D and E Model Rocket Engine Mount Kit

I love engine mount kits because they have all of the parts that I need, no searching the bottom of my builder’s box. Be patient, make good glue fillets let the glue dry overnight and your reward will be a light weight and strong engine mount

The kit is fine for standard (Black Powder) BP 24mm D Motors, but with BP 24mm E motors on up, you must use 2 engine blocks and epoxy only, no white wood glue. Build up fillets, with epoxy, when installing in rocket. The engine clip is the weak point and I would use a threaded 24mm Estes engine retainer.

I bought myself 3 of these for a intended 3 stage mid-powered rocket build. I ended up going with two, but it was well worth it. I sat down and read the instructions, they were very clear. I was also happy to find that the kit came with centering rings for a standard BT-55 (or 50, forgot for the time being) and a BT-80 body tube. I used a BT-60. The rings were easy to cut out with a standard hobby knife. The kit also came with a standard Estes engine hook for E size motors, and a D hook, if you only want to fly your rocket with a D motor. This is really not needed, for the kit comes with a D motor spacer. It is orange, and fits into the tube and makes your D motor the size of an E motor. Its a really nice feature for the kit. The whole kit was really easy to put together, and fit nicely into my tubes. My only concern is that you really must glue your hook down. I found that on my first stage, which I threw and E12-0 in, that the hook moved up past the ring. It was secure enough to keep the motor in place, but ripped off the top of the motor mount tube. Overall, these motor mounts are really secure if you follow the nice instructions. They can take the beating of the higher end of Estes BP motors, and look nice in your rocket.
