LM...unfortunately I dont think there is anyway of seeing the exact time difference.
evansb....my BushCaddy challenge generated a few other pictures of aircraft wtih rudders on the floats. Guess that may have caused some confusion. But yes, for what its worth, the picture posted by RR is an Avid floatplane.
Shutting down now guys, will check in later and see if RR's offering has been solved.
