Blueadventures

Flew the Nynja to Old Station Flyin during late May 2022. The E-Prop performed well.

Also, a way I check the sensor and whole circuit is at engine service time start engine with the fuel tanks turn off, after a while the low fuel light needs to luminate. I added the savannah collector / surge tank to my build and it give reassurance when low on fuel as if the collector tank is not filling from the two wing tanks then need to land within 15 to 20 minutes or a bit longer. Will get you in preparation mode with some added flying time.

On my install I have them routed into a 1/2 i.d. tube that drains to lower edge of the firewall. (can not just extend the vent hose as it is a set length; so important the hose goes into a larger diameter i.d. hose or drain pipe.) So no chance of dripping onto exhaust. However if ever leaking fuel a back fire of exhaust could ignite any vapor from fuel on ground etc.

Every two I think, Yes the big bang would have been new to some. Biggest on Sunday morning 6am.

Also cloud forms in the mass of air your in, had it happen.

Thanks Scott, Yes was Ross's Its going well and looked after by its current owner Ben. Sunsets were colourful also.

Had a great time at Old Station caught up with Jack and Bennyboy. Great flight down early Friday and the forecast coastal headwind was present. Had and invite to great with two mates in their planes to fly home at 500 ft most of the way and what fun that was.

There is a post on youtube about manufacturing a redrive for a Subaru 4 cylinder by Mike Hille. Nice work, he's a mate that live around the corner form me and does nice work, may be of interest to you as he also discusses his engine in this build and he pervious Zenith 750 build from raw material not a kit.

16E good I have one, ask a price from Ian.

To add to Yenns comment in short a PLB is samde alert function as an EPIRB; however the battery transmit period is about half that of an EPIRB, the EPIRB is designed to float upright when deployed / floating in the water, the PLB is a little dear to purchase and the PLB is smaller more compact. I personally have the 'kti' brand in my Nynja. Hope this helps.

Mark and others I fitted one of the units about a month ago and totally impressed with the product; very impressed with the s/s 'r' clips that prevent it being knocked off the mount hooks, the cover over the control panel to protect against the environment, etc. Double thumbs up to the unit and is practical extras and also the packaging that it was shipped in. Cheers.

I have a kti brand and its small, havn't had to use it yet. AMSA Beacons lists all the approved brands and models. Cheers.

Maybe worth a try for him to check the carby up inside where the main jet screws in as there may be some build up of deposits there. I had this happen on a rotax 80hp UL in a skyfpx with fibre glass tanks. Took 6 weeks of trial, parts and hair pulling to find the issue. When cleaned the engine ran smoothest it had ever. Before that always had a slight bump at cruise rpm and if I pulled the carb heat about 2mm it would go away. Always thought of adjusting or placing a spacer on the back of the carb heat knob. Maybe what's happening in his single carb Jab.

IF you can get to Old Station or another flyin near where you live speak with some builders. Cheers

Join EAA and Kitplanes is a good start and money well spent about how things can be done.

Two of my beliefs regarding Rotax 912 UL and ULS engine operation are:- 1. For any engine / prop set up that achieves 5,200rpm WOT in climb or S&L is to reduce rpm by at least 100rpm within 5 minutes as the engine is fully loaded / stressed. 2. Best to set prop pitch to achieve rpm for WOT at 5,800; and don't run more than 5 minutes at that rpm. Maximum continuous rpm to be 5,500. Then considering that most installs have springs set to pull throttle to max rpm if throttle linkages brake; so should the throttle linkage brake and carbs go to 5,800 then you will need to stop engine before exceeding 5 minutes at 5,800 otherwise serious dame may occur to the engine. Therefore a perfect setup in my opinion would be to set throttle / prop itch for 5,800 and have adjustable high throttle stops that prevent exceeding 5,500 in the event of a throttle linkage failure. Also when my WOT setting is achieved I will never run at that rpm continuously. At present WOT is 5,450 and if I was to run at a continuous rpm it would not be higher that 5,350rpm.

I'll measurenext time at the hangar and let you know. also on the prop image on the floor you get an idea of distance ratio, Going out now so I'll look later.

Thanks Mike; I have been a follower and like Roger Lees comments and info. My KISS for any 5,200 if set is to after takeoff drop 100 rpm to 5,100rpm. Was doing this in 2012 on with my UL 80hp in a Skyfox. I am an advicate for the 5500 to 5600 seting to date and for now have 5450 rpm WOT s&l and I'll record how this goes then make adjustments. Want to do some flying trips and looks like not many good days between now and end of month Old Station trip.

Position is as per manufactures spec (page19 if you have a copy) the edge where the titanium leading edge meets the carbon leading edge. Initial pitch set with the supplied guage and then I follow up with the laser pointer. I'm in early days with this prop and have been involved in pitch setting of some E-props in Tractor and pusher configuration with 3 and 4 blade modes. Later on I will adjust for 5500 - 5600 and higher; but for the next month or so will settle at this and record performance over long legs at set rpms.

Hope their not $20 and ticket then 🙂

Your getting a bit slack I reckon; expected to be finish sanded, primed, painted and fitted by 5pm Sunday. All joke aside looking superb. Cheers.

I'll get a couple. Cheers

Not checked the tracking as prop very flexible and tip end portion has little rake as the aggressive cupping and pitch is the inboard 1/3rd. Very happy with the prop did a 1.4 hour flight yesterday (Thursday) and did some long runs s&l at various rpm settings. Will be doing a 2.3 hour flight each way at end of month will have an indication of performance after that.
