By golly, you're right! I just went out to the shop and took the prop adapter off the 28-30-950 motor in the GP Electrifly D.VII. I didn't realize that there was an existing groove near the end of the shaft. My face is red!
I'll have to measure the depth of the prop adapter. Wouldn't want it rubbing on the housing.
