White Rose Engineering is now offering 6.3 oz nose weight prop washers for the DA 50, 60 & 70 engines. We can face off the front of the 6.3 oz if you need a liter one at extra cost. The prop bolts will have the same purchase into the prop driver as you currently have with your DA supplied prop washer. The SHCS's are counter sunk into the heavy washer.
