which is easier to build from scratch a electric or gas RC helicopter?
and why?
electric.
its been a long time since you can have free access to a metal working machine shop at the local factory for a few dimes a day or have a home metal machine shop in the garage/studio. even just buying a metal working lathe to build the gas engine block is prohibitively expensive.
