Wow great minimalistic project:-)
What about adding a part list in the first post ! :-)

Also can someone post an "European transaltion" for the glues? .
White glue -> vinilic?
5MIN Epoxy OK
Polyurethane Floor Enamel ?
polyurethane (pu, gorilla) glue ?

PVA wood glue = white glue
PU floor enamel on oil base = floor paint
PU glue = PU glue
the latter is hard to find nowadays in europe if you are not working in the industries
Search ottocol titebond gorilla pattex construct sedal just to give few examples.
Ask your local carpenter maybe. He should have some for sure.

I have been using this "polystyrene glue"http://direct.hobbycraft.co.uk/produ...lue_286252.htm it has been holding well so far, it smells almost exactly like PVA glue so I may try some PVA on foam to see if it works.

yes. i found several pva types at art stores and craft stores. while they are ok for paper and wood i found little advantage for foam, cf, or plastic. imo pu (polyurethane) cannot be beat for adhesion and strength. the water foaming trick is specially useful where weight is important. like in these micro quads where its the single biggest factor in handling and flight time.

btw inspired by midelics lashing link i threw together another dquad (short for diy quad, notice i named it couple weeks ago. pronounced "dikwad" lol!) using nothing but bamboo and rubber bands. no glue, wood, or paper tubes at all. amazingly took less than 5 minutes to build. it aint the most rugged one yet but flies really well and does weigh less than any so far. if anybodys curious ill take some pics.

that is the plan. but im waiting for the ali motors to come in (hopefully with 1mm shafts) and also the v939 boards which weigh much less and are cheaper. in fact im convinced its possible to get cost below $15 total if these work out. speaking of which more recent reviews, unlike previous, were very positive. this gives me hope that buying 3 of the v939 controller boards was not a mistake.

Dickwat??? I hope you are not insulting me.lol!

Throw us some pics please. I'm curious.In fact I was thinking the same about using rubber strings for lashing.I found some special strong(flexible but no elongation) rubber string which is suitable for lashing.

Can I use 0.15mm magnet wires to connect a v929 motor to a v929pcb ?
Or should be 0.3mm better according to the amps the motor uses?

Based on SS-red, SS-orange data,
I guess these motors should draw a current around 0.4A with ladybird DD props
I would say 0.3mm is better - see this chart (scroll down):
http://www.powerstream.com/Wire_Size.htm

But... anyone who has conducted tests can correct me (...remember I'm still waiting for my motors to arrive - this is a projected guess...)

Hmm seems like I'll have to do some more reading about electronics I figured it was the right part because I typed the numbers of the component I saw into digikey and that's the most similar search result it returned (the component said 00BF on it). I'll see if the little transistor in my old picoo z will work hopefully it won't burn up or anything.

Here are some pics of my quad. Same basic concept except mine is held together using loctite super glue. I tried making one out of some balsa I had laying around but it ended up being heavy and the legs weren't at perfect 90 degree angles so I ended up with this. I used the motor holders from my ladybird as motor mounts they are 7mm so they should work with the s107s that I plan on ordering. I weighed it on a weight watchers scale accurate to 1 gram (most precise scale I have access to for the moment) and it said 4 grams so I think it's safe to assume it's somewhere between 4 and 5 grams. Can't wait to get it flying! I have one question though, are any s107s or equivalently powerful motors confirmed to have 1mm shafts? Someone else mentioned that there should be a parts list in the OP and I agree it would be very helpful as there is some very useful information scattered throughout this thread.

that is REALLY cool. if i didnt know any better id think it was one of mine.

and yes, i would put up a list except there are a few unknowns. regarding motors the s107 are known to work but have .7mm shaft. not a big problem but does need some glue in the prop hole. aliexpress motors linked to earlier (search) are theoretically available with 1mm shaft but initial tests by mystman show may not be as powerful. i wont be sure until trying them myself and there may be an issue with actually getting the right shaft. walkera, udi, v939, and other quad pagers shine in both departments but are expensive:

for now cheap, 1mm shaft, powerful... choose 2.

this may change depending on what shows up in my mail next few days.
