Im using the brushed electric motor that was already inside unfortunately I have no idea what it is. I hope to have it on the water this weekend to trial.
Basic set up one brushed electric motor powered by a 7.2v 4500 Nimh battery driving a 45mm twin bladed prop. Im using an old school mechanical speed controller as it was lying around as these things do. My only worry is the coupling which looks a bit weak to me. Im sure after this weekend the setup will probably change but thats half the fun 😀

Mate , lovely to hear , I felt a bit poorly somewhat going at you as over the top, which was unwarranted. I ran my vessel the last two weekends with my mates at the Lake Illawarra channel ( see google maps?) South of Wollongong New South Wales Australia. Well we are just a bunch of old boaties , sick of clubs and fights and restrictions/ rules/ flat earthers. We have a lot of public look at us and the Council Ranger and staff lookeee see at times , but AS we are in zone of the Lake Channel HiGH/ LOW tidal mark any authorities do not want to know us. Here in OZ you can still boat as we have a lack of ponds in the land (not like your WW2 type ponds built in villages for water for vehicle fire tenders from FIRE and bombing raids). We have extensions on household insurance in OZ to cover liability and we tell any noisy race/race boat types to ".... off". We sail 1 meters etc thames barge, steam and electric and i/c and all big stuff we ALL run together on the water on the "pond", old sets 27 40 and 2.4 gig. And I spelt Peter Dimberline incorrectly with a T , so he will find out and knuckle me!! I do clean the engine bay with motor car degreaser spray and the decks cabin etc with household Kitchen cleaner and paper wipes. Such is good old Dulux house paint over the years. Fold down f'wrd mast , crane sits in a brass tube at the port engine bay ,rear mast sits on a peg at stern, rear stbd hatch opens, ALL to avoid knocks breakages of bits and over the years I have actually cast alloy bits in plaster-moulds and screwed down with brass. Just a standard red plastic graupner 40 mm prop (4mm thread?) this motor is a SC china copy ? of a OS40 I think , I just run her at the first plane to look nice, no rev head stuff as not necessary, wide turns, but goes so well in 2 inch to 4 inch chop no pounding/ bone shaking during winter runs as it HAS to perform SCALE on the pond rather than toy boat behaviour such as dig in and flick turns and she is heavy to handle waves! Just standard home made fuel 4 to 1 and my mates talked me out of Castor, so now I use synthetic lube . We share all things. Too much talkie . All the best and just fly out to join us good weather too .

Hi Lyle:

Very good point about your model performing to scale with wide turns and just rising up on the plane as it looks far more realistic .
