I maidened my Groovy 50 3A today with help of a more experienced friend and it was a suprisingly nice flier. It was kinda hard to get CG to the right place with light YS63. I inverted the landing gear and moved battery pack to firewall=perfect 135mm.

Tomorrow I am much wiser and make some minor adjustements. Elevator was too juicy anyway with suggested throws and needs to be cut half or 3/4.
