I am plannng on putting a shim on my stabiliser while I learn.
I was thinking using various thicknesses of O-rings.
This is will be trial and error... In search of a short cut
What should I be aiming to achieve?
A 3 degree angle change less or more?
I realise that the length of the fuselage on a different setup to mine will be a factor but some knowledge will be better than my vacuum
So, can anyone who has done this fill me in on what you used and how you setup each change or did you trial and error?

Thanks
