The 4* is a great second plane. Years ago I built a 4*60 and put a YS .91FZ on the front spinning a APC 15x6. This motor is supercharged and has the power of a 1.20 4-stroke. It will hover, torque roll, flat spin (true flat spin), fly inverted, do blenders and does the best knife edges for the type of plane it is.
If you are a scale flyer, the a 52 or 56 4-strk would work and work fine, but if you like to 3D some, then I recommend a OS 70, Saito 72, 82 and even a YS 63. Tons of power in any of those motors and you will really love the plane more. Having extra power doesn't hurt and plus you don't have to fly at full throttle. My 60 size with a .91FZ is a perfect combo. For me atleast. I still enjoy flying the plane years after building it. I did add a few mods to my 4*60 such as counter balance rudder, pull-pull rudder, dual elevator servos, 1" addition to the control surfaces, bomb drop door in the front plus a few other changes.

OOOHHH YS power on a 4* holy crap...
Feed it high nitor contents and holy crap become OH MY GOD. That had to have been a phenominal mix. Heck I'll screw in my YS110 to my 4*60. The thing hauls my 11lb funtana around nicely, In the 4*60 I'd have a missle with big wings
Haha, I do run 30% in both my .91FZ on my 4*60 and 1.10FZ on my Funtana S90 also. The power that those engines have are unbelievable. You have a YS, so I'm sure you understand exactly what I mean. The 1.10FZ has power that you wouldn't think a 1.10FZ should have. My buddy with a FT90 who has a Saito 150 can't believe the power it has and would actually say is stronger than his 1.50. It is compared to the Saito 150 for power though.
My FT90 only weighs 8.62 lbs (dry) with a YS 1.10FZ. Think about how your 11 lbs FT90 flys and take off a couple of pounds and keep the same power plant using 30% nitro.
Simply amazing in flight. Does everything under the sun.
The 4* with good power is a blast too.
