Hello Steph,

Measurement, I will let you know more as soon as the engines start to get loose after a few flights, note this is with 30% nitro, not 25% as recomended. On the next flight I will get you exact numbers, as once the engine is set the first time there is no need to recheck RPM, and the RPM increase with flights.

Christophe and Benoit have been flying with the 175 for over a year now I think, they can give you exact numbers as they tried the engine from the start I guess, I will give them a call if I were you, they might know more about the new coming prop.

Regards

Alejandro
