I have a saito180 in mine. No firewall problems but within about 10 flights my elevator hinges broke (2 out of 3 on on side) I was wondering why I had to keep retrimming elevator on that flight. Not sure if CA hinges are the best on those huge control surfaces, however I do always use to much CA when installing, just can't help it, the bigger the glob the better job (not). Do you want to buy one??? Only 10 flights on mine. By the way my tank is mounted over CG with perry pump on motor. I did this at the start, mine has a 24 ounce tank and that just seemed like a lot of weight up front when full. Nice flyiing airplane, I just have to many new projects going, need to free up some money to finish a couple other planes that are on my pool table, since my hobby room is full.
