Ok. So, I'm a new BAR and was so proud of my motor mount assembly, that I just couldn't wait to get it in the body tube, but even after reminding myself multiple times that I still needed to glue the engine block in I forgot. Oh well, I've searched the forums, and I have a couple different ways that I think I could go, but am interested in feedback.
Rocket : Apogee Diamondback
Mods : Changed the 18mm motor-mount tube, to a 24mm motor-mount tube and adjusted with the appropriate 24-29mm rings from Apogee.
I'm actually also planning on building a second Diamondback with more mods, primarily just to build skills and challenge myself. 3" paper boat-tail, design the back fins to sit on the boat-tail, baffle, and 24mm MMT. Call it DBack squared or something. Anyway.
Options
1. Cut the body tube 1.5" above the forward end of the motor mount assembly, push down and glue the engine block, glue in a 3" coupler (or baffle) and move on.
2. Clip the engine hook at the back end, then push the other end out of the tube. Push a motor block from the back side, then try to put in a screw on retainer (I've read about some using the screw caps from water bottles), but I'm not sure off hand if I have enough room between the 24mm inner tube, and the 29mm body tube; probably not.
3. I did a search on the forums and came up with someone who mentioned just friction fitting the motor. Well, wouldn't I still need a block somewhere along the line? I could still clip the engine hook and insert the block as above, but instead of a retainer piece, friction fit the motor?
I only did the 24mm tube to have options on flying it. I have 24mm to 18mm adapters to still fly it on smaller stuff, but just thought it'd be a neat to do.
Any comments are greatly appreciated.

This is my first post, but I have enjoyed reading through the trove of knowledge afforded by the forum. I'm hoping to do a build thread of the Diamondback eventually, but I build and finish slow, so maybe after I'm close to the end, I'll start putting stuff up. You guys are great with the pictures and explanations, I hope I can measure up.
