The kit comes with EPP wings and a center section, balsa elevons, fiberglass spars, aluminum motor mount, coroplast winglets and bay cover, and 5 mil laminate.



The center section has the bay pre cut in the V2 kits.

I need to finish my runt. Its been haunting me since I first got it and rushed to build it..... and have yet to finish it.

Nice! always wanted to have to flinch, but don't have so much money so will stick to scratch building. Will follow this thread! Hope it will fly as I've heart it would.

Yeah, the runt looks like it would be fun.

 

[C0d3M0nk3y]

Nice!

Thanks.

Hope it will fly as I've heart it would.

Me too.

Bottom spars glued in with brown Gorilla Glue.

 

[C0d3M0nk3y]

I'm using a Cobra 2217 2300 KV motor, an Emax 40 A ESC, and an HW 6x4.5 prop.







I'm using Emax 14.8 g servos.



The receiver I'm using a FrSky X8R.



I'll be powering everything with a 3S 2200 mAh battery.

 

[C0d3M0nk3y]

Elevons cut and cutouts made in the EPP.

 

[C0d3M0nk3y]

I painted the motor mount. I masked off the part that would be glued first.

 

[tneun]

Wow, that paint job already looks promising!

 

[C0d3M0nk3y]

Thanks. Just waiting on some warmer weather to paint the rest.

When I started this build, I wasn't planning on using the included coroplast skids, but I've changed my mind. They come in 4 identical pieces. I glued them into 2 sets of 2 with some goop.

 

[C0d3M0nk3y]

Painted.

 

[C0d3M0nk3y]

Laminated.



This was the step that was most intimidating for me before starting this build. I think I did pretty well for my first try.

 

[C0d3M0nk3y]

Glued the winglets on with white Gorilla Glue and glued the skids on with goop. Then I reinforced the seams around the winglets and skids and sealed the leading edge of them with goop. I also put the RC antennas and buzzer in place and held them in with some hot glue.
