That simplifies a lot.
Note that the ''side'' roundels have changed in 2017-2018 period. See this image as exemple
As for the squadrons, you must have the 410 as this is the Tactical Fighter Operational Training Squadron.
Would be a good thing to have the 401 or 409 (Cold Lake) as the West component, but i would surely put the 425 or 433 (Bagotville) for the East component. And i would not go with more than 24 birds (2 sqn of 12 unit) if it's to fill a gap (we don't have that much money) :)
For the Sqn decals, a lot have already been done on the CF-18 i made the decals for on the ODS30th anniversary project. Might have to take a look :)
As for the name, as there is already the CT-155 Hawk in RCAF inventory and going with the RCAF plane number designations, i would doubt they would name the F-15 CF-155. So I would go with CF-115 instead. All serials number will have 6 numbers beginning by 115 (115001, 115002, and so on).
You can send me what you will have done and test it with pleasure and give you my comments :)
