Looks cool. Plus it looks like you modified a slow stick 'frame' as the fuse.. Is the rest of it foam board?

Here see if this helps. Sorry for the water marking on the graphic but I've had some issues with Chinese kit makers stealing my plans and making a quick buck off of them. Some of the original idea came from my first FPV plane Aerosodle. Qrome had a good idea with his QTB plane over in the AP forum.

The front one has a slot for the boom to go into. You then bolt the boom into place on the front boom holder. The back boom holder just holds things in place. I guess I could draw out a more detailed boom holder if everyone was interested.

Looks good! You might want to put some plywood around where your booms attach for a bit of extra strength, if the wing doesnt have a lot of ply in there to start with.

is there any specific advantage in using twin booms? or is just to have some space for a push motor?

The motor is mounted very close to the CG. The prop is between the twin booms. It helps cut down on weight IMHO... If EDF was a bit more efficient I'd pick one up, mount the fan slightly behind the CG, and go with that.. I have a fan from an old EDF plane.. It's just finding the time to build out a new plane for the Fan! *The time!! The time!!*

It would be nice if there was a EDF BL outrunner(maybe there is ). I put my FPV gear in my Twister EDF and I loved the sound it makes through the headphones. Made it seem like I was really flying fast .
