Hey everyone! Im a BAR and am now just moving into MPRs. Im currently building an AT Mustang and from what I have read it should be a good intro rocket. My question is if anyone has used JB weld for building instead of epoxy. Ive used it on other hobby projects and it worked great. If not, what is the recommended epoxy for fillets and general on MPRs. I just got my AT rms 29/40-120 case ,so i guess my next question would be what is a good reload for the mustang?
