My last flyer was t' Ranger, shiver me timbers, on 3 x B6-4 with Estes (black tip) igniters. Arrr! I used a Dennis-influenced setup with three igniter leads soldered t' a single wire and t' other three soldered t' a wire ring. Begad! It worked, they all lit and it flew well. Well, blow me down! For t' first time I put one o' me newly acquired altimeters aboard and it beeped out 364 feet.
