New Engine Technology?
 

Just wondering if anybody has tried or heard of anybody using this technology? Sounds like it'd be perfect for scale pylon racing!

Wow, April 1st. Only 23 more days till Easter.

G'day

Yes, we use that technology here all the time but especially just after March as the weather cools. Sadly, it only works for one day each year.

Hmm, at those rpm levels you would have to use a very high quality oil to avoid premature wear. I remember a product advertised early one April several years ago called Parflo Oil (I think it was spelt like that). The manufacturers of this oil had managed to reduce the coefficient of friction to slightly less than zero. Any engine that used it would actually have negative wear.

You would use it straight for an old clapped out engine to improve the compression, or mixed at an appropriate % with standard aeromodeling oils (castor or synthetic) to maintain the pinch in an ABX type engine.

Must see if I can find some to try out when these engines come out.

Yes, we are constantly striving to achieve "The Best" performance these days.

I remember a few years ago one April, an electronics magazine published an article on "The Ultimate Loudspeaker Connection System" for the true audiophile. The normal copper speaker wire was replaced with 1 inch plastic tubes filled with liquid Mercury. This system was guaranteed to give absolute accuracy and "musicality" if at a rather high initial setup cost. A number of the "golden eared" fraternity actually installed the system and proclaimed that the results from the system was noticeably superior to even the finest low Oxygen Copper wire and that it produced a particularly "fluid" rendition of the music.

All agreed that the small downside of Mercury poisoning was a small price to pay for the improvement in the sonic experience.

Thank god it only happens one a year....[>:]

.

It would also have negative friction which would mean a shaft would accelerate once turned over. It would be perfect for a zero displacement engine.

RE: New Engine Technology?
 

the bad part is, I don't remember what year it was, but I remember that article from when it first came out...

RE: New Engine Technology?
 

Hey fizz, you're a bigger man than I because there's no way I would admit that. LOL

RE: New Engine Technology?
 

Couple that engine with the Turbo Entabulator tranny [8D]

That Turbo Entabulator tranny vid was so good and how he kept a straight face...I talk to my customers and apprentice like that some times..Get away with it most of the time...

RE: New Engine Technology?
 

I'll bet I can tell you the DATE it came out! (April 1)

Here are a couple not all of you will remember:

I had a Orbit radio system many years ago. Unfortunately, mine was not a six meter version though.
:D

RE: New Engine Technology?
 

Hey Spaceworm - greetings from the designer of the Orbit Six Meter Transmitter. I donated it to

the MA Museum years ago, no idea what they did with it. Surely someoen there flew it. Eloy Marez

RE: New Engine Technology?
 

I still have a one meter Orbit with round chrome gimbals and 6 channels, but it is on 72MHz. [8D]

I would imagine that the engine is Eco-friendly as it looks like it has an inherit potential to "windmill". The latest version also incorporates a ceramic coating on top of the piston to ward off the tremendous heat produced in it's combustion chamber. The outside of the engine is also hi-luster chrome plated to help it slip though the wind easier.;)

RE: New Engine Technology?
 

Excellent point Sport Pilot, I hadn't thought of that. There is a huge synergy here. It's almost like Parflo Oil and the ZDE were made for each other.

I thought they came out with a supercharged version later. New and improved MKIII with quad crankshaft bearings to handle the heavier load.

RE: New Engine Technology?
 

I read an article some years back of a simular engine.. sort of. This was the Varible Displacement Engine from Professor McDonald. The PhD MCD VDE (for short) could, once mounted in a model, change the size or displacement, making it a bigger or smaller engine. PhD MCD had his demo version mounted in a telescoping wing and fuse platform (remember those? I think his was the Sterling version of the Incedible Hulk model, that everyone copied, well it was a nice trainer, as long as you didn't let it get away from you), it also used a bladder tank to adjust for the needed change in cc volume.

I'm sure its not that much news to you guys, I'm well aware that I'm not the only one who saw that article. Just wanted to update the professors work. PhD MCD is now working on a standard airplane (wings and fuse stay the same size both on the ground and while in flight) but this one is an electric. The motor isn't a brushless, instead its a modified version of an early 1980s design, The Compound Wong by Mr Wong. PhD MCD has vet to release the mods he has done on the Compound Wong, but he did claim in last years (to the day) news article that his plans are to circumnavigate his plane around the globe on one flight. To do this he has installed a charging unit in the plane that uses the old tried and trued technology of cold fusion. Test flights and adjustments are planned for this year and is tight because the voyage flight is scheduled in exactly one year.

I cant wait to see this on Fox news next year. I think PhD MCD executed this very well, using the old technology instead of trying to re-invent the wheel. As they say, Keep it Simple Stupid!!

Another club member actually offered me one of those GHQ engines once. I wanted $50 to take it, but he only had $34.67 on him.

RE: New Engine Technology?
 

The GHQ was famous for being the only hobby engine that was made continuously during WWII. While everyone else was shifted off to made wartime materials, they got to continue making engines that didn't work. amazingly enough more than 100,000 of these things were made. Jillions of brand new unused GHQ engines still exist out there someplace. No one could get them to start and they'd toss them in a box to forget about it.
They have a nice story about them here, from the pic of that one example, the main problem is the cylinder, piston and rod fit.

RE: New Engine Technology?
 

IIRC, until maybe the mid 1950s, you could still buy a GHQ from AHC for as low as $3.95. Made interesting paper weights.

That club member I mentioned actually claimed he had his running. Could turn a 13" prop over 5000 rpm. All he had had to do was hone and chrome plate the cylinder, turn a new piston to replace the stamped original, install a bronze shaft bushing, and a couple other little mods.
