There seems to be some confusion here in that Reflex is being confused with the one that has the physics wrong... It does not... Granted, it is not the real thing but at times it is very hard to tell... It is as close to the real thing as I have seen... I have owned FMS, RF1 and RF G2 and now the reflex... Reflex kills the others BUT there is no where near the models around for it as G2 and much of the install ends up being German... Not the models or flying so no need to worry... It is more the folder names and what not... The flight characteristics and physics are excellent... Even the Fokker Dr 1 has the flat bottom wing problems when inverted... It is an outstanding value in that it costs less than G2 with the price for the add ons... I hate that it has no transmitter of it's own but it is a small price to pay for such an excellent produce...
