Oh, and my crosswind landings today were horrible! I haven't gotten back in the groove enough after an enforced break from flying to be able to focus on the finer points of keeping it over my narrow runway.

No doubt you saw my other post about donating a runway to my flying pals ... 25m long by 1.4m wide ... Now that will take some practice to land on !! Take-offs - that's fine ... but boy is that 1.4m narrow when on finals !

Mine isn't that narrow, but it does seem wide when there's no crosswind.

Also an issue is that 75% of the runway is 'below-grade' a bit, so if you are aimed at the sides at all you need to decide to put it down hard or power-up and climb a bit just to get above-grade.

sorry for the delay in answering. I've been out few days.
Unfortunately no instructor and limited time to spend at the field where there are mainly heli flyers.
Just started this late August with the planes.
I'm flying with a trainer, Jamara Cub J3, 1 meter wingspan, 3 cells lipo. I can take off, fly all the battery with some looping, large and small turn, and few things more. She has flaperons, rudder, elevator and throttle. Really easy to control and fly. No issue in landing even, a part the bouncing.
Few difficulties more with my other bird, a scratchbuilt Ugly Stick, that after lot of crashes and repairs which let me learn how to fly, is now much less self stable, but even much more fun to control. She's a 90cm wingspan on a 2S, 1400Kv motor and a 10X3,8 prop.

Still, i'm learning really a lot reading here... Thanks

Just land it with a bit more attitude (spelled "slower") Don't make it more complicated than it is. (The ground is arriving before the airplane is ready for it)

Flaperons. Everyone's gotta have them. Are you using those when landing? I have 3 planes with flaps, let alone flaperons, and with 2 of them I won't even use them if there's even a little wind. The planes will float too much and bounce at landing. The wing loading on most of our models is so light already. The 3rd model is the 8 and a half pound E-flite F -4 Phantom. It needs them.

Most of our planes, and most likely your Cub, don't need flaps or especially flaperons. They can cause more trouble than they're worth.

I've found the best way to eliminate landing bounce is to release up elevator either at the point of touchdown or just before it.

I did my first landings with wheels today!
OK that sounds odd. I have done 4 landings with a Dart XS (no u/c)
then today I maidened my Lazy Bee, got 4 landings in (controlled) The first two had bounce, the second two were perfect. Im not sure what I did except taking it slow and flying itinto the ground.
I did do a lot of approaches at 6 feet and 3 feet, some were non intentional (too high or too fast on approach).

However I did it! Thanks for the advice on this thread!

1. After I realized I was having many crashes due to stalling during the landing, I did some heavy studying of what was happening. I was mainly crashing when I was landing at an angle to the left/right of the runway due to a cross wind. Since normal depth perception is only about 17 feet, and I always landed further than 17 feet away, I suddenly realized that when I landed at an angle I did not know where the plane was in height, relative to the runway, since I did not know how far away it was. In addition, when I land at an angle, I completely lose my sense of "rate of decent" (I don't know how fast/slow I am approaching the ground). Furthermore, with the plane coming in at an angle, I completely lose my sense of ground speed of the plane. I addition, coming in at angle completely destroys my sense of "angle of flare" because of the geometry of what I am seeing. I searched for a solution and this is what I do now: I only land right-to-left or left-to-right. If the crosswind is terrible I will point the nose a little into the wind. On every landing, I do my best to touch down directly in front of me as I am facing directly across the runway (at a right angle to the runway length). By landing in front of me, I have a better and constant view of the plane attitude, ground speed, rate of decent, and flare angle. For those that wish to point out that the plane cares nothing about ground speed, only air speed, I point out that we fly our planes without the instrumentation to know air speed, and instead substitute other input to arrive at a safe landing.
