Boy this is a frustrating thread to read through.

I’ve been teaching folks to fly almost exclusively on Kadet LT 40s for over 6 years now. NEVER had one that was squirrelly on take off OR took a whole runway to take off from.

Torque on a LT 40, regardless of engine size is not a problem. Yes, I’ve even taught on ones that had ST .91’s up front, they all fly the same. Yawing to the right due to P factor is just not a problem with that huge fin and rudder.

First, as the earlier post said make sure the rudder and nose wheel are doing the same thing. If it’s flying straight in flight then it should roll strait on landing WITHOUT you having to correct for it. If not leave the rudder alone and adjust the nose wheel linkages till it rolls straight too.

And as an earlier post mentioned you want to do what full-scale pilots call a soft field take off. Long before flying speed you’re going to lift the nose wheel off the ground and steer with only the rudder while you’re on the ground.

To do this; park the airplane out on the runway at idle, pointing into the wind.

Hold ½ to 1/3 UP elevator on your stick.

Go to FULL throttle on a three count, at a normal pace count one…two…three while advancing the throttle. You should hit full throttle at the end of three. Why do this? I don’t recommend partial throttle takeoffs because it introduces a lot of variables in what is happening. I’ve seen low powered Kadets just barely wallow into the air, on the verge of crashing because the student stopped pushing up the throttle too soon. Also if an engine is going to quit it will do it during throttle up so lets get past this problem too by being at full throttle. Thirdly the airplane will always handle the same at full throttle, partial throttle settings may not be the same on every flight.

Let the airplane accelerate until the nose wheel lifts off the runway or is just visible over the top of the grass. Now adjust your elevator input to hold the wheel there.

We now have the airplane at a positive angle of attack, rolling along on just the mains, accelerating to lift off speed.

Gently steer with the rudder as needed.

In less than 4 seconds the plane will lift off. You will need to reduce the amount of up elevator you are holding so that the airplane holds the same climb out angle that it had in the grass. Usually if you hold the amount that gets the nose wheel up, it will be too much after you lift off resulting in a very steep climb, possibly a stall.

All this takes about 7 seconds and no more than 100 feet even in grass.

Oh one last though are the main wheels still pointed straight ahead? If not gently rebend the main gear wires so that they are.
