Ah, for a second plane I would recommend something more docile than the Red Arrow. A 4-channel aileron trainer would be good. This is the stage I'm at right now... I'm still sort of a newb at all this.
Most people recommend Mini Magister, E-starter, Gemini, or Tiger Moth 400. Of those, I guess the E-starter and the Tiger Moth are the least recommended...even though they're all good trainers. I picked the Tiger Moth 400 because of its looks... although S.C.C. almost convinced me on the Gemini.
I'm still building that Tiger Moth 400... right now I'm learning lots about chargers, batteries, radios, etc. The folks here have been insanely helpful... so kind with my battery of questions. Would never expect this much help from strangers on the street for sure. But yeah, I'm hooked already. Not sure what I'll do after the Tiger Moth... maybe a larger balsa plane... or a Warbird like a Spitfire or Focke Wulfe. I also like the S.E. 5a. So many to choose, hahaha. Sort of like you've got your eye on that Red Arrow.
Good luck mate.
