HS129 takeoff

[beresford]

How do you takeoff in this thing? I get it rolling in a straight line and then when I apply more power it swerves and ground loops. The rudder seems to have no authority and the toe brakes very little.

On the occasion I did get it into the air I noticed that the prop pitch control seems to be inverted.

She's a beautiful mallard duck that requires somewhat of a rudder dance on takeoff.  Requims video will show you some of the things I WASNT doing before.  Behind the 47, the 129 is my jam and have zero issues after watching the vid and following his steps.  Cheers.

I watch the Requiem vids and I tried unsuccessfully to duplicate his takeoff…. several times. What I saw elsewhere was that sometimes the autostart leaves the engines asymmetrical, so I'm going to check that next time.

This procedure always works for me 100%

 

pre-flight:

1) boost button on

2) manual prop pitch on

3) flaps down one level (ie. one button press)

4) center the rudder (precision important)

5) elevator up to press the tail down (precision important so no joystick left or right, only down)

 

takeoff-run:

1) push the throttle forward 100% while holding-down the brakes (there is one-button brake in this game for both left and right brakes)

2) release the brakes quickly (before they are overpowered)

3) watch if the plane veers left or right (sometimes it doesn't especially if your rudder is perfectly centered)

4) counter #3 first by stab on left or right brake, and then as the plane gathers speed by the rudder

Make sure that the mixture is set to REICH. The automated engine start-up procedure knocks it two-thirds of the way back from the fully forward ANLASSEN needed to start the engines.

It definitely takes some practice to get her going straight, you really gotta stab the rudder and not hold it down in either direction for too long, I usually just leave the auto RPM on and raise engine power slowly. Once it gets going though she starts straightening out. Just keep practicing.

Try to master combat take-off, it is more fun.

Thanks for the feedback, chaps. After a few failed attempts at the subtle method (it always starts to swerve halfway down the runway) I tried the unsubtle suggestion of briefly holding the wheelbrakes on and whacking the throttle to maximum and it WORKED. I don't think I even had boost on (with 60% fuel and a 30mm cannon).

Using brakes during the first phase (before you have rudder authority) is a key. It's due to opposite engines rotation.
