basic modeling tools like screwdrivers, a small saw, sanding tools, lots of CA glue, X-Acto knife with lots of blades, a flat building surface, metal pins, a dremmel is very helpfull but not manditory.......ext. you can do a search for the 4 star on the web and some sites have a copy of the instruction manual you can download. the manual has a list of everything you will need to complete the plane.
the four star models are laser cut and goes together very nice with little need for sanding or cutting to make peices fit. if you follow the instructions you will have a good plane. i have not found any weakness yet and i have flown mine at least 50 times. a lot of people (including myself) add different styles to thier 4 stars. it is a great base kit to turn into whatever you want.
