I just wanna thank all of you for taking your time to help me out, your advice and wisdom in my opinion is invaluable, I love this hobby and appreciate the friendlyness of most involved, I will epoxy some Tristock behind the firewall, which I have, I have already placed 1/2 foam on the sides of the tank as it already has a peice on top and bottom , but 1st I will need to reposition the stopper so the tubing matches the manual update from Tower.......Then I may use regular epoxy on the bottom of the fuselage as it is very weak and bows when I pick it up, the 1st NexSTAR had a hole in the bottom from the factory so I know they are easy to poke through........Happy flying this summer to all and thanks again guys for all the advice......
