I am introducing a = question from a friend=20 , who doesn't speak English,owner of a Lancair 235. He changed his = engine=20 ,installing a Lycoming O 320 D3G in lieu of the O 235.

The propeller for the O 320 D3G was = initially a=20 three blades ,constant speed ,made by Arplast,but he is having some = problems=20 with it , as it is a prototype.

He has the possibility to get a = Hartzell=20 propeller,type HC-C2YL-1BF,coming from a Lyc. O320-D1F and asks if this=20 propeller can be cut to 70" and fit his

L 235/320,cruising at a mere = 170/180=20 KIAS.

Has anybody some advice about that = problem?=20 Waiting for reading from you , propeller=20 specialits.

I recently put a MT 3-blade prop on my=20 235/320. It has a built-in 4" extension and fit = perfectly. =20 It=20 is 63" in diameter and I feel that the ground clearance is = minimal. =20 Remember that the 235 airframe is closer to the ground than the = 320. No=20 way would I put on a 70" prop.

With a prop=20 as short as mine, I was told that a 3rd blade is necessary to handle the = horsepower of the IO320.

Bob = Belshe

I am with Bob on this one. I have 64" = prop on my=20 235/320. With this prop, and the nose gear strut pumped up a = little extra=20 (3" showing), there is 8" of prop to ground clearance. With a 70" = prop,=20 there would only be 5" of ground clearance.

That is not good.
