It's reassuring to see your plane that has only 1/2inch ground clearance. My model has similar characteristics to your plane's undercarraige setup. So with confidence!! I will fit a 10/8 while still looking for a suitable 3 bladed.
Still some work to do on my Slingsby T67 FIrefly but I'll post a few photos when it's nearer to test flying.
RInging Weston is a good idea, only a National call for me over here in the UK.
