How many of you guys/girls use foam inside the fin can after internal fillets?If you do what kind of foam do you use?Is it worth doing?Thanks Alex
What kind of foam was it? I know PML sells special expanding foam. I've never used it though.I used foam in my L2 bird because I expect to use up to L motors and Mach 1.4+. Even with that, I'm not sure it really adds anything to the rocket except weight. I just used the expanding foam in a can from Home Depot.
