Encouraged by experiences gained from so far from approx. 50 flights with “Signorina Elettra”, I have now converted an IC airplane into an electric stunter. The conversion was fairly easy to do and took less than 4 weeks time. Originally, PC-21/2 (another of my Trivial Pursuit Special Edition derivates) was equipped with a PA .75 on pipe and at 62.8 oz it was not really heavy. However, adding ¾ of its 210 cc fuel capacity brought the mid-pattern flying weight up to 67.5 oz.
Here is the current data for the e-converted version of PC-21/2:
