You can still find OS .35FP's, .40 FP's, and .40 LA's new in the box on ebay. These are all perfect for the Kadet Mk II. I picked up my last .35 FP and .40 LA engines for $29.00 and $35.00, both new in the box and never mounted. The .35 FP is for a Sig Kadet Mk I (predecessor to the Mk II).

Other engines that will work are the [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXKF95&P=SM]Thunder Tiger Pro .36 Ball Bearing ABN w/Muffler [/link], [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXGGV7&P=SM]OS .46 LA [/link] (which is on the high-end of power for this plane), [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXFV68&P=SM]Super Tiger G-34[/link], and [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXFV69&P=SM]Super Tiger GS-40[/link] (again on the high end of the power range).

Before you jump on an engine, do some research on them to see what will be best for your specific application.
