Your not using that much oil,your to buy the 10 percent nitro,10 percent oil content glow fuel.When mixed with the gas you probably only have about 8% oil content maybe.And the ryobi will never have the power of a Q50.Look up ryobi 31 in the search bar under this forum and youll see what it flies.The ryobi may fly it but i dont think very good,but i could be wrong depending on weight.
