I am just getting round to selecting the prop for my 360.  Could someone
advise me what the realistic maximum diameter is to avoid trimming the
tips every time you hit a bump on the taxiway, or brake hard?  I have
heard various figures from 68 to 72 inches, and would like to know what
other people's experience is.  I am looking at a 71 inch prop as one
candidate.

Also, can you increase ground clearance by putting a small spacer
between the nose oleo and the nose gear fork, or does that introduce
other problems?  Thanks.

Jerry,

 

Many Lancair 320 flyers use a 70 Hartzell CS prop without difficulty.  The TK5 shocks allow the mains to settle a little lower and that results in a bit more clearance.  Sure you can put a spacer to raise the nose a bit, but then you must control the landing speed so that the three point attitude doesn't send you back flying if you land too fast.
