Wide Bug
From: Allan Wright <aew@...> Date: Thursday, October 3, 2002 10:49 AM Subject: Re: [BugHLG] Re: Wide Bug
Chris is correct, it's the ANGLE of the dihedral that you want to
keep when you extend a wing, not the amount each tip is lifted up
from level. If you keep the dihedral angle the same the extended
wing will have the same amount of yaw induced roll from the dihedral
even if it is a wider span. (give or take the additional drag effects).

John - I added one rib to each side for the Lil' Bugger and used
the stock dihedral angle. To double check I just measured to the
first rib in from the tip instead. It flies great and I was still able to
get in at 3.5 ounces. For LB2 I'm going even wider (possibly 44")
and using a thinner, narrower chord AG 30 seiries airfoil. I hope
to have it finished to fly this weekend.

Dan,
I like the idea of the added strength so I built with the added rib
on each side. I was going to adjust the tip height to allow for the
added length, but forgot. I ended up with a lower angle but I
haven't noticed any major differences. The angle is not all that
much different. The wing is bigger and thus turns a little wider
(but not all that much). It may be hard to find someone who has
tried it both ways, and with different angles, so just give it a try
and let us know. Good luck.

What is the consensus on how much dihedral to use for the extended
wing? Plans call for 5 1/8" at the tip of the normal wing - are you
simply using the same angle?
Has anyone noticed a difference in adding an extra set of ribs
versus increasing the rib spacing? Besides wing strength with the
extra ribs, would the airfoil be more consistent with more ribs
supporting the covering?

From: "Dan" <danstrider@...> Date: Tuesday, October 1, 2002 2:24 PM Subject: Re: 1/8" great size
John,
I bought a 1/8" micro carbon tube from Aerospace Composite Products
(TU-0002). According to the ACP website (www.acp-composites):
"GRAPHITE TUBES - Graphite tubes are the ultimate push rods since
they contain 95% unidirectional carbon fiber running longitudinally
and are covered with a light glass scrim. This design offers a high
stiffness to weight ratio and makes these tubes ideal for 1/4 scale
aircraft pushrods, and slope soarer and helicopter tail booms."
For lack of a gram scale, the boom deflects approximately 5/16" with
four US quarters placed 13 5/8" from the fixed end. I have 14 5/8"
boom from the end of the pod. With my convential tail (plans in
carbon bug phots), the hinge line of the elevator is +1/2" from the
end of the boom. I have photos in the "Dan E." album.
Best of luck and sorry about your last 1/8" boom.

Maybe you have a thicker wall 1/8th inch tube. I am glad to here of
your luck with the 1/8th inch tubes. I will have to try again. I fly
kites and I know that you can get CF tubes of the same size with
different deflection rates. Mine was real floppy (lots of

know the manufacture of the tube you used? Also was it a Pultruded

I must disagree about the 1/8" booms.
I have an extended 1/8" boom, around 14.5" inches out of the
fuselage with cruciform feathers, and I can easily hit 50 feet
during launches. In fact, I went to the Down East Soaring Society
thermal duration contest and consistently outlaunched a Taboo ($400
foam & fg hlg). Granted, this was an open class contest and it was
just four of us messing with hlg's afterwards. My launches are full-
discus as hard as I can throw. The Bug tracks straight up with no
elevator preset, and tracks supurb with a hair down and right rudder
launch preset.
Yes, the boom is somewhat flimsier than the 3/16" HOWEVER, only
during launches does the tail see enough air to deflect the boom.
Most flights do not produce enough force on the tail to deflect the
1/8" boom. I still have enough control authority to pull loops,
another high-force on the tail manover.
Indeed, the decreased weight has helped too. My times have
definitely increased. I flew a 3:23 after the DESS contest, second
flight of the day. My best time of 4:30 was also done with the 1/8"
tail and cruciform setup.
Remember to keep the tail light! With the extra long moment arm,
weight becomes an issue.
Just my two cents' worth. I feel an obiligtory need to defend the
1/8" boom with my successes.

Hi John,
Thanks for the report on your experience. I had been thinking of
building one with a 1/8" boom, so you saved me the disapointment. It
sounds like I should build a new wing with extra area. The
performance of the Gambler is awsome (based on the movie): much better
than my Bug in still air. Would you suggest any changes to the boom
length with a longer wing?

I used my same old fuse and didn't have any complaints. I have two
short wings and one long wing and they all work interchangeably. On
the new (2nd) fuse I just built I had to drill out the 1/8 boom and
replace with the 3/16th boom. Now when I put my wings on it they all
do a roll to inverted on launch. Not sure what I have wrong.
Everything looks correct by eye but something is obviously wrong.
Guess I will have to measure.

Hi all.
"Now I am going to build a new pod & tail using a 1/8th in. boom."
Just a word of warning! Don't make the same mistake as I did. The
1/8th is too small. Too much flex. I had to replace with 3/16th to
be able to SAL launch. It went everywhere but up. Did not try the
new pod shape. Maybe next time.

Ya Allen You're right, that size of increase is not enough to need
bigger feathers. I can notice that it is not quite as quick in the
turns as the short wing but, I found the short wing was almost to
fast in the turns. With the bigger wing I fly much smoother.

Allen, I only added 5 in total.
"I added right at five inches (the space between the 3rd and
4th rib on both sides is +-2.5 inches). I made a copy of both wing
sections and taped the third rib on one down over the forth rib on
the other."
I added one rib on both side and placed it at the location of the #4
rib (pushing the #4 rib out). That added the space of aprox. 2.5 in
to each panel. That is about the same as what you added I think. five
inches is about 12.5 cm. I left the tale and boom the same. In fact I
change the wings on the same fuse from the short to the long
depending on the day, wind, and lift. I used a little less dihedral
than the plans called for by mistake. I did not have the wing tips
set high enough when I glued the halfs together.

this is definately the right way to go if you're adding 5" per panel. I
was more conservative and added about 6cm to each panel with the same
ribs so I just stretched it out. I'm sure your wing has more area then
mind did and probably flys better.
Did you go ahead and increase the size of the V-tails or lengthen the moment
arm (boom) a little to help with maneuverability? My extended wing was so
slight of a change I didn't bother.

I did it with out recalculation. I built the wing on the copy of the
plans and just installed the rod in the first and last rib. Then I
placed each rib flat on the plans and marked where the rod crossed
the rib to know the location of the hole. That way I did not decrease
the strength of the wing with less ribs per/span.

Actually, if you don't add any ribs, and just stretch the wing by moving
all the ribs out proportionally, you can use the holed on the plan, you
just get a different curve to the leading edge. If you add ribs or space
the ribs differently then all bets are off and you have to recalculate
the spar location for each rib.

One other item!!! Don't forget that the holes for the wing rods have
to be moved to fit properly. Don't use the holes on the rib templates
other than for the first and the last ribs. Fit the first and last
ribs to the wing and use the rod to mark the position of the holes
for the remaining ribs right on the rib face.

Colin, I added right at five inches (the space between the 3rd and
4th rib on both sides is +-2.5 inches). I made a copy of both wing
sections and taped the third rib on one down over the forth rib on
the other. That way I had the same rib spacing. I also used .056 FG
cloth on the wing tips. I just sprayed adhesive on the tips and
smoothed out the glass. Then I dropped thin CA on it for a really
strong wing tip. I also ran the CF tube to the tip. I then sanded the
tube to feather it down smooth at the tip. I added thick CA in the
open tube where I had sanded it. I can't tell any difference in the
wing strength. The wing is not that noticeably larger than my
original but it sure floats more. The five inches that was added is
close to the cord so the % of area added is considerable. I doubt
that I will ever build another wing without the added rib.
P.S. I did add a considerable amount of washout by twisting the wing
and applying heat with my iron after the wing was covered. That
really helps the wing not to tip stall.

John,
Many thanx for the input. I've been planning to do the same with the
wing the next time I rebuild mine. Tail surfaces are broken now and
just too much else to do. I really miss having my Bug available, but
it will come around in time. I was thinking of adding about 6 inches
to the wingspan by adding some center ribs. How much additional
wingspan did you end up with by adding the additional #3 ribs?
Regards,

Great day for The Bug!
The last two days on my lunch hour I have had 4+ minute flights and
several 2 + and 3+ flights. The dead air flights are up by about 30 %
to 40% too. The secret! I have built a new wing with two #3 ribs on
reach side. I guess it is about the size of the Gambler. It works
great and is a real floater. It is not quite as quick to respond to
inputs as the regular wing but it makes me a much smoother Bug flyer
and it doesn't take much to make it go up. It side arm launches
straight, and climbs out really high. It seems more stable than the
smaller wing and has to have a great wing loading advantage. Now I am
going to build a new pod & tail using a 1/8th in. boom. I am toying
with making the pod taller and narrower to hold the servos vertical.
Not sure if I will do that, but I think it would reduce overall drag
and add more stability. I can't decide if I should switch from the V-
Tail (my transmitter will not mix) so I could dump the onboard V-tail
mixer. Anyway it flies great and I'm happy!!!!!.
