hey guys any idea on the performance on a wood sensenich 7240 on a 65hp champ
other then a good climb prop
static rpm
cruise
anyone with any history on this prop
thanks rob

never mind its not certified for a 7ac

Actually it probably is... from the Type Certificate:

1.
Wood Propellers - fixed pitch
Models 7AC, 7BCM, 7CCM, 7DC
Models 7EC,7FC, 7JC
10 lb.
(-52)
(-54)
(a)
Sensenich 72C-44 (Models 7AC and S7AC)
Sensenich 72CK (Model 7BCM)
Sensenich 72CK-44, -45, -46 (Models 7DC, S7DC)
Sensenich 72GK-48, -49, -50 (Models 7CCM, 7EC, S7CCM, 7FC, 7JC)
(b)
Flottorp 72A50, 52 (Models 7CCM, S7CCM, 7EC, 7FC, 7JC)
(c)
Any other approved fixed pitch wood propeller which is eligible for the engine power and speed and which meets the diameter and static r.p.m. limits specified under "Propeller Limits" for the pertinent model.

Was thinking the same thing. Wood props are a lot more flexable in that they just have to adhere to the size and rpm limits in the TCDS then they are legal.
