Graupner will recommend their own equipment, but other equipment should do just as well.

This site specialises in ship radio control electronics, and can certainly provide any control system you might want. **LINK**

Contact them on +44 (0)1248 719353 and explain what you are looking for. They are very friendly!

Yes, quite easily. You would only use the BEC from one ESC, and disable the other by taking out the +ve (red) wire from the receiver plug. Contact the link I gave you above – they will explain it all…

Before you use up cash on what you may not really need find out if you can get spare props as you will break them sooner or later they are probably still plastic as the other graupner models .If you can't you are looking at custom modified ones being made as they are not threaded. also she runs fast enough on 2 props

Yes once you have threaded shafts you are spoilt for choice on props the one on our lake is far too fast even on two motors to be honest its a bit on the small side he still has not got it ballasted right
