Teckbot - you're touching on why I beleive this plane is so well accepted by such a wide variety of pilots. The speed envelope it can easily be flown in, from creepy hold your breath slow, to well into triple digits, is the widest of any plane I've ever had any experience with (lost count of how many planes I've had a long time ago). The R-70 designer tripped into a design capable of making anyone flying it feel comfortable, and look great while doing it!
For a clearer idea/verification of how well the plane has been accepted in the RC community, it's popularity can easily be measured/confirmed by the number of replies and views here in the thread at RCU. Compare those to any other plane you can find here for an idea of how popular it is? We're now over half a million views by guys following what's going on here. What's up with that? As somebody mentioned earlier, this thing has an almost cult like following!
