so this is the ose flexshaft i bought back when i setup my pursuit .

question is : aside from moving the drive dog back a bit is there other shafts that offer longer threaded area? you can see this prop is barely holding on . yes i used some loctite on the nut but still isnt optimal .

looking at the flex picture you can see this isnt a long shaft .i doubt i could move the dog far enough . i guess i should try .click pics for bigger view
