Thats coming together nicely Steve, not much left to do ! The 2" bellcrank will be OK if the fuse. is wide enough for full travel, if not make one that fits. The leadouts should be as light as you think wise ( small model, small engine not too much line pull ), ditto the U/C, I used 1 1/2" foam tyred wheels to save some weight. My Merlin P.M. has a heavy gauge 8 mm washer epoxied under the stb. wing tip, while the full size Phantom uses a 20c. coin. I found that a narrow bladed 7x6 MA cut down to 6" the best prop for the Merlin on 35" lines. Tried 6x3's etc., but they didn't give enough forward speed for good line tension with the little diesel. Mount the tank centre line same height as the NVA. Just my findings with my Phantoms, hope this is of some help......John
