Gizmo (GZR) Billet Bottom End Kit

Gizmo Billet Crank Case

We managed to get our hands on the latest release of the Gizmo GZR Billet bottom end kit. This is the second generation of water cooled Billet crank cases from Gizmo, following its predecessor being taken from the market back in 2015.

Moving on from the bearing issues with the first generation, Gizmo have openly boasted that V2 is the most diversified Billet crankcase on the market today. Capable of housing any marine style coil and the versatility to support most cranks on the market including the Zenoah tapered cranks.

Shake down – MCM 46″ Catamaran

Quite a few of the boys headed down to the flooded Hawkesbury river this morning for a run (we are not scared), unfortunately our footage was average at best (blame Aaron). However here is a quick video of the new MCM 46″ Cat shaking down a fresh 29.5cc motor.

Will most likely pull out this 29.5cc motor and swap it for a fresh 30.5cc in the coming days. The video shows a very mild tune on the needles. However keep posted, fairly confident you will see these hulls hauling ass in the coming weeks!

F1 Tunnel Hull (Gas Outboard)

F1 Tunnel Hull

It’s been sometime since we have actively posted on the website, between laying up hulls and spending some serious time out at the lake. It’s been a struggle to keep the website updated, however we are always posting on our Facebook page (smart phones make life easier).  You can visit the page even if you are not a Facebook member by clicking on this link. We also continue to post videos just about every weekend, you can view them on our YouTube page by clicking here.

As some of the regulars may be aware, we have acquired quite a few interesting moulds this summer and have begun pulling them out both professionally and in the RCBoatBuilder sheds.  One of the more exciting moulds is the quarter scale F1 Tunnel hulls, with two different deck designs.  Over the past month or so, we have assembled both of the designs. One with an inboard gas motor and the other with an outboard gas leg.

While we continue to fine tune both hulls before posting any video, you can view the photo’s from the

build logs in our photo section.

45″ Typhoon ‘Super Big’ Mono

Recently we have been supplied with a bunch of hulls from Typhoon.  A brand of model power rc boat hulls and hardware from Thailand, very popular in South East Asia.  These hulls are sharp and designed for fast point to point racing. Here is a quick video of Dan from RC Boat Builder running the ‘Super Big’ mono powered by a Torpedo Zenoah engine.

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.

Swordfish Pro + 300amp ‘Lite’ Edition

12046738_1030090567022188_7923350177028982814_nIt wasn’t all that long ago that we reviewed the Swordfish Pro + 300amp electronic speed controller.

In short; we named it the best value high voltage speed controller on the market. Packing features like an operational range from 2-15s with data logging and programming capabilities.  Now just six months later we have been advised by our friends over at RC Boat Bitz that they have stock of the new ‘lite’ edition!

Packing all of the same specifications of it’s chunkier and heavier big sister, the new slim downed version is lighter and cheaper!

40″ Mono – Modified Zenoah G300

We went for a short run this morning, here is a video of the Thurgarcraft 40″ powered by a modified Zenoah G300. Second run, still allot of dialling in to go, but it’s coming along really nice.

You can find all of the photos taken during the build process of this boat here.
