    I'm currently building an Estes Interceptor model, and it occurred to me that it would be neat to put in a 24mm to Bt-55 engine mount and use it with D engines. I haven't found any mention of this online, and since I don't have a Rocksim file for the Interceptor to simulate the swapover, I wanted to ask if anyone has tried this?

    Shouldn't be hard to make your own interceptor sim and experiment with the different motors

    I'm sure someone has done this, but I've always been satisfied with my stock Interceptor, I've flown it on Aerotech D10s (but I guess those are being discontinued) and the Quest D16 is now an option.

    I have done it...works nice....just get a 24mm to BT55 motor mount. You WILL need to add nose weight...I can't remember how much I used...if you dont... it will cartwheel. Add nose weight add it will scoot along nicely!

    Oh... I also went with a 3/16 launch lug when I converted it.....just to make sure it leaves the rod straight.

    The 18 to 24 mm upgrade is a great option! Add nose weight. You can still fly w 18 mm engines w an adapter.

    Cool.

    I will try to add some nose weight and see how the string test goes, before gluing in the 24mm/BT55 mount.

    At least it appears to be workable. :)

    I considered going from 18 to 24 on a couple of my heavy rockets, but chose to go with the AT and Quest 18mm D engines. No regrets.
