Nigel,
I used #4 welding cable which was nice and flexible and not very expensive,
but I remember when I was bringing the 25' roll home thinking "darn this
stuff weighs a lot"
I suspect that the thick flame proof rubber insulation added a weight
penalty over the cable you used. I really wished I weighed it at the
time..... maybe I'll buy a short section and do a rough calculation.
I tried to pay attention to weight in my aircraft, it came out at 860lb,
about average for a 914 mono, but I often think until you have built an
aircraft you really don't have a great appreciation of its importance. Some
people have built 914 monowheels that have come in at 790 lbs..... I sure
wish mine weighed that.
I look forward to seeing your calculations of the "battery in the back"
weight trade off.
Regards, Paul
