This is a balsa kit having a 26 inch wingspan that you will need to glue together and if flown radio control needs all that put in.The box says you can put a CO2 motor in it but all my husband ever did was use a small motor like .020-.049 engine or small electric motor.Since this is a Hacker kit all the cut out parts are laser cuts and very nice.Usually I ship UPS ground therefor no PO boxes,thanks Peggy.
