Built a new more robust landing gear for my AP/AV Hexacopter. Due to the movable leg holders a wide range of landing gear width is adjustable.

After balancing six new APC 10 x 4.7 Slowfly props I've retired the EPP 1045 props. The APCs are much more sturdy as the EPPs specially important when the TOW of the multikopter is a bit higher.

Just started to build a new FPV plane beside of my good ol' MPX Easystar. It's a Skywalker from

http://www.bevrc.com/skywalker-168cm...igne-p-17.html

a plane specially designed for FPV with a huge payload room. Below the parts for the power plant, a TLRS UHF Long Range Receiver ( http://www.webx.dk/rc/uhf-link3/uhf-link3.htm ) and the servos. For automatic RTL (Return To Launch) I'll install an autopilot from Feyutech www.feiyudz.cn (see pic below).

Just converted also my T-Rex 600CF to FBL (flybarless) with the Align FBL conversion kit, consisting of the FBL head with swash plate and a 3G FBL-stabilizer. First testflights was a success at all. R/C link is Thomas Scherrer's UHF Long Range System TLRS ( http://www.webx.dk/rc/uhf-link3/uhf-link3.htm ).

Converted my T-Rex 450SE to four blades with a CopterX 4-blade rotorhead, a set of Spinblades (www.spinblades.com) and an Align 3G flybarless stabilizer. Testflights was very successful, so I started to integrate the little T-Rex in an Align scale fuselage (Eurocopter EC-135). Last missing part at the moment is the scale fenestron (see pic below) so I've to wait a little bit with this project. Btw. T-Rex 450SE is also equipped with Thomas Scherrer's awesome UHF Long Range System TLRS ( http://www.webx.dk/rc/uhf-link3/uhf-link3.htm ).

Managed a successfully maiden of my new MPX Funjet (the 3. Funjet already ), this time finally with Thomas Scherrer's awesome UHF Longrange R/C system TLRS ( http://www.webx.dk/rc/uhf-link3/uhf-link3.htm ). Lost before two Funjets already due to interference on the 35 Mhz R/C band. As on each flight with each of my models the awesome Junsi CellLog 8S LiPo logger was also on board.

Just got new batts for the Hexacopter, two 2S 6000 mAh nano-tech LiPos from HK, up to unbelievable 30 A charge current (5C) and 300 A discharge current (50C) ! Will connect both then to a very flat 4S 6000 batt.
