Depends on what look you want for your next plane. Do you want a high wing or low wing? Do you want a trike gear or tail dragger? World models makes some nice planes. There are sport scale warbirds that fly well such as the T28 and it would make a good second plane if you can get a flight or 2 with the buddy box. It has a trike gear and is a low wing. Phoenix Decathlon is a good sized plane that is reasonable price, flys nice and is fairly aerobatic. Its a high wing with a tail dragger setup. 46 sized planes are decent price and big enough to see easily. I would buy an OS 46 AX engine and use an APC 11-5 prop. Its the best engine in that size range imo. A Super Sportster is a plane with a wide speed range or if you want a plane with a mid wing mounting a Sig Mid Star is a fantastic flyer. [8D][8D]
