I have an ASP 52 which is made suposed to be the same as the Magnum engine. If its similiar, the power and reliability is fantastic but it does tank lots of tanks of fuel through it before it settles down and runs smooth. Its also a bit finicky until it settles down. Mine took about 8 tanks compared to an OS that is good to go after 4-5 tanks. For someone just starting out and wanting to start flying the sooner/better the OS or Thunder Tiger may be a better choices. [8D]
