OK, so I found out the hard way that there
are some topics that have been pretty much thrashed to death! And I, as a
newcomer am finding out what they are.. so if you have any
questions please take a look down the list here first as they may well
(probably have) been covered before. Trouble is with newsgroups, we get
lazy and would just rather ask a question again than go dig through the
archives.. Well digging through archives is not my Idea of a good time so
I like the lazy approach :o)
But now we can all be lazy because I will
and try to put allot of the most common useful stuff on here.
I asked the question about glues and what types are the best BOY was that
popular ....NOT!!, seems the glue wars was discussed at length but I did
get some useful information, hope it helps you too, Remember this is what
other people are doing, please make your own decisions about what is right
for you and use the information here at your own risk.
I asked was "T88 or Excel One?"
Ease of use
right from the pot
Speed of use
the same so Shop around
Ok, so that's a start, all in all these two
come out neck and neck, so I guess the answer is go out and try them both
and make up your own mind. In fact more than one builder said they
actually use both. If anyone has any more to add I will be happy to
stuff it into my little chart there., just drop me a line jeff.@boltblue.com
Center of Gravity
is a very common topic. It is pretty crucial to keep the C of G on a
Ragwing Special within in the limits as from all reports it does tend to
be tail heavy, Having said that Roger was able to do a fine job on his and
after looking at the video it certainly flies strait and true, but he did
trim off quite allot of weight by making the tail thinner. Bear in mind
though it was built an an ultralight. Keeping tail
weight to a minimum seems to be the general rule but the nose
section can be extended or packing can be used behind the pilot, (as I am
a bit of a fatty this is what I intend to do) I am currently 190# but as
this is the Christmas season I don't expect to stay that way.
I think the average 40 - 50yo male weighs 180 - 220 these days anyway
(well I feel better if I say that) I forget which builder it was who said it
but the phrase "Add lightness" seems to sum things up rather
Landing gear seems to be a hot topic too!
as many builders think the standard gear isn't quite up to the job. Some
are using the bungee option some are just relying on tire pressure and
rigid struts and others are using a design by David
Morrow which incorporates small springs to act as the suspension.
There are other options too, so once again, each unto their own.
More on this when I get time or when more information is available to me..
remember, I'm the new boy here and I rely on the more experienced builders
for my information.
Tailsprings can bend so a few
builders are using Fortal aluminum (7075-T6) instead of the
6161-T6 suggested in the plans. I was given a link to a good supplier of
Issue -- Wing incidence. Extensive dialog in the archives. Almost
everyone agrees that the upper wing needs 2 to 3 degrees more than the
lower, as per plans, to provide gentle and controlled stall characteristics. Most
feel that both wings need a bit more total incidence
to adjust the flying attitude of the fuselage to bring the tail
up a bit.
The cable/strut attach points on the spars
need to move outward 1 inch to allow the cable tangs to clear the
adjacent rib without cutting it for clearance.
The internal block must be cut
(Thanks to Lynn Dingfelder for the
this just doesn't seem a viable proposition anymore, I wanted to build
mine as an ultralight but have had allot of ...hmmm not really
negative feedback, but allot of teeth sucking and head shaking. I don't
want to reinvent the wheel so I will hope the legendary "Sport
Pilot" License will make my life a little easier when the time comes
(September 2003 last I heard) Not saying that you can't make the Special
an ultralight if you don't want to though.. I'm saying my choice was the
again. I can't decide what you do with your aircraft, only relay
information that I have sifted through and come to my own conclusions
about. If you come to a different conclusion I really would like to hear
about it, I am always open to new Ideas.
will be added as I learn it
