Ah, you have a copter and a quod? I have a simple up down, left right self stabilising type copter and my Hubsan X4. I've tried a simulator of a copter with my controller plugged into my PC and it was so difficult to control.

My very similar kit had a "remove seal after washing" sticker on the piezo speaker.

There is another piezo in the kit without a sticker on it and looks the same as the stickerfied one. So maybe there are 2 piezos.

In mine, the one without the sticker is a buzzer.

I should look at what is actually in the contents on the Amazon listing. No instructions or anything with it.

Mine neither!
Sainsmart have tutorial documents downloadable from their site though.

Mine is made by sintron, they seem to be pretty much the same as the sainsmart kits, but they ask you to email them for the documentation. They don't bother to provide an email address though :/

The one that needs washing. It's easy enough if you think about it.

That's awesome!

I didn't get much this year, just some graphic novels and a headset for my pc & ps4

:) ace biscuits.
We had a mostly great christmas, marred only slightly by my sister in law walking out in a huff just as we were serving pudding. I only asked for cash to go towards a new drawing desk, but got some mead, posh honey from Italy, CDs, A peanuts book, and loads of nuts/chocolate combinations too.

What was the walk out for?

Cool, I'll have a look on the SainSmart website when I get a chance. Not much use if they don't give you an email address but expect you to email them.

I'll have to find something I can practise soldering on before I try it on something in want to use. I have a kit from my birthday, a crawling bug that needs soldering too.

So... something you can use after washing it and removing the sticker? Is the sticker protecting something inside that can't get wet when it is washed? Is there a mogwai inside?

I think one is an active buzzer and the other is a passive buzzer. Not 100% sure about that though.

I read a nice tip on soldering a while back. Got any really old electronics? (radios, VCRs etc?) practice on them, desoldering and soldering parts.

I have a YouTube video bookmarked to watch when I get around to doing some soldering. An Australian guy who makes it look so easy. He recommended not using the pointy tips that come with irons but a wedge shaped instead.

I've got loads of stuff up the attic I can pull apart and try soldering with. Possibly some unsoldered points on circuit boards too.

Also I had a motherboard chopping board for Christmas :D

I can't solder unless the tip is really pointy.  I have one iron that is a split wedge and it forces you to learn how they suggest you do it because it won't turn on unless the solder is in the split.  The iron quickly earned backup status!

Not sure I've seen one of them.

Here is the tutorial I watched, if you're interested http://youtu.be/J5Sb21qbpEQ

I also had some cutters, solder, solder wick, tweezers, soldering mat and a stand with magnifying glass, light and arms to hold things.

Gone?  :-B

Christmas was like that for me last year. Depressed at being 50 and out of work. No one wanted a 50 year-old. I just wasn't into it last year. Shouldn't be like that (my lack of spirit) I grant you, but I am only human (others do not agree). This year is a whole 'nuther story.  :-O~~~

Do tell.
