I think this is blown out of proportions and one really should compare the advantage to the chanse of the mod turning out good or absolutly crapp, as i said i found the lighening of the regular blades to have a minimal advange, the big advantage will be if they could be made really light and really strong with weight added in just the right spots. EP symetrical blades are out now. BUT my whole point about this is that newbies shouldnt get ideas like these into their head when starting out with these helis, issues like these are waaaaay down the line from where you are starting out with no epxerience. Im no big "fly stock" fan per say but I know what people starting out with these machines will think, rather than mastering the challenging flying of these bird they start to think it must be something wrong with this thing because i can make it fly. Then they start acting out in desperation and put their money in the pockets of say hellihobby who is laughing themself bendt in half of all the "crapp" they are able to stuff into the hands of newbies without a clue who thinks "this is gonna make it work". I have nothing invested in making people do either this or that but i recognize the situation and can keep my mouth,,,,eeh keyboard when people are being given crappy advice, and i apologize the "moron" remark was not aimed at any person in specific. Fly on!!
