In my quest towards getting better efficiency and more performance and flighttime out of my power systems , I decided to build a “Thrust stand”.

This is a great tool for comparing different props, motors, batteries, ESC’s separately but also as complete power systems.

The beginning of this episode is a time-laps build of the FunJet. I think it turned out pretty cool. After that follows the maiden flight, which went great without any crashes.

Since the old modification caused me to loose a plane, I decided to get myself an original antenna and put things back to normal. Today the antenna arrived and after a little time of tinkering it was in place. Now I can start flying again.

These are the two airplanes I bought, the FunJet and the MiniMag with floats! One fast and one slow, one aerobatic and one gentle. I think this they both will contribute greatly to my growing fleet of airplanes. I will start of building the FunJet first and it will happen soon. Stay tuned!

The headtracker that I’m reviewing for FPV-Community isn’t working as it should. The headtracker only registers movement in one direction on the x axis. When I tilt the headtracker forwards, the servo moves forward, but when I tilt the headtracker backwards the servo doesn’t move at all. After several hours of testing I decided to take the headtracker apart and take a look inside of it, to see if I could find the culprit of this dilemma. This is what I found:

On one of the accelerometers a capacitor was broken. This must have happened during construction of the headtracker since the PCB was very well protected inside of the device. I've e-mailed AEORC and asked them for the value of the capacitor, hopfully exchanging the capacitor is all that is needed to make it work again...
So for now the testing is at a halt.

After being sold out here in Sweden for quite a while, I finally got my hands on RCadvisor’s two books called “Model Airplane Design Made easy” and “ModiFly”.
The first book is about general model airplane design, covering things like aerodynamics, aviation design history, power systems and more. The other book is about a specific design made by Carlos himself that cost less than 5$ and takes less than a day to build, it explains all decisions made and journey to the finial design. If the books are any where near as good as RCadvisor’s calculator they will a treat to read. I’ll report back to you all what I think of them as soon as I’m finished reading.

A couple of weeks ago I got my hands on a GU-365 3-axis flybarless stabilizer. I been wanting to build a tricopter for quite a while but the cost have kept me from taking the plunge, but now that I’ve got a 3-axis stabilizer that might work, the cost would drop enough for me to justify buying the rest of the parts.

But I didn’t want to chance that the GU-365 might work so I asked a friend in Denmark that have loads of tricopters to try it out for me.
Unfortunately the results of the testing were not what I had hoped.

- “It was out of control like nothing else I've ever flown, and it was FAST, I gave up counting the rolls as I gave everything I had in pilot skills to get it down in one piece...”

This means no tricopter for David, at least not for now...
Hmmm, might put it on a plane...

This episode is a tribute to the death of my Multiplex Blizzard.

Ever since the Assan modification of my Futaba 7C I’ve wanted to be able to use the same antenna on both transmitter modules. And now, finally, I got my hands on a U.FL to SMA pigtail. Here is the result:

Looks nice doesn’t it?

In this episode I cover some of the basics in LiPo batteries, like cell-configurations, mAh, C-ratings, the 80% rule, balancing and among others.

In the end of the episode I overcharge a LiPo until it explodes to show what can happen if you leave the charging unattended, here are some pictures of the inferno:

It’s the XGY-1000 from AEORC.com and it’s going to be my first official review for FPV-Community.com. It looks quite nice and I hope to be able to try it out soon.

I just finished up a guide on how to get 180° of servo travel. In the guide I address 3 different ways of getting more servo travel. I also give a complete guide to modifying a servo DIY style, using only two resistors.

I’ve wanted to get my hands on a GU-365 3 axis flybarless stabilizer for a while, to do some experimenting with. Well I had some luck, a guy wanted to trade one, so I made him an offer. It arrived in good condition:

I have only had the time to do a few experiments but so far it seems to work as expected. It has no trouble arming ESC’s which is nice, since I’m having thoughts about building myself a tricopter. A friend of mine in Denmark that has a lot of tricopters offered to try the GU-365 out for me on one of his machines, so the GU-365 is on it’s way to Denmark.

Since I’m a curious person, I took the GU-365 apart to see what was inside. Click on the “Read More” to see the pictures. Read More...
