hi all, well, it's been a while i must admit, but here i am, back once more

wanted to take the plunge for some time now, and finally got my first tricopter kit, it's the mini version from dave at blueskyrc.com.

the kit itself is very well cut from ply, all fits nicely, with only some minor sanding of some components. with so many chinese kits needing masive work to fit together properly, this is amazing! other kits i have had from dialfonzo have been great as well, so the qc in usa and canada far excells those from the far east!

heres some pics, i shall continue later..........

well. what more can i say.......

out one afternoon, got it set up perfect, several flights beforehand, no issues. everything goes ok, flying good, then, for no reason, shoots off and forwards like a bat-out-of-hell and dissappears!!!!!!! no response from any tx commands!!!!!!

now, after a fair trek up the downs area where i was, no sign of it, anywhere. thought it was lost for good....... a few days pass, and a friend calls to say that his father owns some land near some wind-turbines, and was walking his dog when he found something odd, some rc gadget????
he brings it down, and guess what? flydumini! except, mangled! well and truly! said his dad found it around 100ft away from one of the turbines, mashed to hell, but all there.
sadly, my camera is playing up, but as soon as i get it sorted i shall show pic. only salvageable part i can see is the prop adapters!

funny thing is, the turbines are about 3 miles from where i fly on good calm days! and if thats bad, to be roughly abused (i assume) by a turbine blade? mad.

if one of those blades break.... dont blame me....... or flydumini......

Here's a little update of the progress so far......

The motors (hk 2000kv's) have been bolted on, using m2.5 x 6mm stainless bolts, the esc's are turnigy plush 6a. These have been programmed with card and throttle calibrated before soldering onto flydumini.

The BMA020 should be with me tomorrow now, so that will be fitted, as well as led's soldered, but those will be at a later date. Ordered an ftdi cable/bob so will have to wait for that to arrive before i can upload the sketch to the arduino pro mini.

I decided to use a fc protection plate made out of carbon for the flydumini. This plate was originally made for the mini quad i made, but decided on a dome instead, so it's now found a new home

Using gws 3 blade props, as had these already, just need to balance them.

Update;
Still waiting for BMA020 to arrive, so added my 6ch orange rx (minus case, as done with wraith project), i estimated total weight minus lipo to be 148-150 grams, suprised to find only 140g so far!!!! Happy with that!

This is for my flydumini frame/fc build........

Quality is excellent, and nice and light, considering it's 2.6mm thickness! So far i have soldered the pins and the arduino pro mini, which i also got from flyduino.com (thanks to paul bake).
Wii motion plus going to be used on this, along with the following.....

Turnigy plush esc's (either 6a or 10a, undecided as yet)
Hk 2000kv 10g motors or c10's
BMA020
Orange rx
5x3 3 blade or 2 blade props

Build log updated regularly........

Wii motion plus now soldered and fitted to the flydumini, starting to get there slowly, lol.
I used sellotape outdoor foam sticky tabs to affix wmp to the frame. The advantages are twofold. Firstly, they are very sticky, so no fear of gyro coming loose! Secondly, the foam they are made from is very good at absorbing vibrations, used many times on my multi's and heli's, wont use anything else now for affixing gyro's or securing servo's ...Continue Reading

Received my fc board from luis at myrcbuild.com today!

The finish is excellent! Nice in red, supplied with llc, ready for 3.3v. Build progress will be updated as and when progress happens, so stay tuned!

Progress report; Soldered most pins on now, as well as llc!

Here's the plan......
wraith is currently using kk board, y4/6 is on hold, and i'm having ideas. Noticed there is a significant amount of threads with people needing help with kk/hk boards, and few (but VERY informative) multiwii threads!
I'm drawing to the conclusion that while kk is good to begin with, like anything, it has limits. The same i guess can be said about multiwii, however, multiwii is FAR more adjustable, and with added bonus of upgradeable (ie; baro, mag, auto-level) features!

While minsoo's flycam and gps boards look great, my limit is . Far too expensive for a cleaner on a basic wage.
Kk board is good, but limited in features.

And then we get to multiwii......

paris boards, warthox boards, bluesky boards, miniwii boards, dialfonzo boards, to name but a few, the choice is vast! also the prices are favourable, and you can upgrade as you go along.
Adjustability is also very good, gui looks reasonably simple to use!
size, depending on board, varies, but that's simple enough, choose the right one for your own needs.

So, miniwii and dialfonzo boards for me, wait for availability, buy, then rewire my brain
Sticky: wraith

mostly finished the makeover of the wraith. total weight without lipo is now 196g, instead of 207g, saved 11g. whilst not a lot, every little lost helps! added a new vac formed dome, in gloss black, fixed with small velcro tabs to frame plate. i do prefer the matt though, as used on my y4/6, so may change that later. i have also added led strips to the arms for night flights!

also used 6"gws 3 blade props now, as seems to be slightly more stable, and motors barely get warm even after a good run!

also tried 3s lipo, and boy does it go! really lights up well too! motors and esc do get warm, but nothing drastic. i shall use 3s for night flights (also cooler at night, helps keep temp of motors and esc's down), and 2s for normal daytime running.

needs cable ties and a small receiver plate made up for front, good rx reception, and i like the "bug" look it gives

Rebuilt Wraith Quadcopter Test + Led's! (1 min 19 sec)


Edit; Now managed to glean another 4 grams off the weight by using one full servo lead, and signal only wires for the rest! (board to rx connections!) so total is 192g without lipo now!

got in from work,

food, chill, then decided to re-do wraith mini-quad........

3:44am, soldering, while listening to new evanescence album, things going well, new dome sorted, 6 grams lighter than previous one, led strip on each arm, runs very bright on 2 cell!
ditched landing legs, as now relatively proficient at flying now, plus saves weight. gonna try 6" props, as weight reduced, so less stress on motors, possibly help stability?

new pics posted soon

well, all been put together, looks very sweet! using it as a y4 at the moment, although when other motors and esc's arrive, shall give it the y6 treatment. i made a nose for it out of some scrap 1mm carbon sheet offcuts i had lurking around, to mount the rx and keep things tidy. the ariels look like bug antenna's, so have nicknamed it the "weevil", lol.

also fitted some led strips to it, which are impressive considering they are meant to be run on 12v yet are still bright on 2 cell lipo!...Continue Reading

received my new frame today from myrcbuild.com (thanks louis and eric!), so done a loose build to see what she looks like.......

some light sanding of parts for a good fit, build quality is VERY good, looks good, goes together very easily and quickly. more to follow........

ordered some motors and esc's for new build.....
lol.....mwah ha ha ha haaaaa! (really bad attempt at evil laugh!)

flying on windy day = quad meets tree + speed = broken props....... grrrrr!
never mind, new ones coming......lol

In between rain showers, managed to get a few minutes flying time. wanted to see how the little thing would cope in gusty wind conditions, and also probably the only chance i'll get before we get hit by the really high winds as a result of hurricane katia.

It got really blown about, and also decided to increase the gains slightly.....

Christmas comes but once a year........
but what do you do with those cheap battery powered led christmas lights afterwards?

Answer: butcher them for your multirotor! Enjoy!

well, it's finished, and flies pretty well. still a bit wobbly, but that's me as a noob, but slowly getting steadier as more flights are logged!

there has been some alterations, namely the arms, as i found the 15mm was causing me to obtain not so good lift, so dropped to 10mm, and all the better for it! also a slight re-design of the landing gear, which was re-designed as was bending the bolts inwards/

overall, i'm pretty happy with it, and would not have been possible without.....
inspiration (tretch5000), ultra talented,
soldering of damaged board (mike barton) firmware and all round saint,
kapteinkuk for making these boards and supplying firmwares,
matt halton for encouragement,

and all the helpfull people on the forums of rcgroups!

components are.....

4x turnigy plush 6a esc's
4xhk 2000kv 10g brushless motors
kk blackboard
1mm carbon sheet
m2.5 bolts
used glowbracelets
old tv ariel (15mm arms)
10mm alloy box (revised arms)
orange 6ch 2.4ghz rx (without casing)
spektrum dx5e dsmx tx


03092011019 (1 min 54 sec)


the vid was shot indoors, only 3rd flight, was raining hard otherwise would have been outside!

love it.......... soon time for another project i think.....

was really looking forward to flying my first quad build when......

one minute board working great, then disarmed. since then, loaded all firmware i could find, not one worked. it went bonkers! lucky i had disconnected the props or the effing thing would have taken my face off!

tried all fixes, checked esc's, receiver, transmitter, but to no avail.
brought the board from seller in hongkong, looked a his profile, and behold, no longer a seller! mmmh, wonder why that is then, eh!

so, if you are thinking of getting one off ebay, be careful. you may be lucky, or not. i'm not in a financial position to be spending a fortune, but in hindsight it would have been better to buy from official distributors!

so, after this experience, i'm now a sceptic.....

maybe multiwii is way forwards........

anyone selling paris board and arduino with wii gyro and auto level?......
reasonably cheaply?......

UPDATE:

thanks to the incredibly talented mr barton, it seems the problem boils down to naff soldering on the board, namely the atmega 168 pins. this is what was causing the problems, however he did mention that the gyro's are very good indeed.
so it would seem apparent that the main cause on this one was the soldering of components, and something for others to be aware of!

just a few pics to show the 12" frame i designed and built for a friend!

esc's turned up today, so power leads all soldered. new turnigy 6a's are slightly larger, so my idea of tucking them in the arms for a neater look has gone out of the window, lol!
when transmitter arrives, shall set it all up, post more pics, and hopefully video of how well it fly's, (or not)

stay tuned..........
