Yes, you can convert the model to electric.
From Page 63, Sept, 2018.
That looks like an R/C version from a Spirit of Yesteryear (SOY) kit. He is using a Rimfire "400" brushless motor on
[email protected] mAh cell drawing about 130 watts. This will result in a ship that has about 3 times the performance of the Cox powered 1/2A Texaco.
For the SOY model Brodak recommends a much more economical set up. Still too powerful for FF in my opinion.
