Personally wouldn’t say a rebel hot or a viper jet is a trainer, I would say they are a second jet. Something like a xcalibur which you can get in every category in size and fly great are a perfect trainer. Bigger models fly easier in my opinion with lighter wing loading and ease to see it in the air. I’m not sure if you’re looking first jet or not but xcalibur is perfect. If it’s second jet the rebel would be great. But there is a price difference if you’re learning to fly jets xcalibur won’t cost as much in parts as a rebel. But this is just my opinion
