There's a bit of a learning curve with the soldering and configuring when you're just starting but it's pretty worth it when it's all sorted out.
A learning curve? That I am sure of since the only FC boards that I know of are for quads. I have never considered using one for a plane and honestly, I didn't know it would work.

This plane (or the SSD version that sr71afan did that only seems to exist as a youtube video and some scattered pics) is one option I'm considering for a targeted build.

Need something that I can throw together super fast from the motor bins, spare servo pile, and acres of foam I have laying about. Slow, very controllable in a good sized backyard lined with trees, and able to take some paintball abuse with instantly folding. Looking at this, the SSD, some prop in slot types that have a shrouded prop or vertical fins that hide the guts a bit.

Thoughts?

Here's a F-117 inspired version of the SSD. Posted earlier in this thread.

A few more details here:

My variation uses a carbon triangle for exoskeleton and then $TF for a lighter version, or Elmer's foam for a stronger version as fill. And external elevons. Slick fliers and highly wind capable. The carbon is square outside, round ID from ebay-usa. 4mm for the lighter version, 5mm for the heavier.

For slow flight , low wing loading is the main ingredient ( maximum wing area combined with minimum weight ) .

For taking abuse , make it out of coroplast ..... but coroplast is significantly heavier than dollar tree foam board .

Should have said without instantly folding. Doesn't have to be bulletproof just not shatter instantly. So I'm looking at fast ways to armor portions without accepting total weight penalty. Such as using doculam or clear shelf paper on the outside of those big vertical fins on sr71's super slow delta, that would spread impact some. and those fins protect the prop and motor a bit.

Maybe buy a sheet of Dollar Tree and Elmer's foam, prop them up and shoot at them as targets. You should get a feel for how robust you want to build the plane.

Gary sr71afan showed dimensions on one of his videos , here's screenshots from that video :

Those pictures look like they were smuggled out of East Berlin by a Cold War double agent.

Going to shoot them with paintballs? Strip the paper off the foam board, then use extra long bbq skewers for spars to get back some rigidity. Paintballs will go right through the foam leaving a round hole and not tearing the rest of the wing to shreds.

I have printouts of those pics, they feel like contraband

I'm a little limited in testing, I don't own paintball stuff myself. Making the plane swiss cheese survivable is also an option. Dunno but it'll be fun to screw around with

Most prop in slot birds are pretty quick, or I'd be looking at one of them that has a belly plate on the bottom which helps mask the prop from paintballs.
