Joining motor stick to boom...
I made a plug up from the motorstick wood.
This is an area that I learnt a lot.
I didn't make a very good job of it, especially as a removable joint.
So I glued it all solid.
The plane is small enough that I don't really need to break it down for storage.
I went wrong in a number of areas and would do things very differently the next time.
Essentially you make a sleeve that sits inside and the boom sits on one end and the stick on the other.
You fix the stick end. The boom end should be tapered so the boom will tighten up as it is slid on.
These suggestions might not be the 'correct' or best way of building, but it's what I'll do when I build the next one.
If there are people with more experience that can explain better processes then I'm all ears

The motorstick - I ended mine at the length of the motor hook.
I think that was a mistake, I see F1D planes and they extend past the motor hook.
By having the hook right at the end I needed to slot my plug sleeve, that caused an issue as it became less solid.
I also distorted my motor tube when inserting the rear hook web so it ended up as a 0 shape and not a nice circular O.
So the plug had to be shaped to fit.
I also used a rubber band to hold my tissue wrapped balsa together - that introduced surface effects that were not nice.
So the end of my motorstick was untidy.
The plug was then even worse because of slitting it to fit around the hook web.
Then distorting it to shape to fit the motor stick it went an even weirder shape!
Ideally the plug needs to be parallel bore a the stick end and tapered at the boom end.
Or, if the insertion distance at the stick is minimal, could be tapered all the way.
I broke the end off of my boom, so I couldn't really trim it to the right diameter to fit the plug, so it was a little loose.
I ended up gluing it all with some very thinned cement.
The motorstick is the area I am least happy with
I really should do it again

I'll take some photos of the area and photograph the next one I build.
Lessons learnt to integrate in the next assembly:
1 - extend the stick 10mm aft of the rear hook.
2 - use a jig to make sure the rear hook web is inserted and fixed without distorting the motor stick.
3 - wrap both boom and stick ends with a few wraps of Kevlar to hold that end joint closed.
4 - build a specific form for the plug shape including parallel section and tapered end.
5 - don't use anything to wrap the tube with when drying.
6 - be a lot more careful with the boom little end.
I have some more wood on the way, so I'll be having another go soon.
Best regards
