Actually, its a little Kitfox and it has some really cool features. Next week, we want to test the third prototype.
from foamboard to 3D print EDF Jet!

Yowzah. That looks brilliant! My foam build progressing. Wings needed a few mm trimmed off the root to fit neatly, but again not difficult. I've made one modification - I'm putting the aileron control linkages on the upper surface to stop them getting knocked on landing. I'll glue the wings in tomorrow - it's a quick build!

Wings glued in and intakes done (slightly modified for no good reason whatsoever!). Currently a smidge under 500g with a 1400mAh 3s. Seems like it should slow down nicely at that weight as long as I don't add too much more weight finishing it?

Getting close. Just about to glue the tail on, but of course propped up the pieces for a photo!

Hey folks, would 6mm depron work on this build?

Yeah it should. Since foam board is 5mm you may have to make holes a tiny bit bigger

Thanks Griz and thanks to Dr Loop for putting in so much work and posting this.

Yes, but since Depron is not as stiff, put some carbon reinforcement in the tail. And you have to make the spar two millimeters thinner.

thank you wanted the plans right after seeing

I started again from scratch with the 3D printed version to get all the details right. Im now halfway done with it. I completely redid all control surfaces and the airflow around the EDF. It will fit the Powerfun 64mm EDF and the FMS 64mm EDF, and both are on the way to me. Because of my final exams and some other stuff, Im aiming to release it in one month. Unfortunately, the first prototype warped in my car in the sun. Be careful if you print a plane out of black PLA.

It's dopey question Tuesday so...I know how to stick build using plans but I've never actually built a flat foam plane from plans. How is it done? Do you lay the plans on the foam and cut through the paper plans?
Also, what size paper is this printed on?

My favorite method is to use spray adhesive to stick the paper templates to the foamboard. That way you don't have to worry about the templates shifting like they would if you were using tape to hold them on.

I use tape to hold the plans on the foamboard. Then I use a needle to poke holes wherever lines are. Then I can remove the plans and connect the dots with a pencil. This way, I can reuse the plans and I don't mess up the foamboard.
The plans are full size, but you can make your printer slice it into perfectly fitting slices. I think it's called poster mode.

Still haven't done maiden on my V1. Struggling to fix an electrical fault on ailerons. Hope I may get time this weekend!

The last part is printing right now! Its very close to release.

All parts are printed, the next step is to make the build video. If everything goes as planned, it will be available next week.
One thing I'm still struggling with is to think of a proper name for the jet.
Any Ideas?
