Phoenix scanner, WM Super stunts, WM Mach raider, Tower Kaos, etc are all the same airplane. Same box type construction, similar dimensions, same semi-symmetric wing. Phoenix has another in this type called Dolphin 40. Its the same engine size but has a 60" span and hence is more stable. However, its less reactive and very lightly (cheaply) built. The advantage with the Scanner is the metal pinned hinge from factory (atleast of or ours have those) whereas I recently saw a dolphin with the nylon hinge sticking out of the aileron even after being flown OK just a few flights.

Phoenix is ofcourse the cheapest of the lot
