I built one and it flys great. Altidude here is about 4800 feet and 80% of the electrics will not fly here. The real lite ones are fine such as the Tiger Moth, Belliot but the wattage line is a bunch of nice foam that are great for my 3 year old grandson to play with( ie sporty) I use a Jr Micro rec and servos and Jettie speed control. I know that many of the reviews on some electrics appear good but not at this alitude. Constructon is easy and quick use CA and keep it lite and you will have a nice bird. Good Luck
