Whatever 3D plane you decide on make sure it is NOT over 5 lbs assembled with everything. This is the weight I've found that you cannot go above with this engine. At 5 lbs You can hover at about 1/2 to 3/4 throttle depending on the wind conditions (more wind needs more power). So keep it under 5 lbs. And don't listen to what they advertise as weight, they are always over what they advertise with few exceptions. Go on these RCU forums and ask actual owners the real weight before you buy the kit. If you are over 5 lbs, you will not 3D very well with this engine. Keep in mind that you will need at least a half pound of fuel so that will make it 5 1/2 to 5 3/4 pounds wet. Also the APC 11.5x4, 12x4 or 12.25x3.75 are all good props.

That Katana 40 profile by Accel hobbies seems to be very light. Most are between 4.25 to 4.5 pounds. That looks like a great 3D ARF foe the 46FX. Good price too.
