I find alot of these comments interesting, I learned to fly with the Eaglet as well in '82. Dad got me the HB .15/Eaglet combo(plain bearing engine). It seemed to have plenty of power. I never did change out the motor, just upgraded to a sweetstik. I'm currently completing an eaglet for my 11 yr old and have a NIB HB .15 for it. I do have a couple of ,25 motors if necessary though
