Hi Claudiu. I have the Zvevda kit of the PS SIRIUS which though quite an old moulding is still a pretty good kit. I got it to motorise and due to its deep and beamy hull is very suitable for RC., as long as batteries etc. are kept low in the hull.The paddle wheels are quite big and should propel it well. Save weight wherever possible so there is plenty of scope for additional ballast to counteract the tall sail rig. It will need the rudder doubling in size to have any effect. I would say go for it. Regards, walter.
