I was surprised how many steps on the Estes Conquest say to use CA glue. I hate the stuff. I know that some of it is so things set fast. I used the green Testors on many steps and plan to go back with some serious Titebond fillets. Is is just setting or are there strength issues as well? I don't mind gluing and waiting most of the time. On a side note I guess the designer of the QRC explorer loves those intakes so much they had to be used again.
