That would be a good combo. I've seen a couple of the Pizzaz
ARF's fly at our field, and they look very stable. Almost all my 2
strokes are the TT-46 & 36. Once broken in the 46 always starts
with a finger flip of the spinner clockwise. Strong power and no
dead sticks w/ A-3 or #8 plugs used after break-in plug. A good
friend of mine has the YS-53 on his hovering plane. With the pump on the engine it took a little work to get it set up, but once
right it has the fastest throttle response I've seen in a 4 stroke.
I think the only advantage of the 72 would be prop dia.
One choice I would offer is the TT Giles or Extra profiles. Huge
ailerons for better low and slow torgue rolls. My Extra jumps off
the runway and wants to climb. I'm using the TT-54 FS.
If you go Pizzaz or any box fuse arf pilots should ALWAYS use
thin Ca on ALL hot glue joints to make sure they are solid. Sometimes it take med. or thick to fill a gap. Too many post on
here of pilots saying their planes fall apart. And in the fuel tank
area I always slosh thinned 45 min. epoxy in the box and the back of the firewall. Have yet for a firewall break loose.
