Propshaft was a 2mm from either CMB or Model Boat Bits - bought 2 and cant remember which is in which boat
Rudder I made myself from brass rod, tube and sheet.
The prop is another story! I wanted to set the shaft angle as shallow as possible for motor clearance, so set it up with a 30 mm prop before I applied the bottom skins. When the model was finished and I was ready to re-install the shaft and prop, I couldn't get the prop on
I have had to fit a 25 mm prop, but I think it may have contributed to the poor performance on Sunday. I may have to modify the bottom skins to allow me to refit the 30mm. The motor is an MFA 140 on 6 volts.
