In that case,Josse, will you listen to what is said and put to you.
First of all, you state that( on another build log of yours) you are a student of model boat building if my memory serves me correctly.
Is this a student from college or a self taught student?
If from college..ask for help, in building and finishing techniques for a start.
forget the electronics until you have mastered the technique of basic building and finishing a model to a decent standard.
If there is a model club near your home, go to it and ask how those members finish their models.
Concentrate on one model at a time, not 2, 3 or even 4 as you are building.
Start small so that the project doesn't overwhelm you, as they seam to be doing at the moment, and above all TAKE YOUR TIME, and don't rush a job just so that you can "please" others by constantly blogging........no one is really and honestly interested in quantity, but they are in quality.
I hope you take this as constructive critisism, and not just a dig at your skills.
I used to teach model boat building at "night" school and as you seem to be wanting to do, so some of my students wanted to go home with a finished model after the first night.
It just isn't possible, and you will get a greater amount of pleasure from your modelling, if you SLOW DOWN and take care and time over a build.
all the best and take care, but above all, take some pride in your workmanship.
