I just bought one of these in the PW color scheme. Have not started assembly yet but a few thoughts - I am going to use a Moki 1.80. Your YS will fly it but I don't think you'll be happy with the power. This plane will weigh about 14+ lbs. I will replace the tailwheel with a Haigh style for a more scale look. The kit looks very well built but I really haven't had it out of the box except to check for damage - and to polish the landing gear.
