I mean models. The guy that trained me was always going a bit over the top about stalls which is what made me think stalls made the engine kill. I'd say my favorite maneuver is doing that 180 degree rudder turn when you drive the plane into a stall just before you kick over the rudder to spin the plane around. I can't remember what thats called. I've only been flying for a few months. Kinda ready to move up from the trainer. Ive got a Hobbico nexstar and my teacher sold me the engine with a 10x6 prop on it. The manual for the nexstar says use a 11x5 but my teacher said it shouldn't make a difference but it takes practically the whole field to get off the ground which is why I think i'm gonna throw an 11x5 on there to see if that helps except the 10x6 already mows the grass so that 11x5 is going to make a mess of my plane every time I use it
