I just got word from Wren Turbines in England that my Wren 54 has now been upgraded to a Mk3. This means 14 pounds of thrust for the same size and weight. It also includes a new (better looking) case and exhaust and a new FOD screen and starter. Should look great under the R54.

My R54 is now standing on its wheels at last. Covering starts soon.

Who is going to be first to fly their 54??

Regards

Hi Dave,

Sorry, this is a little bit OT, but since you're idle waiting for your turbine to show up ( ), here goes:

I really like your R54 covering job/color scheme! Can you tell me the order that you covered it, and the colors you used? Did you start with an overall covering job, and then trim it out, or how did you get the multi-color effect (particularily the wings)? Can you provide some details?

Thanks!

John

John,
Not off topic at all. The covering is Monokote all the way. All pieces are seperate with no or little overlap. The gold trim tape takes care of the seams. The wings are fully sheeted in anticipation of the color scheme. I cover in the usual order...bottom first and work forward. All seams face down, out, or aft. 1 25 foot roll of White, 2 6 foot rolls of Missile Red, and 1 6 foot roll of Royal Blue. The "canopy" is aluminum. 2 rolls of 1/4" Gold Carl Goldberg tape on the seams. Turned out pretty well for a flying machine...NOT a Toledo finish though. I made card stock templates of the sunbursts both for the white and blue. The sunburst is on the top only for visual orientation in flight. The stab and fin are identical top and bottom. The red leading edge stops short of the tip to allow the white to show. Makes a great visual reference when dropping below the tree line on final...sorta like solar powered landing/tip lights! A tip I used when I flew Pattern competition in the late 70's early 80's. The covering added @ 11ozs to the bare airframe.
Military jet colors were never considered as being way too drab. 53 year old eyes don't need THAT handicap! I'm not blind mind you...It's just that I'm flying a model that's worth more than the car I drive at the moment!

Hope this helped!

All the pieces to the fuselage are glued on and well into the sanding process. Anyone want to come over and help me with the shop vac?

Tomorrow its cutting out the hole for the nose wheel well and 220 sanding.

Made myself a neat little tool which gave me a perfect 30 degrees for drilling the hole for the rudder cable.

Cheers,

Bruce is sending the mount.

NOT ALL day... Just got back in town from business. Hoping the mount arrives tomorrow so I can get it installed. Bruce tells me that some drilling and tapping is required to fit the P60 to the R54. I'll post pics of course! I'm making arangements to visit with some experienced turbine guys..(JetCat to boot!) this Sunday. I'll keep you posted. NICE LOOKING TURBINE!

Well...The P60 is installed and we'll run her up tomorrow. I have some help with a experienced JetCatUSA flier. I'll post some more pictures tomorrow...Heck we might even have a short video of the first spool up! In the meantime look at the pics below. They are the turbine and support install.

Hey gang,
We got the P60 to fire up today. Took several trys as we had to adjust the kerosene pump voltage at idle. Nick Yuhasz and Gary Nichols were a tremdous help! They checked the plane out "head to toe". Caught one line not safety wired to the nipple. Had a bit of trouble getting the retracts to lock down we I got there. Took us about 10 minutes to find the problem.......I drilled a 1/16 hole for the gas valve mounting screws...yup right into the Robart air tank! DOHHH! You can see this valve is the pictures above .....4th from the left.

Nick took some time to show me the JetCat 5.0 ECU stuff. Before we left for the day he had me review safety proceedures and do a start sequence "all by myself!" I taxied around the driveway to get a bit of feel for the throttle response. I guessed the slam time was about 3 seconds or so. Nick has the JetCat software and we downloaded the run to it and got a slam time of not quite 3 seconds! I'm very pleased with the P60 operation. Idle RPM of 55,000 and it maxed at 162,000.

Well I gotta go and order a new Robart air tank and the JetCat software! Keep building because the first time YOUR turbine lights off and runs...IT WILL BE WORTH IT!

Thank You Nick and Gary!

I'll post a video of a startup as soon as I get it into the computer.

Dave "still grinning" Rigotti

Dave, glad to hear the P-60 worked for you. The max rpm of 162K is 3,000 below the factory default max rpm limit. Did you guys turn the engine down? Just curious here, no issue if you did. If you didn't I would run it again and let is sit at full throttle for a few seconds to reach the max rpm and let the ecu learn the fuel pump voltage limits at full throttle. These can vary slightly from our test stand due to differences in the drag on your fuel system.

John,
Good point. We really didn't have it running at WOT for any real length of time. I'm pretty sure the software graphs showed low 160's, not 165,000. We did not turn it down..that I know of. Nick was very good "getting into and around" the ECU. I'll check IF it got reduced in error. Nick was very impressed with this "little" engine. He was grinning almost as much as I was! SLAM time (the lack of) blew him away! Methinks he's gonna get one!
Is there a "break in" required?

BTW...Can Exxon (BP) 2380 turbine oil be used instead of Aeroshell 500?

We also talked about making a FOD screen and got some measurements from the turbine body.
I'll TRY to call you tomorrow on placing an order...

Thanks for your help!

Dave Rigotti
