Matt - I have one, nearly finished , ready to fly , with RCFG 20cc engine...yes it has retracts - they are a bit troublesome to set up - but I have sorted them ..already burnt out one wing RT servo on them .
Nice model , well made , mine will be a bit over 12lbs RTF ....came out very nose heavy . Batts have to go in the rear ( compartment is provided ) but will still need lead in the back
