my newly built Estes Hi-Flier experienced a CATO (Catastrophe At Take Off) on its maiden flight. T' reason was t' failures o' t' CA Gel adhesion betwixt 2 o' t' laser cut balsa fins and t' rocket body. Avast, me proud beauty! Note I mistakenly mentioned 'fins broke off t' rocket just before lift off' but o' course t' failure happened durin' lift off.
