2K,

Those tanks look like they could be moved apart a bit because there's some decent clearance at the top... Try offsetting them and rotating the brass tubes to the outside.

The Kevlar tanks that Starto' and I both used are so tight that they were practically laid up inside a Stingray fuse to maximize the fuel capacity. The Jet Tech tanks need to have the fittings rotated such that the brass tubes are turned to the outside. Then they only need a small relief cut in each side of the lower servo tray to fit it all in and clear the fittings.

How are the plastic tanks mounted? Are they fastened down to some sort of structure or left to be supported by the lower skin?

Also of note, I mounted the speedbrake servo on the opposite side of its mounting flange, from underneath. I used an HS-645MG and an HS-225MG for steering. They JUST fit! I think the 645 gave me some clearance issues, can't remember now.
