I find Leviosa basically prepared for electric.
Even so I have built my second Leviosa powered by Mintor 1.70 since I lost control of my first one
(mentioned pages above) and badly crashed:

Tomorrow I am going to get the next one to assemble, and powered by YS 1.60. I will use hyde mount with nose ring.
I'll try to be quick, pic's in a week.
As you see I like this modell very much.
