I've been thinking about trying to stuff one in a H9 Showtime. I have the 73" CMP giles/26SS, and it's too heavy for 3d with the 26 - flies imac nicely though.

The 40cc is only about 7-10 oz more, but significantly stronger - for 3D I'd recommend moving up. Cost is what, $40 more?

Right now Brillelli is offering a package deal with an Extreme Flight 74" yak, the 40Gt , Jersey Modeler fuel tank setup, and some other goodies for less than $800.
