RE: Best Second Plane / First Build KIT
rik756,
Look around for models that are advertised as intermediate or aerobatic trainers.
The can be low wing shoulder wing even high wing. Pick one you like and have fun
As you can tell evetyone here has an opinion but when you boil it down the only opinion that matters is your own.. If you are as good with the trainer aas you say then you should be able to handle any in the category I mention.
