I'm currently assembling a Goldberg Ultimate 10-300 ARF and have a question regarding engine cooling. I'm installing a Saito 100 FA in this plane. Other than the necessary cutout in the cowl to accomodate the cylinder head and muffler assembly I'm not confident that the engine will receive suficient air to be adequately cooled. Should it be necessary to make additional cutouts in the cowl for additional airflow? I'd appreciate some feedback from experienced modelers who've dealt with similar engine cooling issues. Thanks!
