RE: Help in choosing a trainer?
This sport can be tough on money. I think I spend at least $200 bucks a month. It cost about $800 just to get started in glow. Try and find a good used trainer if you can. Most clubs have a classified of some sort. You can buy a flight sim used here or on ebay. I would highly reccomend one of those (flight sime) - just to get the thumbs working. I bought a used Tiger for my second plane $50 complete. Its still my favorite.
I've built a few planes from kits and they ended up costing more than an ARF. I still like building them from kits best.
The Nextstars look great and it does seem like a good deal, however, it is a first year model and it takes time for all the bugs to get worked out. I think I would try something more tested and true like maybe a Kadet.
Best of luck. You won't regret the switch to glow.
