Hi Randy;
I am building a Ziroli B-25 and want to purchase a couple of Ryobi's for it. I hate to drum up bad memories but...........

could you tell us more on what happened so as I do not repeat the same mistake. Were the engines powerfull enough?. How was the climb out rate? or did you get that far. Looks like you did a great job, my hat is off to you. Thanks again
Peter.
