The B60 marketed by Hobby People is the FLYFLY production. It has a full canopy to include the passenger section made of some type of thermoplastic, and has different electronics and motors. It is also available from AirShow...the link below has a lot more info than the Hobby People site.
The other B60 offering from NP and EasyTiger may or may not come out of the same factory. It appears to use the same molds.....maybe it's a copy of the FlyFly with some modifications, or it may be an earlier version of the product?? And, the current FlyFly model is the newest production from FlyFly
