General Helio Discussion / Wingtip screws
« Last post by yukonranger on Today at 06:40:39 PM »
Hello  I have a 1400 series H295.  My wingtips have always been held on by Type A sheet metal screws into tinnerman clip nuts.   This is the wrong type of screw for tinnerman nuts (should be Type B).  The parts manual specifies AN 526 8-32 screws which is a non-structural machine screw.  The parts manual does not specify what the female fastener is (probably some type of clip nut).

What is the screw and nut used on late H295s from the factory?

Also, what is the female fastener for the fairing strips between the fusilage and the wing?

Thanks

Mike

Clarence was indeed the Chief Engineer. I meet with Clarence in his home in the fall of 1998 at his home in Pittsburg KS.  He had boxes of data. I gave him $500 for a few items that were useful. One was a study of the rocket launchers and the other the wing load tech data for the 3800 lbs gross weight increase.  BTW I sent these to someone many years and have not gotten them back.  They are part the the data backing the STC for our camera. I believe Steve Murray purchased the rest of Clarence’s boxes of data about the same time. I got the impression from Clarence that he thought, he was 92 as I remember, the carry through AD was a bum deal but felt the fix made the wing fail safe. I’ll let others decide that one.  I also met Ken Noe at his place in OK, maybe 2000.  He and Casebeer had a stash of Helio parts from the the closed factory. One item of interest was the jig for the Tri Gear engine mount/nose gear. No idea where all that stuff went.

Louis,

Yes, he's a good friend. We stay in touch on a regular basis. I'll pass along your greetings.

I was at his place when he was building your airplane so I got to see it going together. I remember the patchwork paint that it had at the time. Looks a lot better now!

Helio Modifications / Re: H-700 cowling modification to improve cooling
« Last post by jmfuller on January 04, 2021, 05:57:45 PM »
Doug, I've been watching this H-700 cowling discussion for some time and finally decided to do a map look. I'd love to get that cowling for our H-700 (along with the STC...) but Cyprus is a bit out of the way. The airport in the attached photo is not Lakatima, which I think was abandoned before H-7 got over there, but Larnaca, currently in operation and serves Nicosia. Whether H-7 is one of the planes in the photo is another question but, at least as of the date of the mapping photo, there was still a yard with what look like abandoned small aircraft with one or two that could be a Helio.

Louis,

As Doug said they were both engineers.

Bob Casebeer was the Designated Manufacturing Inspection Representative (DMIR) for the factory in Pittsburg. Along with working for Helio, Clarence Brent also had his own engineering business, Brentwing Engineering.

Louis, the question you ask about the engineers is one that probably could be answered best by Ken Noe

Steve Ruby I'm sure would have a better off the cuff answer as well.

Clarence Brent and Robert Casebeer were both engineers with the Helio factory. I think Clarence was the Chief engineer.

I believe that Clarence continued working on the Helio after the factory closed the first time as an independent engineer and Robert Casebeer worked for Helio Enterprises inc.

I think they both worked on the type certificate for the H-7/800.

Clarence developed some oher Helio STCs (now owned by Gordon Cragg) and He was the engineer that worked on H-5 (the low time Helio you speak of), H-5 was used for some gear leg drop tests. H-5 was also used to develope some speed mods Wheel pants and a modified cowling that reduced drag and gave better cooling I don,t believe Clarence ever got aroun to sumitting the paperwork. I believe it was owned by Luigi Chinetti when you saw H-5.

see H-5 here http://flyhelio.com/smf/index.php?topic=1230.msg4722#msg4722

As far as the automootive fuel that I sometimes carried in myoutboard tanks for snowmobiles, chainsaws whatever was the automotive fueland that was available on Merrill field Anchorage for A/C STCed for automotive fuel. I also flew ultralights and had a couple engine failures before figuring out 2 cycle engines are highly prone to lead fouling when you use 100LL or even 80/86 avgas.

I could if needed burn the autogas in the GO-480. A few times when AV gas was difficult to find out in the bush I did use some autofuel usually mixed 50/50 with avgas. I also tried to avoid high altitude and high performance useage with auofuel.

I will give ken Noe a call, maybe add to this.

Louis,

If I remember right, Ken (the guy you reference as Mr. Noe!) said it was around 30 pounds of steel that he removed off the cage of your airplane. I agree with Doug on this one, probably the best example in the fleet!

Factory Engineer Robert Casebeer

Doug, please refresh my memory.  Mr. Casebeer was working at the factory ?  And he was an engineer ?  And Mr. Brent was the engineer of the type certificate ?

Is it Mr. Casebeer that was this fine gentleman that did the hand work on the modified cowling and from who i bought the aluminum legs for my H800 ?  What was the airport he was based at ?  There was a 800 there in a hangar, very low time.

Another thing you can do is haul non-alcohol fuel for generators, chainsaws, boat motors, 4-wheelers or whatever in one or both of the outboard bladders

I use AVGAS for my honda generator, chainsaw, and before, the ski-doo.  Anything that did not have a catalytic filter.  Now the new ski-doo have catalytic filter, so i can't anymore.  The lead would clog the filter.

Avgaz is a little more difficult to start at cold temperature.  Less volatile than the winter auto gaz.
