good post..i feel it takes a great amount of concentration to fly these acft.the monetary investment,the safety issues and procedures of operation demand respect and attention much the same as a full scale jet jock may go thru,i see no difference in this per say.i myself go into my flying mindset when i commit to a flight and quite frankly i find it very irritating to have silly or out of the way conversations during this time.i am reviewing all the steps necessary to start up,acft performance characteristics,which way the wind is blowing,etc...and the flight plan i am going to execute etc.after shut down and cursory acft inspection,i review my flt mentally,and give critical thought as to what was less than par in the flt.after that i am all for casual conversation etc.i feel this sport is for those of mature mindset.i particulary cannot stand those who want to have a conversation with me during my flt...very distracting to me and selfish for those who wish to do so.if the words are not related to the flt please save them for later.i also fly a 33% imac bird and the same applies if not more so.i have seen guys who got jacked up bad by not paying full attention to what they were doing and a 28 inch prop swung by a 100cc eng reminded them of that fact.flying model acft is a huge responsibility as well as an enjoyable sport enhanced by a good dose of proffesionalism.thx guys...and gals.
