gp extra 300s
Bigfish,
I have the GP Extra 300S ARF and installed an OS .46 FX in mine too. It is a great flying plane, you will love it. If you have RealFlght G2, it flies very much like the simulator model (I think add-on pack 1)
The manual and assembly instructions are great. The only things I remember having problems with were:
1. Installing the tail landing gear wire per the instructions interfered with the lowest pre-cut hinge slot on the rudder.
2. The manual did not tell you to install the wing bolt-on reinforcement plate.
Other than that it was straight forward.
Best of luck.
Carl
