Hi all, I have a question too about fuel pressuring. I bought a used offshore mono-hull boat from a guy, but he hadn't pressurised the fuel tank at all. I am thinking about drilling a hole in the pipe and putting a nipple there, and then pressurise the tank from there. But if I start drilling...

Thanks both for your replies. Hmm... Maybe a hotter plug could be worth a try, I actually never thought of that :P When I buy plugs, I usally just buy what is recommended for 25% nitro which is medium-cold or something like that. I am not experimenting with plugs very often, mostly I just...

Ok, here is a problem I usally have on all my nitro-racing engines (boats & cars). When I'm tuning in the needles, I usally set the high-speed needle first. It may take a few testruns to find the best setting, but no problems so far. Then it's time for the idle-needle. I usally make sure to...

Hello you all! I'm about to buy a new radio to use with all my boats and other 2ch models. The radio I have in mind is the Futaba 3GR-FS/FM. This radio model seems to offer all the necessary programming possibilities that I need on a 2ch/3ch radio, and at a reasonable price. In the hobby...

Thanks Jerry, I also read on another forum that you are using the Silver Bullit HP. Aren't you using an OS on your TS2? Where did you find the header you are using?

I want my TS2 to go faster. How much would a pipe make a difference in speed for the OS engine? Is there any pipe in particular that anyone would like to recommend for the OS? And are there pipes I should stay away from?

?? An electric powered Top Speed 2 ?!? :blink: What kind of motor do you think he have mounted on it?

By the way, I find the info on the prop-cutting site a little hard to interpret, the pics are not real photos but just hand-drawn sketches. Anyone who would like to post a pic of a 1440 backcut for the TS2? Any other backcut prop would also work, just so I get the idea, but it's the 1440 I'm...

Cool. Did you install the recovery pads on it? 120g right in front of the fuel tank, will that take away some of the bouncing? I will try your setup the next time out and see if it also works on my TS2. I don't have the 40x53 prop, but it's worth a shot anyway. Pulsetech, thanks for the link.

I had a run today with my TS2. Experimented with the nose weight and engine thrust/prop height. Still could not get rid of the bouncing at low to mid speeds. Some settings were slightly better but not much. As soon as the speed got up to the point where the lift is mostly aerodynamic it went...

The engine should be broken in now. I have run the boat for 7-8 tanks. I reduced the water cooling from tank 3 and up, and when I gradually leaned the engine after each tank I gradually also increased the water going through the cooling head to compensate for the leaner nedle setting. And...

The carb was never more than 1/4 open when starting it and running it on shore. So I guess I shouldn't be worried about that then. When I bring my in I can keep my fingers on it for an unlimited amount of time, it's warm but not warm enough for me to have to remove my fingers after a few secs...

I'm not very satisfied with the first testruns. The boat was bouncing a lot on low to mid speeds, but there was no bouncing on higher speed (which I could only notice when the fuel was getting low since I was running rich). I was using the prop coming with the O.S. engine. I tried the 1440...

Thanks Piper and Topfuel. Together with yours and all other peoples advice, I've got a pretty good idea of how to break in my engine now. Today I went to the hobbyshop and finally got a working hi-torque steering servo, and at the same time I returned the other one that was incompatible with my...

JD, Don't worry, the lakes won't freeze to ice until around the middle of november, so I have plenty of time :lol: Topfuel, Thanks for the reply. Very interesting and useful info, just the answer I was looking for. :) I will take what you have said into consideration when breaking-in my...

I was just curious why James is using such a high percentage of nitro even while breaking in, so I asked him about it. I didn't mean to imply anything special by that, and I'm sorry if you misunderstood me. I am asking people things so that I can learn, not because I want to tell them what to...

How come you break in your engines with such a high percentage of nitro? Everyone knows that very high percentage of nitro shortens the life of your engine. Personally, I would never use more than 25% nitro if I'm not participating in a competion race. And this is especially while breaking in...

Ok, thanks JD. What have you guys done to make sure the engine won't sink to the bottom of the lake in the unlucky event it was to fall off the transom during a run? Have you used a fishing line or something similar to that? What places on the engine and the boat have you used to secure this...

Yeah, I can see you're right about that when taking a look at the water cooling pickup. I may not experiment with the water cooling after all... Is the hole in this pickup of different size on the different brands of engines, or is it exactly the same size on K&B and TT engines as on the OS?

I did exactly the same thing! Yesterday, after drilling the holes for the original threaded inserts, the tabs broke off when I was to screw them into the transom. I've read earlier in this thread that others had the same problem too, so I wasn't very surprised when it happened... <_< By the...
