Josh,

It's quite amazing that the fuse length of the T-825 is only ~4" longer than the T-720 which has a glass fuse of ~51" and a total length of ~56" (spinner and rudder included).

Also, you mention plans! If you have plans for the T-825 (Hipo), then cutting cores for it might be quite a bit easier - only the tip and root airfoils of the core would be needed from your left (unwarped) core if they are not also drawn on the plan.

David.
