i was gonna add wood strips inside the stabs through the hinge,but i figured for now the outside will do.ive watched vid reviews on this plane in kit form and many complaints about too much stab flex and tearing.
this ones alot lighter and straighter.
and im still lighter than the old wing,unless i add half roll of packing tape.....slightly over.but i wont be using all that tape.

ive doubled the foam on belly for landing gear and added wood backing,installed the landing gear,i got bigger wheels to put on.
i think ill be right at the .9 lbs flying weight without battery.
im .97 lbs with the old heavy motor mount,so im going to build new lite to compensate for the landing gear support.
wheels and gear came from a 35" span parkzone cub

I have been following your thread with some interest. Some very nice work, but one suggestion,
get a sharper blade!

I am working on a FT Alpha now, but my next build may be a 150%, 57" span version of the
Simple Cub. With 8" wheels?

i was just telling myself that,im using hobbico #11 blades,my hard desk i use for a cutting surface keeps eating the tips.....lol.
sharp blade makes way better cuts,but i figured this will be a basher for all my friends to learn on.
this also getting my feet wet in a first time build.....and ive learned a few lessons already.

i cant wait to see your build,if your using the same plane just scaled up,make a note about the missing lines and non symetrical fuse shape,my first one came out with 1 fuse half 1/8 taller than the other by following the printed plans.
maye its the way my printer printem....im not sure.

How did you print your plans, tiled, full size? I have had that problem with tiled plans, but never
with full size. I print from the PDF at what size I want directly to the printer. I have a Brothers
Laser Monochrome for plans, $75 cartridge will print about 5000 pages. Couple years for me.

I use a cutting mat and #11 surgical blades. They don't last as long as the #11 hobby blade, but
they are sharp. I use hobby blades for non critical things. I have 12", 18", 36" and 72" straight
edges handy at all times, #2 pencils and a electric sharpener next to the work table.

Main thing is to be comfortable while you are working! Main thing!

The printer should print the full size in tiles on it's own, tell it, Poster, 100%, With grid lines,

When you are old, single and unlimited resources, you can enjoy life.

Also, RC is not my primary hobby! I have a much more expensive one!

thanx for the tip,i tried the judi seajet in poster mode 100% and i it printed fine.
ill have to try the cub again,but it still bothered me that the fuse wasnt a mirror image.

we all have other hobbies,im into astronomy,airgun target shooting and kayaking.
always another exciting hobby to pull us away from other hobbies.
nice cycles by the way.

ive made my target weight rtf without battery .9 lbs.
still have cleanup of seems,maybe some added packing tape on bottom of fuse.
i wasnt sure i was gonna be under 1lb with the added landing gear and support ive added,but it all worked out well.i still need to to order the proper size weight battery.the 2700 i have is .4 lbs,ideal battery is .2-3lbs .....im thinking a 3s 1300-1500 mah will be plenty.
sofar the new cub is 3/4lb lighter by switching to $1 foam board over the walmart board.
i still have to go get the bigger wheels i have stored at another location.
but overall im very happy.
gonna build the ft old fogey next....cant wait.

Don't get obsessed with the weight thing. I make copies of profile 3d planes using DTF and they
are always heavier than the original. They do how ever fly better in wind than the originals did.

Weight can be a friend. Not gross amounts, 10 to 15% is fine.

i just weight total weight with my woreout hk 3s 1300 mah (88 grams) and im right at 1.2 lbs ready to fly,just the completed plane .97 lbs.
im happy with that.
if i throw in my big 2700 mah battery im too heavy at 1.6 lbs,the first cub i wasnt worried about weight.....but now i am....lol.
so i ordered a budget 3s 1300 mah for $13,be here next friday .
my curret 1300 mah cant handle the load,rpm drops fast.
i been using it strictly for my fpv moniter and equipment for the past ferw years so it never really had a discharge command.
