Culver General Discussion / Re: New Cuver Dart Owner
« on: September 11, 2019, 07:23:50 PM »
Congratulations Kevin,  I have over 1700 hours in the original Monocoupe Model "G" predecessor to the Dart and pictured on this site.  It is powered by a Lyc 150 and is a great flying airplane.   Post some pictures of your project.    Tim

Parts For Sale / Eisemann Mag Coil
« on: January 04, 2019, 12:04:15 PM »
Hi everyone,  I had my Eisemann  magnetos overhauled recently but after a couple of hours the coil on one of them has failed.  Does anyone have a coil they would be willing to part with.    Tim

Maintenance and Repair / Re: Tailgroup alignment
« on: December 17, 2018, 07:54:04 PM »
Keith,  the first thing I did was blocked up the fuselage with the top longeron level.  I purchased five digital levels from Home Depot and used double face tape to attach the levels to the bottom of the wings at the
 roots and at the tips.  This showed me that the wings were one degree different.  It also showed that the individual wing had some twist in them.

I decided to lower the right wing 1/2 degree to start.  To accomplish this I removed the rear spar fittings on the right side. Calculated the amount that the rear spar had to move down to change the incidence.  Next step was to machine a bushing with the inside diamieter of the spar bolt.  The spar fitting were drilled slightly over size.  I elongated the holes in the spar fitting to get the proper distance in the spar plates and welded the bushings in.

That is the process that I used.  When this Cadet was restored the top longerons were replaced at the rear of the fuselage due to rot in that area.   

Maintenance and Repair / Tailgroup alignment
« on: December 10, 2018, 05:43:41 PM »
I have been fussing with the Cadet to get it as straight as possible.  I knew that the tail was tilted with the left side being lower than the right in relation to the wing.  Previously I had lower the right wing by 1/2 degree to get the incidence the same on both wings to level the wings in flight.  That help some but did not totally cure the problem.  As a long time RC pattern flyer I am really aware of how much better an airplane flies if it is straight.  Meaning that I am still unhappy with the trim of the airplane.  It turns out that the horizontal stab is not only tilted but also angled.  The right side is 1 inch closer to the trailing edge of the wing than the left.  The only solution that I have come up with is to reset the tail on the longerons.  To do this would require drilling new holes in the longerons.  Anyone have a better ideas?   Tim

Parts Wanted / Culver V gearbox for landing gear retraction
« on: September 06, 2018, 07:28:04 PM »
I am looking for the gear box used in the Culver V to retract the landing gear.  It may also have a motor attached.  I need just the gear box but would take both.   Thanks,  Tim

Maintenance and Repair / Intake leaks
« on: July 24, 2018, 07:10:08 PM »
Has anyone been having recurring leaks around the crankcase end of the intake tube on the Franklin engine?  Seem like about every 10 to 15 hours the o-ring type seals start leaking and need replaced.

Do you have a part number?  I have a carburetor that is suppose to be for the 80 hp Franklin.  It still has the tag on it.    Tim

Maintenance and Repair / Re: Aileron freeplay
« on: November 21, 2016, 11:51:46 AM »
Thanks Keith,  I agree way too much movement.  I removed the entire aileron push rod system including bellcranks.  All joints had bushing with a little play.  Constructed new push rods using rod ends.  I will post picture soon.  I have not had time to install them yet but will l let everyone know how it turns out.   Tim

Maintenance and Repair / Aileron freeplay
« on: October 14, 2016, 03:07:14 PM »
I have been working on improving a number of minor issues on N 41726, including root fairings, Aeromatic prop, landing gear retraction and fit and general sealing.  After the installation of the Aeromatic I became concerned about slop in the Aileron control loop.  I had noticed that one of the ailerons was flying higher than the trailing edge of the wing.  I fixed the left one centered on the wing and was able to moved the right control surface 3 to 4 inches without any resistance.  This strikes me as way to much free play in the system.  There are 8 connection in the loop from the left control horn to the right, each one has some play between the bolts and the bushing.  Has anyone address this issue with a high time Cadet?  If so what was the solution?  Does anyone have knowledge of a Cadet experiencing flutter of the ailerons?  I am planning to replace all the fitting in the system but would like to know what is acceptable as far as the maximum amount of free play.  Tim

Bill,  I have a Marvel Schebler MA-3 carb.  It does not have a tag but the numbers stamped on it are 17865, 10-2153.  I can send pictures if you are interested.   Tim

Modifications / Root fairings revisited
« on: July 25, 2016, 01:13:34 PM »
I have finally finished installing new root fairing on the Cadet.  I have attached several pictures.  The forward portion is fiberglass.  The rear is a stock Mooney M-20 root fairing.   Tim
