You all have put out some high cool factor machines in your career, but this one had me giddy as a basket of kittens in a factory making yarn out of catnip.
Way back in the late 1900's when flying RC meant flirting with poverty, I had a moment of clarity while looking for another plane to add to the fleet.
It'd be sharing rafter space with some high performance iron consisting of warbirds and psycho aerobats.
I was eyeballing something along the lines of an Extra 300 in the 120 4stroke range that I thought I wanted, but it just didn't thrill me looking at the kit box on the rack. and that's when it happened ... my head fell out of my digestive tract, allowing for the realization that I entirely lacked a single airplane that I could fly with less than 2 pots of coffee and just chill with.
The Great Planes 20 sized cub followed me home along with a Saito 30 and some monocote.
in its final configuration it had a 14 oz tank of liquid lithium for a run time best measured in hours rather than minutes.
you'd be tired of flying before it would be out of fuel.
despite really only seeing daylight when actively flying, it would be retired with its monocote faded and becoming brittle.
In an attempt to actually try to run a full tank through it, my friend, his top removed via cutting torch International Scout, and I got this hair brained idea to get the Cub in the air and see how far we could get.
Full tanks, both truck and Cub, and about 70 feet of altitude, I brought it around for an inbound pass with about 400 yards to cover which gave us time to pile into the topless truck for a memorable road trip.
we started out of a field a few miles south of Gleason WI ... and I'd finally land on a random backroad near Stevens Point.
I ultimately gave that one to my Nephew after I moved to Nebraska. I always wanted another, and was absolutely thrilled to see one emerge from Flite Tests Area 53 and 3/4 lab.

Well this is probably the quickest "download plans to finished build" for me ever. I've been pretty excited about this plane for a while now. It went together pretty quick (its not perfect) but a perfect size for the school fields I fly in.
I also added a few 3D printed items. My control horns I printed out of ABS as well as some servo mounts that I can glue in so my servos can be removed later if need be. I also like linkage stoppers so I did that as well.
My wheels are a little small but worse case I'll just remove the landing gear.
and one with the cub and my bi plane ready for the air at the flying field!

Pictures should be fixed. The parts I printed aren't on thingiverse, I just quick drew them up. If you are interested I will gladly add them online.

Better Dihedral approach
As a scratch builder, I appreciate the approach they took with the dihedral on this model. Instead of the almost imperceptible curve in the root of the wing, they opted to go with a flat center section with obvious dihedral cuts on both sides. Bravo Josh or Dan or whoever finally listened to the frustration of using a straight edge on the wing root only to discover later there was a small break midway through!

I'm going to say no. This is a rather large plane and I would stuck with the recommended motor at minimum. I will likely also be using a 3 cells with the 1200kv motor as well. From experience with other planes in that size it really helps.
Canair, if you are in the states and want a cheap option for motor and esc, value hobby has the correct emax motor (even a cheaper gforce one) as well as ESCs. They also offer affordable shipping and have a decently fast ship time. If you run all gforce parts I bet you could get motor and esc shipped for $15.
Or just buy a power pack B and be all set with everything you need.

I got some cool horns printed from thingiverse but I have not seen a servo mount like you've made ... It would be awesome for you to share that one. If you don't want to post to thingiverse then I'll gladly take it over email rafy@ulight.me
thank you
update:
I found the servo mount https://www.thingiverse.com/thing:1662029
and here is the control horn I decided to go with https://www.thingiverse.com/thing:1967781

Do any1 suggest nice BangGood equivalent to PowerPack B engine (EMAX CF2822 1200KV)?
Hai-Lee said about easily damaged motor mount. That wasn't first time a read it. He also suggested HK equivalent Turnigy D2822/14 1450kv. I prefer something from BangGood.
I want ir as an equivalent for PowerPack B not only for Cub, but also for FT Explorer. What do you think please?
EMAX GT2210-13 1270KV
DYS D2826 2826 1400KV variant.
DYS D2830 1300KV variant.

Any of those 3 you listed would work fine. the first one is closer to the power pack C if I'm not mistaken. I've used the 1400kv model (turnigy, but i'm guessing they are all the same, just different color and sticker) and been very pleased with that motor. Worked great in a mustang i had. I doubt you would see a huge different between the 1300 or 1400 version.

Thanks for the reply.
Unfortunately, I'm in Canada and things take a while to arrive. I have a 1804 kicking around as I was just about to make a tiny trainer, then I saw this!
I do have some motors that would fit the bill - but my batteries are all 800Mah 2 cells or 2600mah 3 cells. Would the 3 cell option be too heavy for this? I'm wondering if it would screw the COG up too much.

Old and Bold RC PILOT
When I clear my workspace and start building mine I will be aiming to fit a 2200 3S or an 1850 4S. It will definitely be a little heavier BUT correct positioning of the battery to give the correct CG is the obvious way to go, (I will mod my model to make it happen if necessary).
I might even reinforce the wings slightly and add wing struts as well.
Just my plans for the design!
Have fun!

Can't wait to build it!
Dan, I'm not sure how the B pack motor compares to the few I have waiting for homes in my shop, but I was hoping you could help. I have mostly EFlite stuff. I have a Eflite 400, 740 Kv, 2 Esskay 400xt motors at 950kv, a 450 size at 850 Kv and 3 Turnigy 2826/6 2200 Kv motors. Will any of these work? I hate to buy more when I have so many available. Thank you

I'd try either the 950kv or 850kv with a 9" prop on 3s. I've ran 1000kv motors spinning 8" props without issue on many FT planes. Might as well try it with what you have first!
