Re: Bouncy Landings.

I find that full flap landings are my favorite as long as the wind is not too gusty and I am not fighting a strong crosswind. In those conditions I always do a no flap landing. All I fly are warbirds in the larger sizes and I like to bring them in for a wheel landing and roll them onto the runway. A little fast is better than too slow. If you get slow they will sink too fast and bounce every time. To solve the bounce problem when coming in a little fast I pull the flaps up as soon as the mains touch the ground. This kills a significant portion of the lift and really sticks the plane to the ground. The best advice I ever got was to fly it all the way to the ground. I had the tendency to get it close and let it land its self....that did not work well for me, but once I realized that and started flying it to touchdown my landings improved a 100 percent.

Here is a slow motion sample of the landing technique I use. The flaps are on a slow servo so they do not jump up when I raise them but retract slowly. Notice on the roll out as the flaps come up the tail drops and event though the ground rocks the airplane on roll out the wheels stay stuck and it never gets back in the air. For sure it helps to have a long runway so you can slow down straight ahead once you are on the ground.

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...........


Great answer.....bad analogy haha

Hi ,
I Had The Same Problem With my 1/5th Giant Scale Top Flite P-51 Mustang .
I am using Robart's Retracs And Wheels . the " Oleo's Were Sprung too stiff for my plane .
My Mustang Wheighs in at ( 28:lbs -- All Up , ready to fly ) , I pulled the " Oleo's Struts A part , And cut The Spring A little till it settles from ( About 1/8th Of a Inch ) full strut Extension , Also Applied Some White Lithium light grease To Dampen the Springs .
To test the setup , I Put a Thin O-Ring On The Bottom Part Of The Strut ( The moving part ) , Push the O-Ring Against the Upper Strut Tube .

I Then Dropped the Plane from two (2) Feet from the Ground , On The Main Wheels . now check to see " How Far
That O-Ring Has Moved .
If It Is All The Way Down You CUT TOO Much Of THE SPRING OFF .. ( It does not take much to make a change ) .
Now If you Come in too hard for a landing , You can see the Wheels Moving Up and Down Verses A Big Bounce .
Hope This helps .
Later,

Please don't drop your airplane from 2 feet off the ground.

If anything drop it from 4 feet while filming, then post the footage.

I have the 1,7m wingspan Seagull Zlin. It flyes great but at landing it-s a pain. There aren't many videos with it on youtube, but almost in all it bounces. I don't know if it's because the mains are too mouch in front and it's tail heavy once on the ground or what because my CAP 232 27% for example it doesn't do that. So..after a good search on anything I could find on the subject, inlcluding flying the tail, practice slow flight, trim down elevator for the after contact moment etc..I'm still in the same place. So my question is a more excentric one: what if I mount such a long tail wheel that the fuselage will stay almost orizontal when on the ground, likle a tryke plane, that has a nose wheel? So that the tail can no longer drop after contact an increase the wing angle and the lift, I know it would look odd but will it stay on the ground then at least untill I get to know it's beahaver better? Something like in the photo..

If it can't be slowed down more before touchdown (preferred), then try programming a switch for spoilerons. Kicks the ailerons up and kills lift. Don't do it until right at touchdown.

It is a real balancing act that requires a fluid motion from flying to driving. Some planes will do best on a three point but if the tail touches first due to AOA being greater than the on wheel stance it will pop down on the mains and bounce back up. Most warbirds will like a wheel landing better. I find it is best to just dirty it up with the flaps and fly it to the ground with no defined flare or hold off.. It leads to a faster landing speed but generally will not result in a bounce..
