RE: Slimline Still in Business?
They called me back a little while ago, and they are still in business. Unfortunately, they no longer make a muffler for my engine, a Brison 3.2. They said they quit making those 5 years ago.

RE: Slimline Still in Business?
Thanks W8YE. I tried calling them again at the number you posted 5 minutes ago. They didn't pick up the phone and I left them another message to call me back or e-mail me to confirm my order. It's looking more like they are out of business......or maybe their customer response is just really poor. I e-mailed them again last night, and received no response.

Slimline Still in Business?
Anyone here know if Slimline is still in business. I ordered a muffler ten days ago online, never received an order confirmation, left a message on their answering machine, sent an e-mail asking if they received my order. I received no response from them at all. If anyone has the scoop on them, I'd appreciate to know.

RE: No power for hovering in my ZDZ 100 ??
Adding the smoke fluid cools the pipes and changes the tuning effect of the pipes on exhaust scavenging. So, either you have to change header length, prop, needle setting on the carb, or get more airflow over the pipes to keep them cool without having to add smoke fluid.

RE: Beila prop performance on a DA100
The Biela 27x10 is pretty similar in load to a Menz-S 27x10. I have used both on my 3W-106. The flying characteristics are a little different, both fly the plane well. Either would be an excellent prop to use with a DA-100, expect ground rpm around 6300-6500.

RE: Anyone spinning a 23" prop on a Brison 3.2?
If you want to slow the plane down, use less throttle. I would pick a prop that spins in the range of 6900-7500 on the ground for best use of the engine's power. A Menz-S 22x8 or a Mejzlik 22x10 work very well for me on a 19 lb bipe.

RE: Brison 3.2 Prop Strike
Brison (when they were in business) recommended changing the rod needle bearings when you had a prop strike. Perhaps they felt the needle bearings were pretty marginal to begin with and couldn't stand the additional stress of a prop strike? You won't twist the crankshaft because it's one piece.

RE: Best 100c class engine?
In that size range, there are plenty to choose from. DA, BME, 3W, ZDZ, Kroma, Mintor 3M. Everyone seems to agree that DA as a company has a history of taking care of you best if something goes wrong with the motor - engine's fault or your screwup. I like the power of my 3W-106, it's a little stronger than the DA. The ZDZ is lighter, and the BME is the lightest - haven't seen any of the latest ones run. A friend has the Mintor 3M, looks beautiful, but don't know how it's going to run or how the company will deal with service - they say it has a lifetime warranty. Kroma, haven't seen one.

RE: 3W 80xi will not start
Plug gap for the CM6 plug is 0.015-0.018 inch. However, gapping it down to 0.012" takes less voltage to fire. So, if you have a weak ignition or a plug with some carbon deposits to leak the voltage away, the smaller gap will help it run.

RE: DA 85 Debuted today!!!
[quote]ORIGINAL: RCIGN1 Before someone gets on here and complains about the cantilever crank, the problem with the DA 50 crank was not the design, it was a crankpin hardness problem...There were about 1000 softer pins mixed in with the good ones..Short of doing a Rockwell hardness test on all the pins there is no way to identify the bad ones, the manufacturer has to trust the supplier....The bad ones were replaced...The last 5000 or so DA 50s had ZERO crankpin failures... [/quote] The way it should have been done is for DA to randomly test parts for quality, let's say they test one out of every hundred, or have the manufacturer provide certification tests for each batch produced to verify quality. That's the way it's done in my business. New suppliers aren't trusted based on nothing, they have to earn the trust through a quality program.

My AW 33% Edge with 3W-100 calculates to a little over 60 mph with a 27x10 prop turning around 6500 rpm. However, don't really know what the actual pitch of the prop is and can only take a guess at unloading in straight and level flight. A police radar gun showed 64 mph, which correlates.

RE: 3W 100 quits in Knife Edge
You can check out your theory by swapping your carb with another one from a 3W-100 or 106 that runs well. If you find no change after the carb swap, then I would start looking for a crankcase or bearing seal leak. Best of luck.

RE: 2 Blade or 3 Blade
Mejzlik 27x10 for IMAC, because it pulls well and is not too noisy if you use throttle control in level flight. A Mejzlik 25x12 3-blade is a quieter alternative, but a lot less vertical thrust. If your plane weighs 29 lbs, the 3-blade will be doggy on hot days - expect around 5800 rpm on the ground. A Menz-S 27x10 is another alternative, pulls about the same as the Mejzlik 27x10, but will be louder. Spool up on any wooden prop makes them better for 3D. Prop pull won't be critical in Basic or Sportsman classes of IMAC.

RE: 40% 260 on a Diet

RE: 40% 260 on a Diet
[quote]ORIGINAL: wgeffon I dont know much about Tensile strength but are are you saying that the covering will help hold this plane together? I've seen covering (Monokote, Ultracote) split because of loads on a twisting airframe. [/quote] Yes, the covering really adds quite a bit of strength and stiffness to any model. It is the stressed-skin concept of engineering. Stresses are highest in bending at the surface of a beam (or wing for example). The covering is weak in compression, but if one side is in compression the other side is under tension. Competition fun fly airplanes have used this concept for many years. Ultrakote is much better than monokote (for strength and stiffness of the plane) because it doesn't tear (not as brittle) as easily. However, there is no easy way to predict if the total airframe is strong and stiff enough for the flight loads. Proof comes when it flys.

RE: Two Cycle Oil for Air Cooled Engines
No google for you. That's OK, I googled. http://grounds-mag.com/mag/grounds_maintenance_appraising_aircooled_liquidcooled/ Liquid-cooled vertical twins from Kohler - new Aegis liquid-cooled engines Diesel Progress North American Edition, August, 1999 by Mark McNeely In an effort to offer its customers an engine choice - liquid-cooled vs. air-cooled - Kohler Co. has designed and soon will begin production on a line of liquid-cooled, vertical-shaft, twin-cylinder gasoline engines initially targeting lawn and garden applications. The new Kohler Aegis engines build upon the company's Command series of air-cooled engines and will first be offered in output ratings of 17, 20 and 23 hp. "The Aegis engine program was developed from a need in the marketplace for a more advanced liquid-cooled engine," said Cameron Litt, product manager for twin cylinder engines for Kohler's Engine Division. "Not that a liquid-cooled engine is better than an air-cooled engine, for each has its own distinct applications and advantages. "Our customers have asked us to produce a liquid-cooled engine for the commercial and premium lawn and garden markets. With the addition of the Aegis engine, we can now provide them with a choice." The first Kohler Aegis engine to be produced - the 23 hp LV675 - is currently undergoing final reliability testing with production parts and is scheduled for full production later this year, according to Litt. "We're starting with the 23 hp first, then we'll come down to the 20 hp LV625 at the end of the year, and the 17 hp LV560 in early 2000." The Kohler Aegis engines feature a unique radiator design that utilizes oil cooler technology from heavy-duty off-road applications for a more effective heat transfer, Litt said. The patent-pending cooling system features a radiator arranged in a semicircular fashion under the engine cover, with the cooling fan in the center. The split core radiator, manufactured by Long Manufacturing, allows isolated coolant circulation from each of the two cylinders. "We have a parallel flow cooling system, where the water from the water pump is split, sending half to cylinder one and half to cylinder two," explained Jerry Reineking, supervisor - design engineering for new product design. "The water flows around the cylinders, up through the cylinder heads, combines in the front of the cylinder heads in the intake manifold, where there is a parallel passage in the manifold for both water and air. The water then splits through the two different cores of the radiator and then combines and goes back to the water pump. "We are using a lost-foam casting process for the cylinder heads," added Reineking. "This process allows us to overcome the limitations associated with die casting. With lost foam, we improve the flow co-efficients of the intake air side. We also performed a computational fluid dynamics analysis to make sure that we have proper water flow within the head. Through the CFD process, we were able to tweak our design before the prototype stage, resulting in a more uniform temperature distribution." The cooling strategies for the Aegis engines have revealed some impressive reductions in oil and cylinder head temperatures for test engines. Under hot ambient operating conditions, the liquid-cooled units have recorded oil sump temperatures 50 [degrees] to 75 [degrees] cooler than air-cooled models, even though many air-cooled engines use oil coolers. Similarly, the spark plug temperatures have been 175 [degrees] to 225 [degrees] degrees cooler on the Aegis engines than air-cooled models. "As a result of the reduction in operating temperatures," Reineking said, "we are currently evaluating the possibility of extending the oil change and oil filter maintenance intervals. Our air-cooled Command engine today is recommended at 100 hours for the oil change and 200 hours for the filter. We are confident that we can significantly extend both of these intervals with the liquid-cooled Aegis." In addition to possibly extending the maintenance intervals, Kohler is adding another year to its standard engine warranty. Aegis engines will be offered with an unprecedented three-year limited warranty "out of the box," Litt said. Another unique characteristic of the Aegis engine is its easy-access air filtration system. It has been designed to provide maximum filtering - 200 percent more surface area than standard air cleaners - while still maintaining the engine's compact envelope. "We are using a specially designed air cleaner element and pressure fit sealing that, during testing, has performed exceptionally well in preventing dirt, dust and debris from entering the carburetor," explained Litt. "We believe that this air filtration system performs as well as heavy-duty commercial types, without the additional cost." In order to position the Aegis engines alongside Kohler's existing air-cooled Command engines, the company's engineers embarked on an accelerated development program that focused on keeping the new engines cost-effective for customers and, ultimately, end users. "To get to market quickly, our starting point for this 18-month program was our Command air-cooled engines" said Reineking. "Many of the internal components of the Aegis engine are the same as those used in the Command models. Same piston, connecting rod, rings and starter, the control system, hydraulic valve lifters, and the governor are all components used in our Command engines" Reineking added. "These components have proven to be successful in the field; we didn't see a need to redesign those parts."
