I have the phoenix tucano and super decathlon. Love them both. OS 55 Ax in the Super decathlon and Fox 45BB in the tucano. No issues during either ARF build. Only problem I've had with the Decathlon was my fault. I warped the canopy while using a heat gun to smooth out some wrinkles nn the fuse. I found out the Phoenix doesn't stock just the canopy. You have to order the entire fuselage! Which IMHO doesn't make much sense, as you can buy the side windows seperate, but go figure. Anyway, you might want to check the tower parts express section, to see what is available in case you ever need it, for the model you're thinking of getting. I leared a good lesson on the use of heat guns, and it forced be to take up vaccum forming to make my own canopies. Should have the vaccum table ready for testing later today. I do like the phoenix model line. well built I think.
