OK, just had a look at coils, and they pretty much identical, crown2 coils holes slightly bigger, and bottom coil shapes obviously different, but you can pull it out and swap it, so you'll have a coned shaped rafale coil which perfectly fits in crown2 tank.On the fence at the moment with the Crown 2... loaded it up, bedded the coil in ( 0.2) and it was great, even at the manc meet people liked it..BUT after 4 days the coil died.. was producing nothing... Inserted the stock 0.5 which was the other coil that came with it and that seem to last for about 5 days... Didnt really push them wattage wise but very disappointing coils. Wanted this tank to be great as the v1.. Sat on the back burner now back to my RTA vcmt.... I did see somewhere that the Rafael coils will work in it??? anyone tried with success yet?
