I'm building an old G76-10 green load for the 29/40-120 casing (with a copperhead ignitor ) and the instructions have no mention regarding adjusting the delay. The old delay tool I have is for 38mm loads and the delay grain for the 29mm load doesn't fit. Balsa Machining lists an RDK 7 second delay for this motor but I seem to remember that drilling the delay grain 1/32" for each second will give you the correct delay.
Has anyone done this? It's been so long since I did a motor delay I can't remember if it would work.
I also considered adding a chute release to this Nike Smoke, but have had mixed results.
Any advise would be appreciated.
