I finally got my battery delivered and wired up to run the BB.
If I push her under initially, she gets all the air out and will then trim quite level. If I just put her in and dump the air, she sinks stern down and the tip of the bow stays dry. The air vents in the bow aren't big enough. This is why we do trial runs aye? If everything was perfect first up, we'd get bored. :roll:
The micro servos that I used, were ones that came with a radio from Hitec and aren't gutsy enough to drive the planes and rudder. It will move them slowly on the bench, but not at all under any load. I'll have to lash out for some high torque ones. I've got the linkages working as freely as I can and I think they're OK. I set the rudder at half starboard for the test and vid so she'd go around in a big ark. It worked OK. The people watching didn't notice that I wasn't steering it! I tried hard to find a spot with no hecklers, but they showed up. Always the way with subs aye?

Here’s a 5 minute video clip and slide show on the testing.
