Some people say that there's a strength difference between the 5min and the 30min stuff when they're both fully cured Jon - but I've never seen any believable data and it ins't going to be noticeable on a model plane anyway. The 5min stuff is perfect and I always take some to the field in case it's required. As long as you mix the hardner and resin well, there's going to be no difference between them as far as your model goes.
