I'd say go for the Nexstar. 40ish sized glow. I started on electrics. They are either really underpowered (stock motor) or nicely powered (brushless motor) but your gonna pay for it. I have a sailplane with an 05 sized brushless motor. This thing moves out!!!!
Plus, it glides pretty nice. Also, if your thinking of electric, the best trainer pound for pound and the most durable is a T-52 from JK Aerotech. The kit is $35. I put on a $20 car motor (mag mayhem) and a $20 gearbox. Fantastic performance without the brushless cost. I have roughly 20 electric planes. All but two of them use the suggested motor. All the rest are aftermarket motors and brushless. I also solder my own battery packs which really drops the cost of batteries. I fly both, electric and glow. I have lots of fun with each.
