<DIV><FONT face=Arial>Actually, there is an advantage to swept gear. Most
current designs have the gear mounted forward of the wing LE. As a rule of
thumb, it's best to have the axle split the LE of the wing for landing purposes.
As you move forward of that point, you have a plane that will tend to be very
bouncy on landings. Rearward of that causes noseovers on landing. The sweep in
the gear ala Bolly, helps position the wheels in the optimum location. I've used
Bolly F3A Longs on my last four pattern planes and they've been flawless on both
pavement and rough grass. The flex seems just right to me to avoid some of the
fuse damage problems I've seen caused by some of the stiffer gear out
there.</FONT></DIV>

<DIV><BR></DIV><BR><FONT face=sans-serif size=2>If "swept" gear are preferred
for the appearance, and impact form fit and function, that is, there is a
performace trade off to look cool, then all who prioitize in such a manner
will be unhappy with a gear set if we make it. My priorties going
forward will be:</FONT> <BR><BR><FONT face=sans-serif size=2>1. Performance
=stiffness, weight, twist- balanced by</FONT> <BR><FONT face=sans-serif
size=2>2. Cost= material used, labor and cycle time</FONT> <BR><FONT
face=sans-serif size=2>3. Cosmetics= need to look good BUT it is #3</FONT>
<BR><BR><FONT face=sans-serif size=2>If Cost were no issue We could make a
gorgeous set of ultimate performing gear, but cost is a large issue and if
AeroSlave does not follow through it will be because of cost. We must be able
to cover our non reccurring costs of engineering and especially molds
which are very expensive. I am always a bit hesitant with the pattern crowd
and the need for the plane's components to be prettier than the pilot or even
his wife! I understand paint finish and such but making a landing gear
perfectly gorgeous when scutinized up close may add $25 per set. Some will say
this is a requirement, some will not. This is what I am trying to figure out
at the moment. Lance and I have a big handle on the technical aspects, but
things like sweep, finish etc can kill this (from a business apsect) before we
get off the ground. Swept gear will require more molds =$$$. Almost everyone
cuts a single gear into a left and a right. </FONT> <BR><BR><FONT
face=sans-serif size=2>I do find all this input interesting, but Lance and I
will have to figure out how to proceed. This feedback about stiffness,
bouncing, toe in etc is great. We have prototypes performing very well, but
now we need to productionize the design. <BR></FONT><BR><FONT face=sans-serif

face=Calibri color=#004080 size=2>Gray, the toe in twist issue on the ES gear
was definitely an issue I ran into, at least with the taller electric version.
Also, on crosswind landings if I didn’t straighten it out just right before
touching down it would start doing a sideways hoping action with the forward
leg acting like a spring. I think you may have seen this in Lubbock. This is
the only set of gear I’ve ever experienced this with. More ridged gear don’t
seem prone to this behavior.</FONT> <BR><FONT face=Calibri color=#004080
size=2> </FONT> <BR><FONT face=Calibri color=#004080 size=2>As to
straight vs. swept, straight may be easier to fabricate as a first attempt to
get something to market and would provide interchangeability. On the other
hand, if you dork one half of your gear you still have to buy a whole new set
and there’s not much you can do with the other half, unless you have a habit
of dorking gear. The swept look is most definitely nicer. I’d go with
what you think will sell the best, based on sex appeal, and will be
structurally sound. I wouldn’t worry about giving the multiple gear dorkers
the ability to use either half on either side. Besides, multiple gear dorkers
will help keep you in business. </FONT><FONT face=Wingdings color=#004080

the IMAC style planes that they are designed for but too heavy and way too
stiff for our use. <BR>I went through their website and picked a gear based on
dimension of the ES. 2+ ounces heavier and twice as thick with zero flex.
Broke the gear out of my Black Magic many times when hitting small holes in
the runway. Rick donated his ES gear and life has been much better.
