The tank is planned to be mounted in the right wing bay, hatch accessible. However, I do have a preproduction running around with the tank on the opposite side of the engine where it can be seen. It really does not matter where you put it, the characteristics do not seem to be changed by the tanks location. I am still having log in problems to rcu so if I do not respond to these posts, it is because the system is not allowing me to log in. Feel free to email me at [email protected] the kit is now available from Morris Hobbies. Those of you who bought this kit and need help with setup send me an email. Jeff.
