Sorry, I haven't owned a 72 since about 1994 or so, I had it on a BTE Venture 60, I had dual aileron servos on it. The right aileron servo went crazy and it rolled into a concrete road on the Fort Belvoir Engineering proving grounds. You know how the Army builds roads, the 72 lost big time. I sent the 72 to William Robison for parts.

The RCM 60 is coming along well, the 60 twin fits it well, other than the mounting my only concession to that was to mount the elevator servo near the tail.

Hey guys, you could never guess who called me ! you could never guess who I just got off the phone with,

it was Hobbsy,
it was a great conversation. it's a funny thing to find that some one that lives so far a way from you has so much in common with you. I have to say we really didn't have enough time to talk more.

thank Dave! thanks for the call, it perked me up a bit.

Dave, are those "Thrust" brand mufflers or are those "Cherry Bomb" mufflers, it sure looks cool !!

Isn't that the truth. My hobby bench looks great every Sunday morning, by noon it's covered in tools and stuff again. I'm not even sure why I clean it up once a week, habit I guess.

Thanks Jim, it was a great conversion, yep those Turbo Headers do look great I figured, new plane, freshly rebuilt engine, what the heck. That WildCat 2/4 full synthetic has the most powerful dye in it you can buy.

Note the hardwood block below the fuse bottom, that's where the carb dictated that the nose gear bearing be located. There is 1/16th" clearance between the bearing block and the carb. As I write this I'm having a Yuengling Golden Pilsner. I like keeping my life fun.

That's how I find half of my tools, by cleaning up the work bench.

LMAO. Ok past three days I have been looking for my long bladed screwdriver. Cleaned off my benches in the process. I am sitting at the kitchen table where my laptop is, reading about clearing benches to find tools, look up and there it is, sitting under the TV. SMDH.

Glowgeek

Glad I could help acdii, you owe me one.

I don't know if it's obvious but the 60 twin is mounted as far left as is possible, I hate most left things, but the firewall is mounted 2 degrees right and 2 degrees down and magically the prop driver ends up laterally dead center of the fuse.

Lonnie, the prop shown is a Xoar 13 x 5, when I tach it you can work out a hp number.

Glowgeek

Sure thing Dave, be happy to. The 60T makes around .85 hp so anything over 9300 rpm would be a good number for the Xoar 13x5. Pitch speed at 9300 is right at 38 mph and static thrust is right at 7.4 lbs.

Oh boy
I hate when I don’t keep up with the page.

My fuel gets it’s color from the oil that’s added. Klots is red. The straight caster blends are straw colored.
but dye doesn’t effect running at all. I used to deliver fuel and people thought the red fuel was more powerful the the yellow green fuel you put in your truck. It is so hard to tell them it comes out of the same hose they just put in a thimble of red per 1000 gallons so the DOT can look to see if the farmer is putting in there pickups. ( red fuel has no tax).

And you all that have talked to Dave he is awesome to talked too.


still can’t wait to meet Gary.

I’m just curious. Been looking at those Saito 150’s. Some are labeled 150 and others 150S. Is there a difference? Also, some have metal throttle levers while the newer ones have plastic throttle levers. Newer, improved carb?

Glowgeek

150 info for you Quikturn

Interesting Glowgeek. So the S is an early high compression version. Is that desirable? Are the lower compression versions better mannered?

Glowgeek

Actually the early 150s was high compression. They made those for a few years, the later 150s was lower compression. Maybe Dave (Hobbsy) will jump in here and tell you about the manners of the early high compression 150s.

spoiler: prop chucker!

Captcrunch44

Hmmm
just got a new specimen in the mail. Nice looking 125GK. Will have to get it on the stand and run it so I can get all the oil out of it and see if I need to give a run through.

Jesse Open

I still have a HC 150. Presently on the Rascal 110. Pretty nice running engine overall. Taking it to the club swap and shop next Tuesday, along with the rest of the remaining Saitos and a large stockpile of parts.

Crunch, You will love that 125! They hand start real well, wet with a backflip.

Good morning all, the early high compression 150-S had 11.24 to 1 compression, not super high though, the early 80 had 15.5 to 1, both demanded a certain amount of respect. Don't get either rich or lean or your prop will end up at your neighbors, my 150 actually did that on a 30 degree day. Once you get the touch you'll love it. As Gary said the 150 is a sweet heart. Those high compression Saitos and a Fox Miracle plug are a perfect match. Although CH Ignition is a perfect match also. You're pretty much limited to 10% fuel on both. The carbs are all the same save for the arm. Supposedly the current spray bar is an up grade, I could never determine a difference.

A quote by w8ye, "The 150H deal came about from some INTERN girl working at Horizon Hobby advertising department saw a little "H" stamped on the top of the right lug. They've used the same advertising copy ever since."

Mike, if you hang on to the 125 I'll fix up a suitably sized velocity stack for it.

Gary, a funny lathe story, somehow I lost the Glow Head for my little red Irvine .25, so I decided to modify the Diesel Conversion head and put a glow plug in it. Naturally the conversion head is thicker to make room for the contra-piston travel. I chucked the head up perfectly so it did not wobble, proceeded to cut from the bottom up. When it got to the thickness I thought proper, I proudly took it out and got a shock. I had cut the head bolt holes off and all that was left was the larger relief holes for the bolt heads. I just stood back and grinned and ordered up some 1/5/16" aluminum bar to make a whole new head.

Captcrunch44

Yeah don’t plan to get rid of the 125.
I will find a airplane to put it in. ( do I smell another Hog) hmmmmm.

Jesse Open

Ouch! Not sure without seeing it, but you may be able to make some flanged bushings. Counterbore the the screw holes, set the bushings in place and pass the head screws thru the bushings. Just "thinking" in print. Make the bushings from steel though.
I really need to ship that box of goodies. I will toss in bar stock of different types and sizes.

That little "H" is how Horizon verifies an engine is one of theirs when doing warranty work.

I get dirty looks, or worse from the Norwegian Princess when I utter comments like "I smell a hog".

How about a Hog Bipe?
