Flying again (finally)

Got to put a couple hours on the plane. Gorgeous weather and views despite peak foliage gone by here in central Maine.

Query for the group: Zenith Rubber Donut nose gear suspension

Query directed to all who have the system installed on their airplane....I had a chance to do some taxing and flying today after having recently installed the system on my STOL CH750 . The system is nice and smooth on the ground and notably quieter (as in silent) than the steel spring bungee I had.  Inflight was like having power steering on the rudder pedals, smooth and very little pressure for any required rudder deflections.  HOWEVER...during ground taxi, I get into a mainly continuous "bob"…See More

UL engine mount and Viking steel spring system

FYI...Recently noticed that the center thread rod of the Viking steel spring system was making occasional light contact with the top center engine mount tubes.  This happend to both top tubes and grazed the powder coating off just about down to the bare metal.  That was one reason I elected to swap out to the Zenith rubber puck system.  Also felt that the Viking system was harsh and noisy unless on smooth pavement.See More

No, no, no!!!

This UL is starting to make me lose "the love" just a bit.  20 hours on the rebuild and postflight inspection discovered this!  (Sigh) - gonna pull the prop flange bolt and see if the oil stop on the end of the crankshaft is leaking.See More

Priming Fin repair

Repaired "trailer" damage this Spring, while I'm painting my Stab fences, thought it was a good time to mask and prep and paint the repair.

David,

sorry about delay, not good on this Zenith site!  Looking to get a set of Zenair plans to install my floats. Do you have a set I could purchase/copy?  Thanks,

Hi David, I am curious about your UL Engine , what was the problem that you have to change the #3 Cylinder . And how many hours on your Engine. Tks Wayne

David, I saw that you are interested in Datum skis. I have been flying with the skis for 4 years and am very satisfied with them. If you have any questions forward them to me and I will be gald to answer the best as possible.

David,

You asked what we were seeing with the bad injector.  The above is typical.  #3 cylinder just was "not tracking" with the others. 

Digging a little deeper, it is a bit hotter than others at idle (lean, where everything should be very rich), gets even hotter if the power is up only a tiny bit (even leaner), and actually "goes cold" when the power is advanced anywhere above about 1500 RPM, because it gets so lean it is not burning. Too lean for the plugs to ignite. 

And... we thought this was a bad injector for a long time.  After chasing down similar problems several times, we came to the conclusion the injectors were fine... that the ECU had an inadequate ground.  

Conclusions:

First, check that all EGTs and CHTs "Track" each other in ALL conditions before first flight. 

Second, check for very, very, very good grounds in an airplane that is so dependant on electronics. DO NOT count on the frame.  Strap and/or "Star" (i.e. home run wires) everything. 

Feel free to ask questions. 

P.S. Graphs produced from Dynon logs via custom software that I wrote.  Feel free to send me a log file if you want it graphed.

David,

You can reach me about the charger at ksatter@Verizon.net ...  I can get it off to you by Monday.

Hi David. Hey, need to ask you about your experience with the Skytek tank. I talked to Keith at Skytek and watched the Rotax videos and am impressed with the product. Not impressed with the price and not sure about the 1 gal capacity. They say 7 and half minutes at full power for a Rotax engine if you are down to just the header. Assume then for a UL it would be about half that. I plan on a UL350is. I have seen the pics on your installation but do you still think this tank is the way to go?

David, too funny, I happened to zoom in on your dog because I kept thinking he really had a short muzzle for a German shepherd, and he looked like a cool mix………..then I saw someone stole his legs…… Pretty cool dog, purebred? I don't see many out here with shepherd markings like that.

nice to here from you Dave your welcome to stop in anytime.

Our goal is to move project to Caribou this spring for assembly, and begin testing by November.

Your postings show fine work and great progress; the State of Maine is a great match for the 750 performance.

Looking good ! Keep up the good work...It will eventually FLY...and well too !
