Bring me light

februari 23rd, 2012 | Posted by admin in Uncategorized - (1 Comments)

We got all four seasons here in Sweden. Right now we’re in the dark and cold period of winter and even though it is a lot brighter than it was during the darkest time of the year it is still not bright enough to fly after work. This isn’t just bad since you’ll get a lot of time to upgrade and rebuild your models. I’ve spent the last couple of weeks to make a lot of modifications to my Multiplex Easystar. My goal was to create a plane that could be used in any type of conditions and also a plane that I didn’t have to be so afraid to use. Therefore I decided to make it lighter and cheaper. Since I already got a bigger model that is able to carry more weight I decided to just use a RMRC-540 camera instead of the Gopro Hero HD that I used to fly with before. I’ll make all high quality videos with my Skywalker or Tricopter and just fly cause it’s fun with my easystar.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This is what the plane looks like without wings. Let’s take a closer look below.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

A lot of things have happened here. I did buy ReadyMadeRC Easystar pod with pan/tilt but since I wanted to keep it easy and light weight I decided to just go for the pan axis. I modified the original pan/tilt pod and routed a hole for the servo. Then I used CA-glue to attach the servo to the pod. The servo is equipped with a SSV4 servo stretcher that allows the servo to move up to aprox 170 degrees.

The camera is the same that I’ve used for a while RMRC-540. It’s really a high quailty camera but I decided to try out a new low light lens. Have a look on its size – it’s huge! I haven’t tried it in air yet but after a couple of tests in the backyard I can tell that it makes a lot of difference and I definitely think that it’ll make night navigation a lot easier.
If you look closely you can see three of the seven LED’s that I’ve mounted on the plane. The green one is located between the rudder servo and the pod and the other two (both white) are located on each side of the ESC.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

A closer look of how I mounted the pan servo to the pod.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This were the place where I hid the lipo that powered up the camera and the transmitter. RMRC’s Easystar pod has a compartment at the rear for that battery. The 3S 500 mAh Turnigy lipo battery has almost the same size as the Immersion RC EZOSD that I’ll use which were great news for me. By mounting the EZOSD like this I can always reach the buttons and cables on the other side. Right under it is another LED.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The RC receiver is hidden inside of the body.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The EZOSD got a lot of problems acquiring satellites since the gps antenna was hidden under the motor and esc and in between a huge amount of cables. Quite soon I found out that it worked better if I moved the EZOSD a bit out of the body but the problems continued. I did take a look in my huge RC box and find the long EZOSD GPS Antenna cable that was supplied included in the EZOSD box. The modification is very simple to make. Just cut the EZOSD’s shrink wrap open and carefully take out the gps antenna. The EZOSD is basically just two parts (the OSD-unit and the antenna so it’s no risk that you take out the wrong part). Loosen the gps antenna cable from both the OSD and gps antenna (a good advice is to take a picture of how cable were connected before you take it out) and replace it with the new longer cable. Take it out in the direction you want to and add a new shrink wrap to the OSD. The next part is to add shrink wrap to the gps antenna and connect the cable to it – it’s as simple as that.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

It’s not easy taking a picture of how the LED’s look like when it’s dark outside. I can tell you that it looks a lot cooler and better in reality. The LED-kit that I bought contained a total of 8 LED’s but I did just use 7 of them since I managed to break one of them when I did try to install it. There are four different types of LED’s in this kit:
- Always-bright (red, green and white)
- Strobe (white)
- Slow-flash (red)

I’m really looking forward to try these mods out. Feel free to contact me if you got any questions regarding these modifications or other RC/FPV questions.

Review: Phoenix RC Flight Simulator V3

februari 16th, 2012 | Posted by admin in Reviews - (0 Comments)

If you’re only into FPV-flying a simulator might not be needed, especially if you’re ”just” cruising around in a forgiving Easystar. But if you’re like me, a total newbie to 3D then you might have to rethink this … An RC simulator is good in a lot of ways:
- Will give you a lot more hours of practice each year.
- You’ll save a lot of money thanks to less crash damage. (Especially if you’re a helicopter pilot).
- The RC simulator will work in any type of weather.

There are a lot of different RC flight simulators out on the market. Some of them are crap, a bunch of them are good and a few is brilliant.
Prices are between 150 SEK ($22) for the cheapest to 2000 SEK ($297) for the most expensive ones. A rule of thumb is that the ones mentioned last will have better graphics and be more realistic.

I decided to buy the Phoenix RC Flight Simulator V3 that is in the upper priced segment (1195 SEK, $178) due to several reasons. I like the latest technology and I wanted it to be as realistic as possible since my new (and loved) Sbach behaves like a person sitting on a unicycle for the first time in comparision to my Skywalker or Easystar. The package doesn’t include a dummy transmitter (as some other simulator does) and this is perfect for me since I already got my Futaba 7C.

The box contains the dvd disc, a starting guide and a cable to connect an Arttech/Graupner/JR-transmitter to the computer. Several adapters are available (Futaba FFP, Futaba (round) Hitec DIN, Multiplex and Sanwa RD + RDS. I bought the Futaba FFP and the fit of the adapter is perfect so there is no risk of a loose connection between those two.

The Phoenix is basically just plug-and-play but the first time you start it up you need to do a minimal setup your transmitter (and controls). The interface of the simulator is great so you don’t have to use a manual to get a grip of it. Every time you start up the simulator it will search for updates and install them. This means that you’ll always have the latest version. Best of all is that all updates are free (most other simulators take a fee for those). You can change and setup almost anything the way you like (weather, wind, time of day, failures etc.). There are also several training and competition modes so it’s definitely a simulator to grow with. Each month a couple of new models are added and they are of course free too.

I think the Pheonix RC Flight Simulator V3 is one of the best choices (for those of you who already own a transmitter). I really like it and it feels really realistic and the graphics are amazing. I practiced flying inverted in the simulator an hour or so and was able to do the same in a relaxed way with my Sbach outside – so it really works!

Today was a perfect rc flying day. I decided to take the oppertunity to try my Sbach outside. The sun was shining and the temperature was around -5 degrees celsius. I flew three batteries before my fingers got cold and everything went really good. The plane behaved really nice in the calm wind and it was just awesome to not being limited by the ceiling and walls of the football field that I flew in last time.

The fleet is expanding

Review: Immersion RC EZOSD

december 4th, 2011 | Posted by admin in Reviews - (0 Comments)

I would say that an OSD (On Screen Display) is the best upgrade for your FPV-system. The OSD will take your flight to a completely new level, it makes them both more fun and safer.
There are a lot of brands and models to choose between. Even though there are a lot of cheap OSD’s I think the best ones cost between $125-250. The cheap ones are very limited since they can only show basic things such as battery voltage level while the more expensive ones will give you all the information needed for having a really good flight.

When I was about to buy my first OSD I checked out a lot of OSD-videos on youtube and I really liked the interface of the EZOSD. It looked very clean, got ”all of the essentials but none of the complexity” as it’s said, and it’s supposed to be really easy to install. One more reason I bought this clean OSD was that I thought that all the information showed on the screen were going to be recorded on my gopro’s memory card. I think the best FPV-videos are the ones in HD without all text and information from the OSD and I was scared that the information would distract the video. But I was wrong about this. The information from the OSD can just be recorded from the ground station only.

The EZOSD is basically just two parts (an OSD with three buttons and a 100A current sensor) plus a couple of cables. The current sensor has integrated connectors (deans). The installation is as easy as it’s said to be and it should look like this when you’re done (I’ve borrowed the picture from the EZOSD’s manual).

The system will work when you are done with the wiring above.

It may take <5 minutes for the GPS to find its position. The OSD will indicate that it’s searching for satellites with 9 small dots on the upper right corner of the screen and when that’s done they will disappear and now you’re almost ready for your first flight with the EZOSD. But on the first time using your EZOSD you’ll have to make a couple of basic settings. Those are all made directly with the OSD (no need to connect it to a computer). Push the mid button (MENU) to make the adjustments with the UP and DOWN buttons.

I think the menu is very easy to use. The max altitude and max distance are two very good features. You’ll notice that it’s very easy to get to far away or to high up when your flying. By choosing your limits before your flight the OSD will tell you to descend or turn back home by flashing rapidly with the altimeter or the distance (ground) to pilot. The last one sets your home position, exit the menu and go flying:)

The interface is splendid and you’ll feel like you have full control over your model from the start. The picture below shows what you will see on your screen.

All the information on the screen are shadowed which means perfect visibilty both against a bright sky and a dark ground. As soon as your model has touched down and stopped the EZOSD will turn into a Flight Summary mode and there you’ll get all the information from the flight.

Other features with the EZOSD:
I think the coolest feature with the EZOSD is the ability to connect it to your iPhone or iPad to either get live telemetry or to see your plane and your ”home” on a map. This is great if you land on a huge field with high grass or if end up in a forest. Hopefully you’ll be able to find your plane really fast thanks to this feature. You can also add an antenna tracker to make your antenna aim to your planes direction.

The EZOSD is meant to be easy to use and I think it might be one of the best basic OSD’s out there. But, it has its limitations and miss one feature that I think is really good to have and that is return to home (RTH). You can’t compare this OSD with other more advanced OSD’s since this one is made to be basic but I do think it’s very important for you to find out if you want a basic OSD with a clean interface or a more advanced OSD with a cluttered display where you will get all the information needed and even more.

FPVStockholm: 4/5

New video! Elfvik FPV meeting

elfvikfpvmeeting

As an FPV-pilot I’m used to get up early in the morning, take my plane and the rest of the equipment out and drive to a place where I can sit by myself. I’ve always thought it would be so much fun to fly with other FPV-pilots but they’re not that easy to find… This day I was invited to Lidingö (Elfvik mfk) to fly with two other pilots.

We met up late in the morning and rigged all the things up, looked at eachothers planes and ground stations. It’s so much fun to see how other pilots have solved problems and I got a lot of tips/hints during the day. We were lucky with the weather since it was sunny and warm but it was quite windy and the winds increased the longer the day passed. So we were just able to fly two lipos each. The rest of the time we spent talking and laughing:)

Björn made a sightseeing for us two since we were unfamiliar with the area so we could just sit down, relax and get to fly with his easystar thanks to the video splitter. Second flight (first for me) I flew by my self to get familiar with Elfvik and on the third flight me and Björn flew together at the same time. This was a completely new experience for both of us and it was so much fun! We found out pretty soon that the sky is HUGE since it was really difficult to find each other. But at one point I saw his easystar only a couple of meters away. If I had travelled a bit faster we would probably have hit eachother in mid air:)
The air-to-air flight starts from 01:51.

Hope you enjoy the video.
