I did not know the giant and 120 size came in ARF--How much and where do you get the Giant Stinger ARF--(ps--they are great flying planes) If it is a Stinger you really want, I would either sell the 44 or save up and get a G62, The 62 is the perfect engine for the Giant Stinger--although they are correct-the 44 will fly the big'en OK.
