RE: Next Plane
Your trainers are tricycle landing gear right?
Are you comfortable landing a tail dragger? if yes, then I'd vote for the Great Planes Escapade or a one of the Uly Stik Variants on the market.
Hanger 9Pulse also flies well but I don't like the price vs quality of construction. Just my POV, others will differ here. Black Horse Blade is also superb. Lovely little ARF that just needs a few runs of cold glue ver the joints inthe wing box, assembly and you're ready to fly.
If you are no comfortable with a tail dragger, then a Phoenix Models Tiger 2 or 3 is superb or one of the Black Horse tricycle gear planes like the Travel Air.
Any constant chors, semi symmettrical wing ARF with longish tail moment will be great. Bi-planes tend to have short tail moment which makes them a handful in the landing pattern, steer clear for now
