LotusRC has introduced an interesting product for RC enthusiasts in the T580 quadrocopter, as they call it. Using a sophisticated 6 degrees of freedom inertial measurement unit (6DOF IMU) and an integrated barometric pressure sensor for altitude control, the T580 is ahead of the competition with advanced features that are ready to fly out of the box. Many multicopters only use a 3 axis gyro for stability augmentation; a 6DOF IMU adds the 3 axis accelerometers which gives the system more precision, and Lotus RC has also added a barometric pressure sensor which can keep the model at a given altitude. All this, and in a model which is literally “receiver ready” out of the box!

Lotus T580 Quadcopter – Review
Friday, December 16th, 2011HobbyKing EPP FPV
Sunday, May 8th, 2011With more video equipment being made and sold for FPV flying, there has been a huge gap in the market for suitable airframes. While pretty much any aircraft can be set up for FPV with some creativity, airplanes really intended for FPV are far and few between. The EPP FPV is HobbyKing’s effort to provide an airframe to go along with some of the wireless video equipment being sold by them and others. Designed to accommodate enough payload to satisfy any FPV flyer, the EPP FPV wasn’t intended to be fast, aerobatic, or float like a thermal glider; this airplane is all about being smooth and stable and cruising around with video equipment on-board.

Flytron SimpleOSD XL edition
Thursday, August 19th, 2010The Flytron Simple OSD XL from Flytron is the advanced version of the Simple OSD Ultralight Edition. This OSD has a more powerful CPU and offers significantly more features. According to the manufacturer, the Simple OSD XL is the lightest OSD system on the planet except SimpleOSD Ultralight and still offers most features. Even for the Simple OSD XL, the word “Simple” means that information is presented as simple as possible. The important information is clearly displayed, but the fantastic view not blocked with to many symbols. The manufacturer describes this with a succinct sentence: „Flying like a bird without OSD scraps on the screen“.
We received the following parts for review:
- 1x Simple OSD XL
- 1x GPS 10Hz
- 1x Current sensor 50A
- 1x USB program adapter
- 1x small parts like connectors,…
FY-20A RC Stabilization System
Monday, August 9th, 2010There are already various flight stabilization systems for model airplanes on the market. Now, because of their small size, weight and handling, they are more suitable and affordable for FPV. The new FY-20A (basic) and the FY-21AP (with Return Home feature) are excellent examples of such systems. These systems have no sensors outside the model and perform in every weather condition as well as in complete darkness.
The FPV shop www.fpvflying.com has provided us with the basic version, the FY-20A.

Bormatec MAJA UAV
Monday, March 15th, 2010Dear friends of FPV flying,
Here it is, the long awaited, much-desired aircraft which offers enough space for all your equipment and even can take some extra weight. You are free to choose how you lay the cables – without any spaghetti syndrome.
The “Maja” is developed by the German Borjet aeromodels company and is a real workhorse for FPV with a high loading capacity, high-quality flight characteristics and enough room for all your equipment.
We, the FPV-Community, had the honor of testing this aircraft exclusively. On the following pages you are going to find all the results.

Flytron SimpleOSD Ultralight Edition
Friday, November 6th, 2009This is the SimpleOSD Ultralight Edition from Flytron.com. It weighs about 3 grams and is roughly the same size as an SD memory card.

The OSD came nicely packaged in an anti-ESD bag (a sign of a serious manufacturer). The total package size was tiny, which makes the shipping cheap. The OSD does not come with any physical manual, but you are directed to an online manual. The manual is very clear and full of pictures and diagrams, which explains everything in detail.
The PCB is made from a thin glass fiber lamination making this OSD super light weight. I work in the electronics manufacturing business so I couldn’t help admiring the layout design of the tiny PCB. This designer knows his stuff
