On request from many PIKE Perfection pilots we offer now 5,3° dihedral joiner in all versions for the Pike Perfection.
We recommend it mainly for light f3j and f5j versions. Flying with this joiner will give better performance in circling. Unfortunately an adverse effect with bigger dihedral is worse for penetration. A good pilot will manage circling also with small dihedral (3 degree main dihedral joiner) and will then not loose any penetration.
