Prop and cowl are on, tho I don't have a spinner. Idk why I'm the only one this has happened to that's what makes me think it's a defective. I have 2 5s 3000mah lipos I got from a guy in the club for next to nothing, but I bet I'm going to have to go with a 5000 for the weight. I may loose the tailwheel also and the servo gear to help.
