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...

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.

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...

Add on mufflers to meet IMBRA 80 db.

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...

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...

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...

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.

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...

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...

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...

I have a movie of the Nitro Final. Here is the link to my Skydrive storage site. I hope it works as I am new at this movie posting. https://skydrive.live.com/redir?resid=520AEB271C676C7E!115&authkey=!AGYvKE-LludPjOk Also, here is the 1/7th electric scale final. If you have never seen...

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...

The picture with the ruler shows the bottom of the strut is just about parallel with the bottom of the boat. It looks like it has up angle but that's an optical illusion. The transom is angled back by 3 to 5 degrees (not perpendicular to the keel), probably so the boat comes out of the mold...

I finally got some pictures. The strut definitely tilts down to the water line and water off the keel could be pushing the back end up. Two fixes, move the strut up or put a wedge between the strut and the hull to tilt it up. The latter will save me having to drill new holes. I tried to...

I put together a .21 Seaducer SD3 this summer but I'm have a big problem getting it un-stuck from the water. I know the built in hook in the bottom is designed to keep the hull in the water but what I have is way too far stuck. The hull contacts the water hard from about 4 inches back from...
