Dave,

Should I put a YS 110 or 140 sport in my Funtana 90. I have seen my friends 140FZ shake the airframe on a Dave Patrick Ultimate a lot. If the 140 sport shakes that much I fear it shake the light airframe apart on the Funtana. Finally, I have had a difficult time on the availability of either of these two engines. Can you provide any information on their availability?

Regards,

John
