I've spent about three weeks so far trouble shooting what should have been a one-week assembly. It may take me a a few more days to make all the changes and get everything set up again.

One other thing I've just noticed is that with the Saito 72 mounted inverted the carb is about an inch below the level of the tank centerline. Is that a problem? I'm not sure I see any solution to this other than just mounting the engine upright.

After I've got all the ARF-bugs worked out, I'll need to give the engine a careful break-in (attached to the model) so that will mean a couple of more days probably. But hopefully within the fortnight, I'll be able to get'er up into the air.
