Put 4 batteries through the Tri yesterday.. spent all of them battling the wind

Still need to tune this KK though, it tends to wobble like hell on full power!

Due to all the wind the tail "rotor" servo has come loose. Luckily i was only a few metres off the ground and on the last battery! Wouldn't have been anything catastrophic though. I'm putting this down to the sheer amount of hard work the tail had to do battling the wind!

Terrible jelo effect from the GoPro footage too

To do:
Fix the tail servo down securely.
Get my head around KK tuning
Eliminate the video wobble

:confused:

Nice

yeh it has been a bit windy! Good to see it up in the air though

That looks like a good place to fly

Video wobble I find rubber mounts on a platform and some spongy foam type stuff gets most of it out. Although I have a Möbius not a go pro

It's a great place to fly (soft landings for fixed wing and quads and the like if things go wrong!) but it needs to be a calm day do be really any use.

Quite gusty up there yesterday!

Same principle I suppose whatever the device.. I'll have to have a look what I have, got plenty of foam but the only rubber I have is inner tubes! Hmm...

Is this on top of caerphilly mountain or something ? Anything that will absorb really.

My 250 has rubber feet type mounts which sit under the camera platform, then in use spongy foam under the mobius

Not flown it yet tho.

bwahahaah, well deserved

As far as I can see he managed to pull the Inspire out of air while manually moving camera and props hit him on way down

{SAS}TB · 1 Jun 2015 at 06:54

Ouch !

d_brennen · 1 Jun 2015 at 13:06

Hope the Inspire was ok. Looked like it had a nasty accident

On 12" props and 4s you will probably want something around 600-700kv.

Armatten Morphite built. I've tried to keep it as tidy as possible. It's missing the receiver at the moment as D4R-IIs were on backorder. It shipped today though.

So, full specs:

Armatten Morphite 180mm carbon frame
Favourite Quattro 4 x 6A ESC with blheli firmware
DYS BE1305 3100kV motors
4x4.5 props
Naze32 FC
D4R-II rx
Micro FPV vTx
950mAh 3S Nano-tech battery

It weighs in at 282g with battery

Pics:

Next to my Diatone 250 for scale

DJMK4 · 1 Jun 2015 at 20:34

Looking cool

bet they fly brilliant!

I wouldn't leave the antenna and vtx like that though. That's got broken vtx written all over it

Won't take a lot to snap that rp-sma connector

Did you solder the escs to motors?

Rilot · 1 Jun 2015 at 20:35

Yeah, I don't like it. What do you suggest I do with it? Maybe get a little whip antenna for it?

DJMK4 · 1 Jun 2015 at 20:39

Its hard to judge how much room you have

Iv bought a 5cm pigtail with bulkhead for my 250 setup.

Does that vtx fit inside the frame ? Would you getaway with a small pigtail ?

Rilot · 1 Jun 2015 at 20:44

I could move the vTx inside. I'll see about a pigtail, thanks.

DJMK4 · 1 Jun 2015 at 20:53

I ordered mine yesterday from banggood for £2ish free delivery although ships from China. Don't mind waiting a bit longer.

http://www.banggood.com/5cm-RP-SMA-Male-to-RP-SMA-Female-Right-Angle-Cable-p-956188.html

Most UK stock get the from China, but a lot of them are longer or more expensive , great for 250 but not sure what it would be like on the smaller one

If not try and mount it somewhere where the vtx is out the way a bit and you can strap the antenna in place so if you have a knock the antenna takes the force not the vtx connector

man I'm on a bad luck streak... Quad is super well tuned, flying perfectly on 4s & gemfans 5x45 with the SunnySkys, doing 3x rolls with very little loss in altitude, front and backflips no problems.. but...

I've got power loss issues, convinced it's the crappy orange Rx that I had to trim the antenna after it broke. Crash took a brand new spironet, luckyly this time the pigtail saved the VTx but the antenna vanished and the mobius seems up the ghost too... (my second one...) GRRRRRRRRRRR. To add insult to injury they removed all the goal posts from the field I was flying at so now I have a massive but empty field....
