Hmm... any nose down angle should make things worse I would think. The motor is already above the CG, that should give it a nose down moment. Angling the motor tube nose down should increase boost problems.

But you did not see this on yours? Strange.

The Space plane solved the problem of residual lift during boost with spin tabs, that is not an option on this rocket without an extensive redesign.

One thing I find curious is that people have only had stability problems in the pitch axis, not the yaw axis. It looks like it does not have enough fin to correct yaw instability, the dihedral will help but it does not look like enough to me.

Anyway, I ready to attach my motor tube assembly so I need to decide soon.

Thanks
