I finally managed to maiden my new Viperjet today, after spending far too long completing the installation. However, it was well worth the wait, as the plane flew beautifully. I have followed much of the advice found within this thread and used JetLegend smoke tanks and a single front tank to help reduce the C of G shift through the flight. The power comes from a Jets Munt M100XBL and after 7 minutes the rear tanks were just about empty and the front tank completely full. Servos are Savox 1256TG with a Hitec 645 for the nose wheel steering.
This is the second one in our club and based on the comments this afternoon, there may soon be one or two more! Many thanks to Jeff Sewell at Zedjet for the excellent support and service.
