Yip. It makes a very good electric conversion. Mine had a 650KV motor on 5 cell lipo, which was way overkill.
4 Cell Lipo will do nicely. I removed the top fuselage between the canopy and firewall and made this a battery hatch.
The motor and battery need to be moved as far forward as possible. I later moved my firewall further forward as well.
The Travel Air is a nice 'floater', and on a good, hot day, I could stop the propeller and thermal with the birds.
Mine has since been converted back to IC and is my 'go to, i don't want to battle today' plane...
