We are finishing up the complete restoration of our 1952 L-18C and and I am looking for ideas on the best radio/intercom to install. It has no electrical so we are considering a wind generator to keep the battery charged. My mechanic recommended the Flightline FL760 and said he could install it in the wing root. Anybody else without electrical systems have any ideas or any pictures of their set up? Is a wind generator worth it? Thanks for the info.
