Every C3 clearanced front bearing I've tried from RCb and Boca have leaked after an hour of run time. Makes quite a mess all over the plane. Nothing but boca standard clearanced bearings for 4 strokes from now on, the last three sets have not leaked.

I may have a black 50 case, should be the same, if not I hope someone will say. I'll post a picture if I have one.

Pete,
No love of tools here, I like to use them but certainly no love between us

I do have a new 65 case and a welded 56 case with good holes in the lugs. One corner was clipped and repaired by welding.

The 56 cylinder fits down into the crankcase, but I didn't check to see if the bottom of the piston could pass down through. I bet it won't as you alluded to. The 50 crankcase is mechanically sound but urgly..

guy, I need some input here, what do you think will look batter ?

so I am back working on my 4-Star 60, I bought some yellow/black checkered covering for the top of the wing, I bought it with 2 inch squares, but now that I received it I think the squares are too large, I have no problem sending it back, so what do you think would look better 2 inch squares or 1 inch squares ??

like I said, the whole top of the wing will be covered, the span is 71 inches.

BTW, because I want the plane to look like a racing plane designed in the 1930s I am going to round the tips of the wing.

oops, I am putting my Saito 100 Twin on it and I have the new 4 Star 64 cowl, so the heads on the engine will be sticking out the side of the cowl, I checked it and the exhaust will be on the outside of the cowl,,,, slick

The pushrods are on the way, probably arrive Tuesday. Just don't let anybody call you Mr. Magoo.

Thanks Jim, it worked like a charm.

Crunch is right the 56 piston can't pass down into the 50 crankcase the little bit that it needs to. Well see if Lonnie wants to go to that trouble.

Dave, Gary, thanks for your offers but this engine is for resale. I've tried to sell it at a couple of swap meets and flyins but potential buyers seem to be more concerned about flaws in appearance than performance. They pick it up and see the filed out mounting holes which is usually followed by a comment like "oooh" or "hmmm". No one has asked how it runs. I'll find a pretty case some day.

Rain, rain go away!

Got my hot rod fa82b back together this morning just in time to get rained out. The compression feels very strong at 11.75 :1.

Got to the field at 8AM. Nobody their but the Norwegian Princess and myself until noon. Burned nearly a gallon thru the tired old FA-82 in its original ride, the Toledo Special. Left there early as the lawn dart foamy electrics usually show up around two in their little pink pajamas.

The old Toledo looks a bit long in tooth but still a good ride!


The "Oil Ejector" is back on the muffy. Dumps the vent oil into the exhaust stream.

Interesting way to eject oil. Does it help much?

Gary,,
1) do you use a "one-way valve" when dumping the vent oil in the muffler ??

2) I agree, you got to keep a way from those pink pajamas

guys, I think this was talked about before for flight (but I don't remember the outcome of the discussion), but here I was thing about doing this just for the brake-in on my Saito 100 and 115, this was about using a small header tank filled with oil hooked up to the back plate, of course it would involve using 2 "one way valves"

I would think this would be good for the connecting rod seating,
to add, 2-stroke oil (for alcohol) would be best to use encase some oil sneaks by the ring gap.

side note, I have to buy oil any way, I have a gallon of Super Tartan fuel/ strait methanol with 6% Castro that I want to use for the first couple brake in tanks for my ABC HP 61 and K&B 100 (0% Nitro is recommended for the brake in of my HP)

what's the skinny of your thoughts ??

Jim

Jim,

The oil isn't actually getting dumped into the muffler. That brass tube passes through from front to back . The plane used to get very oily on the bottom and up the port side. Now the sides both stay clean and only the bottom gets slimed.

Not sure what you were trying to do with the break in but with two check valves, yes you can inject additional oil to a running engine. You still need to allow air in as well.
