About Video Transmitter

I know that most countries have legislation in terms of radio / video transmitters. I also know that many people do not always comply with this legislation.

What are your experiences and opinions with video transmitters?

1. Frequency

2. Power

3. Range

4. Range with Antenna tracker.

5. Effect on GPS signal.

6. LAW

I know that there is no reason to discuss range since the law says in line of sight when… Continue

How to get more room for payload in Easystar.

I made a new fuselage for the easystar to get more room for payload. This proto is made in 2 layers of carbonfiber. The carbonfiber is very easy to work with, so if any one out there like to make some modifications just go for it.

I got the carbonfiber from here

The weight of the T-REX fuselage is about 140g = 4.93 ounces - still need to make the inner fuselage so the… Continue

I have a proposal for a new platform for uav.

I know this is a bit risky to propose a new platform for a UAV, but I think it could be a very good platform.

The system are slow, stabel, won't brake if a crash should happen, easy to operate, ok payload.

How about having ArduPilot installed on a RC Paraglider.

I hope you all can se the opportunities with this kind of systems.

See more here RC… Continue

Reply from Multiplex on a request for a bigger "easystar" model.

Here is the answer from multiplex on a request for a bigger model like Easystar.


we got similar requests from several other pilots as well.

First of all, the Easy-Glider was made in some view to get a bigger plane with adequate flying caracteristics than EasyStar.

We know, that with the prop in front it is not that easy to convert, but some people did this with good success.

On the other hand it is not possible to make the same model simply…

Pan and tilt for video link

Because of bad weather her in Denmark I had the time to make a pan and tilt system for my Seagull 2200 inspired by the pan and tilt system from Range video. (DIY is much cheaper). I have ordered a 1 Watt 2,4 Ghz Video TX and RX from Range video so now the Seagull will soon be ready for a FPV flying.

Still wayting for better weather before I can start testing Ardupilot… Continue

First testflight UAV Seagull 2200

Yes the first testflight is over, and the seagull 2200 are still alive.

I planed a small 5 waypoint route on a open area near Aalborg, Denmark.

After calibration on the FMA sensor I was ready to give it a try.

After a little manual flight I pushed the auto button on my remote CH 5.. So far so good. The plane started making bit of rocking with the rudder - after a sec or two the plane gets stabel and just holding… Continue

UAV Seagull 2200

Now my Seagull 2200 are ready for first testflight. I have uploaded the ArduPilot_EasyStar_WP code on the board so I "hope" it can make a testflight so I can optimize here and there...

The seagull 2200 is a very stabel mashine modified with a stronger motor and a bigger prob.

Offcause I… Continue
