To Xenon Tom,
My goodness. You are really the one of most ARROGANT and IRRESPECTFUL guy over here. I do not understand such attitude, and such a long list of lies... Who are you to judge me, the company...??? Just a guy that bought a machine to another one that designed it along many years, involving big monies, life sacrifices...So you do not deserve to be a Xenon Owner with such attitude. Please sell your machine, as you say on another place on the forum, you have no time to use it. You prefer your Robi (one of the most unstable helicopter on the planet - Made in USA...even if it is the most popular, it does not mean it is good...), and you probably spend a lot of time on this forum because you have nothing better to do in life... You are a trouble maker, destructive attitude.
No wonder that many Europeans do not like the american attitude.
Thanks God, i do have wonderful friends in the USA, to compensate.
Now let's have a close look at what you call facts...! LIES.
IMPROVEMENT: New Style Doors - The old doors did not hold up in flight. There were several incidents where doors flew off. The factory d not even acknowledge a problem until the noisy Americans raised hell. And even then we had to come up with a better hinge and latch system.
New (actual) doors have been made here, without a single help from the USA, neither for their design. Wrong point. Good try. But is a C.A (CELIER Aviation) job.
IMPROVEMENT: Flexible Pre-rotator - This was totally American designed and installed. Raphael saw it and tested it at Bensen Days and loved it. But instead of using the proven American System (from Sport-Copter) he designed his own (inferior) system.
The system exists in Europe before americans even tried it...True about the fact that I saw it in the USA as well, nothing special with that. True we bought one (Sport Copter)in the USA, tried it, and throw it away, too poor design, too poor performance, too heavy. By the way, in one of our garages this item is somewhere and available for anyone to pick up here. So, looking at that flexible, i believed i could improve it. We made after long research, a contract with a world known specialist of Flexibles (that USA cars and more use too) from Switzerland, several prototypes were made, many tests for the final version that is now made exclusively for us. This is NOT of the shelf item...The RPM allowed beat anyone else, as the possible torque and transmissible power. So again here Tom speaks about things he does not even have a clue. Only trying to put doubts in people brain. What a smart and responsible attitude. A C. A improvement.
IMPROVEMENT: Bendix Reinforcement Collar - American designed and fool-proof. Raphael did not even recognize the problem until we exposed it. Then he did not use ours ... he designed and installed his own inferior one.
Again here, Tom does not understand what he talk about. Our actual system, include a double stage bearing, to create a good momentum holding system, when the US model has a basis one point holding, opposite to the gear contact point, anti-logic ! and of course destroying all around. See photos published earlier by you. Our system is much lighter and efficient. Oh, i forgot, the US philosophy is always: bigger is better...
This is why we see flying monsters that requires 200 hp to lift a poor payload / empty weight ratio... Another C.A improvement.
IMPROVEMENT: Turbo Inner Cooler (for RST model) - This provides forced cooling air into the turbo and modifies the waste gate to better adjust to altitude. WE DID IT FIRST. Raphael designed his own without altitude compensation!
There is no relation between an Inner cooler (Intercooler) and waste gaste... The first Intercooler was made in accordance with us by Mike Bantum in Florida, our actual representative. But we desired to improve its efficiency, and we did it the right way. See some photos in our website. There is NO altitude compensating deveice other than the original waste gate. Tom GO BACK to your mechanic lessons.
IMPROVEMENT: Reinforced Turbo Oil Sump - Provides more support for flanged tube that connects to engine to relieve some of the mechanical advantagethat can cause the tube to fail as a result of engine vibration. ANOTHER US IMPROVEMENT.
Unfortunately for you Tom, this was done directly from the factory. Maybe you thought about it, well done, but not at your credit.
IMPROVEMENT: Better Fuel Filtering - to replace the factory supplied paper canisters. In the US we switched to a dual port marine fuel filter assembly with a spin-on filter element. It provides better filtering and water separation, with a place to drain off water if it accumulates. ANOTHER US MOD!
This is a true US and stupid mod ! If it was that smart, we may have integrate it. Why we did not ? Simply because it is expensive for nothing, heavy for nothing (oups sorry, this is the american way). Our "basic"dual filtration system is absolutely proven today, as for a few grams of technology, the special filtration fiber, does react with fuel dirt by changing color, making it so easy to spot when change becomes necessary. How much it cost ? 3 Euros... Weight ? 25 gr...safe and proven. Besides, our fuel tanks are made from certified and fuel and fire proof resins, that DO NOT attract moisture like US models... Also, each of our tanks is equiped with a low point and a special shape with drain valve, to guaranty to catch the big dirts. It works and is approved today by civil aviation. NOT A USA IMPROVEMENT BUT DEGRADATION of design.
IMPROVEMENT: Primary Fuel Pump On/Off Switch - It is a safety switch that remains on until you intentionally lift the cover to turn it off. It allows you to turn on the master switch without having the pump run the entire time. AN AMERICAN
MOD!
THIS IS THE MOST STUPID AND DANGEROUS MOD YOU COULD COME UP WITH. Why, simply because this is playing with life. Just imagine a passenger curious about this strange switch and test it... The proper way to use avionics without having the pump running by default (a safety good thing) is so simply by installing a switch for direct supply to avionics. And we do it since long time on customer request.
You are now demonstrating Tom, that indeed you are a dangerous person for aviation.
IMPROVEMENT: Heavier Trim Spring for pitch trim to give more authority. YOU GUESSED IT! First "made in America".
You threat Europeans like piece of ****, you deserve the boomerang effect Tom. The trim spring improvement was also made by C.A. If you did or someone did it in the US in parallel, great no problem, but no one FROM the USA told us about... Like usual, you NEVER communicate with us. Guess why your website Xenon-owners is NOT linked in our manufacturer website...??? guess why ??? dont you think the Xenon owners would deserve a bit more intelligent attitude from you regarding us ? Dont you think it would be smarter to collaborate intelligently with us ??? Nooooo.......... too hard for you and your stupid proud. All other distributors / owners aournd the workd do the right way with us... YOU ARE THE ONLY ONE ALONE. I RECOMMEND THE XENON OWNERS TO HELP HIM CHANGE HIS ATTITUDE or to initiate another website in connection with us. As we are very open and happy to communicate both ways.
IMPROVEMENT: New Location for Cyclic Strap - We did this first. Then got word that the factory had an ingenious idea for the same thing. (The cyclic strap did not do a good job of keeping the rotor head steady during taxi operations.)
Again, poor Tom...you lose your mind. This was done looonnng ago... !!! NO USA MOD.
IMPROVEMENT: Larger Oil Cooler - Many owners experienced red-lining oil temperatures. THE FACTORY DENIED THERE WAS A PROBLEM. We adapted to a large oil cooler for better temps. Now the factory acknowledges it.
This USA mod is a non sense. Because adaptating car radiator simply do not work. They are not designed for air use, for flow problems. Instead since looonnng time ago we use a dual ROTAX radiator, for those who need to fly in hot places. WE DO NOT acknoledge this USA MOD. Pure invention from Tom.
IMPROVEMENT: Split Cowling - If you've ever had to get to the Xenon engine and needed more room than the two access panels give you ... then you know the hassle involved in removing the main cowling! You have to remove the prop, pre-rotator assembly, push-rods and many other items to get it off. With the split cowling modification you can easily remove each half of the cowling. We did it here FIRST!
Another cool lie from Tom. The story is this: it is true that it was not easy to access completely to the engine for an annual check for exemple. Customers around the world did ask for this improvement. So we did modify our molds to implement that mod. I think Tom made any molds ??? I have heard that some customers decided to modify it directly, saving the cost to change them. No problem with that. Understandable.
Bottom of the line = customers smart request = correction from the manufacturer.
IMPROVEMENT: Throttle Cable Splitter - It is recommended that a new throttle cable be run to a new splitter which branches out to the dual carbs. The splitter is available through Lockwood Aviation Supply. It is more precise than the splitter built by Celier Aviation.
NOT APPROVED ! But we are intelligent to have ordered one from Lockwood, but again that part was thrown away, we lost out time and money. We admit, that our early version was not good. So, we went to the drawing board, and we designed a smart part. Today approved by CAA (civil aviation authority). Why we did that ? Simply because by mesuring the Rotax vibration frequency, we discovered that it was necessary to stabilize the splitter. This is why today our splitter is made from aircraft certified tube (the outer gold part) and inside is a smart bronze and with an exact weight, to "sing" accordingly to the Rotax harmonics. Bye bye your " improvement" ...
C.A. job is correct.
IMPROVEMENT: In-Line Closed Air Intake System - The old FACTORY system pre-heated air and was susceptible to dust and debris. For cooler intake air and more air volume, US owners added a naca vent, then directed air through a K&N Universal Cold Air Intake Assembly.
The system you talk about was indeed wrong. That was the early stage of developement of the now famous RST. Indeed, your mod IS NOT implemented by the factory for dynamic flow reasons. We of course tried that too. But our actual system, provides a dynamic input to the turbo, thus discharging it from unnecessary forces, making a longer turbo TBO...
Wrong USA mod.
IMPROVEMENT: Fuel Check Valves - If you want true redundancy in your fuel system, you need to extend the fuel lines from the output of your fuel pumps and install check valves in each line along with pressure sensors. Then, one of the lines fail, the good pump will not pump back through the bad line. The pressure sensors will alert you to the bad side immediately. ANOTHER US MOD!
This was done long ago for the European German market as it is obligatory. For the other countries was not. We simply later decided to integrate it as standard. Beside the actual RST fuel pumps DO integrate a automatic valve. NOT USA IMPROVEMENT, but C.A.
IMPROVEMENT: Turbo Oil Check Valve - Xenon RST Turbo units do not have seals in them. So there is nothing to keep oil from flowing into the "dry" side (air intake) of the turbo. The new check valve installed in-line with the turbo oil line will keep oil from siphoning back into the air chamber, GLORY TO THE US!
Glory to the US... Poor Tom...
In fact i will start to forgive him as i see his technology level is close to null...
But indeed, we do have a valve. The Turbo oil valve is original from Rotax Austria, and was adapted to the RST engine, and by the way the correct name for this engine today is: CA912ULT, as it was re-certified. We dont do mods just like that here in Poland... So the valve is C.A. made but with internal Rotax parts.
IMPROVEMENT: Improved Door Hinge Pins - The hinge pins should be replaced with bolts of the diameter so a locking nut can be used. Previous door hinge pins loosened from vibration AND EVEN THE NEW DOORS FLEW OFF. God Bless the USA.
Yes i will repeat after Tom : May God bless america... Big need !
This is also done by the factory since long time. But in the USA Tom feels the Xenon gourou, and do not need to communicate with the factory, otherwise he would have known it much before. Anyway, he is smart enough to have done the mod. No glory.
Our doors DO NOT fly off, when people simply do not forget to close them !!!!!
Would anyone want to say that our certification people at the CAA dont know they job ?
I would love to see any american gyro try pass our certification... Big laugh...
IMPROVEMENT: Straight Exhaust Pipes - The original muffler on the Xenons have been know to crack around the mounting flang where or around the weld that holds on the pipe which ataches to the engine. This occurs because the muffler hangs so far out without adequate reinforcement. The muffler also gets very hot and causes high temperatures under the engine cowling. WE BUILT NEW STRAIGHT PIPES FOR BETTER POWER AND LESS HEAT!
What a beautiful final lie Tom !
Indeed, i will agree that the earlier exhaust was not perfect. Yes we had some cracks, yes it was heating things around.
YES I DESIGNED the new and perfect exhaust, as for all the rest of the system. You may have copied what we have done here, jalous like you are about me, as you may never have accomplished anything like it in your life... Where is the point of jalousy...??? Shall i be jalous that an american first steped on the moon ??? Tell me more about the Wright Brother, with respect for them...the American big mouth like to say about them to be the first motorized airplane in the air...ah aha... But french Clement Ader was much before...But for sure, we are not as good as you to lie, and to organize the " show" and let people believe what is right to believe, even if it is not true.
I now want to apologize here for the American people, as i do love you and your country. So much achievement was done over there. I simply put here Tom back in its cage, where he should stay humble and quiet.
And i could go on and on...hum, i read this somewhere up...
So TOM, as per ALL the previous messages to you, you do not change, you like to be the trouble maker, the gourou, to get the credit of imaginative improvements. Fine. But you always refused to come over here, face to face with the Xenon designer and its wonderful and dedicated team, that with your stupid message you insult deeply and repeatedly without respect. You do not feel necessary to have ANY contact with the factory...what an idiot attitude for someone driving the Xenon-owner forum.
We are finalysing our plans to be back in the USA very soon, as we open our own company there. We will then be able to supply kits, spare parts, advices, customer support. We will definitely built another Xenon-owner website, so you shall be forgetten. Fo the best of all and owners.
This is the very best answer and motivation for the american people, that we do not abandon no one, we are proud of having good fans in the USA, and they deserve that we make more efforts.
As we do care very much about our customers, we also do acknoledge our mistakes and snags, we do have the strong motivation to improve all that is possible.
I hope readers will understand my fight back, i do not tolerate to sacrifice my time and life for such guy like TOM lies and insults. But things need to be put back on tracks.
Critisize is easy in an instant and for free, desiging and building a winner machine needs years and millions...
Bye Tom.
