Both the Showplanes and James cowls require a prop extension. I've been going back and forth between Aerosport Power and Whirlwind to make sure everyone is ok with this. Now, Whirlwind is balking a bit at mounting their new 3-blade prop on an extension. I contacted the manufacturer of the extension, Sabre Manufacturing, and they said they make a 3" extension used in Red Bull races with 60lb props pulling 10 G's. They don't think this is any problem for me.
I understand manufacturers being hesitant to endorse ANYTHING GOES, but is this a real road block, or just the reality of Experimental airplanes and new combinations? I'm not EVER going to do anything close to the Red Bull guys, so I can talk myself into this. On the other hand, I have no desire to really approach the edge of safety and wisdom.
Anyone with prop extension experience have any perspective on this?
