Bouncy Landings.

Hi All,
Does anyone have any tips for good warbird landings...every time (practise I know already).

I have a good few years experience with all types of airframes (large and small).

However, I have a 'P51' that weighs in around 20lb at 76'' and I seem to get 1 in every 4 or so landings frustratingly wrong - with the dreaded 'bounce', and am coming to my wits end.

I have tried tried both rolling in hot, and 'near stall' 3 pointers.
Both can be very pleasing, but every so often they turn into a near disaster due to the dreaded bounce.

Any Tips or idea's would be appreciated.

Thanks.

The lower the rate of descent the less the bounce. Plus you need to flare at the right air speed or it'll keep flying, hence the bounce or two or three.

Re: Bouncy Landings.

ive been training a lot of people this year.
i look over at a lot of them and they just start stressing on landing and try to force it.
i tell them,
just relax and FLY the plane across the ground at one or two inches at idle, eventually it will land its self.
dont think of it as a landing, think of it as flying low and slow.
its just like taking a dump, just let it happen...........

Re: Bouncy Landings.

As others have said above.

I have a P-51 that will bounce if I try to force it down too soon. On landing, I fly it straight and level at 2-3 feet off the ground idling or near idle and basically don't touch the elevator and let it sink in on its own. Mine has flaps and if they are deployed barn door style, it takes a bit of throttle all the way to the ground but the landings are very short (for a P-51 anyway).

Recently, I've been teaching a buddy to fly his trainer (Avistar) and strangely, I find that I have to fly that plane the same or it will float forever and bounce several times on landing.

Re: Bouncy Landings.

As said above, level your plane half a wingspan above the ground. At this height your plane is in the so called ground effect. This is a height at which the wing is more performant .Than throttle back and hold the plane off. The most important is that you learn to know your plane and it's behaviour.
Good luck with the landings and impacts...

Re: Bouncy Landings.

if the plane isn't a tippy rock... I will reveal the secret to you now.....

I once had a T6.... they are the "Auto-Bouncer" for sure....

the way to avoid a bounced landing is to touch the tail wheel first....

if you are flying at a speed so that the plane is at an AOA high enuff to have the tail wheel just an inch or two lower than the main wheels, as soon as the tail wheel touches... the AOA will be reduced and the wing lift isn't enough to cause a bounce....

if you must "Wheel" land.... well... learn to get off the elev the moment the mains touch.. I have known other people who apply a small amount of down elev at that moment.... or trim a little down so they need only let go of the elev and it will keep the tail up....

Re: Bouncy Landings.

A perfect flare and drop on the gear is a great feeling.. with any plane.. Even a PZ T-28.
A lot like a dump without the splashback.

Re: Bouncy Landings.

Mistake #1 is having a 76"ws plane that weighs 20lbs.......the damn things are notoriously heavy, thats why they FALL out of the sky.......and then bounce.
1. Bounce on landing
2. LG wont retract or come out
3. Tip stall and snap on landing or take off
All typicle for a day of flying war birds....If WB pilots would think for just a sec, and realize that just because its a WB it doesnt have to weigh as much as a tank to be "STRONG".....and dont give me the scale flying crap. Fly it scale.....
