never too young to try new things!! imagine if einstien's dad told him to for get science!! or bell's dad told him to forget electronics!!!
i do understand that dad prolly doesn't want to finance this but don't they have metal shop where you go to school? would make a great project and i bet it would get an "a" too!!

no metal shop? how about at the local community college? they usually have metal classes and you could take a course over the summer and build it there!

just a thought...

EXACTLY! Think of all the property damage that would cause! all the death and destruction that could be accomplished just by using a metal prop! i could go on a rampage! i could have so much fun!...
just kidding. a metal adjustable hub would be just fine. i can get blade halfs any time i want, but i need a hub to put them on. he never suggested using a metal prop. he suggested metal shop because adjustable prop hubs are hard to come by and extremely expensive.
