I see that Horizon Hobby anticipates the new 50cc in July. Currently I am running a 45GX2 with great results, but always wanted 5 cc more power. For practical purposes lets say that my 45 has 1.85hp /lb. Factory specs. Does the 50 have the same or greater rating? I see that the engine is 9 oz heavier and it must make 6.2 hp to match the power to weight of the 45. Would it be worth a swap? What will it swing a 22x10 to? My 45 swings a 22x10 to 6900 rpm.
