I'd use an E engine in a heartbeat but when I look at the launches (see videos themselves if you like) I'd be concerned it'd still be unstable. I did my best on the Cp-Cg thing

Think I might have to simply retire it on the shelf...if this D12-0 scheme does not work

Thanks

The E15 will stomp the heck out of it compared to a D12. You can add all the nose weight you need to get the CG where it needs to be and it will still jump off the pad. You will need a decent size field compared to the D12, though. Unless it means something special to you, fly it on those composites when you have a big enough field. Build another one completely stock to fly on D12-3's on small fields. It makes a great demo, pretty much coasting to a stop and ejecting the chutes at apogee when flown in calm conditions. If you want to get a little creative, build it with a removable mount and play around with 18mm clusters. It can be flown on 4 B6-2's, 3 C6-3's, or 4 C6-5's with great results. Each cluster listed is slightly more powerful than the previous, giving you the ability to fine tune your model for the field size.
