Ryan B 04/20/26: Where to buy this pipistrel alpha trainer Castle nut remover 1 1/2 inch?
Michael Sawyer 04/21/26: We received axle nuts with the purchase of our alpha trainers so we never had to go shopping for one. Our wheels are Beringer Aero. The best route would be to verify your wheel manufacture. Then contact them. I did a quick search trying to find one like ours. This is as close as I got (Pipistrel Alpha Axle Nut). I’m not in front of the aircraft right now but M25 (this socket) is roughly 1 inch in Thread diameter. Did you measure the ID or OD of your nut?
