I think I'll go with the Irvine 39 on mine... I like the idea of color coordination...
Looks like my 'heavy duty' radio gear (JR 811 digital servos and 1100mah batt) will be going into a H9 Funtana (saw it at the LHS and it jumped into my arms

) so I'm thinking of making the airpack lighter too by using minis...
The Irvine is a couple of ounces lighter than a 46FX and almost as powerful, hopefully I can make it balance...
