My son and I built the 60 size delux version, the weigh of the gear made it a dog compaired to the stock fixed gear.
You might be able to get by with some of the newer lighter electric retracts and not lose too much perfomance
Hello MajorTomski.
If we consider that most think of "performance" as speed and fast vertical climbs it become just a matter of lots of power/prop combination and any extra weight of retracts becomes irrelevant.
