Ok, is there any way to replace the main shaft without taking everything apart? I figure there's not, but maybe someone has a faster way?

Also, I have those plasti-blades and they work great, but im not sure now if i'd rather replace blades or main shafts....

I hit my plastic garbage can and the blades didnt even scuff but my main shaft is bent....

So I may just stick with the cheap $8.00 heli-direct blades and tape the ends...
