BF109-G2 Master Series style - 46" wingspan 1.0

BF109-G2 Master Series style - 46" wingspan - An involved build with prototype lines and some nice details! Oh yea - she flies quite nicely, too!

A rather sturdy master series build with a 46" wingspan that has a nice glide path and flies quite prototypical on a 3S battery with a 1120kV motor. I've attached a PDF build notes document to get you started until I have a chance to do a second build with more pics and perhaps a video. Some aspects of the build are a bit tricky, but I hope to have covered them either in the previously mentioned doc, or in small notes throughout the plans. As designed, it can be built with or without...

beautiful fuselage but a poor leading edge shape of the wing，maybe a round leading edge will prevent stall and make the roll stability better

I contemplated the tape and fold method but when I started I did it the latest FT style. I agree I'd prefer the rounded but to get everything to fit right the size needs to be a bit longer. I'd like to do something different with the VSTAB as well. Maybe even a square tip wing option as well 😆 But first I'll need to see that the rest of the plan works as laid out and I remembered to update all of the parts as I went! Thanks for checking it out and the suggestions!

One can always add half a balsa dowel or half a wood dowel to create a better leading edge if one wished. Even using an iron to round the leading edge if you preferred.

Looks great thank you for sharing.

I saw someone do that somewhere online. maybe I'll give it a try next one. I'm thinking I'll probably be making at least 2 more of this one before I start something new. I'd love to hear how others do building it...I hope the attached instructions help!

I think I didn't have it in the instructions but I figured I'd add it here too... when I build the wings now, I add "tubes" made from stiff paper or thin card stock to give me a clear path for the wires to the aileron servos...

See pic here:

on this build you can see the lengths easily... I didn't add them to the plans at all. There's an angle cut on the center side to allow to easily drop the wire into the hole and let gravity to its job. I used a longer extension attached to the correct length of extension, drop the extension down through, attach the servo, and then pull the wire back. This is the view once the wings are attached...

using paper to make tubes is a great idea，I was always botherd by making wires through the wings

bwarz updated BF109-G2 Master Series style - 46" wingspan with a new update entry:

STL file for 3D printing exhaust

This is one side - you'll need to mirror the part in your slicer. It could use some tweaking, but it turned out pretty well and I'm not motivated (yet) to fix it

Read the rest of this update entry...

I hope to be printing the plans for myself tomorrow and getting started on a second build to see how clean the plans are. Hopefully they're close for anyone who might have downloaded them and started a build! If you have and find any problems let me know!

Any chance we can get a version of the full plans, not tiled? For those of us with foam cutters

I really wanted to do another build based solely on the plans as I uploaded just to be sure everything is good. Once I'm confident the plans are fully accurate, I can drop the whole set in another upload. One question tho - would it be easier if they were published in 20x30 size multipage (easy enough to open in Inkscape page by page) or just one big pile of parts on one page? Asking for a friend

LOL just saw John O's BF109 pics - I guess my build ain't so bad (shameless pat on the back to myself ) One thing that I saw on his that I've been contemplating how to do is the machine gun slots in the top of the cowl. I was going to do a 3D print design, but now that I've seen his I should figure out how to do it with DTFB (or keep it even simpler with cardstock). Perhaps back to the plans!

On that note - any thoughts on how to do a concave bend on foam board (paper on the inside side of the bend) or is that never going to happen on that small of a radius? Hmm.... I could just have the foam facing out - wrapping it around a round pencil worked easily enough...

 

[bwarz]

After a brief time of thought and a lazy use of the blade, I'm thinking I can accomplish the gun slots quite easily and accurately with a pattern to use after the fuselage and hatch are built. As half of the slot will be on the hatch, it'll probably end up much better in case the hatch doesn't alight well (like when I build mine lol). If I forget to add it later, trace pattern, cut the slot out - on the side of the slot closer to the centerline, cut straight down, on the side close to the wing, cut more horizontally. When done, use a pattern-to-be of the rough shape cut out of manila folder or heavy paper (not quite card stock), round ot a bit on a round pencil or dowel, and squish-fit into place. If it sits well, glue into place and carefully trim the excess with a very sharp knife...

 

[bwarz]

turned out pretty well? I need to add the template and patterns to the full file. I like cutting it after everything is assembled... it really helps things be spot on with the slot being in the hatch and the skin A.

I also added the exhaust covers (fit lack of a better description). They need a bit of angle trimming to fit, but once you look at the parts you get the idea!

 

[bwarz]

I've added a single sheet with drawings for a few details - the machine gun channels in the top of the cowl and hatch as well as the 'exhaust covers' if anyone is interested. I will be including the parts in the overall plans once I've rebuilt from plans only...
