General Helio Discussion / Re: G0-435 Piston Rings

Your welcome wish the information was of help. Wish you good luck with the cylinder replacement.
Hi All,

Thanks for all the replies and help. Oil rings are plentiful. Unfortunately none of the above had any compression rings but I finally found a set at Lycon. Originally they said that they didn't have any.  They had a bunch of 435 cylinders and were waiting on some. They called us back 2 weeks later and had some. Not sure where they got them or if they had them made. The cost was $200 each (2 per cylinder). Presumably they now also have cylinders ready to go.

Best Regards,

For those that don't already know c/n 600 is back in the states it will be interesting to see if it is reregistered and eventually flies or will if it be sold as parts.

Here is an article that features c/n 600 as 63-13095 while with US Embassy in Phnom Penh, Cambodia during S/Vietnam era.

The article has 2 glaring errors first it shows a photo of a U-10D s/n 66-14348 which never was posted overseas and at the end of the article it listed the a/c as never flying again after an accident, but here c/n 600 is in Wasilla, AK.

I will open the article above.

Here is an page from flight international that probably should be posted under c/n 2501 but since there isn't much here and has some interesting speccs for the H-500/U-5 and it has a picture of N10036 c/n 6 I decided to post it here.

link to c/n 2501, N5444E http://flyhelio.com/smf/index.php?topic=1138.msg4479#msg4479

link to Stallion c/n 1, N10038 http://flyhelio.com/smf/index.php?topic=1204.msg4666#msg4666

opened the article at the bottom of pictures above

Might have a lead on the compression rings. JAARS sold 61ea. of 74984 to Johnston Aircraft Service Inc, 559-686-1794, in 2017. Check with them as I can't imagine they used them all. Jim

Hi Guys,
Thank you for the leads. I found an oil ring but have had zero luck finding the 2 compression rings. I'll certainly try J & J (above) but I'm not holding my breath. I've called all over the country and no one has these. There are some custom ring makers that can make them if I had the specs but I can't find the specs. Anybody want a cheap 1956 Helio H391b that just had an extensive annual and is good to go minus 2 compression rings on #5? (and yes, I'm serious...shoot me an offer).

I could have remembered incorrectly, but I believe Gordon has a rudder in his parts stash.

I have a top to an H250 that you can cut down to fit, I know they would do that when converting from the 540 to a go480 but I'm not exactly sure about a 391. I do have a steerable tailwheel assembly minus a tire and wheel.
