Been doing some research and it seems this servo is the best for the flipper motor:

Should I get it instead? I would like a powerful flipper, but don't want to go into pneumatics

those are a bit heavy at 20g but may people use them get the £14 version much better. there are other good servos like the hitec mg2

sparkey: wtf?

I'm not that concerned with weight, as I'm not entering any competitions.

Would sellotape work as a hinge for the flipper? If not, what else could I use?

An actual small hinge?

Badger · « **Reply #47 on:** July 22, 2011, 05:15:54 PM »

No, I'm thinking of attaching the flipper to the main body with sellotape at the top, as a kind of hinge. Would it work?

And I presume I glue the pieces of polycarbonate together with superglue?

SKBT · « **Reply #48 on:** July 22, 2011, 06:10:14 PM »

No and no.

Superglue melts lexan. (I don't know why but it does) and you can attach the flipper directly to the servo and use that as a hinge.

Badger · « **Reply #49 on:** July 22, 2011, 06:12:38 PM »

So how do I connect all the panels?

And I'd MUCH rather just have a hinge at the top and let the servo push it up.

SKBT · « **Reply #50 on:** July 22, 2011, 06:21:46 PM »

Connect them with a polycarbonate/lexan safe epoxy or screws. I recommend screws so you can repair/modify it easier. If you really need a hindge you can get one at a craft store or home improvement store but if you want some kind of tape you should use gaffers tape or a similar type anything less will probably be too weak or not sticky enough.

Badger · « **Reply #51 on:** July 22, 2011, 06:24:51 PM »

OK, so gaffer tape. Epoxy would probably be easier to apply, don't need to drill holes.

No, you will need to make a hinge

Anyway, it would be probably to try and make these an AW, I would seriously consider the benefits of it
- You get to compete with them at proper events
- You get free entry to proper events
- It's more fun

Badger · « **Reply #53 on:** July 23, 2011, 02:37:00 PM »

What I'm planning on is trying to make it an AW with the stuff I'm getting, but if I can't get it to 4"x4"x4" or it is over 250g, then I cba to re-make it.

Gotta be within 150g, FYI

How would I attach the body panels together, with the lexan glue?

haz · « **Reply #58 on:** July 24, 2011, 01:01:53 PM »

fold and bolt, or hot glue.

Vertigo · « **Reply #59 on:** July 24, 2011, 01:08:07 PM »

Yeah, what haz said, although I'd use HDPE myself
