i have contacted spinmasters about the props in the past. they basically said since the AeroAce is still pretty new, they havent gotten to it yet, but there will be replacement parts, including props, available. i sent them an email last night to get an ETA on them, so i should hear back later today. you can try using Estes Aero-X props, but you'll have to rewire one of the motors so it runs in the opposite direction because they're not counter rotating like the AeroAce's.

as for antenna wire, if you have an old timer, or an old clock, take it apart and use the wire that is in the coil. or, just find the smallest gage wire you can and use it. it doesnt have to be anything special really.
