os 91sx-h for pattern
You should be able to use it just like any other reliable sport motor. It likes 15%-30% Nitro and for Pattern perhaps a 15X10 prop.The question arises what type of an exhaust system will you use as this engine is more powerful than the 91FX but still might benefit from a stock 91FX exhaust system other wise your looking at a pitts style or tuned pipe.
