Hi JapanStar49,
I use these resources to learn how to write kanji/radicals:
1- Kanji Stroke Order: How to Guess it Every Time
Already posted, but this is a very good primer on kanji stroke order, which will teach some of the logic behind it and even let you guess the order of some kanji.
2- Jisho.org
Online dictionary with stroke order animations and diagrams. A very good and free reference.
3- Videos
In fully japanese, but just watch some of his videos and practice a little on random kanji and it will help you get a feel for it. He also has videos on writing with fudepen, ballpen and brush techniques.
4- Charts
Also in japanese. There are charts for kanji with stroke order, you can print and use them to practice.
For creating a SRS system to do that, I’ll refer you to this topic by Ncastaneda, which is the closest thing that I’ve came upon:
I hope this helps!
