ya I am really takeing my time with this rocket being it is my first one in a long time i am fealy injoying it to now i am molding the filliets, with micro- fill seems to be going good since it is the first time i have ever used it, i am a little worreyed about the glue i used { SIG } super weld liquid resin, it says it is model air plan glue, now dont get me wrong it make good fillets, but it did seem to take a long time to dry. also now that i started molding in the fins the fins do have movement from side to side not alot but thay will move, i think this will be fine as far as strength, and when it touches down i feel the fins are not so ridget that the fins will give alittle, but i feel that,,that little give will crack the microw fill, if you understand what i mean.. i am not shure if i should have when with epoxy. as far as color i do want to go with some thing bright and can be seen in the air and on the ground, red makes sense, all red lights are red far a reason, or orange,
