Is there any changes from the v2 to the newest batch? I get mine anyday. Any tips I should know?

The only change is the color scheme. With that said I might suggest you reinforce the internal landing gear block and or read the Etude mod I did or the Caelus build.
if you're running a Himax motor bye the firewall from Mike, it will save you hours of fab time. Also, the Gator battery tray works much better and gives the opportunity to get the CG right. This IS the last step you perform before flying.

I got the firewall coming . Have a gator tray from another project I might use. I see allot of you bringing your batteries way back to get ch right. What is a good starting cg, so I don't have to move my battery tray once installed. Can't wait.

I ended up at the rear edge of the wing tube.

I would highly recommend you add a carbon fiber rod to the interior of the fuselage,past the vent holes. The you see here was the last one I did for a friend. The plane was transported to Syracuse NY this past summer and from 1" behind the carbon rod to 12" back, the fuselage was badly damaged and now requires me to repair it. It's pretty fragile and the carbon rod weighs nothing.

If you look at the where the battery tray is placed in the fuselage, with Thunder Power 5S, 4400 pack the plane balances with the batteries in the middle of the tray.

Got the plane last nite . Overall not bad for the money. Hinges don't line up. And Axles have almost no threads in them so I got some dubros axles . The hinges are about a half hole off and drilled crocked. I spent some time and got them straighter . A former and one Rib need reglued. I'll post back once I get farther .It'll be a show build for me

Almost done with the build. Waiting on new turn buckles as the stock ones had to much chrome on them so the threads were filled. With mini servos in the tail, a heavier motor then it calls for, and 12s 5000 packs I'm still slightly tail heavy. I hope it flys better then it builds

Pulled the CG back to 225mm. Flys very neutral and crisp now. Time to hang it up for the winter
