OK, how many points are on the Flying Crown logo? This was an important issue in one episode that I recall. SKy King trivia time!!

Re: Bumps and Notches

I have the bumps but the regular plugs, regular wires, and Eiseman mags. It either had a sheilded system in a past life or when last covered and painted the bumps were added just because. Can the sheilded plugs, and sheilded wires be used with the Eiseman to get rid of some of the static. I had thought I wanted the Slick conversion but with right prime, about four blades mags off, and she catches the first blade with mags on. The static seems to be the worst in the innercom and not a serious problem but really annoying.

Re: Bumps and Notches

I had Eisemann mags which I replaced for two reasons: the coils were getting bad when hot, making hot starts a big problem, and ignition noise rendered intercom and VHF communications difficult to useless. I was not able to find any kind of distributor cap for the Eisemanns that would accomodate shielded plug wires. Maybe someone here might know how to hook up shielded wires to an Eisemann mag distrbutor cap. All the local A&P's and gurus told me it wasn't possible. I was also told replacement Eisemann coils were new old stock, manufactured a long time ago, as much as 50 years (?!?), and there was a large chance a "new" coil wouldn't be much better than an old one. So I traded for new Slicks, which have been just great.

Re: Bumps and Notches

There is no shielding in eisemann AM4 mags there is in eisemann LA 4 mags but they are a bigger mag, eisemann mags are a good mag , I have heard that from many people Arn Air in Iowa services them, If you want no noise in radio communication I think you will have to change to a sheilded mag, like Bendix or Slick with the harness and plugs, lots of discussion on this topic.

Re: Bumps and Notches

Lynn,
If you are getting noise on the intercom and not the radio you have an unshielded lead or your intercom is too close to a radiating wire. Check all of the wires and plugs. If you move the plug and it crackles in the headset clean up the contacts. If that doesn't work try moving the intercom box and grounding it to the tubes.
It may take some looking, but it sure is nice when all the noise disappears!
Worst case you might have to put a shielded box around the intercom box.

Walt,
Hope it helps. My regular email is hjarrett 2 at cox dot net. I have a feeling a lot of people won't have clue what we are talking about. ;-)

Re: Bumps and Notches

Yes I probably should have sent that message privately

Re: Bumps and Notches

The innercom box would be the first to work with. It is now floating around on the glare sheild and the wires to hook it to the radio are wrapped around the braces behind the windsheild. The radio is a Microaire running off a rechargeable battery pack. The antenna is on the top center behind the baggage area and it is a fiberglass aircraft antenna which is usually better than the rod whip. I know I need to clean this up, the weather has been too cold to hang out in the hanger and when it is decent I have been out playing, this is still a new toy to me. I am a ham operator and will wade into it. As far as the sheilded ignition wires it sounds like back to the original plan, as long as the Eisemans work spend the money on things like gas, and things that float to the top of the to do list. At least it has the bumps so when the time comes to put on a Slick conversion it should be a pretty simple install, just a sharp jolt to the RH hip pocket.

Re: Bumps and Notches

Lyn,
If you have the wires wrapped around the tubes you just created a great ferrite core inductor. I would say it's a miracle your intercom is working at all!
I have a feeling your problems are about to all go away.

Re: Bumps and Notches

Actually Hank it could be a high frequency filter, or a low frequency (transformer like) pickup. Choose one. LOL

One of the things I was worried about cutting a notch in the nose bowl was the possibility of creating a stress riser and a crack later. Was kicking around how to strengthen the cutout. Edit: or how to avoid cutting a notch.

Speaking of Sky King. A few weeks ago I was drooling over a straight-tailed C-310 for sale very cheap near here. I love that plane, but I think it had a kludge job fuel injection system installed. My local engine shop owner cooled me down on that one.

Re: Bumps and Notches

Ah memories; I got to fly a straight tail 310 about 45 years ago and gained 500' with every turn. I had, maybe 20 hours total at that time, all in a Piper Colt and if you did not haul back on the stick (wheel) with every turn you lost altitude. I still like the looks of the 310, I guess I am showing my age. Larry

Re: Bumps and Notches

I don't know about age, I just think it is good aesthetic taste. You see a really clean 310 sitting on the tarmac and it just looks really sleek and fast. I think it is one of a very few planes that a swept back tail looks appropriate and streamlined on; that is, the balance of the design matches the swept tail. I'm still partial to the straight-tailed version though.

I just figured out how to make the cutout in the front bowl nice and neat. Use a hole punch, what we used as a chassis punch, now used mostly for instrument holes? My friend in the hangar next to me has a set.

Re: Bumps and Notches

I flew in a straight tail 310 two times. It WAS a good looking airplane and fun to fly although I was far from expert. I thought it was better looking than later models also. Very stable and smooth, easy to land. I have Eisman mags on my T-CRAFT and once I got the prime-pull thru down pat it fires right up on the first pull (no more than three). I'm told parts are readily available from Fresno and to keep them as the new Slicks are cheaply built. True? JC
