I'm with Rcpilet here. I'm pretty sure that a Funtana 40 is not going to 3d very well-if at all-with a 46. A 46 with a pipe or tower muffler is right at the bottom of the range for a 4 1/2lb fun fly. Most of us profilers use a Saito 72-82, or a 50 class 2 stroke with an improved exhaust system for a 4-5 lb plane. For a 5-6 lb plane we use a Saito 91-100. For a 6-7 lb plane a YS 110 is about right. Watch the videos posted here of the planes being considered that are really 3D'ing. You will probably find some impressive videos by Kyle using a YS 120 on his 90 size Funtana & Show time.

Profilers that regularly write their names in the dirt with their rudders would laugh at the idea that a Funtana with a 46 can do 3D. The Funtana 40 3D videos posted here at RCU that I have seen have a Saito 91.
