Hi Guys and Gal, Please give some thought to this. The "E" head in a fairly heaver head. All the parts are what I would call a grade size up from the 500. I do have both, EXI 500 Its full CNC metal and it is not as ?heavy duty as the Smartie. Remember that the "E" swings 550's and the 500 only swings 430's I think I need to see what size feathering shaft the 500 has!
Any way just my thoughts...
Blade mSR, HBK2 Xtreme
EXI500, HDX500, Esky 900
E-Smart CF Pro, Full Metal E Smart, Outrage 550
