 degrees. When I am on the runway, holding brake and gently increase the throttle an release brake, it rolls down the runway as usual. But when I am at a speed of about 100 mph the plane suddenly takes off and rolls down to the left resulting in a fast crash. This has happened every time I try to take off since, even when I use the auto start procedure.

All of the assisst are turned off in the main setting menu by the way.

What am I doing wrong here?

Same happened to me when I was in the same learning phase years ago and just forgot to raise flaps from full down position after cold start.

It's difficult to say, however, from description only what might be going on during your attempts. When you exit the mission hit Save Track button and post it replay file here so that we can take a look and advise.

It sounds like youre pulling to hard.

if you start rolling, keep stick back to lock tailwheel.

if you start your roll and youre about to reach 100mph center the stick gradually.

the snap roll happens because you stall your plane.

@Doughguy I would not hold aft stick until 100mph in TF-51, this one lifts off at 90mph. TF-51 much lighter.

@SketchFrenk I would try to apply a little bit stick forward but not too much, to gain 110-120 and then slowly pull it back. like @Art-J siad your description doesn't provide any particular information other then, you could take off yesterday and now you can't. It could be controls problem, it could be wrong configuration for take off, and  many other things.

But my first though is that you are lift stalling this TF-51, so go easier on stick during take off.

 I also had this problem.  I have X-52pro and Thrstmaster T-flight pedals.  I have the brakes bound to the toe brakes on the rudders.  When I used the RightCTRL ENTER to show the control readout overlay, it was showing that one of my brake pedals was staying stuck at about 20% on.  I used the on/off switch on the USB adapter, made sure the pedal was calibrated by the devices and printers menu, and kept my feet off of the pedals until after the plane spawned in.  That seemed to fix the issue for me.

Have you set the toe brakes as sliders?

I haven't touched the axis curves settings.  The calibration app in the Devices and printers desktop window was also showing that one of the brake pedals wasn't going full-range until I unplugged and re-plugged the pedals.  It was definitely a problem with the device, not the game.  The pedals work fine now but, does setting as a slider allow finer control?  If so, that would be great.

Every control without a center is a slider. Throttle, collective, brakes, illumination dials etc. That goes from 0 to 100. Your stick/cyclic and rudder/torque pedals have center, and are not sliders and have positive and negative values.
Finer control? I have no idea, I just want every control to be setup correctly, and I don't use curves on any of my controls either.
BTW. In some modules, the toe brakes also need to be inverted.

Cheers!

Edit: I just noticed that you have the T.Flight pedals. Yeah, sometimes I had to disconnect/reconnect sometimes to get the full range, but never with the pedals. Mine were connected through a TWCS. To get finer control, I "lubed" them with Nyogel 767, a real mess. But good. For helicopters I removed the single spring. It's a lid on the underside, and with some practice, so can remove/replace in seconds. There are 3D print files out there to make them wider too. The brakes were always hard to get right...

Thank you!  I will go into the axis tuning settings and set these as sliders instead of the default. 

Thank you for the advice on the pedals as well.   

 

For the point of the original post:  Use Right CTRL+Enter to bring up the Input Overlay in-game and make sure none of your controls are off-calibration or stuck as this could cause a problem during takeoff or other times during the flight.
