ask usual questions time say have build planes get discouraged sport everybody people patient enough build model avoid telling people about ARF models because think take feeling sport Im sure modeler remembers first time saw plane worked days get airborne its feeling pride joy ARF models take feeling away So lets suppose person buys ARF trainer learns fly Now wants better plane performs beyond trainer level now pilot has no building skills almost no high performance ARFs pilot stuck what pilot says never want enter competitions need high performance ships Maybe year two attitude will change does want compete pilot wont have building skills build ship needed competitions person says dont have time build plane maybe should think twice about entering hobby half thrill have plane built own hands fly its feeling cant really explain Thanks time A/i Khani Torrance Ca/ifornia ro/e ARF has debated since such mode/s first appeared Its great feel pride craftsmanship simply want get out fly ARF

neighbor fellow modeler Dick Lee said try some stuff Steve Aidridge Boise Idaho enjoyed Graham Hicks article about dangerous chemicals used hobby Acetone chemical article Mr Hicks mentioned very hazardous have flying ARE models last four years have plastic fuselages method repair soak plastic shavings acetone makes putty-like substance use patch cracks holes Instead pure acetone use nailpolish remover has enough acetone repairs though may take bit longer diluted has conditioners make less hazardous Mark Atkins Oklahoma City Oklahoma have gleaned lot useful modeling information

ask usual questions time say have build planes get discouraged sport everybody people patient enough build model avoid telling people about ARF models because think take feeling sport Im sure modeler remembers first time saw plane worked days get airborne its feeling pride joy ARF models take feeling away So lets suppose person buys ARF trainer learns fly Now wants better plane performs beyond trainer level now pilot has no building skills almost no high performance ARFs pilot stuck what pilot says never want enter competitions need high performance ships Maybe year two attitude will change does want compete pilot wont have building skills build ship needed competitions person says dont have time build plane maybe should think twice about entering hobby half thrill have plane built own hands fly its feeling cant really explain Thanks time A/i Khani Torrance Ca/ifornia ro/e ARF has debated since such mode/s first appeared Its great feel pride craftsmanship simply want get out fly ARF

neighbor fellow modeler Dick Lee said try some stuff Steve Aidridge Boise Idaho enjoyed Graham Hicks article about dangerous chemicals used hobby Acetone chemical article Mr Hicks mentioned very hazardous have flying ARE models last four years have plastic fuselages method repair soak plastic shavings acetone makes putty-like substance use patch cracks holes Instead pure acetone use nailpolish remover has enough acetone repairs though may take bit longer diluted has conditioners make less hazardous Mark Atkins Oklahoma City Oklahoma have gleaned lot useful modeling information
