<DIV><SPAN class=233513912-23062003>Yes, I am using the YS 63 on a Morris
Hobbies Knife. The recommended prop is the APC 13 X 4W. The W is for
wide describing the characteristic near constant chord of this prop. Since
speed is not a goal with this type aircraft (in fact speed is a no-no), the low
pitch provides exceptional power to maintain hover and achieve good vertical
acceleration when contrasted to a higher pitch prop. The YS 63 is truly a
remarkable engine for this type flying.</SPAN></DIV>
