Re: Re: Double strand motors?
Hi Dave,
Actually, I hadn't thought about starting with 1/4" as I have never
had occasion to use that size. I and most of my friends always
(generally) use 1/8" of
various vintages in whatever we do and strip down to the appropriate
size for different classes.
In this usage, I don't think the weight of the knot is an issue. If
you can use up most of the turns, then you may worry about the weight
of the knot; super light classes are another story. That helicopter
is heavy and takes a lot of power to move it. My heli. was getting
flights of 2:48 (living room) and 2:56 (30') using .125 with lots of
turns left. I made up some .140's but never got around to trying
them. Lazy I guess. I gave my girls who placed second at Nor-Cal
State some of both but I don't know which they used. As I said
before, you taylor the width of the motor to find what works best and
the stopwatch doesn't lie.
