Got a question on how to mount the gas tank on this plane. I got mine together ready to fly but the instructions said secure the tank in with the supplied rubberbands. Mine didnt have any rubberbands in it. I did put the receiver plate thing thats suppose to help keep it in place but thats all thats currently holding it in spot and dont want to rely on just that to hold it in spot because I had to trim that to get it to fit right so Its not as strong as it was. Anyone else run into this when they were assembling theirs?
