Hello Steve,

The engine I use is the OS 120 AX. I'll use a 16x8 prop. Glad to hear that the 108 already has good power. I sometimes hear that a 180 Saito or at least 160 OS is to be used. So I'm confident now that the 120 AX will be good enough for me. I'm training now with larger tail draggers to get used to the take off characteristics. Thanks for the advice, and I'll give feedback as soon as my 109 got it's maiden.

Regards,

Eric Schumacher
