After 42 years of launches, here's my first three engine cluster!
The Semroc DEFENDER was fast off the pad with a trio of B6-6 engines. Two were newer Estes B6-6s and the third was a 35 year old Centuri B6-6. All performed up to specs using Quest Q2G2 igniters.
I would guess the altitude was 1,000 feet, the delays were longer than the recommended B6-4s.
Check out the charring between the engines after flight.
