I started on a used Hobbico SuperStar 40/OS .40LA bought from a club member,who used it to test TX/RX for his other planes.I just moved on to a 4*40/OS .46AX.I use the Super* to "warm up" with before running the 4*.The guy said last week..."ya know,that trainer I sold you was such a good little plane,engine and all.I wish I hadn't sold it".
