Hi everyone, I am having some difficulty with my new Great Planes Escapade 30cc ARF kit specifically to do with the engine. I bought a 35cc RCGF with the rear exhaust and carb and I'm having some issues with the spark plug boot. I have mounted the engine and the ignition as well as setup the throttle linkage and choke. The problem is the plug boot doesn't seem to be mounted snug enough. I have not run the engine yet but I have no doubt that the vibration alone will vibrate it right off. It is definitely seated all the way but I know that it will not stay on. Also since it is mounted with spark plug pointed down, gravity is also working against me. I have looked on the Web on several different sites and have not yet seen a good fix to my issue. I have found one link that suggests I should modify the casing and put a screw clamp on it but I rather not have to cut up my new setup. I am hoping that someone has a better idea for me or at least tell me that the fix that I described above is the only good solution so I can feel a more comfortable doing it. Any suggestions would be greatly appreciated. Also real quick, for a plane of this size (80 inch w.s.) and for someone who is not the greatest flyer, should I go with flaps or no flaps?

FYI, This is my first giant scale rc airplane and I want to make sure that I have the best possible setup for the plane and for my flying skills which are mediocre. So here is my setup, if there is anything that you think I can improve on or just change completely please feel free to let me know. I have not installed any of the servos, receiver, batteries or gas tank yet specifically because I wanted to hear from some seasoned flyers first. This is not like my other cheaper planes or my other rc cars and trucks. If I screw up it's going to very expensive. Your suggestions would be much appreciated.
