....^^^^^.... Roll Eyes... Wink...

Now you can see why I love my little (nose-wheely!) Cessna 150/152 "Trainesr"!..... Smiley.....!

It does exactly what it says on the Fuselage!... Smiley...!

Tail-draggers have a mind all of their own!...(Ground Loops, etc).... Shocked...!

It takes a lot of training and practice, to safely control a small General Aviation tail-dragger aircraft.
Noting the wind direction is all important for ground manoeuvring, and take-off + landing !

Paul....FS 2004... Smiley...!

Only if you are a raw beginner with no idea of what you're doing. Tongue

Maybe in Real Life. Under FS not really. Before I understood the mechanics of it, I could only loop all the way to ever-circular hell or go straight into a word of hurt with the Cub and other similar planes... but once I read a sadly forgotten really well written page on the net about WHAT to do and WHY... I got better.

Not suddenly perfect, this I grant you, but I was able to make something else than disasters or donuts almost immediately, and in a half a hour of practice I could taxi the Cub with relative precision, if not ease.

Easy is not the way of the Force... nor the way of the Taildraggers either, and yes, the nosewheel-ed planes are by far easier, but there's a deep sense of satisfaction in being able to make a castor wheel taildragger do exactly what you want, and not what it whishes. A satisfaction only those who CAN DO it, can understand. Wink

.... Grin....!

One of the few benefits I have found with tail-draggers, is that they can mostly take off and land on remote, rough surfaces, which would most likely cause the nose-wheel to be damaged, or snap-off, damaging the propeller, and shock-loading the engine, on a tricycle aircraft...

...beware Gopher/Rabbit holes!... Shocked...!

...but ground manoeuvring a small, light, tail-dragger, in gusty, windy, conditions, is a work of art!....and a bum-clencher!*... Grin...!

"On a wing and a prayer"....The "prayer" bit applies to tail-draggers... Wink... Grin...!

Paul... Cool...!

* ....a bit like high-speed cornering on my motor bike!... Shocked...!

Hello All,

I am back to tell you that I could finally make some kind of "safe" take off with the piper cub, but honestly could not stay in line with the Runway. In my previous attempts to take off with that bird, I expected a take off speed above 60 or 70 Knots. Weel it seems that it is the cruise speed. This may explain my problem to fly with it. My "victorious " take off happened at a little 45 or 47 knots and the roll on back was not far anyway.


Thank to all of you for your precious recommendation.

Jeff.

Oh dear... Grin ...the Cub is quite the kite. A take off between 60 or 70 is DC3 territory. Just another kind of taildragger. Wink

Nice job !

Will try to do reproduce such clean take-off. Hum, it may require sometime !

Couldn't believe that a takeoff in a real Piper J3 Cub could possibly be as difficult as the one in FS9. Checked with a pilot who has J3 Cub time and he said, "If they were that tough, the weeds alongside the runway would have been littered with them still."

With that in mind I did some experimenting. First I went to the 'Aircraft, Realism' tab. My 'Flight model' settings are all sliders to 'Realistic.'

Setting the Torque and P-factor sliders to approximately 20% made a successful takeoff with the J3 Cub much easier and more certain.

Then I tried changing the 'aircraft.cfg' file in the 'Piper_J3Cub' folder as follows:

On the following lines, change the value from =0.3 to =0.05 on both lines. This is a good starting point and you can adjust up or down from here.

p_factor_on_yaw          = 0.3
torque_on_roll           = 0.3

so they look like this:

p_factor_on_yaw          = 0.05
torque_on_roll           = 0.05

Save, then close the file.

This gives you a Cub with flight characteristics closer to the real thing IMHO and you can leave your  'Flight model' tab 'Torque and P-factor' sliders at your usual settings.
