i dont mean to rip on os but the 61 fx is a 3d paper weight it has a lower power to weigh than the 46 fx dos i say it will hover it but thats it 4 stroke is what makes the fly the best i just got started on mine with satio 100 so if you dont mind spending money for a good cause the satio 100 is the engine for i think and the carbon rods for the tail yes they need it but it wont hurt to put the normal flying wires on it some stabs have snaped off with the rods on them
