Greetings Larry,
I'm fascinated by your email. Please tell us all more as to the
plan/construction/weights of the model used. Also and in particular,
details of the tiny VP prop mechanism that you used - many will know
that this is a particular 'hobbyhorse' of mine, but I'm sure we'd
all be fascinated by anything you'd like to share.
This might be of interest to any 35 cm flyers out there.
Thanks,
Nick.
