I love my scratch build Estes/Apogee Mega Der Red Maxx. It was designed by Estes for 29 mm motors and I designed it to fly 38mm motors. I also lengthened it adding a Loc stiffy and regular coupler, longer body tube and extra parts in the motor mount area. I made the mistake of using wood glue originally like the instructions called for. This rocket weighs around 4 lbs without a motor. It can’t seem to take the landings without breaking the fin fillets or worse. Per someone’s suggestion, I added epoxy fin fillets after the first break and it worked great for the next flight. Now the other day at LDRS it popped a fin part way out and dented the outside body tube in upon impact. I was able to get most of the dent out, but my question is, is there is a way to fix this baby properly and keep flying or is it a lesson learned on my first HPR and time to build a stronger one and move on? Can this one by fiberglassed or long boat tail added or something to keep the fins from popping loose? I know rockets with fins that protrude below the bottom tend to have this problem if not epoxied correctly, but I love this rocket as it is big and the large fins give it a slow relistic flight and roar. Hate to retire it. But it is heavy for being an Estes build and perhaps I have built it it too heavy and the weight is more than it can handle.
