Randy,

I have a ST .51(new style) that I purchased from you a few years back.
I would like to use it in a new Strega(Windy Urtnowski design) that I am building.
The Strega has a 724 squares wing area and designed for a .51-.60.
Does your modified .51 have enough power or should I use my PA .60 or a ST .60 modified for stunt.
Please advise.
Thank you,

Thank you sir.🇺🇸
