Typhoon question
« on: August 21, 2010, 12:09:50 PM »
I am curious as to whether or not the Typhoon is modeled correctly. Specifically the amount of propeller torque. I realize that when stopped or during takeoff the torque effect can be huge, but it seems to me that in the game it's a little much. 
During climb out at say 135 / 150 mph with heading and climb hold on, it still turns to the right. Look out at the right aileron and it seems all the way down. I would think this left hand turn position of the aileron should correct the torque (along with rudder input) but it doesn't.
Anyone know?

The short answer is it's modeled correctly.

Here's the take-off procedure from the IA & IB pilots notes;


Also in the book "A Soldier in the Cockpit" Ron Pottinger talks about his time flying Typhoons during the war and he mentions having to use almost full rudder on takeoff.

thanks Baumer
This info would lead me to believe that, although the Typhoon generated a lot of torque, it was controlable. Did your book say that the airplane would still turn right even with flight control correction? ie. left aileron and rudder.

Its simple to correct. Just level off and build up more speed before hitting alt-x to auto-climb. The problem is you are depending upon auto-takeoff which gets you airborne sooner and easier I suppose but at a slower speed then the best climb speed.

That's true and that is what I do. But I was still wondering if the auto-takeoff speed shouldn't be effective enough for the aileron and rudder input to counter act the torque.

The auto-takeoff of every aircraft is lower airspeed then default climb speed. Just takeoff manually.

This is due to how the "auto" functions operate I believe. If I have understood past descriptions the control trim is read from a table of speeds so if you're flying at a speed that's not the same as the table you may "drift" due to being slightly out of trim.

In my simpit I have extremely sensitive potentiometers for my trim control, and I have no problems flying the Typhoon hands off, keeping a constant heading.

 Baum,

 Not to correct you but,(ii) clearly states"open engine to 2500 rpm,then clean oil off windscreen"!

  I dont think HTC has that modeled,so I wouldn't say it's 100% correct...... :rofl :rofl :rofl


 TBH,it's been awhile since I've flown the Tyffie,maybe after the latest update this was addressed.... :devil

This.  Just build more speed before you hit auto-climb.

Previously, the trim tables for the Typhoon and Tempest were incorrect. The aircraft would slowly turn to the right as the Combat Trim wasn't applying enough leftward aileron trim at any speed. However, I thought that had been fixed.

I got a question about both the Typhoon and the Tempest. At just over 500 mph in a dive both planes automatically start to pull up. Less than that speed for the Typhoon. I can get a P-51D up to 540mph in a dive and pull out of it. With prop control I can keep it a 400mph for half a sector with out wep. In the off line area I like to see how fast a plane can go in a dive without failure of some type. Is there a trick to the Tempest to stop it from pulling up at 500+ mph?

I use a cruise climb of 200mph. Seems to maintain heading at that speed.  :)

dot speed 200 works well for the typhoon

You can use your elevator trim keys: I and K. A little practice usually does the trick.

Its easier to avoid this problem if you use manual trim. You wont actually avoid the problem but you will be trimming as the transition occurs.
