Loswav,
The flatbottom blades seem to give the most lift for just starting out. If you go to li-po and ereobatic ehancement kit you will get longer flight times. You might want to practice hovering first and then using a car mat or like object to practice taking off and landing on a specific simulated heli-pad. I can hover tail-in fairley well but now I have to work on nose in hovering. and then flying in a circle. I have a set of CF blades but dont fly with them in tight confined areas yet. I have used them outside on a calm day or in my large shop with 12 foot ceilings and find them to be much more sensitive and responsive. I have installed the helihobby alum frame and tailrotor cnc frame parts for 2 tailrotor motors on one of my blades. the more flight time that I put in practicing the better I can hover and do precise helipad landings. It would really be nice to have a very large Gym or factory building to fly-in. Keep plenty of parts on hand if you plan on high flights in windy weather. One time I was flying and the wind got under the blade and before I knew it i was at the top of a tree with shading that made me lose orientation and resulted in a crash. I cut the throttle fast and it saved the blades but not the skid and main frame socket where the skid rods join the frame. Lots of luck,
