The secret is to tune them so there is no hiccups.
The one I saw flaten out a tru-turn spinner was my first Saito 72 just like yours before I owned it. It has always run fine for me with no backfires

Maybe using a spinner; of any type, should not be recommended on four-stroke engines...
If they destroy them on every hiccup...
This hobby is expensive enough, even when you don't need to replace torn-up aluminium spinners...

Thank you w8, I'm relieved because I think an engine is naked without a spinner - depending on the aircraft.

Mine has never kicked back on me either.
I did find that if you lean out a four-stroke, it will initially slow down (giving you fair warning...); and only if you keep leaning it further, it could kick-back.
Why are we all warned to use only aluminium spinners? If it flattens the spinner anyway, why not use a cheap plastic unit (with an aluminium back-plate)?
