RE: improving rudder skills
The 40 sized Epsilon is available here but I have had my heart set on the 90 for a while. I have all coreless servos and premium accessories and I am going to take my time and do a deluxe monokote job. I cant wait.
The only CA kit I have built is the FUNKY. It was kind of a tough first kit but it turned out fine. I have helped some friends build a few WB40´s and the quality is great. I expect the same with the Epsilon.
