(I have pages of numbers from BPE on my Lycoming. Its all boring stuff to read, but it is there, it was done and makes good business and engineering sense)

Hire someone like Sonja Englert to go over the TV issues and publish her report.

Do that and 98% of this thread will go away, you will sell more engines, and have a lot less controversy.

None of this will cost and arm and a leg, it only makes good sense. Do it and get on with life. Otherwise the discussion will never end and it will harm the business potential of the Viking.

I agree 100%
Unless he already knows the outcome.

This thread is on thin ice (rightfully so) so I'll tread lightly, and summarize the unstated feelings of many people on this thread. The manufacturer in this case has a well established reputation in the RV community. Anyone who has been around here more than a couple of years is well aware of it. If you are new to the group, the info is all in the archives, google etc.

We all owe Paul a great debt, for without his efforts in the early days, our hobby would simply not exist. In fact, one of his earliest successes was to get the rules changed to allow for carrying of passengers in homebuilt aircraft, which was illegal when EAA was formed in 1953. The below quote is from the very first issue of the Experimenter in Feb. 1953

"The feeling is running ?high?
that with a strong organization,
enough pressure could be brought
to bear in the right places that
some sort of limited
airworthiness certificate could
be issued time proven
experimental aircraft to enable
the owner to carry passengers.
It is a goal to work for."

Interesting history, but not at all relevant to the discussion of the Viking engine. And not any sort of basis to invoke Paul's name to rationalize the business practices of this company. This has nothing to do with your rights to experiment with alternative engines.

Jan,

As a future LSA pilot, I am closely monitoring powerplant development for this category of aircraft. Considering the audience that you have on this website, why are you not a paid advertiser on this forum? I believe this would promote a more open dialogue between you and your potential customers.

Regards,

Jan I think a lot of us would like to see this engine perform well, and have other choices for a power plant. Time will tell and I am looking forward to the time when Don has some time on his 12 to share his information with us. Sharing information and solving problems is what this sport is about. I will also use an alternate engine in my 12, as more information is presented. I would like to see more weight and balance, gearbox and high RPM information.

Good Luck

i am aware of most of the history, i was wondering if you knew much about the viking or if you based your "highly suspect design" solely on the what you know of the past history?

those that don't learn from the past are destined to repeat it...

I do not know a great deal about this engine package or it's engineering, and I base my cautions on the history of the company. The lack of engineering information, especially with the gear box and TV issues that others have detailed, are my basis for the "highly suspect" description.

This user continued to use the site as a promotional tool for his business. He was sent advertising information months ago, yet declined to. Was sent multiple emails and PMs asking him to stop promoting his business on the site (he chose to keep doing it).

I can't tolerate abuse, and therefore have decided to ban the account permanantly and lock this thread.]
