Hi Todd,

I understand, actually his airframe is a bit more draggy than an RV.= =C2=A0=20 However, having said that, Max informed me he had talked to IVO and they=20 suggested the try converting his IVO to a two bladed version, they indicate= d to=20 him that would interfere less with airflow into his cooling inlets.

Tracy Crook tried an IVO prop many years back and came to the same=20 conclusion as you, it was great for take off and climb out but he hit a =E2= =80=9Cwall=E2=80=9D=20 around 170 mph and he also noted it interfered with cooling as well.=C2=A0= =20

Hi Ed;=C2=A0=20
=C2=A0=C2=A0 I actually wasn't thinking that these would be very i= deal for=20 Max as I would have expected his airframe to be similar to an RV airframe. = I=20 would expect that He would want the deep pitch version like I just switched= to.=20
