Wait a minute, guys...

That is a skinny-eared A5 30p chopper. That blade shape may NOT suitable for making true a copy of the Lightning ET. 22 thru 28 pitch A5 is the true 5" wide "big-eared" blade profile that the ET's are cut from. The only 30's that can be made into a true ET copy are the later A62 Chopper II's with the Flo-Torq hub.

The skinny-bladed choppers make a good candidate for the Yamaha-style cuts, however.

Tim Hackney cut a "small ear" 26P chopper down for me into an ET cut. It works just fine. It's actually a little quicker off the bottom than the 14.5" versions. The blade geometry is almost identical to the larger version only the diameter is smaller. So it CAN be done with no problems if the right man does it. The only negative I would say is the original blade thickness is less so it can't stand as much "Knicking". I would think that the prop being a 31P may be able to benefit slightly from the cut down in conjuction with the smaller diameter. It would of coarse depend on the application you run it on.
