Rob, can you just cut out what you need from the mount PLUS move the cowl a little forward to get the space you need? It's ok to be a little long on the nose. I don't think you will hurt the mount badly if you cut a little out of it...look at the cheap two piece mounts usually given with many ARFs...they work when I have had to use them. Just a thought. I have a YS63 on my Stinger II. It must be shorter than the Saito, as there were no issues getting the distance to the prop washer needed. My Stinger sings with this engine...very quick, loads of fun. Get r done! Jon
