I have a 117 with a C90 engine. Performance can vary according to the prop fitted.
I've jumped through all the required hoops to get approval for a Hoffman prop.
Properly trimmed, it's giving me 100kts @2200 RPM. ROC is down by around 50 fpm but take-off roll seems unaffected. (Less than 200mtrs).
Fuel burn is around 15-17ltrs per hour.
Croqueteer. The slightly rough running at 2300 RPM could be due to a slightly rich mixture. Try leaning it off. If it smooths out then it probably needs the carb adjusting.
