I would not recommend the ARF FliteStreak as it is too fragile for a first CL airplane. Brodak has a Lightning Streak Trainer which is a 15 -19 size airplane and the sort of trainer I would recommend. Solid wing, external controls, strong motor mount. Brodak has a large number of CL airplanes, kits, ARF's and ARC's. The mostly 049 statement is not correct. RSM has a number of kits. Sig also has a few. The Sig Skyray would be a good second airplane.
Take a look at this.
