There is more than one way to skin a cat-If you want a 12 pound engine there are many out there-Just as good as Jet Cat-Look at the Wren 54 or the Artes Bee or the TJT Deamon,PST 600, SimJet, FTE T-500 or SWB Mamba. A very good rumor has it that Wren will have a 17# engine out very soon that is about the same size as the 54. Peer pressure doesnt stop at high school. Scott
