An itch?. Scratch build.

What has evolved since this thread started.

DAve.

I found this thread in the EDF Jet Talk forum -- Four Microfan Vulcan but it's 10 years old and not the kepa one.

Most of the Vulcan models tend to be pusher prop, (mine included), but you could try a search in the -- Foamies (Scratchbuilt)forum, you may find an EDF powered one or at least a model in the size you want easily converted to EDF.

EDFs tend to be very amp hungry, so many builders go for pusher prop, you can't really see the props when flying.

Edf Version


Thanks for the feedback. I've opted to go with a pusher but contemplating a slot in the rear third of the fuse to mount the motor further forward. I've already built the base layer from correx, and will add the kfoil and fuse from depron next.

Does anyone have advice, pics or a video of adding the top skin to the wing? Is it done in one piece or sections?

An update if anyone still looks at this thread. I covered the 6mm depronnwith packing tape and stuck it down with a 3 tube of contact adhesive equivilent to UHU POR and taped it down for a couple of hours. The result is almost 100% perfect with n gaps of cracking.

Here is a layout for a 2M Vulcan from the plans proffered in this thread.

I just traced the lines in CAD and scaled them to 2M.

Not built yet, still considering IF I want one this big or not.
This is just an offering for your consideration.

Lots of stiffening innovation would likely be required
or just build it LIGHT and fly it SLOWLY and Majestically.

It's all about that iconic silhouette in the air
scale speed will give it authenticity
nice project
maybe you could fit a tiny amp and speakers for the 'howl' on takeoff
