I am continuing with my tailwheel training.
I found out that taxiing in citabria is not so difficult at the end, but just requires very precise pedals manipulation.
There are two different landing methods: the first is when you keep nose-high attitude and let the tail wheel to touch down, and then apply even more pull force to slow down until the main wheels become on the ground too. The second is when you keep the airplane’s nose relatively low, and very gently and precisely let the main wheels to contact the ground while still keeping the tail wheel in the air.
The second way is much more challenging, and requires very low vertical speed at the touch down moment. Moreover, it is a little counterintuitive: you have to push the stick then the wheels are on the ground, the reflexes force to do the opposite.
Flying and landing a tailwheel airplane is really interesting. It improves visual flying skills (especially directional control and landings), so if you are a pilot (or thinking to become a pilot), I strongly advice to have this experience.
