I'll start to cover my plane soon with solartex white and I think that I'll make a try to cover the wing fillet with solartex also but that is a try yet.

Zpat,
Why did you have to rip of your covering that you made?
For the flattener thing can I use talc and my tiny airbrush (0.3mm) and not clog my brush?

The filling device I found out the www.slimlineproducts.com has them and I found a company in England who sells them but the shipping is very expensive from there. I was planning on using the hole that the top plug shall be (at least on my drawing there is a plug on top of the fuselage) but some says and the information that slimline has on their homepage say that the fueler device is not good to have if below the fuel tank position. But they have an option to use the filling tube and plug another with a t-tube on the exhaust tube the retrieve the excess

GBZflyer,
How are your experience with your saito 72 on your plane?
