Everything we said it would be, it has turned out to be. The Viking Honda based engine has become the #1 aircraft engine of choice for all sport aircraft builders with over 25 orders at Air Venture Alone.

Jan - I have a 701 and I'm curious as to rather or not you had to modify the 701 in order to maintain CG in check?... I like the sound of the engine and I like the posted specs. I don't plan on getting rid of my 912S but if the situation ever warrants that I will definitely be interested in the Viking.

Here is the weight / ballance report down the page http://www.vikingaircraftengines.com/ZENITH.html

 

We have the battery and hgeader tank behind the seat.

Thanks Jan - Very good and detailed info. Impressive videos.

What EXACTLY do you mean by that Ben?

No need to speak in riddles.

We are big boys and gals down here.

Question Jan,

Is a stainless steel engine mount a good idea?  It is my understanding that stainless tends to be a bit on the brittle side and does not deal with high stress and vibrations all that well.

 

Otherwise, I saw the 701 and talked to you about it at Oshkosh.  Looks like a good fit.

There is a wide selection of stainless steel.  We use seemless type 316L. It is an extra-low carbon version of Type 316 that minimizes harmful carbide precipitation due to welding. Typical uses include exhaust manifolds, furnace parts, heat exchangers, jet engine parts, pharmaceutical and photographic equipment, valve and pump trim, chemical equipment, digesters, tanks, evaporators, pulp, paper and textile processing equipment, parts exposed to marine atmospheres and tubing. Type 316L is used extensively for weldments where its immunity to carbide precipitation due to welding assures optimum corrosion resistance.  Also, the stresses / Vibration level of our short engine mounts are low.

Is there a specific reason for using 316L stainless steel? 316L has about half the yield strength of 4130.

 

4130 is tougher and much more resistant to bending loads, I fail to understand why you would not use it.

There are so many other reasons to use it than the #'s you list. It has great properties for the job it does, it looks very nice, it will be 100% stronger than one internally rusted through in 50 years, you can clamp to it and bolt to it without scratching or crushing powder coat or paint.  Wow, you don't even have to paint :)  Our mounts are super short, due to the Viking layout and in most instances the longest tube is 8". We run slightly additional diameter wall and it ads only a minuscule amount of weight to our very compact mounts. The Seamless 316L tubing is more expensive. Did you know most 4130 is Chinese? Hard to verify the specs? (However, a lot of Chinese parts have been getting better)

Jan,

 

  I have a friend who paid for one of your engines last year and wondered if he would ever get the engine, after many phone calls and frustrations, and false promises.  It finally showed up last month, but minus the computers, and now he wonders how long it will be before he sees them.  What is causing the delays?  How far behind are you on deliveries for engines that have been paid for? 

I posted a reply to this. Not sure where it went. That engine was shipped and we are close to sending the latest ECU and fuel pump assembly. He will receive the good stuff, fine tuned by our installations in the 3 aircraft that flew to Oshkosh. He wants to get flying and I appreciate that. He will be a great representative for Viking. We are sorry about the delay of the first engine batch. We are now one week from having shipped everything paid in full, other than some that paid in full to get us going on the next batch of engines. Back log is HUGE but all we are ready to take the challenge head on. 50 sets of parts just started production.

Jan,

 

I do hope you are more successful with the Honda, then you were with the Subaru engine.

I had my Subaru in my RV-6A for about 7 years.  VERY successful and lots of flying.  Cruised at over 200 mph and had no bad habits.  

The Viking engine has nothing to do with the Subaru.  They are completely different engines, developed at different times, with different goals and for a different mission.  

The Subaru was all about being able to fly, for the least amount of money.  The Viking is all about delivering the best possible quality, for a reasonable amount of money.  

Different time, altogether.

We are now getting ready to fly to NH after this weekend.  Will be a great trip in a fantastic CH-750 air-frame and with a Viking, all hot liquid operated heater, cranking out heat at 12,000 ft.
