Left stick = throttle
Right stick = Aile, Elev (delta mix)
3 position flap switch = wing sweep

On my DX7 I use the top left flap switch for the sweep. That being said, the idea of using the rudder channel (left stick) for sweep is kinda intriguing.. might have to try it.
I'm used to flying with flight modes on my EVO9 which are also on a switch on the left side of the TX so this is very natural for me.

got one built. this plane looks nice. though i didn't care much for the tabs as they're a PITA to cut.
i got the wings to swing but i'm having trouble with it closing or opening all the way. do i need to fabricate a longer servo arm?
right now it's set for mid open/close on ch4. when i turn the stick to the left it opens but there's still room for fully open, like wise with the swept version.
would the fc2408-05 with a 5 inch prop with a 3s?
not really looking for the 100mph barrier.
BTW, built as is, i gave it a toss with the elevators up acouple of mm and it went a good 30 ft.
awesome plane.
Thanks.

Glad to hear!
If you want to increase the range of swing then you will need to lengthen the servo arm. I use the Hitec arm that is listed in the manual but you could easily make one from 1/16 ply and simply bolt it onto a shorter stock arm. 50mm between hole centers is ideal.

I'm not familiar with that motor so I can't comment on it. You want a motor with more torque and less speed , i.e lower KV. The ideal motor is something with a 22mm stator that is 8~12mm in length and has a 1200~1500kv rating. This plane is an aerobatic plane so what you are really after is vertical acceleration and the best way to get that is with a larger prop. You will get better performance from a 7" prop with less pitch than you will from a 5" prop with more pitch.

There are lots of motors that would work well, here are a few:

-AXI 2208-26
-Emax CF2212 (cheapest)
-X-motor 2826CA-12T
-Eskay 400XT
-Little Screamers Purple Peril
-Grayson GH2212-10 (combo w/esc is only $33!)

I guess I'll need to order some more foam and I guess a higher powered
servo. About how much torque do you think is needed for wing sweep servo?

How much flight time are you getting from the TP1320's?


Excellent looking plane!

I'm getting 6~10 minute flights from my 1320 packs depending on how hard I push the plane. Lots of vertical climb outs = less flight time. My TP packs are warm after a flight - my green Evolite packs run cooler. My current setup with LSPP and APC 6x4 is pulling 12A WOT static.

Hmmm, I get over 7 minutes with my LSPP's turning a GWS 8x4 DD with some cheapo 20C Hobby City 800mah 3 cells. I would have expected longer flight times with the 1320's. But I guess it does depend on how much juice you're giving it.

You may be right.. I tend to run my packs on the conservative side to prolong life.

I fixed the bug in the plans and reposted - also added grids for easier alignments of tiles.

DXF files? Are you planning to laser cut?

I have a homemade cnc router that I want to cut them out on.
When I finished building the router, I started cutting planes out on that, it makes all the tab cutting so much nicer
