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

Modifications / Root fairings revisited

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

Maintenance and Repair / Sparkplugs
« on: September 09, 2015, 05:22:28 PM »
I was noticing that my Franklin powered Cadet seem to be down on power.  I had Champion REM 38s installed with 160 hours on them.  Mogas for fuel.  After checking mag timing and verifying that the throttle was opening all the way I changed plug to C10 S.  The power is back and the engine is running smoother.  I would like to hear if anyone has any opinions as to the expected life expectancy of sparkplugs in the Franklin engine.   Thanks, Tim

Culver General Discussion / Oil pressure on Franklin 90
« on: July 30, 2015, 08:00:13 PM »
Hi everyone,  My daughters Cadet is powered with a Franklin 4ac-199.  It has 157 hours since MOH by Winfield Aviation in New York and runs really well.  The issue I am having is low oil pressure.  It shows 22 lbs at startup and increases to about 25 lbs as the throttle in increased.  As the temp. reaches 160 degrees it falls to about 18 lbs.  and stays there.   I have had the oil pan pulled and check the screen.  No debris of any kind.  Replaced the oil pump gears, plunger and spring.  Changed oil to Aeroshell W100 a little better but still under 22 lbs at idle.  I replaced the gauge prior to all of the above to make sure the gauge wasn't at fault.  I would like to hear from anyone that has similar issues and if they were able to cure them.   Thanks, Tim

Culver General Discussion / beech roby prop

Anyone currently using Beech Roby prop?   I have one in very good condition that I would like to trade for Aeromatic for Franklin powered Cadet.   Tim

Culver General Discussion / Land gear hanging down while flying
« on: August 31, 2012, 02:33:13 PM »
Hi evryone,   Mark Penner stopped by Wendesday to pick up my uncompleted Cadet project.  After loading it in his truck  I decided to check him out in my daughters Cadet purchased from Carl Baggett a couple years ago.   We jack-up the airplane and Mark cycle the gear a couple of time to get familiar with it.   I checked the gear doors while the wheels were up in the wells and they seem to be closed good and tight.  Took the plane off the jacks and sent Mark on his way.   It was obvious that Mark is an excellent pilot.   Mark flew around,  did a couple of touch and goes and landed.  A little later Mark again flew the Cadet in formation with me flying the model G Monocoupe, ( now know as the Culver Dart).  Mark had mentioned that he thought the right gear was hanging out a little.  I looked and it was not closed tight as it had been on the jacks.  I asked Mark to try rotating the wheel a little to get the last click.  He tried but the gear was still hanging out a little.   Do any of you have a fix for this?     Tim

Modifications / Franklin engines
« on: February 23, 2012, 12:00:21 PM »
Both my Cadets have the Franklin 90hp in them.  I have a brand new in the crate Franklin 0-235 of 130 hp.  It appears that it would bolt in with out much modification.  Has anyone done this?   Any thoughts if the airframe can handle the extra power?  I believe that there would be no weight increase over the stock 90hp.     Tim
