CHK Thermik-Star spezial

101” Wingspan Thermal Glider for REFLEX XTR Thermik-StarThat even applies to the pure glider without drive, which is here set to a 500g lower weight. Given 1.5 to 2 m/s 'Thermal current' in Reflex, it's easy toreach thermals from 10 m 'Launch initial altitude'. By the way, the new glidersound is assigned to this model, but the electric powered variant has still theoriginal drive sound without glider noise.For more information in German on my real model see my Web page. InEnglish, there were only the web pages of the manufacturer CHK. Somereports on the model could be found in the Web using search engines, butmost of them were in German.The REFLEX modelsThere are three basic models: „Thermik-Star E“ (with an electric drive withNiCd batteries), „Thermik-Star E new“ (with LiPo and NiMH batteries), and„Thermik-Star G“ (pure glider without drive). They are flown with standardtransmitter settings.The demo flights „Thermik-Star E“ und „Thermik-Star G“ (hit F9 in REFLEX)show the model’s impressive thermalling and slope soaring performance.There are only two minor problems regarding these models. One problem isthe motor run time of the electric model. After the pre-set 6.5 or 15 minutesthe drive is dead in REFLEX, no matter whether you used it or exploited thermals.Therefore you should set the „Engine running time“ in REFLEX (hitF11) to the planned duration of a flight, so you may use the drive for thelanding procedure.The other problem regards the effect of ailerons deflected up as spoilers(spoilerons). Normally in REFLEX, the ailerons can only act like flaps (flaperons)when deflected down. In this case there’s virtually no aileron effect. Inthe 5.05 Version of REFLEX this problem is solved by assigning transmitterchannels to model controls and generating the control deflections usingtransmitter mixers.Now there are the models „Thermik-Star E tx“, „Thermik-Star E new tx“, and„Thermik-Star G tx“ („tx“ for „transmitter“). All these models are equallyprepared for use with transmitter mixers. Ailerons and virtual flaps both have30° maximum deflection, the two V-tail controls 25° in the REFLEX parameters.In REFLEX, under „Control...“ (menu „Model“ or Shift-F7) you’ll find thefollowing assignment, suitable for Multiplex transmitters, but to be adaptedto other transmitters. The Multiplex transmitters always have the two-servoaileron mixer assigned to channels 1 and 5, and the V-tail mixer to channels2 and 3. Other transmitters are different or adjustable.4
