Spit VB Takeoff

[beresford]

I have full right yaw trim and it still veers left, even with max right rudder. What am I missing?

So, this is likely an abuse of the problems in the current flight model, but for a super easy Spitfire take off, deploy landing flaps, pull the stick all the way back and set the throttle to 100%. You will take off with almost no rudder inputs needed in a very short distance.

It looks a little silly, but it works fine.

That is pretty much the description of a take-off from a carrier - but with the flaps held only partly open with wooden blocks.

You may be opening the throttle too much and/or too fast.  In normal take-offs put the rpm fully forwards (max) but open the throttle slowly: do not use maximum throttle/boost. Spitfire IX manual recommends only +7 to +9lbs on take off.  Do this and you should find that only dabs of rudder are needed even with no rudder trim. Also, do not try to force the tail up - it will rise naturally, but jerking it up with the elevator will also induce yaw.

I just tried this... and a normal take off is easier...

Strange. I find my method far, far quicker and easier.

That's good to hear.

I'd love to know your source.

I think a lot of it depends on the peripherals you've got & how you've got them set up. Before I got my rudder pedals I had a devil of a time getting the spit off the ground. Now it always looks bloody ugly but she usually gets airborne. I'd also agree with the points made above about setting RPM before the roll and then increasing throttle more slowly than you would in other aircraft...

 

 

As i mentioned in a previous thread, a constant stream of under-the-breath profanity usually helps too...

1. Apply a little throttle to get you rolling straight for a few seconds.
 

2. With full right rudder and stick fully back, smoothly apply full throttle (over about 4 or 5 seconds).

     This will give you better airflow over the rudder quickly, which will give you better control.
     You may find that you need to reduce right rudder slightly to keep tracking straight.
 

3. Immediately correct any left or right turning tendency with quick stabs at the rudder pedal.
    It's very important to correct turns early. If you leave it too long, it's very hard to get back on track.
    Do not apply continuous rudder inputs to correct turns.

 

4. Once you get up to a speed where the rudder is effective, smoothly move the stick just aft of neutral and let the tail come up on its own.

There are a few sources for this I've read one recently under Scramble: the dramatic story of a young fighter pilots experiences - Tom Neil.
though it should be noted that they did this because the deck had a bulge in it (early ski jump) and the hurricanes couldn't quite get to speed before they hit the bump and went up in the air.

Made this just for you.

Seafire 45 46  manual mentions that the flaps have a manual setting of 18 degrees with spring loaded pins or on earlier aircraft wooden blocks. The blocks were then dropped out after takeoff by lowering then raising the flaps.  Obviously on a very short deck you need to accelerate fast, but the manual does not give exact descriptions of carrier take off techniques, unfortunately.  I had another description of carrier take offs in Spitfires somewhere, when they were being ferried to Malta, but it is buried somewhere in the hundreds of magazines and books....

Operation Pedestal, August 1943.

 

Wood wedge are a add-hoc solution for Spitfire take of from carrier.

 

 

" The departure of Furious was delayed by technical difficulties caused by the flight deck, that sloped upwards to a point amidships. A Spitfire made a practice take-off, with wooden wedges in the flaps to ensure a 25° angle and Furious steaming at 30 knots (35 mph), into a 10 kn (12 mph) wind. "

http://spitfiresite.com/2010/04/1942-defence-of-malta.html#targetText=A simple solution was developed,then close the flaps again.

 

 

BTW - Take off with BoK Spitfire VB is very easy, don't need "cheats", alias if want don't need even touch the stick, just use rudder, throttle and trim.

Thanks for the help, guys. My problem was RPM, I have half-page crib sheets for every a/c with the keys and important gauge locations and T/O/landing speeds, and for some reason I had RPM down as 'Auto'. If you take off with RPM manually set to 100% you don't even need rudder trim as per the Requiem vids, you can get away with slight rudder correction during the takeoff roll. I am using an old MS Sidewinder (so old that the rugous coating has degenerated into glue).

I mean for the full elevator deflection.

[RNAS10_Oliver]

Yeh I figured that was rather the part you were on about. But just adding another source for the use of wedges like the others. Am also interested to know the source for launching from carriers in that manner. Not something I paticularly remember reading about nor seeing in videos.
