I just wanted to post a big Thank You to Roger Lee for all his advice that he has posted on numerous forums regarding Rotax engines/systems as well as his prompt and helpful replies to several pm's I ...

Just to clarify my post. I don't believe the ethanol in the gas caused the Kreem to come off the tanks...this is thought to have been caused during the manufacturing of the tanks..specifically the fai ...

I flew the GSC for about a year, but finally got scared off by the 5 yr/500hr life limit by the manufacturer as mine had been installed about 10yrs even though it had less the 200 hrs. For the money I ...

I had this problem on my KF IV Speedster 912ul a couple of years ago after I had started using gas containing ethanol. I am not the builder of my plane, but it was finished in 2001 and I think was a ...

I believe it's 12MM see http://www.aircraftspruce.com/catalog/topages/diffpress12mm.php

Hey guys, I'm only getting about a 1 year lifespan on my Westach oil temp senders, part no 399S10-1.5S. They seem to quit all at once..i.e worked last flight, then not at all the next from engine star ...

Thanks for the reply, Ivor. I had tried to fix some damaged threads and looks like a made it worse. I was hoping to get a reply from someone that had used a specific product on a 912 engine. I have lo ...

Hi all, Looking for input from anyone that may used a Heli-coil, Time-sert, or other thread insert system to repair a spark plug hole/threads in a 912. I have some damaged threads in the bottom hole o ...

Yep that's something like I'm looking for...maybe even more foam around the outer edges (the leather part), but thanks for posting the pictures it helps give me a better idea of whats out there...nice ...

I have a Model IV Speedster with the standard cordura seat and back cushion. I would prefer to have more of a "bucket type" seat that kept both pilot and passenger centered in their respect ...

I have purchased my insurance for the 2 years that I have owned my Kitfox IV Speedster through the EAA program which uses Falcon Ins as the broker and the actual insuring company has been Global. I ha ...

Lloyd, there are extensive posts in the rotax forum on the subject of oil and filters , but the last post by Roger Lee about filters at http://forums.matronics.com/viewtopic.php?t=14122&highlight ...

Well, after doing some research on the product recomended by Rotax, it appears to be made by a company in Europe and is called Wacker P12. I could find no source for it in the U.S. except the Rotax pa ...

Thanks, Roger for responding, but I guess what I'm asking is why? Do the spark plugs in a Rotax get hotter than those in Lyc's and Cont's or are the NGK spark plugs more likely to be damaged by heat ...

Could someone explain why anti-seize is not to be used on the spark plug threads in the 912 series engines as I would like to pass the info on to my A&P. Thanks, Paul Perry KFIV Speedster 912UL

Lynn, from what I've read and I think the point you are making, is that the Kreem was used to seal the fiberglass tanks. If my memory serves correctly I don't think ethanol was considered a problem in ...

Hi Kirk...yes I'm flying again and I bought the R-9 fuel line, but like Lynn says I'm sure the R-7 type would be just fine. I had read a couple of posts recommending the R-9 version so I went with tha ...

Because those who had re-sloshed with tanks in wings recommended it, (the instructions on the can said thinning with mek was acceptable), and after doing it I agree...without diluting it's thickness ...

Just a follow-up (search/see Kreem problem again post). I removed wings and "sloshed out" flaking off Kreem with MEK and then re-sloshed with a 50-50 mix of Kreem and MEK. If anyone wants th ...

I'm assuming that the Kreem was coming off for sometime probably due to the inadequate cleaning of the release agent from the mold process by the manufacturer (Skystar?) as stated on this forum by se ...
