Joe,
I would be interested what year they were added.

Culver General Discussion / Horizontal Stabilizer Strut
« on: July 01, 2014, 10:09:09 PM »
I have noticed that some Culver Cadets have horizontal stabilizer struts. Through what serial number were these installed? What changes, if any, were made to the stabilizer to eliminate the need for these.

Aircraft For Sale / Re: Culver V x2 eBay

I don't recall hearing any parts in common with the Cadet. I am unfamiliar with the fuel injected version of the C-85 Continental.

Aircraft For Sale / Culver V x2 eBay
« on: June 30, 2014, 07:29:09 PM »
There is an auction for a Culver V (two in one auction) on eBay with a starting bid asking $5,000. It looks like multiple spares in addition to the basic airframes. If there was only time and money for every potential aircraft project.

The two project aircraft are also for sale on Barnstormers. They are being sold by the Port Townsend Aero Museum.

Maintenance and Repair / Re: Placing Cadet on stands
« on: June 30, 2014, 05:36:25 PM »
Knowing what I know now I will modify the wood blocks and the RV jacks. These will be placed as located in Service Memo 19 Figure 5, as a secondary support point. The aircraft is still jacked up by the station 91 jacking points as mentioned above. I'm not totally sure these secondary supports are needed, but I do find it provided some secondary support that doesn't seem to hurt. Peace of mind from all the weight being carried by the station 91 jacking points.

I am attaching a few photos of my Culver Cadet up on jacks for a gear swing.
This Culver has tiedown and jacking points on the metal wing truss as indicated on page 16 of the PQ-8A Manual Figure 22.
The jacking point for the PQ-8A jacking is shown at station 91.

The engine hoist was merely attached as a backup to the 60 lbs. of sandbags on either side of the root of the horizontal stabilizer.
I really didn't want to experience the Culver tilting forward. There were also RV stabilizing jacks added with oak wood blocks and rubber facing on the spar near the gear as an added stabilizing point. I now think this was unnecessary.

There is wood blocking shown in Service Memo 19 Figure 5, at the fuselage and wing juncture. This seems like a preferable secondary point as opposed to my RV jack location in these photos. I have added that figure below.

Modifications / Culver Cadet Gear Warning Horn and Circuit
« on: June 28, 2014, 08:44:56 PM »
My Culver Cadet has a gear warning horn activated my retarding the throttle and the gear not down. This seems to have been done a fair number of times from what I gather, even if not entirely common. I am attaching attaching a photo of the microswitch, with and stop on the throttle cable, and the circuit schematic documentation from my aircraft.

Maintenance and Repair / Re: SCAT duct to nowhere?
« on: June 28, 2014, 08:17:41 PM »
Hello Bill,
I have looked at the revised setup done in the eighties with the retrofitted Continental C-85-12F. There is an aluminum box under the engine, with air directed from the screen openings under the prop on the front cowl. This has taken the place of the original opening you mentioned. There are also SCAT connections off of this box at the front. It appears that, over time, these SCAT tubes were pulled during annuals and not redirected well toward the oil reservoir. This is not surprising as the aircraft was very minimally flown, and more a personal museum exhibit than an actively flown aircraft.
There is nothing wrong with that but it led to these SCAT hoses not being properly done as the collection went from a full time mechanic, that passed away, to another mechanic that did enough to keep the collection functionally airworthy. The owner was no longer actively flying the collection.

My mechanic and I discovered this when pulling the lower cowl for a 25 hour inspection that involved cleaning the plugs and replacing the Brackett air filter.
The SCAT ducts are now properly directed. The post maintenance flight today now has oil temperatures substantially lower on an 80F day, somewhere in the area of at least 10-15F, or more, lower.

Maintenance and Repair / SCAT duct to nowhere?
« on: June 26, 2014, 09:53:24 PM »
Hello,
Does someone have any insight as to what these SCAT ducts originally did?
I had my lower cowl off today for the first time to clean and rotate plugs.
There are screen openings under the spinner that lead to the SCAT ducts to nowhere.
The mechanic wondered if it was some type of cooling air toward the oil reservoir.
I just acquired this Culver Cadet, that was originally an LFA, last September.
The aircraft now has a Continental C-85-12F after having two different Franklin engines prior to
this engine being installed in 1983. The lower cowl has welded aluminum areas where
the Franklin exhaust would have been (slightly blurry as my camera had been manual mode for another photo).

Parts Wanted / Re: Landing gear leaf spring
« on: June 07, 2014, 12:05:45 AM »
At one time the Antique Aircraft Association had a small stock of Helton Lark springs. I understood these would work for the Cadet. This was some 13 years ago and I don't know if they still have any. I have my own set as spares for my Cadet, but no extras.

Culver General Discussion / Culver Cadet Original Instrument Panel Photos
« on: December 28, 2013, 10:05:22 PM »
Hello,
Would someone have photos of the original Culver Cadet instrument panel?
I'm trying to put the details together for reworking my instrument panel to
the orginal factory configuration.

Maintenance and Repair / Re: Primer-Original on the Culver Cadet
« on: November 23, 2013, 06:15:52 PM »
I have purchased an old Imperial Brass and a Lunkenheimer primer that I will need to have nickel plated. The primers are appropriate for the production date of February 1942. I don't know if these are original to the Culver Cadets, but they were certainly used on other aircraft during this time. This is part of a long range change to the panel several years down the road.

Maintenance and Repair / Primer-Original on the Culver Cadet
« on: November 02, 2013, 07:27:11 PM »
I have a C85-12F that was installed in my Culver LFA. The primer was completely removed at some point. What manufacturer made the original primer? A mixture control, installed in the original primer location, has been disconnected. The carburetor is a Stromburg NAS3A1. Is there a thought as to why the mixture was disconnected? I understand that below about 5,000 feet the mixture is really not necessary. I fly over mountains above 5,000 feet.
