Maybe Martin Weberschock has the most original offer for "f3b buyers". The way he manages his Europhia's master forms is not very common. You can rent the master forms to make your own molds. Martin makes seminars to explain how to make your own Europhia with special prices for young people. Firms like Tun Modellbau or StratAir commercialize an Europhia not made by MW taking adventage of this system. Everything is made to make f3b more accesible for everybody. Bravo Martin! Here a report from RC-Network Modellbau Magazin about Martin and his seminars (in german)
