NO. Definitely not. It's my guess for a free flight scale model with that enginel, built light. You really need to check with a group that flies scale models with that kind of engine. And my guess is that most free flight scale fliers are using either rubber power or electric. As you know, glow or diesel power is messy, and for free flight there are better alternatives . Try a Google search for .049 scale free flight models. Might give you a better idea of power to size relation.
