A few more cosmetic bits done now. Still awaiting the RC helicopter arriving for the helipad and awaiting new filament to print the spinning radar. Have an extra water pump onboard now so that's 4 speed controllers now along with 3 batteries. In yesterday's bath test at 5% throttle which gives a slow Ish cruise speed she sat running for 5 hours and 15min and I had 22% left until low voltage cut off out of the twin 3s 5200mah 80c lipo batteries and both motors where Luke warm
Gyro has been adjusted again on the stabiliser fin so the next non gale force wind day will get back to the river for more sea trial's.

More progress and getting closer to pond trials. Still aiming for this Sunday morning. Tomorrow the premium ballraced propshafts will be fitted along with her 5 bladed 40mm props. Some mixing to do in the bath tomorrow evening to get the steering and fwd/rwd finely tuned. The rest of the detailed painting will happen after the pond trials.
Battery arrived in the form of a 3s 5200mah 80c though the motors will be limited to 30% power available. Estimated constant run time of around 1 hour Rc helicopter has been ordered for the helipad

Hi Pete
Yes and very easily. The recommended build plate size would be 220mm and upwards. I've designed a couple of high pitch 3 blade propellers for her also that would be ample. They are 50mm and are left hand and right hand. I will be trying a 5 blade and 7 blade skewed propeller design too. I'm trying to get as much thrust from as low rpm as possible. These 3 blade propellers pull 14amp at a capped 50% throttle and in the bath on my test board they produce plenty of thrust. My scales reading is 700g of it Regards Scott

Cheers, Pete 😊 ▲

More sanding completed and some additional parts printed. Have decided to add further railings towards the stern area.
Now working on electronics for the spinning radar and moving spotlight, nav lights and spluttering exhaust cooling outlets

Hi its the Creality K2 Plus with 350mm x 350mm bed size and using PLA+. She's quite small in terms of what tou could print from that bed. Could easily use a smaller 220mm bed for this size.
Will be coated in Epoxy resin before a few layers of the gunmetal grey paint and lacquer. Also for the stl files. Once I've finalised a few errors in the print model I'll happily hand them out. The original real vessel is the Stan patrol vessel and it shares part of that design. Part of the bow is 1inch solid PLA for strength with a 2cm solid keel line as a backbone. I'm going to glass some internal joints for added peace of mind though the sections are coming together nicely. Heres a photo of the smaller accessories printer hard at work with guardrails, bollards, spot lights, rudders and A-frame

I’d that 3D printed? Where can I get files? Nice beginning. The stabilizer fins I like that. Had them on real Navy ship. It helped during a hurricane crossing the Atlantic. The one on left I had non working stab find. I have servos n could have made them like rudders or ailerons. I even have gyro board. Kick myself on not thinking of that.
