RE: Hope for Scale Props for SPs
Andi,
I just bought the VarioProp 16D 3-blade hub with 18.6" round tip blades for my TF Corsair. I used a slightly different method of marrying the hub to my 120SP. I designed a spacer to fit behind the hub, with a 12mm dia. flange to fit into the back of the hub. The setup works great. I set the pitch at 12" and ground tested it today. The 120SP turns the prop at 4660 rpm. As with your hub, mine got pretty hot but the blades were fine. I believe we've found a winner here and this hub looks great!
