Simple Stick V1.4

[BATTLEAXE]

Here's a challenge. The plane is so tail heavy, I've added 3 oz. To the nose, a spinner, and if I were to extend the power pod 2 inches out of the fuselage, I may, may be in balance. See picture with the power pod extended. I can build an extension and pin it to the fuselage, but what flight characteristics will I compromise?
Am I better off just adding more nose weight?
I think if I zip tie a full can of Coke to the nose that may do it. - won't fly but cg will be on!
any advice will be appreciated.

Bro you need to chop three inches from behind the wing, this will bring the tail weight out of the airframe just in bringing the tail closer to CG. Just that flat section behind the TE of the wings bottom panel. Its easy to graft back on. And the flight worked out really well too

How big of a battery do you have in it and where are you positioning it?

I moved the wing back 1", and it did fine. I also have my tail servos under the wing, in the fuse.

On mine I flew anywhere from a 1000 mah to a 2200 mah without issues, although the 1000mah was a tad tail heavy. However I know lots of the others who have built it have had issues with it being tail heavy so I think I’ll adjust the plans a little to compensate. Also, for some reason one of the CG marks is wrong - it’s supposed to balance at the front edge of the spar.

I flew it at half the spar CG, it was fine. But Then again i cut 3 inches out of the tail. But with a 2212 and a 2200 batt all the way to the front with the ESC right underneath the motor. And with a symmetrical wing I found the glide was nice to, landed so soft

It did fly nice and it will get more sky time for sure. Wide speed envelope and almost zero ballooning. Once these FT Simple Stick plans come out then it would make a decent comparison to see what the results are.

Actually now I want to design my own, see what happens

I would definitely build one of you did!

Don't tempt me, you know I will.

I might have a KFm wing in the up and coming future, simple but fast

Thanks for the advice.
Instead, I cut the top of the fuselage and moved the wings back about 1/2". I probably should have gone 1" because that plus about 4oz of nose weight got me close to balanced with a 2212 and a 1300 3s battery

.
Now my question is, where is the real CG? Checkout this picture of the plans, one side has the cg at the forward edge of the aileron servo and the other side has it at the aft edge of the servo.

So, it looks like the mark on the right side of your picture.

Yup - it’s supposed to be the one closer to the LE of the wing.

are there tiled plans available? little knew to scratch building so don't quite understand how to print out the plans on standard printer so that I can cut and paste them to standard foam board

It's done. I haven't flown it yet but it's painted for maximum visibility and the honor it's Ugly Stick heritage!

still can't quite figure it out. I did set up like this but when I print it only prints first three tiles

Try changing "Pages" to "1-12"

did that and still just get the first four tiles.

ok, switched to adobe reader and its working ok. I was using .pdf element and just couldn't get it to work. thanks all!
