It feels like Multiplex manuals haven't moved on from say the 1970's. I spent ages figuring out the meaning of their wing pylons for strengthening the huge ailerons. Probably not the only 3D plane to use this technique, but Google didn't prove my friend for once.

Six carbon rods come in from different angles and should meet at a point. The manual just has an implied "cut rods and glue it"!

I'm vaguely wondering if some carbon cloth (finest DLG grade) over the join might give the join the strength it needs. There is no way I can achieve angles on all the cuts for a solid butt join.

This is my first build with predominently cyano, but I can't see how even gap filling cyano would be trustworthy here.

I link a shot of the rods loosely in position, with the four from the corners of the aileron not cut to length, so extending on upwards.

I'm sure someone on here has been through something like this before me...
