Well I should have just added this with the other question. Were can I get a few prop nuts and maybe a flex shaft or two. Just in case something happens?
Try looking on e-bay thay have some good deals on there sometimes. I have got some flexshafts from there and got a good deal on them. Just watch the shipping prices on there.
Prather and Octura both make good props nuts. I place a small picece of fuel tubing between the prop and nut that helps to hold the nut on. I've yet to lose one during running, just a few lost in the grass.
