Hi Charles,
If there are no Nos 30 events then you are out of luck with the Imitation - except it is still a GREAT contemporary design.
The fuse on the Imitation is no wider than the fuse on the Classic Era Excalibur. Mustunt 1's with crutch style fuselages are also typically are allowed in Classic.
Pity we do not have a nationally recognized standard definition of a profile stunt model....
The only place where fuselage width is mentioned is in the profile scale rules. The definition of a profile stunt model is simple, it should have a side mounted engine on a slab style fuselage. I don't care if it's a foot thick!. Look at ALL the profile kits that were produced during the 50's, 60's 70's and so on. They all fit this description, side mounted engine and slab style fuselage. The problem lies with people that don't want to accept this and inject their own view of what it should be, and then the fuselage width thing comes back in. The Imitation with an R/C type engine mount does not fit that description.
There has never been an official AMA rule on profile stunt, and it has always been just a fun event. The P-40 event ( or Profile 40 event) originated along these lines and just inserted the .40 size engine limits in order to sort of level the playing field and banned tuned pipes., again, trying to make this a fun and/or an entry level event. SIG was the originator of the P-40 event along these lines. Here in St. Louis, we fly their rules and added a 10 point (I think) penalty for electric models, because they have a distinct advantage in that there is no way to mount an electric motor "side ways." You can get that back by having an electric model with no flaps and get the 10 point bonus. Lots of electric P-Force models out there.
This has all been argued many times before by people that have a model that doesn't fit the description, but want to fly the event and try to force their way into it. I think it really is quite simple by saying a profile model should resemble a typical profile stunt model kit.
Type at you later,
