Yes, I have had that happened to my V4. It is just random if the helicopter will work or not. Your Tamagotchi might use the controller wrongfully and crash it. But it will still be in your items list.
ive seen an rc helicopter in the lucky tama toys shop in the v4 tamatown but i never bought one so i never had an rc helicopter that crashed, my friend had one ill ask her is her's ever crashed
