I built a 4*60 last year and still love flying it. I would highly recommend the plane. I did several mods to mine such as a counter-balance rudder, dual elevator servos, front hatch, 1" extra to the elevator and rudder, plus some other mods. I have a YS .91FZ spinning a APC 15x6 prop. I have my CG set a lot further than recommend, but mine will flat spin, hover and torque roll. These planes do very well with a little extra power on the front. My supercharged YS engine is the perfect balance for this plane IMHO. I have heard positive things about the tiger, but I can only rate the 4*60 which is great. BTW, the plane will float forever especially if you have flaps on. The 1" addition to the rudder and elevator allow me to do all sort of 3D stunts, but this is not a 3D plane but can do them with enough power.

**UPDATE**
I added some photos of my 4*60

If you need more I can get those to you.
