the wasp stings!

Tasty,

Some red wine and a tentative test flight, wow!  what a combination, my new Delrin 'integral' Wasp 250 frame, at last, it's in the air tonight!!
Under da hood ;-)


My now customary light fixing:


Front ender:


Mighty meaty!


Down with it:


Up with it!


This is my first Naze (acro) and I found it very easy to configure (Cleanflight), coming from the CC3D, how did I find it?  well, I've only had her in the air for a minute or two, but, I think for out of the box precision, the Naze has a distinct edge.  It seems unfazed by ground effect, and hovered happily a few inches in the air for me to get a pic of it in action.
I'm a little unfamiliar with the modes as yet, but so far, I have tried angle, horizon and the dreaded acro, all without incident so far!  Acro didn't appear as radical as the equivalent 'rate' mode of the CC3D, but as I say, it's early days, but hey! she's a go-er by any means, begging to be flown to near destruction!

As pleased as I am about the general design characteristics, I've already noticed one or two things that need a tweak, mainly to do with the camera positioning and fpv cam provision, which I have not really given as much thought to as I could.  Still, they can be modified with a simple redesign of the top & middle plate, not by any means the end of the world!  Agh, the tribulations of the 'beautiful game'!

That looks sweet mate, I really like it. I see you';re using those plastic motors too.

[bazzerh]

nice design andy, does delrin come in funky colours too?

What?  ';White hot'; not funky enough for you baz?   

Answer:  ppppossibly!

[flybywire]

Cheers art, yes, they work surprisingly well, nice sound at any rate!  I';m hoping that this frame will be able to take some reasonable knocks without causing total rebuild, which is a real pain, and the reason I hate crashing so much.     I';ve dropped it onto a hard floor a few times and it simply bounces, so the signs are good.  I';ll be taking it through the ';arboretum'; at work as soon as nobody else is around, trees galore in there.

That delrin stuff is supposed to be pretty tough. I';m using the material on the three plates on my miniMax Hex.  It doesn';t have to take strikes, the frame does that, but even with a few "unplanned landings" they have stood up very well indeed.

The white looks rather good from the pics.   Whats the AUW?  It must be a tad light

That';s a good Q Danny, It was all a bit rushed last night, not even sure where the scales are ATM!  It is pretty light tho, I';ll get it weighed up later on..
Yes, Delrin is mega tough, the piece of 3mm sitting on my desk has been bent around like billio for the last few months, without any stress marks appearing, so I think it would be real bad luck to break anything frame-wise.

I can';t get used to how tough it feels, I';m using a combo of 10mm plastic spacers, but gone ar e the plastic 3mm bolts, I';m now using a combo of 25mm ally stand-offs and steel hex bolts from HK.  NAze & PDB are held with plastic';s as per normal.  Can';t recall where I got SS hex bolts from that hold the top down, but they look cool I think.     Props are diatone Ghost 5x3';s in a nice fetching transparent alien green.  Cheap as chips from BG.

Sooo, I need to finalise the GoPro cam mount, make sense of some kind of mount for the fpv cam.  I could use output from the GP/DYS, but as you know, there is a lag which is totally counterproductive with close quartered flying.

A little more about the Naze; forgot to mention, I';m using the Default PID tuner, Multi-Wi stylee, but may try something else once I get her out in the open, probably try the luxfloat.    

[flybywire]

Further mulling over, and specifically for the needs of a friend who is interested in sharing the Wasp experience, (at last a guinea pig!  ). I have added a bracket and some slots to take the board cam where my GP style cam was designed to go, as they have a Mobius to sling on top, so i';ve added a 6mm hole (where i think it should go!) to take a tripod mount bolt for the bracket.  I also shrunk the cable access holes a tad, oh, and modified the cam plate to make it more universal, as i notice one of my board cam';s has it';s lens mounting holes vertical!  Hey ho!




Awaiting the suplies!



Also..i';ve just thought of a way i can retrofit my existing plates, by using the sheet of Delrin that they were cut from as a register..

[flybywire]

Ok, so my guinea pig er, mystery Wasp enthusiast (who isn';t called arturios, of course) has requested that provision be made for a mobius camera on top, mounted in the traditional Cornish way, using pasty gristle, or what are now more commonly known as ';rubber ball gimbal mounts';,  http://www.ebay.co.uk/itm/30-x-Anti-Vibration-Rubber-Damper-Ball-for-Gimbal-Gopro-Quadcopter-DJI-Camera-/331475092841?pt=LH_DefaultDomain_3&hash=item4d2d748569 in fact rather as my original v1 Wasp started out with, until I lost my Mobe!   

Here';s a jpeg render of the ';final'; cut, complete with all the mounting hole options I can conceive of, and also cram on to the beast without leaving it looking like a Swiss cheese.     I think he';s going to like it, if he was called arturios, which of course he isn';t.




Well, I h-o-p-e it';s the final draft, can';t really think of anything else, without redesigning it totally, as in the broom-handle-head theory, so with any luck, if the material turns up end of the week, art...er I mean Mr mystery Wasp enthusiast could be in the air very shortly after..!  Watch this ever increasing space!!

BTW, Did I mention the titanium dome head hex nuts that were winging their way from HK global?  No? 

Plus, in the fullness of time I may, at my leisure (and in a completrely nonchalant way of course) substitute the bottom spacers/bolts with these dandy accessories: http://www.getfpv.com/accessories-75/parts-hardware/m3-anti-vibration-sandwich-mount-set-of-6.html

I cannot deny or confirm that this Mystery Wasp Enthusiast who may or may not go by the monicka Arturios, may or may not be associated in any way possible with moi.  :lipsrsealed

What I can confirm is that I, like the Mystery Wasp Enthusiast, will really like to put one of these bad boys together. that is all I can say at present...

Of course, glad that';s sorted out then, I hate ambiguity & his twin brother annuity, no actually, he';s ok!

Don';t get me mixed up with Sepp Blatter.

And I hate ambiguity myself, although I too like his twin brother ::)

Hi Andy, have you left out the bottom plate of your final draft.
Looking good, I can';t find any 3mm Delrin, plenty of 6 mm.

Rich, it';s here!



No mod';s, seems to do what it should! 

As for Delrin, I use these guys (Trent Plastics) http://www.ebay.co.uk/itm/161315078656?_trksid=p2057872.m2749.l2649&var=460345298161&ssPageName=STRK%3AMEBIDX%3AIT , they sell all thicknesses, but only the thicker stuff 6mm+ in black.  Free postage is a bonus.

I';m using 4mm for integral base plate (above) and 2mm for the rest, it';s plenty strong enough, and not unduly weighty, but that is the art is it not, to get the minimum thickness that will withstand the knocks and rigours, or ';scantling'; as I think it';s known as in shipbuilding terms?

N.B I';m sure the bottom plate could be 3mm, but as it is now integral with the arms, I feel would be a tad too flexible.

[richardg6paj]

Hi Andy,
Thanks for the ebay link, I have come across Trent Plastics before, in fact they are only 10 miles from where I live. What threw me was that I am looking for Homopolymer acetal which supposedly is genuine Delrin. They seem to be advertising it as Delrin copolymer which doesn';t seem to be correct. Apparently the Homopolymer is supposed to be stiffer than the copolymer, how much stiffer I don';t know! I think we had this discussion before when I suggested trying Delrin instead of G10. Since then I haven';t been able to find any Homopolymer in less than 6mm sheets. So guess will have to try copolymer for my project. Good to see that "your" laser cutter is able to cut it. We need some crash tests now

Lol!  yep, crash tests are next.  I do recall the conversation, and I too struggled to find a supply of homopolymer sheet of the correct thickness, so I';ve been using the copolymer instead.  As you say, POM-H as it is known, exhibits a higher degree of mechanical strength, which would be ideal for this application, but, alas remains elusive.
However, I';m quite pleased at the results I have using the POM-C.    

[flybywire]

Eee up, i';nt geometry great?!

I';m close to cutting my latest Wasp incarnation plates now (although RM insist on keeping me in suspense!) but, on the old design top plate, and to a lesser degree the new v, if the FC is mounted as I have it, i.e 5mm below the plate, protected from the side and bottom, the top is slightly exposed to wet stuff, which could be a fun spoiler, so, I was designing a simple clear (coloured if I can get it  ) 1mm perspex cover.

In the process of applying a contour, the drawing started to look like this:




Lol!  I know it looks stupidly complex for a simply cover, but it';s just given me a monster idea of how to incorporate a layered case as part of the frame.  It would accept any standard size 32 bit FC, but obviously pin out';s differ across the platforms, so maybe a bit tricky to have a one size fits all solution.

Deep breath, back to the drawing board!

[atomiclama]

Well you have convinced me on this Delrin stuff and seeing as though I need to by some material, I';ve used up my supply of ply, I might as well give this ago.

What thickness do you recon for main plate? I';ll be using some carbon arms from a previous project and just need to make a main plate + clean battery / fpv plate.

[annikk.exe]

This site sells the stuff, I think?

http://www.plasticstockist.com/Delrin-Sheet/Natural-Delrin-Plate.aspx

[atomiclama]

Yeah found that , but there is a link further back in the thread that does it cheaper and free P&P I think

[flybywire]

THickness?  Have you got the schematic/sketch of the quad?  Generally speaking, 2mm is fine for plates that are bolted together, as with 10mm spacers etc, as it provides rigidity.  As you see, I';ve used 4mm for my main plate, but that';s because it';s integral with the arms, so needs to be mega strong, which it is, but huge overkill for normal plates, I think!  Still a drawing would be useful to better advise.   

N.B  Sooo...Maybe as a general guide:

Arms and integral arms/body =4mm
Motor mounts like I made for my 350 = 3mm
general plates/legs etc without direct motor stress =2mm

Trent plastics are fine, free postage, but allow a week for the ';free postage';!

Oh, sorry.. I didn';t realise...

I saw this:

I too struggled to find a supply of homopolymer sheet of the correct thickness, so I';ve been using the copolymer instead.

...and thought maybe I could help.

That site says they can do any thickness you want right down to 0.5mm, you';d just need to contact them with your requirements..

[H_Simpson]

Any more progress?
