I was 12 years old in 1966..when I launched my 'Astron Alpha' and then 'Big Bertha' with 'A8-3 and B6-4' engines.. It was astounding! Now...decades later..I'm getting back into the hobby... Never knew these incredible advances!
There are several kits that could actually be used for both Level 1 and 2 Certification. One that comes to mind is the LOC IV by LOC Precision. Another good choice is the Apogee Zephyr.
