LOL It takes more brains to do a good weld than it does to push paper around!

This about sums up sports for me.

Good news. Ordered a Saito 182 yesterday from Horizon. Just delivered at noon today. Maybe pics tonight!

Should sound great on 14% nitromethane / 14% oil (2% castor, of course). With a pair of Enya glow plugs providing the ignition.

Got any more pics of that Edge from the clean side?

The hole diameter in the 16 x 8 is a tight 10mm, I knocked the Tee handle out of this reamer and it cleaned it up perfectly by placing the reamer in my drill press in low speed..

A Master Airscrew Maple 18 x 6 and a Graupner G-Sonic 16 x 8, 2050 rpm difference, props matter.
The two different props.

In the background is an h9 taylorcraft with an fa182td also deccy with fa82


Dave have you had a rattle can of paint out and painted up an apc prop then re stickered it looks alright for a graupner,i hate those old hard boiled grey one's.

Jesse as a kid i hung around the local airfield pulling planes out of the hanger to wash them and then over to the flight line.All the hangers had birds in them and washing poop off was normal.If the bird had been sitting on the plane then it was a small area to clean,if the bird was up in the hanger rafters the poop circle could be huge.Every now and again one of the pilots would take me for a ride,even let me fly a bit so long as we wer'nt close to anything.

ps i still think natural pidgeon poo is the ultimate in realistic scale detailing

A 12 x 8. my Fox .74 Diesel would turn that at 9,400.
Those old gray Graupners are my favorite, I still have a bunch of them. They have nice wide blades and look good.

Default Satio 80 fuel issue

I have a satio four stroke 80. The engine starts up no problem. After startup and while it is running fuel constantly comes
out of the exhaust more than usual. I adjust the mixture but that doesn’t help. It a lot more fuel than exhaust coming out.
any ideas? Thanks

What fuel, what prop, what glow plug, give us everything that would effect the the way it runs, How many turns out from closed is the HS needle, it should be less than two turns. Thanks

Hobbsy, what is the correct setting for the slow speed needle on an old .80? Have ylu ever run a 14- prop on one?

Thanks,

Mike

Initial setting is with the metal throttle arm is even with the throttle arm face, if plastic about 1/16" below the face. It's easiest to peak the HS needle and leave it peaked while you set the LS needle. You can see that this 1980s .80 is well down inside the barrel.

Do you still have the sliding choke plate in place ?

I removed all of mine because they would close by them selves on occasion.

Thanks Hobbsy! I have an old second hand.80 I need to get going. I'm running 10% Nitro Blended oil fuel I don't mind a little clean up. I like a little castor in my fuel for a little added protection and 10% seems to work good for my 2 and 4 cycle engines. If I ever get around to building something for my ST S3000 I'll probably start stocking some 0% or 5% Nitro fuel in addition to the 10%. Those big Super Tigres do't seem to like much Nitro.

LOL


70 degrees F. Here today. weather looks great.

Somebody mentioned prop reamers It has been very difficult to find quality prop reamers from the hobby industry lately. I have been using precision ground industrial machine reamers as a basis for prop reamers. OD grind a suitable pilot then resharpen the cutting edges.
Make them up as needed but these three get the most use by far.

I use an old tried and tapered tubing reamer. Its older than me and still sharp. I start from the back side of the hub and ream and test and ream and test util I get a tight fit. It has never failed me.

I used those very early on. I do prefer at least 1/3 of the hub bore to make a close parallel fit with the shaft.

The piloted reamer also tends by nature to more closely follow the original bore.

Just personal referrence.

I don't know, I find reaming quite boring.

For certain,
Not nearly as exciting as a mis tracking propeller!






Good pun too
