Hi guys,
Time for a new question.
My Pulsar 1 tail dragger kit has the original composite main gear.
It looks to be in good condition, however I wonder if there have been any modifications
required, or issues with these in service?
Are there still many Pulsars out there flying with the original composite main
gear?
Matt.

Some of us added a wrap of fiberglass or carbon fiber around the lower part of
the leg. I used carbon fiber - about 1/2" wide wrapped around the very end of
the leg and another just above the where the axle mounts. There were small cracks
developing and the wraps stopped that. That was 10 years ago - no more problems
with that area. However, I have also had problems with the bolt holes
wearing where the gear mounts to the seat back and to the gusset. Once the holes
are worn you get a popping sound when turning. I have not come up with a good
permanent fix for that yet. So far I just keep them tight, but a repair in
that area is in the future.

My gear is composite - 20 years old and was not reinforced. It broke during a soft
landing so I chose a repair which has taken 4 months and cost a fortune (insurance
claim). I should have gone for the alu leg from Grove. They made a special
for lighter models. Mine is 1060lbs MTOW.

Kit #390 after twelve years is still flying with the original foam filled
composite gear. It has seen about 1,500 smooth landings and 500 teeth
jarers. (( give or take a few.))
About eight years ago a crack developed that ran two inches up from the
very bottom on one side. The wheel mounting plate places two mounting bolts
either side of the crack. that keeps the crack from spreading open.. The
crack has never gone any farther up the gear so I didn't do anything about
it and have long since stopped worrying about it.
After twelve years the gear has developed a little permanent spread. The
wheels no longer sit exactly straight up and down. Close but not exactly.
HEY - - - - we all develop a little spread with age. I expect to go on for
a few more years and I expect my gear to do the same.

The very early main gears had problems and a heavier core ? was used which
improved the gear. Later a mod came out because of splitting at the bolt
holes for the slub axles, this envolved wrapping carbon fibre around the
lower 5 or 6" where the bolts went through to stop the splitting. ( for
Bernard )

I did ask the repairer (Roger Targett, a composite specialist) to wrap my repaired
leg and I mentioned the norm was carbon - he seemed to take the view that
glass was more appropriate. He has wrapped the 2" above and below the radius i.e.
a 4" sock. He does this on the Extra to stop the leg delaminating. Not sure
about the science but I am happy to take his advice.

There was also a mod to the Glass gear by Skystar for the Pulsar III. It
added carbon fiber to the gear legs to stiffen the gear legs. They have a
tendency to shimmy when landing faster than normal.

One of the rear mounting bolts for my taidragger main gear has broken.
All the taildragger supplement manual says is 5/16 bolt (countersunk).
Anybody know what this bolt might be and how to find one? The broken
bolt is a phillips head about 1 1/2 " long with a 7/8 inch bare shank.
Thanks
