I use the stockblades made for the head. I have ask Vic from V-blades to look in to making me some new ones out of carbon .. these blades are made with a little turn on the end of them.
like a big v shape.....
As for whats first .. If you are flying a sport and have it down to were it is smooth than go for the head setup .. ...YOu can allway get a body some were ... Oh ,, the way I look at it is ,, If you want something to look at right now than get the body first ,,
But by getting the head first .If something does happen than you dont want have to replace a nice body .. Be sides most of us keep our bodys clean .. And when you are setting up a 4 blade head it is going to take some time to make sure its right .. ..... than get your body and paint it .. because the first time you have it all together .............................Well all you will do is look at it .. you want want to fly it,haha..........
