Just out of interest @Steve Fox, how much heavier than a stock FT Cub is yours? I assume you're using White foamboard from hobbycraft?
Sorry, only just seen your post, my foamboard comes from a UK Ebay seller called papergourmet, i buy it in packs of 10 A1 sheets.

Forget FT specs, the cub flys much, Much, MUCH better weighing more!
FT specs are only good for absolute zero wind!

My cubs come in at around 890g with a 2700mah 3s and are 1.1kg with a 4200mah 3s and 1.15kg on a 4200 3s and a storch wing but lift on that wing is huge compared to the stock cub wing!
my specs are in the first post, but heres my full specs and links :)

Stand alone voltage osd i use, works well but under reads by 0.6v and so im showing 9.4v when im really 10v but like a fast or slow clock, you know what it really means and i may just have a bad one, others may well read bang on:

future builds with no FC will be using this OSD for on screen voltage:

it can be flashed with a standalone version of MWOSD and be used for a voltage display and you can configure it to display how and where you want, it can also act as a stand alone gps decoder (with a gps attached of course!) and display speed and distance without an fc with MWOSD firmware flashed!

Oh thanks @Steve Fox I might give that guy a try, if you have a sheet complete would you mind weighing it for me please?

I built a cub a while back and even ended up having to do the same rebuild you did on the nose (and the same ESC mods too lol), but it flew crap so I eventually gave in and bought a tundra while they were available, that flies great and has been rebuilt several times already but sometimes I just want to chuck around something and not have to worry about turning a £150 plane into a lawn dart so was thinking of building another just for the fun of it.

Update on the Giant Cub, winds were about 20mph here today so I took advantage of that by flying the giant cub backwards! Did you know that you can land a plane backwards? Also if you land a plane backwards does that distance count towards the length of the landing? Then things took a turn and when a strong (30mph) gust of wind shot the plane up and back the battery came lose and fell into a bean field, never to be seen again. The plane did amazing, with no controls it glided into the thick bean field and took no damage. Then I figured "Hey, why not try that again but secure the battery a little better?" So after securing the battery by using some velcro I did the exact same thing again. Fell backwards and lost the battery. The plane once again fell very gracefully and was not damaged. Unfortunately however I just lost $30 in batteries because I was too excited to go flying but oh well, lesson learned. I have two more 3s 3000mah batteries on the way and I am designing a battery holder to be 3d printed. Overall though it flies very well and now it's time to make it look pretty! Videos are still uploading so I will let you know when that's finished. When this is all finished I'll make a new thread for it. :^)

So glad I found this thread. I was really wanting to get into the hobby again (many many moons ago I built an ARF balsa trainer and a friend helped me fly it a few times - plus my Dad had several planes - including a yellow Cub).

But the costs of the power packs on top of the transmitters was really bumming me out.

But the Banggood prices seem doable and if I crash and burn I don't feel so bad.

Two quick questions:

1) Does your club fly better with the 2700 or 4200 battery?
2) I'm torn between the Simple Cub and the Simple Scout. I've heard both are good but some suggest the Scout is better for beginners, but then the Flite Test guys say a Cub is great for beginners. Any thoughts?

Note: My daughter is a HUGE HTTYD fan so we are building a couple of Twin Sparrow dragon themed planes too.

My vote goes to the Scout, on a C pack sized motor with and 1800-2200 3s. Welcome to the forums BTW :cool:(y)
Thanks. That's the way I'm leaning. I found a cool paint scheme for the Scout and love the WWI theme of it - just remember my dad's big yellow cub and it pulls at me.

I will probably start with the Scout and then build the Cub later. That's the awesome thing with the foam planes - you can just keep building with $1 Dollar Tree foam.

Yeah I love them, built over 30 planes now since spring, so cheap to build crash and repeat. I like the diversity of experiences you get with them too. The Scout will be your average trainer which you can grow into as a pilot and it will help you get ready for any warbird like the Spitfire, P-40 or Mustang, if you are into the warbird thing that is. It will also give you the basics of building techniques without getting to complicated. I do better at the building then the flying, hence why I have built so many in the past 7 months :LOL:

If you are going to build the Scout I do have a build thread which I started awhile ago which documents my build, plus a couple others have hopped on and documented theirs. If you want to get some tips for building and see others builds and maybe document yours it is a decently popular thread that people chime in on all the time. It could help you out and your experience could help others, here is the link and check it out, you might like it.

Here are a couple of my Scouts I have done:
20190819_211107.jpg

This first one is a stock build, stuck to the plans for the most part, I did change out the pod idea for a fixed firewall and top opening battery hatch for convenience...
20191003_174430.jpg

This one is insanely modified and even had a set of floats for water and snow.

People do all kinds of mods to their planes and you will find as you get into the building and flying that you will want to do mods of your own after awhile. Fixing and repairs are really easy as well, we all have crashed to various degrees so there is a treasure trove of tips and tricks here in the forums. Its all about having fun!

I did a 186% Cub not long ago. the build was a little bot of a PITA to address the changes the enlarged plans introduce, but it flies way better than the 100% version. PropDrive 2 3536 1400kv, 2x 4s 1800 in parallel for balance, 10x4.7SF. A current fav to fly...
Actually i just started a 130% Cubbish Kitfox type of build. Just got the fuse plans cut out with the profile mods planned. Got it worked out where it will run an 11x7x3 on a 5450mah 3s. I have some different plans for the wings as far as the tips and the ailerons. I still have some research to do but it will be different thats for sure.

What size wheels do you plan on running?

Have you started a thread? I'm a die-hard Kitfox fan! Mostly because of Trent Palmer's awesome plane...
