I built an astro blaster about 23 years ago and it crashed upon take off. Due to lack of interest I never got around to repairing it. I just have pictures of it now. I got away from the hobby for a long time and was preoccupied with my career. Some time after retiring I got interested again and tried several drones. I didn't have good luck contolling them either. I toyed with theidea of building a trainer from plans rathe than a kit and had it all planned out but several hobby store owners talked me out of it. Theysaid that Iwould justcrash and be disppointed. One of them said thatnobodybuilds from kits anymore. I don't know if thattrrue but my ambition for it has waned. I wouldrathergeta plane that it rtf that is like the slo stcikor theglideriftheyare possible to fly without crashing them constantly, especially in small areas. I've seeen the slo stick fly indoors on you tube, so maybe thatanswers part of thatquestion. Itlooked like the guy was pretty experienced though. My doctortoldme totake a step back from the sport since I have had severalinjuries when retreiving planes from crash sites. Maybe if I get back into it someday Iwillconsider one of these planes thatyoufolkshave mentioned.
