I bought the combo with the 46 from brillelli after reading the review you wrote, (nice review) but i never received the engine. I just bought an RCGF 45cc, i only fly sport but i like to try to 3D once in a while, this will be my first gasser. I want to switch from nitro to gas cause the closest hobby shop from here is 3 hrs away and it's a pain to get nitro, unfortunetly i won't be flying this plane this year as hunting season is starting next week and by the time the season is over it is too cold with lots of snow.
