Les I am trying to figure out the tank situation. Becuase the carb is right up against the hole in the firewall that would secure the tank normally I am looking for different ideas on securing it. I am also mounting a 10oz sullivan for the smoke system I have put together. I'm thinking of moutning them over/under styel and wrapping them in foam. Looks like they should fit in the area just behind the firewall. Still working that out. I'm breaking the 30 in on a 18x8 master but hope to run a 20X10 once it's finished breaking in. Should have more than enough power. I don't fly crazy so it should provide scale flight looks and performance.
