I have never ever requested things like this. I was every time trying to solve everything by myself, but now I can't do it all alone.

My friend need help of all generous peoples around, therefore I would like to post this request also here.

The link on IndieGOGO campaign is bellow. This has nothing related to RC. All you get back from this contribution is my input to RC community.

Sorry guys, I know this is absolutely off topic.

Thank you all and Happy New Year!

Update 19/01/2015: Unfortunately the campaign until this moment didn't raise any funds, and my friend asked me to close the campaign since a new campaign was started by a local Non-Profit organization.

Well, I have finally come to a conclusion, and here is what I think:

660mm quad with FPVModel MC-3508 700kv motors on 3s. Not intended for acro flight.

Killin'It (3 min 40 sec)

Posted by schumixmd | Dec 13, 2014 @ 01:16 PM | 2,373 Views
Today I have test flown the FatCat quad for first time. I called it FatCat because it is a little bit on heavy side. Take off weight was 1550 with 3s3000mah pack, mobius, and ET eLogger. I had two fresh charged packs with me, and aimed for a 5min flights.

This weren't just hover flights, nor 3d flights, but somewhere in the middle, and everything LOS.

Long story short:
- in both 5 minutes sessions I have consumed around 1400mAh of 3000.
- hover power is averaging 160watts.

Here I am attaching logs from both flights and the predictions from ecalc.ch with T-motor MN3508 so everyone can compare how FPVMoldel motors perform versus T-motor. I would say - they are performing the same but cost different.

After speaking with the seller, I have identified that the blue paste inside the motor is actually balancing material. Which means that these motors comes already well balanced.

Well guys, not that I have reinvented the wheel. I am just proud that after 3 years I have finally built it, my UHF Relay that will allow me to use DragonLink v1 module with my Hitec Aurora 9 or Spektrum DX8 wireless and trouble free.

The most important point is that because DL v1 does not have auxiliary head tracker port I wasn't able to use Fatshark head tracker because Aurora does not support it, but on Dx8 the trainer port was busy with DL module. Now, on the DX8 the trainer port will be free and I will be able to finally use the tracker, of course - after I will get an ppm capable spektrum receiver.

Not much to say! Went out for slope soaring!

Slope and thermal soaring with Phoenix2000. (3 min 35 sec)

Today we went flying around!

No more testing, only enjoying the scenery, but noticing so high thermal activity we did not resist to see if this plane is good to go thermals.

The answer is quite clear - the plane is quite good for thermals, much more if you try to work them out. We didn't put any effort. We just flew around the mark where plane climbed throttle off. Kinda fools, but look how it goes.

Sorry for the bad quality. Still can't get decent quality from EasyCap Someone willing to donate a DVR?

Skywalker Naja Working Thermal (4 min 44 sec)

Posted by schumixmd | May 11, 2014 @ 03:11 PM | 3,161 Views
Today, on a calm day, took the Naja for some short testing.

After the maiden flight I have improved it a little.
  • Installed new motor NTM 3530 1100kv, instead of old Turnigy 3536 1300kv. The propeller remained the same 10x4.7.
  • Relocated the vtx from tail boom to the wing.
  • Relocated the GPS and Rx on the main plywood plate more forward.
  • Removed 90g of ballast which was needed to obtain the CG at 80mm from LE.
  • And some more ground tuning of MyFlyDream Autopilot. The Autopilot also got version 1.4 firmware.

Voila! Now the CG is at the same spot but the plane is 100g light.

The plane got many modifications so I was a little worried how it will go, 'cause I was alone, and had to hand lunch it by myself, which I never did with this plane.

I engaged LAUNCH mode on MFD AP, got full throttle and launched it. The plane climbed smoothly with only little left banking (1-2 degree).
- Amazing! I flew over 20 minutes with a 3s 5000mAh tuning the AP. I wasn't afraid anymore to hand lunch it after every landing, 'cause launch mode worked like a charm.

With a single battery I have done all the testing and tuning I was hopping for, but still got a lot of time until full sunset. So I decided to go for an endurance flight.

Loaded 3s2p 3000mah (6000mah total) and took off.

Unfortunately I still have not invested in a DVR since I am in hobby. Every time more important things got in front. Also the MFD AP doesn't log the flight. So I don't have any proof of my flight...Continue Reading

Hello guys,
Some time ago, I was given the chance to review a new plane on the FPV scene. The plane comes from the well know Skywalker company. Considering the reputation of their previous plane which is in service for most FPV pilots, the expectation for the new plane are, let say – high enough.
Ladies and Gentlemen – Skywalker Naja is the plane I am going to review.

Description:

Here I have the chance to say Thank you! to FPVModel.com store, which kindly provided the plane for review and a big personal Thanks to Jason, who had the patience to work out the delivery method, since the delivery carrier asked a very high price to deliver the box to my country and I had to find an alternative way.
The plane was sent to Italy then forwarded to me by bus.
Upon receiving I didn’t wait too much, and opened the box right away. All foam parts in the box were intact and in very good shape, they even perfectly aligned straight out of the box, thanks to the pre-molded alignment points.

The list of parts in the box:
  • Wings, as you can imagine, they were two.
  • Main fuselage, as you might suppose, two halves of it.
  • Carbon tail rod with very long servo extensions, and some plastic assembly parts installed.
  • Carbon spar which hold the wings on the fuselage.
  • V-tail foam assembly parts.
  • Foam canopy for the lower fuselage bay.
  • Plastic cover for the upper fuselage bay.
  • Plywood plates to be glued inside the fuselage.
  • Plastic motor mount.
  • Packets with 4 pushrods, y-

Since I got the MFD AP unit and till now, I still didn't have any flight with it.
Don't wonder why, it is not because of the AP, I just crashed the plane the AP was supposed to be installed in, because of very aft CG.
- My fault.
But it will fly soon 'cause the damage is very minor.

However, mean time, I was dealing with the AP on a single problem it had.
If you already saw the my video with the OSD overview, then you maybe noticed that the OSD shows my battery has 29.58 volts, but I was using a 3S lipo charged to 11.7volts.
After many posts on the MFD AP thread and getting valuable support from community, I have resolved my problem.
For those who have the same problem like me, and their current sensor reports a greater voltage than their pack is due to wrongly placed two resistors on the board.
The resistors are 590 Ohm and 4.42 kOhm, and they are used to divide pack voltage to 3.3v range and goes directly to sensing line, but being exchanged on the board they divide the voltage incorrectly to 10v, and the the sensing line reports incorrect voltage.
The resistors are easy to remove and solder back in the right places.

Looking forward to fly this autopilot a.s.a.p.

Hi,

When I first time started to look on an OSD with or without autopilot, I was wondering how this thing look like .. what do I see on screen, and what configuration option there are.
I didn't find an video showing that, instead I had to watch a bunch of different video that show specific functions.
Now, when I got the MyFlyDream autopilot, I though that maybe someone like me does wonder how the menu looks like and what settings are present.

So here it goes. The video with the OSD menu overview.
MyFlyDream Autopilot OSD Menu overview (5 min 0 sec)

Posted by schumixmd | Jan 31, 2014 @ 03:25 AM | 3,130 Views
Hi there,

Received my Autopilot form FPVModel.com some days ago and started to review it for Russian forum. Since chanyote66 is doing good work on RCGroups, I think there is no need for another video on "what's in box" in English, and so on..
So far, have updated the AP to 1.11, without even knowing what firmware was installed in it. And have connected it on the bench too see how OSD looks like.

Have to say - I am impressed.

The first version of manual does not cover important features Autopilot has, but it is very good start for connecting it and having an overview of how it works, and how to tune in.

The switch'n'stick menu navigation is very intuitive and just after few minutes I got comfortable with that, although some on screen explanation for different options should be done better.

An important feature manual does not cover:
- Saving/Loading settings for different models directly on AP memory, so you don't have to remember the settings if you would like to install it in different planes.
There are some more menu items that are not described in manual which I think are intuitive, and for sure some of us will cover later on reviews.

For the time being, for thus interested, here is the Russian review and What's in box video:

The year is coming to an end, and we all soon will trace the line and make the summary of what we did last year.
From FPV point of view, I have already made that and compiled a video with the Best Moments of 2013. Thanks to DragonLink I have flown with confidence.

Enjoy the video.
