well after it taking me half a day to print out the plans for
the LazyDazy due to the fact that I had not updated my adobe
reader (Early versions wont print poster as I discovered after
many sheets of plans that were scrap).
I could not wait for the foam board so decided to try it with
normal 5mm polystyrene, went quite well and came out with a
weight of 1.7oz with no pod or electronics. Battery is a 900ma
so I may end up cutting a slot under the wing to carry it, will
have to see.
Well impressed with the airframe so far but may need bamboo
struts for strength due to polystyrene used.
Just a side note that I ended up fitting the bits that are cut
from the main wing and hot glued to the top of the wing support
to keep the wing shape when it is strapped down.
Well impressed and many thanks for the plans :)

Great. That's lighter than my model.
It took me awhile to get a nice flat glide. I couldn't believe
the CG could be that far back. Put some weight at the nose and
test glide with a small shove from shoulder height straight out
and slightly nose down (2 degrees). I add weight to the nose
for testing by making a quick foam board box taped into the nose
and adding pennies until I get balance about where shown on the
plans.
Note whether the glide is at about 5 degrees. If the plane
falls off or turns to one side check for balance side to side
and a straight rudder.
If the nose pitches up at all, it's tail heavy. If the plane
doesn't glide and just drops it could be nose heavy or needs a
slight shim under the wing trailing edge.
Once you dial in a good glide make notes, weigh the nose weight.
From shoulder height my LazyDazy will fly out 30-40 feet and
land on its wheels.
Packing tape is a good strengthener for foamies if you can't get
foam board. A lot of guys take the paper off anyway. So maybe
you are on a good track.
Funny story: I was anxious to try my Macchi 5 seaplane
yesterday so I took it out on the frozen lake. The surface was
too rough and it refused to budge. So I figured, what the hell.
Pointed it into the wind and put the throttle to about 2/3 for
a hand launch. Ooops, skipped the glide testing. It was tail
heavy. As long as I gave it power it flew, the wind caught it
turned it and it flew into the nearest metal object. Bam!
Broke the wing mounts at four places. But a five minute glue
gun repair and it's fine. Now with five pennies added to the
nose for balance.
The snow and ice are receding, maybe four weeks to green grass.

Well i ended up in town today and ventured into a hobby shop, to
my delight they had some foam board but only A2 so took the
plunge and bought 2 panels.
Found i could make the Tomboy from these panels so got the plans
and started to cut, Boy is this stuff strong for its weight. Got
all the parts cut out exept for the pod, glue gun gets plugged
in tommorow to assemble the plane then onto the power pod, going
to have to put the battery somewhere else due to it being
slightly too big to fit in the pod.
You only have to look at that styrafoam plane i built before and
bits broke off, It fell from the table and broke the tail off !!
(Its just too britle, now i have seen what foam board is like i
am hooked !!).
Just a quick comment on the tomboy plans is that there are 2
different locations for the servos, (on the fuselage they are
further back than on the fuselage sides). Not a concern at the
moment but could be confusing to some. I will just check for CG
and move either back or forth.
I need more foam board....I`m hooked....

Great! You'll like the Tomboy.
I have been revising the plans constantly. I'll correct that
servo location to where mine ended up. Before cutting out a
notch for it, slide it back and forth until it balances. Your
larger battery is going to need to mount on the lower side of
the fuselage somehow. Maybe cut a big notch for it.
I got the 909 spy camera working today. It weighs about 12
grams and takes very high def video.

Great, I have one of those key ring cameras, only weighs about
10g and cannot wait to video from the sky`s above.
I will post a picture when it is complete but not sure when I
will fly (Weather forecast shows no less than 20mph winds up to
next Saturday). Roll on summer !!!.

Re: Tomboy,
Finally got the power pod built, Made it 1/2" longer from bulk
to nose to accommodate battery otherwise as your pod. Next job
is to work out how to fasten pod on to stop it dropping down
then fix servos, I have got no rush as the wind is still blowing
good out there.

There is a bamboo stick just behind the bulkhead down low. A
rubber band goes across in front of landing gear, catches the
stick and back again.

Ahh Got it now so the bottom bamboo is wider that the bulkhead
and slightly higher, Many thanks for that info.
Just to say that even though the pod is larger it still is
looking good on the cg point (Further checks to be taken once
the servos and push rods are fitted).
Decided to get as much weight up front as possible due to the
fact that it is better to add 1g of weight to the tail than 10g
to the nose !!.
Been checking out poster paints (Acrylic) for decorating the
plane and looks promising but it would need a lacquer spray on
top I would think (Turns out very matt in colour) to give a nice
gloss finish.
Many thanks again.

Okay,
I decided to buy one instead of waiting for the water balloons.
Not very slow but impressive.
