The Northstar has been around for 20 some years now and a lot of fellow modelers have modified the Northstar both aerodynamically and aestheticly.They have been made big and small,ducted fan and turbine.I'm building a 150% Northstar,while I'm not changing the basic aerodynamics I am changing the apearance.If you take a step back and look at the basic airframe,this is a wonderful platform to create any type of plane/jet/electric/whatever you want.Boy's let's see your creations.
