Nahhh. Loctite and a press fit is fine. For that matter the press fit would be fine too. If you ever tried to remove a prop hub from the crank you will trust the Loctite. Takes near 400 degrees of heat to break it free. Been there. Nothing near that temperature in that area. FWIW I use the 620 Loctite for hubs. Expensive but a small bottle lasts a long time. A little on the thread and a little on the crank and thats it.
