Another irritant: It has actual landing lights, but the manual mentions them only in connection with gluing the lenses on them. The wires are brought out at the wing root as raw wire ends, with no thought as to getting power to them...but the parts bag contains a simple plastic battery box meant to hold two AA's. I think I'll leave them inert for now and consider wiring them to a receiver channel later.
I'm following your example and ordering a Bisson muffler...that EVO muffler they recommend is downright Brobdingnagian.
