I'm building a Binder Design Jaguar and am starting to wonder if I should foam the fin can or not.
Build is with 30 min epoxy with milled fibergalss. Fins will have fillets to the motor tube, to the inside of the body tube, and to the outside of the body tube so basically six fillets to each of the three fins.
I will be pushing this rocket with a J570 and it should be breaking mach and over 50g's according to my sims. (wrasp)
So will foaming the fin can really do anything for me in this application..??
If so are there any good foams to use that can be picked up at Lowes or Home Depot.. I really don't want to delay the build anymore waiting on foam by mail order if i don't have to..
Thanks for any advice....
