Hi,
After touchdown, as I am slowing down, as soon as my tailwheel touches the runway, I go into an uncontrollable right ground loop, and usually tear my wing off.
I couldnt find a key to lock my tail wheel. Am I missing something?
How do you stop a F4U?
-
Brendo, just before the tailwheel touches try "burying" it, pull back on the stick hard.
The hawg is very unstable at this point and the sooner you can force than wheel on the ground & regain rudder control the better.
-
To Land F4U's, I drop full flaps and float over runway. When speed hits about 90 and I am 5-10 ft above runway I kill engine to prevent torque from pulling her over. I use the right and left wheel brake to correct course and lay off the rudder.

I land it like any other plane! with the exception being....
When the nose starts to want to go right on you into the loop i just give it a little throttle, this straightens her out. You may have to do this once or twice as you are rolling out.

I just slow the plane below 100 mph with full flaps out before I touch the runway, turn the engine off and like the guys above say, SLAM the tail down and rudder that mother to prevent the ground loop. Use your wheel brakes too, they help a lot.
-
Ground loop happens when your tail wheel isnt actually on the ground, and you use your rudder. You need to get the wheel down to stop from spinning out.

Thanks guys. Flying my perked Corsair is terrifying.
I shall try these tips and hopefully not get 'eliminated' :D

I've been flying F4U-1s a lot lately and I've fallen into a few rules for landing/stopping. My landing speed in all aircraft is about 100 mph with full flaps. Just before I touch the runway I pull in my flaps to kill that extra lift and help to keep me on the runway. One thing you can do here is turn off the engine to help get rid of any torque, but I don't typically do this anymore. I roll down the runway and do not hit the spacebar (brakes) until my tail has dropped and I'm safely rolling on all three wheels. You do need some rudder input to keep yourself straight though, but take it easy with it.
-
Stay off the brakes untill you have slowed down considerably after touchdown.

PS....Retnuh still around?
PPS, the Blues are gonna get bit in game 2....and 3 , just you wait and see ;-)

Full flaps and flare into a 3 point landing, no need to cut the engine or use differential wheel brakes etc just get all wheels down together.
-
I fly the f4u a lot and I still have the occasional runway flipout on landing . If there is a CV around I'll try to land on it if possible instead of a dirt runway for this very reason . Take it very easy on the brakes, let it coast a bit before applying them . If you try to put the tail wheel on the ground going 100mph with flaps completely out the plane will come off of the ground again and you will bounce HARD . Also i don't use combat trim so I usually try to trim up for landing . That is auto trim level at about 110mph with flaps down all the way, gear down and throttle open a bit for torque .

Land a Hog? Hell, I never last long enough in a Hog to land one... :D
However, when I do get the chance, I just let the arrestor cables grab my hook and stop me. Honestly, I can't ever recall landing (or launching) a F4U at a ground field. weird, huh?
-
Are they available at land bases? :confused:

One thing I do to land a Hog (fly em quite a bit, land regularly on airfields vs CV's) is to use the ailerons while on the ground to keep it level. Don't use rudder at all on landing to level the plane. Give it just a little bit of aileron (roll) to correct until speed is something under 100 or so then use wheel brakes (c and v) to correct. When using the wheel brakes on the keyboard be sure to pump them vs holding them down for any length of time. Normally you would pump the left wheel brake about 3-5 times for every 1 pump on the right. Using this method I typically land at about 130 or less, never touch the rudder and don't have to slam the plane down. I also only use flaps to slow myself as I'm on approach, retracting flaps completely prior to wheels making contact to avoid the bounce. This is the only plane that I do this in, all others are pretty easily handled on the ground with rudder. As with all planes I normally come in flaps up and let it float itself down. This probably isnt anything like the real deal for a real landing but it works in here just fine. I do use the rudder on takeoff but that is it.

i just react to what the plane does...i auger alot on tocudown in this plane.

I used to have a terrible time landing F4U's untill figured this out, now no problemo :cool:

I fly the hog 90% of the time, and I land with full flaps, but keep forward pressure on the stick to keep the nose level at wheels down. On touchdown, I raise flaps, and gradually throttle down but keep an eye on propwash effects...the nose will raise eventually, and bu that time the plane is nearly at a standstill.
I land at any speed at or below 150, btw.
In any event, I prefer landing on carriers! Once you can land a hog, succeccfully, everything else is a piece of cake!

This is so easy yet you all come up with so many ways to make it hard :)
As yet another option :) on final approach flare into a nose high attitude and full flaps, control descent with throttle and speed with angle you should be able to do a controlled stall onto the runway putting all 3 wheels down at once without sufficient airspeed to bounce up and have full control as soon as you touch the tarmac and of course then bury that stick into full up to keep the wheel down.
-
Yep three point landing is best way to land corsair . My accidents happening while taxing :o
-
I'll try the 3 point thing y'all suggest. I don't think my way was so hard, I usually need to taxi to the hot pad anyway, and its easier to taxi when I can actually see where I am going :)
As for anything else, I'm always willing to go to the TA and learn from all you hot shot Hog jocks :)

I use a different approach to landing the hog. First I use all of the flaps but I drop them 1 stage at a time. Secondly and most important is that I trim the elevator all the way down. This causes one to have to slightly pull back on the stick to keep her nose up but once your down, your glued to the ramp unless you hard rudder or something. Engine can be running at idle for a power glide in to a three point landing using this method.
Trim to the all way down position for Elevator (max, nose down)
Flaps all way down in increments according to speed.
This combo will force you to pull nose up slightly.
whola, instant three point landing with no tendancy to spin.
Also make sure your rudder and aileron trim is set to neutral (since you are power gliding in).
The only way you will spin is if you slow down below to a very slow speed then shove the throttle to max again.
The reverse can be used for take offs as well except (no need for flaps except 1 notch when roling from CV) you have to trim up as you reach single engine speeds. Also wacking the throttle to full at 0mph before you get some air flowing over the control surfaces will cas a spin.

Neat thing about the f4u , it rest on the deck at a near stall angle of attack due to it's tall tail wheel .

I just go with the loop. I useually come out with no probs.
