RE: Good second plane for 3D
As far as the radio goes, yes a computer radio for 3-D is almost a must. The 9-C is a good one, so is the JR 8103.
The planes you want should be ok. I am not a 3-d fan. But another source of good 3-d planes is Morris Hobbies. Thier profile series of planes are well thought of. You may want to look at them.
