H-9 P-51
I have 20+ flights on my H-9 P-51. so far the only peoblem I had it nosed over on roll out after landing, the right landing gear
collapsed. My plane is powered by an O.S. .91 4 stroke with pump
IMHO it could use a little more power.
I have the steel bolts in mine, no problem so far.
happy flying..........fwc
