    OUCH!

    Now if you had been running one of our New Zealand made bullet proof fail-safes in your boat I bet you would not be faced with the repair you have. They are compulsory in our country if you want insurance cover whilst running under the auspices of the New Zealand Model Powerboat Association...

    Who's got the nice Modified Zenoahs?

    I run an Omen 23 in my backlash here in New Zealand and it more than has the measure of any other 27 than anyone runs out here.

    Props

    I got a couple of counter rotating 3d printed stainless V947/3 props for my Keith Bradley Fighter Cat on 12S a couple of years ago and the finish superb and balanced perfectly on my balancer. They got me close to 100mph at 158kmh. January this year I set the Australasian 12s Tunnel record here...

    Question about rudder placement, Sport-40

    Brandon/John. I have copied the section out of Les's book for you. Bear in mind this was written way back when radio gear was not as good as it is now a days as our gear has a lot more grunt than back then but that pivot angle is still important to consider. He talks about the rudder on the...

    Question about rudder placement, Sport-40

    I have always used the Les Ruggles principle of a rudder pivot angle of 17 to 18 degrees on all my hydros ever since I read his book on setting up scale unlimited hydros way back in 1982. He must have known his stuff because if I get in that range my boats turn with out effort and seem to go...

    Need info for Zenoah 23cc carb

    Larry I am running a CCRacing modded 1048 carb on my Omen mod 23 Zenoah out here in New Zealand. That thing in my Gen3 Backlash even keeps the big blocks honest on the oval course here. Just another option for you

    GPS options (waterproof or not)

    I use the skyrc GSM10 in a custom perspex box to keep it dry. I use hockey tape over the holes to access the various buttons and works fine. A piece of thin Blue foam on one side gives added flotation if it flies of my boat when I flip it. I can't seem to attach a photo of it for some reason...

    best fuel option for my gas boat?

    That graph tells it all for me Lohring. Why piss around with additives etc when the good ol 87 is equal to if not better than nitro and bang for your buck cheaper as well we have to run 91 coz that's the lowest octane you can buy at the pump in NZ regards Grahame

    Engine Failure

    A big thanks to Bruce and the boys at Gizmo for the work on my engine. The jug came back like new together with a new crank/rod plus piston, wrist pin, ring and bearings. Ran it in last weekend and the backlash is boogying again. 19500rpm on both a gizmo 7016 in our small club pond and a COCR...

    36" Sprint Cat SAW

    Logics tells me altitude on its own should not have any effect on the COG of your hull wether it is running at sea level or 5600 ft. What altitude will affect is the tuning of your engine. The air is thinner up there so your engine will run richer than at sea level Contact the hull...
