The D2.3 is really good for models at or under 5 oz, maybe 6-7 if launching below the required 45 degree angle for NAR rules.
In that size, you should be able to do an E-6 powered version if you keep it lighter, say 10-12 oz rtf, I've done one that size but put the motor in the tail so thrustline wasn't an issue and you can't tell in the air.

Here is a photo of how it compared in size to a common door.
I still have the drawing. It is a complicated build, I would need to go into the drawing and simplify build techniques.
Model is over built-it could withstand 30lbs of barbells placed on the fuselage with wingtips supported on papercups. This project will be looked at in the future-plan to convert to AeroTech D2.3T reloads.
Current project to complete is Saturn V Lamp.
