Hi Brenner,
Some new competition in the contra market - not exactly a surprise !!

More a copy of/upgrade to the Seba approach, it would seem.
At €1290.00 ($1500.00), not including props, it is a little more expensive and without gearing or motor options.
I've posted here as it is now in the public domain anyway.
