I had a sudden urge to build a rocket (that happens to me on occasion) and I wanted it to look like a jet. I especially like designs by Shrox and borrowed some inspiration from him while perusing this thread. The result was this: For a starting point, I used the BT-80 body tube with 29mm motor mount that I originally assembled for the Plasma Dart II XL (before changing my mind and building another with a 38mm mount). I also added four 24mm motor mounts for more air starting fun. With up to 5 motors in the rear, I'll need to be very mindful of weight and balance, so I'm going to try and pay attention to the real weights of the parts as I build this.
