1:30 scale fiberglass hull PT boat scratch build

[utmustang05]

Hi all thanks for letting me join.
I am going to finish a PT boat that my father started after he moved in with my wife and I. Unfortunately he passed away before getting very far on it and I would like to finish it in his honor. All I have is a completed fiberglass hull that is 30" long. I would like to put 3 motors in it and my biggest question right now is what RPM motors should i go with?

Sorry for your loss! I think this would be a great way to honor his memory. Looking forward to this build thread.

Oh, welcome to RCNT!

Wasn't the PT boats like a jet ski and they used jets instead of props?

Is this a kit? Or is it a scratch build?

pt where shaft driven props... 3 motor will be a challenge to get then to work like the pt's did.. rpm does that mean what we use as kv.rpms per volt.. your power supply batteries or battery will determine that.. a pic to prove my statement.

Sounds like a cool project. I won't be much use to you, but really looking forward to your progress. I think your Father would be pleased.

Not up on the military vessels much, but which one was it that was used in Vietnam that had the jets instead of props for running in the rivers over there? Jeremy Clarkson had one custom built to original specs in one of the Grand Tour episodes, and while the other guys were busy untangling fishing nets from their props, he was scooting through things just fine. Until he hit a patch of weeds anyway

The WWII patrol torpedo boats had 3 V12 Packard motors that drove 3 under hull props. You may be thinking of the river patrol boats of the Vietnam era, they did use jets. This is a scratch build. My father has made several scratch builds including a 1:24 sail boat and a river paddle boat. All he completed of the PT boat before passing was the hull in fiberglass.

Thank you and I will post progress.

Thank you for the info. What I meant to say is what rpm output of the motor. I understand it depends on the input voltage but what I am not sure of is whether I should use a high rpm output ie: 40000 to 50000 rpm or around 10000 rpm.

I don’t know what their official name was but Ih ave always known them by RiverPatrol Boat. If all goes well with this one I am thinking of building a river boat.
