EZ KrakYak v1.0

[AIRFORGE]

Understood. Looking at the plans as-is, it appears wingspan will end up approx 15.25" (as opposed to 17.4" if I had resized to follow incorrect scale guide). Was just using that measurement to confirm in case others are following along or have already built.

Yes. Correct.

AIRFORGE updated EZ KrakYak with a new update entry:

Corrected Inch/CM Scale

Corrected the Inch/CM Scale.
No correction to actual plans.
Good catch @dmco ! Thank You, brother!

I’m up scaling this to have a 30in wingspan on Fpack.
Hope it works good!

You'll love it! I did a 31" with an A and an F pack, too. Can't post it here, it's too much like the original Crack Yak.

Cool! did it work good? was it able to fly indoors?

Yes. I never tried flying/hovering indoors, though. It does need minimal wind outdoors.

Do you have any idea what was the AUW?

I don't know the weight of the 31". A very rough guess is 400 to 500 grams.

I was just wondering if mine was too heavy… apparently not, it weights approx 310g.

 

[Jo's squadron]

You were right about it being very sensitive to wind, like I have never flown a plane that flies this bad in wind. But I tried it in a gym today and it’s a little too fast for my taste, but it works ok. It hovers pretty good too.
I think if I wanted this to perform good indoors I would have to get it at 200-230g.

Here are the electronics that I used (pics coming soon).
2205 2300kv motor
5x3x3 prop (I think)
40amp esc
4x 9g servos
6ch RX
850mah 3s 75c battery

Finally got around to building my 2nd EZ KrakYak. The first one I made the mistake of peeling all the paper, and it was too flimsy. I'm using the AR3201G receiver with built-in ESC from CrossoverRX and two of their micro servos. The FT EZ Power motors plug directly into this receiver. Instead of waiting for parts to arrive from China, I found that Buzzard Models in Minnesota is a great supplier for these parts. I haven't flown it yet, but I'll give a report once the weather cooperates. A big thank you to @AIRFORGE for providing these plans!
