Blu-BC12D - Taylorcraft BC12D 48"


Just started drawing the plans for this one. I wanted a 48" WS plane that was something other than the venerable Piper Cub. So I chose it's competition...

The Taylorcraft BC12D

Admittedly, I don't know much about Taylorcraft and the model variants, I just liked the lines and the rear side window on this version.

As with DHC-2 Beaver and Blu-Citabria, this design is based off the Blu-Baby series with monoblock construction and KFM wing. This will be a 4 channel plane, but it could easily be modified to 3 channel.

Here is the latest 3 view drawing. I am still fine tuning the design. Once I get the beta build done and work out the bugs, I will post the full plans.

Comments and suggestions are welcome!

Enjoy!

Looks interesting. As a new builder would I be better off with something like this or should I go with the original Blu-Baby first?

Although this plane shouldn't be any more difficult than a Blu-Baby, I recommend building one of those first. It will teach you the construction techniques needed. Plus, it's a proven design that flies well. The BB33 is my all time favorite.

Thanks for the info. I'll start with a BB33 and then give this one a go.

I would rather finish my beta build first before posting the plans. Stay tuned.

Philipa,
The plane looks like it will be a nice model for a 4channel flyer. Keep us posted on the build.

I've started the Beta build. A few things I noticed:

1) The wing saddle appears 1/4" too narrow.

2) The dovetail located on the LE of the H-Stab does not fit into the fuse as tight as I would like. I need to tweak the plans a bit. I originally came up with this design on the Blu-Citabria as it helps to locate the H-stab properly on the fuse.

3) The wing attachment method is not shown on the plans. You could use dowels and rubber bands, wing bolts, etc.

4) I do not show a method of joining the elevator halves. You have to be creative here like I did on the Blu-Citabria build. A piece of flat CF, thin ply or balsa is used to join the halves, then you just need to notch the fuse a bit to allow for down elevator movement. See attached photo:

Beta Build completed. I still have to mount the motor, esc, etc. Crossing my fingers that the CG will be spot on without adding ballast.

I love building these foamies. I knock one off in a weekend and it's instant satisfaction!
