Moving up to E power and launched the 3rd version of my E-12-6 min Diameter mini Rocket today. Some said it would never fly but it couldn't have been straighter, even with 16 mph winds. Version 4 will be a little taller with smaller fins or a one piece plastic fin unit. My field isn't huge and I'll be launching C engines mostly but the sight and sound of the E-12 is something I need to experience once in a while.
