The Sig is a fun fly plane with large control surfaces (flight will be very close to your Fazer). The GP Tracer is a "pattern" type plane. Even though it is possible to fly with the Sig you will most likely have better luck with the Tracer.

Other "pattern" choices:
Super Kraft (aka Kangke) has a nice model called the F3A
The TaiJi is a good choice and is avaialble in different sizes.
Zimpro has several pattern offerings (aka Tennessee Model Prouducts)
Hanger 9 Aresti
Tower has a Venus 40 // Kaos 40 // etc
Global has the Quick Fly III

All of the above and dozens more are available and all good choices. What will make the difference is how much practice you do.
