Cheap and Easy Prop Box

Prop Box

Prop Box

We are starting to invest in bigger and more expensive props for our gas powered model boats. Until today they were being stored in a cheap and nasty lunch box. Finally we pulled the finger out and used some common sense to build a cheap and easy prop box to protect our investment.  All of the parts used should be easily available from your local hardware store.

A simple and effective case that you can lug around to your local boating spot.  Not bad for the same price as a case of beer! Click on more below to see the full photo tutorial.

How to replace a Walbro carburettor shaft

Torpedo Stainless Carb Shaft

Torpedo Stainless Carb Shaft

Today we are going to install a Torpedo Stainless Steel shaft into our Walbro 1048 carburettor.

The Torpedo Stainless Steel throttle shafts replace the factory brass shaft in the Walbro carburettor that is prone to breaking. The Torpedo shafts feature a precision cut out on the opposite side of the butterfly disc to allow more flow through your carburettor. To assist in securing your throttle arm, both ends of the shaft are threaded to fit a M3 bolt. No longer will you need to rely on a tiny grub screw to secure your throttle arm.

Fuel IV Bag System

Fuel Bag System

Here at RCBoatBuilder we are split down the middle on two different methods of fuelling our modified Zenoah engines in our RC boats.  Daniel uses modified nitro gas tanks to store the fuel in his hulls and Aaron uses modified medical grade intravenous bags.

Today’s how-to guide covers the intravenous (baxter) bag option.  IV bags, fuel bags, fuel cells, gas bags and fuel bladders; are a group of commonly used names for polypropylene bags that can store fuel in RC boats. For the purpose of this article we will refer to them as a fuel bag.

One of the primary benefits of running a fuel bag setup is that it creates a closed fuel system. Standard vented gas tanks are susceptible to inhaling water in the unfortunate event of you flipping or sinking your RC boat.

HobbyKing Genesis

The Genesis catamaran is a very popular RC boat here in Australia.  Built by TFL Hobby and retailed by HobbyKing, it represents good value for money at $300 AUD.

Typically sold ‘Almost Ready to Run’ (ARTR) you will almost certainly need to add your own Electronic Speed Controller (ESC), Servo and Lithium Polymer (Lipo) batteries.
