YC-14 Bomb Bay Doors

So this little simple job challenged me the most so far.

Getting the servo operation to function well on the bomb bay doors is hard.

Right now it is close but lots of noise from the servo so I’ll have to tend to that.

Enjoy the video.

Part 1. Gut the YC-14.

Removed all the old full size servos and gear.

Along with the old single egg bucket.

You can see the huge difference between the full size and 9G servo!

Empty slate.

I made the 4 egg hopper to the same inner width specs as the YC-14.

So it should squeeze in there very nicely.

Only minor cutting required. In fact the new hopper is pretty well the same size space wise as the old setup including the servo mount for the bucket.

Onto the bomb bay doors. For days I’ve been trying to come up with a plan.

The lay out eventually presented itself. 5″x7″ piece scored along the underside glued to the body.

Fold and tape.

For now the quad hopper is just placed in position.

Early on I tried some rubber bands to open the doors.

They did a nice job but turned out I did not need them.

Micro sevo working very hard.

Doing some tests.

You can see the arm is long. This is part of the key to balancing the setup out.

Open.

Closed.

When closed I do hear a lot of servo chatter.

I’m still messing with the mount.

But over all this seems like it will work nicely.
