    klotz oil

    Klotz has cut back on the information they used to have on their website. They no longer list KL 200 techniplate (pure synthetic) but you can probably get it if you phone in an order. Klotz used to have the technical specs on their website which provided all the good information on their...

    Fuel mixing

    One of our guys tried Nitrobenzene once. Had to use gloves and a resperator as it absorbs through the skin on contact and the fumes are volitile and carcongenic. Why shorten your life for a few extra rpm. Proplyene oxide is a good additive but it's got a low boiling point and will only...

    Thanks Ray for finding my picture. I was able to get it on to my gallery but I was not sure if anyone could see it.

    Insurance coverage racing in Europe? Does IMPBA or NAMBA cover you?

    Look into and Umbrella policy. I have one and it covers any occurance be it car, house or me driving a model boat. They don't cost much. It essentially doubles my car insurance for less than a quarter of increasing the specific car insurance by the same amount. For Europe, we signed up...

    Noise suppression

    I have tried to past a picture of my latest muffler but I can't seem to get past some security issues. My latest version is made of PVC electrical conduit. The original was made from 6061 which seemed to add a high pitch ring to the sound. Most pipes are made of soft aluminum which does not...

    Noise suppression

    I think my exhaust is adequate. I've built two exhaust cans, one looking like a standard available aftermarket (on the end of an AA 45 muffled pipe) and a bigger/longer one (about 5 inches by 1.25 inch) made from plastic conduit (to reduce radiated noise). As I said in my original missive...

    Noise suppression

    I am heading to Haarlem in the Netherlands for the IMBRA race in August. I have been working on new muffling but am having trouble getting the db under 82. The exhaust is quiet on the bench so the intake is beginning to dominate the sound level. My meter shows a drop of 4 db between the...

    Digital Servo high current draw

    Ok. I didn't know that link. The servos are not Futaba, just the transmitter and the receiver. I was concerned there could be a conflict between the Futaba equipment and the non-Futaba servos. Sounds like I am not experiencing something that is totally out of the ordinary.

    Digital Servo high current draw

    Alan, don't know where you got your information but this has nothing to do with Grim's products. I have unplugged both small servos one at a time and it's definitely confined to these ones. They both behave the same. I am using some 1000 ma AAA NiMh battery packs that I put together. I'm...

    Digital Servo high current draw

    Just working on a new boat and have digital servos installed. Two of the three seem to whine a lot and it seems to be due to the slight pressure my seal exerts on the control which keeps a small amount of pressure on the servo. This is causing the servo to try to maintain position and to...

    Russian K Motors

    I had some new pistons built for my K-82. I ruined a number of sleeves due to the wrist pins breaking but I think the problem has been solved by using Rossi wristpins. The sleeves I have left are not 100% good but good enough to maybe re-use. Most of he damage is below the ports. I have...

    WTB: Mutt sport 40 cowl

    I am truely sorry for that. Maybe I should have aimed for it and then I would have missed it. All I remember was my boat flying way down in the corner. It was amazing the CF booms held up under a direct hit at 50 mph. That Aluminum exhaust stack just crumpled like a beer can and absorbed...
