701 eclipse

We put the latest Whirlwind three blade prop on our ul350is powered zenith701 and I got a picture of it with the partial eclipse last week.Fitting because it has eclipsed all the other props we have tested to date.

In August of 2011 I did a UAV job for the ARMY with a new Rotax 914. From the start the engine ran poorly. After long hours of diagnosis it was found that the magnets on the flywheel were not in Rotax speck. Rotax required us to purchase a new flywheel (700.00$) and send the original one in for credit if they determined it to be faulty. The new part fixed the engine. They accepted it back and sent me a warranty clam form. After several calls to Dean at Lockwood Aviation and three years I still…See More

Turbine Zenith 701 flew over 1200 miles

Posted on April 7, 2011 at 3:00pm 0 Comments

The Turbine Zenith 701 (742DE) flew over 1200 miles at 300’ over Lake Livingston last week in an attempt to locate a lost fisherman. We unfortunately did not save a life this time but I was sure impressed with the utility of the 701 to perform this type of search. It was gratifying to be able to help and I would recommend that all of you that have 701/750 consider letting local law enforcement know if you have time to volunteer.

Scott---We talked a while back about your ti firewall. I don't know if you've seen this on ebay, I ordered one. http://www.ebay.com/itm/TITANIUM-SHEET-ALC-AMS-4901-016-/120730460470?pt=LH_DefaultDomain_0&hash=item1c1c18a136 With your setup and the price on these you could make a little on firewalls for planes. They're accepting offers and if you bought the lot you could probably get them for about a quarter of their worth. Plus, they're in fort worth.--ben

Scott, the price is $23,500 and that includes engine mount, cowling and a bunch of other firewall forward stuff, some of it quite valuable. Reason for sale: sold my airframe.

Scott, have the main gear off, was planning to drive thursday night to East Texas and possibly come by your shop on Friday 1/21 for main gear adjustment. Does that work for you ? My camp is at Woodville.

hello scott, thank you for answering my email. i am very interested in possibly getting some prints of the driveshaft setup , so i might be able to have one made here. i also noticed that you changed drive setups with the new turbine engine , i believe that to be a newer jfs 100 , if i am successful in getting this engine running , i would like to put it in a 750 zodiac. john kreeger.               kreeger.bill@yahoo.com

Scott looks a lot like the North end of lake Livingston, I pass through frequently going to Woodville. Where a bouts is your shop ?

The 701 is in my opinion one of the best airplanes in the world at doing the job it was designed for.It is designed for the masses and is safe in almost anyone's hands. My intentions for this project was not to improve or redesign this wonderful airplane. I have a fabrication company and have all kinds of wonderful equipment and the skill to use it. I have long had a fascination with the 701 and wanted to find out what it might be like if it were built in a mil-spec manner with a turbine power plant. I have no intention of producing any more 701. My next project is a flying boat like you have not yet seen. We will be flight testing this 701 this spring and hope to take the other 2 on amphib floats to Oshkosh in 2011 It looks like we will be right at 600lbs
