SOY Electric RC by Brodak
The Spirit of Yesteryear kits typically show installation of a brushed motor with a gearbox and NiCad batteries. If you are going to use modern Outrunners with LiPo batteries then you will have to engineer a firewall mount and a battery installation. The good news is that the modern electric installation will likely be lighter and smaller than the old style components. Of course the kits can also be modified by the builder to accept IC engines of the appropriate SAM engine class – with the installation up to the builder.
