flying is a good part of trial and error, personally I have worked hours on aeromodels and that flopped in front of expectant crowds. But due to some bug in my head , I feel that it only made me want to come back to the field with another design. And keep coming back till I had a flying model.  It was not necessary to have a perfect model, but it was necessary to have a flying one. ..... just my 2centse

theres no place for any negative emotions , only positive expectations
