IMPORTANT NOTIFICATION!
I went over the plans that I submitted again this morning less tired and I see some things that might confuse people trying to build it so here are a few comments for you to make sense of things that are missing.

Don't cut the black axis lines on all the pieces that have them, those are placed there for reference of the true axis line up.

The top piece out of these two needs to have creases made to it on the black lines NOT cuts, the bottom piece stays uncreased/untouched.

This is the wing leading edge fold over area, that needs to be 50% scored and then double beveled on both sides of it.

Some pieces have cavities on them that need to be cleared out. On some pieces this was marked exactly like FT does on some pieces not, so bellow are pictures of some pieces that need cavities cleared on them between the 5mm or 10mm lines. I might have forgotten some but I think you get the idea :).

URGENT NOTICE
Today I went out to the field with my new set of wings that was using these plans and realised that I might have uploaded a wrong file or haven't updated back from a print file into the originals, one way or the other I realised the problems. The top and bottom parts of the wing are not carrying a consistent wing cord, the top part is missing 1 cm to it making it not sit properly in the wing bed on the fuselage. The bottom is too long by 1 cm making it interfere with the ailerons. Sooo I have fixed the plans and am going to rebuild the wings using them this afternoon in my shift at work (hopefully) it will be quite because today it's the end of a weeks holiday here. I'll update the plans here once I make sure things are ok.

mayan updated Howard DGA-6 aka Mr. Mulligan with a new update entry:

URGENT FIX

FIXED ON PLANS:
# Wing top/bottom wing cords have been adjusted based on problems that have been dedected.
# Missing markings on the planes.

ADDED TO PLANS:
# Vent holes on the fuselage for electronic cooling.
# Velcro strap slots for holding down the battery in two locations for different sized batteries.

I added back a few peices to play around with so just make sure you ask me if you are not sure if a piece is in use or not. Only 3 pieces have been added that I want to...

Hey all, quick question here. From those who downloaded the plans has anyone tried to build the model?
