Bell 47 in progress

I am working on a project and am in the process of putting together the Bell47. I am working with the 1/35 MRC kit. So far no complaints. I havent made it off page 1 of the instructions. The Robinson(i believe thats the engine type) is a mess of cooling/intake hoses. With what limited reference photos I was able to gather I am kind of winging it on some stuff. O'well. I doubt there are any 47 mechanics from the Korea era on this site to chew me out. The biggest complaint to this point is the damn Tenax I'm using! Does this stuff expire or something? I mean I have used the stuff before but sheesh.. this bottle is weak. Whats your favorite glue of choice? I figure when building helicopters you need the best glue available. Rotorheads often have lots of small tedious parts that need to bond quickly and true. I'm open to suggestions on rotorhead tricks and tips you all have learned along the way. I will post some pics once I get past the engine. ITs rather crude and mundane.
