Anybody else scratch building tonight?

I’ll grab what I have for the plans and sketchup file and post tonight if I can get to it. The flattening of objects in sketchup worked well for some components, but not all. The wing shape was perfect and I custom built spars after I shaped them like Flitetest master series wings. I added circular formers into the wing structure then skinned it. The actual build was similar to the mockup but I had to custom fabricate a few pieces such as the canopy. The entire nose section was removable and the battery and ESC sat below the wing which was accessed with the nose removed. Lessons leaned. I used too many formers. The skin adds plenty of structural support. I only used elevons and should have added ailerons. I should have increased the diameter to allow a bit more air flow.

I’m going to take my lessons learned and build an F-86 instead. The shape of the fuselage and wing position will be a better fit for the build design.

The fan sits at the intersection of the wing trailing edge about 20" from the nose of the aircraft. It's almost the identical distance from the outlet. I used tagboard for a thrust tube. The entire nose section is removable and is held in place by a couple of foam posts the fit into slots in the nose section rear former. The battery sits on the bottom and slides into a hole in the bottom of the formers and then the nose slides over the battery.

I built mine and it is really underpowwered on the 4s htat was recommended on mine.
I was planning on using a 6s 5000Mah 50C battery. Just a question of which brands are solid and hold up to the advertised spec. I've noticed a lot of brands and a lot of complaints about them. I haven't been in the electric side of the hobby for very long (old school gas and nitro guy) so its been a lot of hunting and poking for reviews and info.

VALUE HOBBY batts and edfs seem to be very popular and trusted for a cheap price

RCBattery.com is a good source. Pricing is pretty good and shipping is fast.

Had a successful maiden of a scratch built 64mm EDF design yesterday. It’s made from 6mm insulation foam (a bit like depron) because I can’t find flitetest foamboard in the UK at the moment. It was a fairly simple build and flew well from the off. Just need to add finish a few details and add some colour - it’s very hard to see against a white cloudy October sky!
