1) Too many integrator blocks
2) Try rearranging the blocks concerning the electrical and rotational domain so you can easily follow the model flow from left to right
3) Rearrange the electrical equation to the find L.di/dt
4) Rearrange rotational equation to the find alpha
Completed the M&S challenge now with this final problem but no badges/points update :-( This was going to nudge me into the top spot of my work Cody leaderboard!
