I also make sure I have a few of those nuts in the field box. That way, if I really torque one down with and strip it, my day isnt done. I use the blue loctite tighten-up threadlock. Its in a white tube. It holds great, but will let you break the nut loose without breakin anything else. Also, some of it will stay on the threads when you take the nut off, so there is some left when you change props.

Believe it or not, I feel like I have much better control over the plane by not using the starter on it. I was (and to some extent, still am) highly intimidated by the 1.50. Was nervewracking trying to start it, even with someone holding the plane. Everytime I tried to use the starter, it would kick back, or jump around when the engine tried to turn over. And I wanted to keep a hand on the top of the fuse to hold it. That got unnerving with the large prop. And until i can learn how to pick my nose with my toes, I kinda need all my fingers And I am nowhere near that flexible, and never intend to be. I still use my starter for my smaller engines, but since I learned how to hand prop it, I can do it quite easily.
