Plane suggestion for an old .19 Torpedo Green Head
« on: August 03, 2015, 07:04:05 PM »
I have an old .19 Green head I found in storage. I believe that a friend gave it to me long ago.
If I can get it to run well, what would be a good plane, either ARF, ARC or even a kit, to put it in.
I have no idea what amount of power that something like this will make, although I would guess it would be less than a current .15.
It certainly is a "tall" motor for its size. I'd guess it has a long con rod and or a long stroke for the displacement. Maybe it turns a decent diameter prop?

Thanks in advance. :)

Is the .19 a little big for the ringmaster jr wing at 200 squares? I know it says .09-.19, but 200" seems like a small plane, and maybe the engine would be a bit heavy?

Yes, the Torp .19 is way too much power for the Ringmaster Jr.  Forget that one!

Trade/sell it to a Nos FF guy. It's perfect for a RamRod or a Zeek! Or build a FF, perfect between glider rounds at Perris!

The K&B 19 Green Head is a reasonably powerful engine.  It's actually one of the most powerful for it's size in the era it was made and used.  Only the Veco 19 rivaled it.  I had a highly reworked one with a different head and piston in the mid 50's  in a Dizzy Boy and it was very fast for the time 7-6 prop on 40% nitro, several runs on 60 ft lines over 135 mph (two lines).  Certainly not a record breaker but respectable in 1957.

I saw a couple flying S1 Ringmasters very respectably also in about the same time frame.  Excellent engine for nostalgia FF as mentioned above.  I was pretty much Combat, Rat Race and Speed in those days so I never actually used one in a stunt type airplane.  The re is however a possibility of a kit being made by Mike Griffin of the Little Thunderbird that it would be perfect for.  I think it's about 475 SQ in.

Thanks Randy.
I'll get the thing on the test bench with "my mechanic" and see how she runs. I can decide from there.
I'm thinking the full size S-1 might be a good bet if Mike doesn't get the little T bird kit going. He's got lots of irons in the fire!
Thanks again.

I thought the flite streak had issues with the fuse falling apart at the nose? Maybe that's a myth or been fixed, but I swear I read that somewhere....

So, fly it until it falls apart, and then patch it up and fly it some more!

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

Even if it takes a little more time, I shoot for durability before putting something in service. How much truth in the breaking nose issue? Anyone know?

I broke the nose off mine on the first crash. Nothing about 4 oz. of epoxy can't cure.

 any profile that dosnt have motormounts going past the leading edge of the wing can snap the front off ,even the Ringmaster ,a little glass cloth and epoxy will stiffen it up

Yeah, good catch Mike...your post made me go to the shop and dig out some old records from those times...yes believe it or not I used to keep excellent recorda of nearly each flight (especially in Speed) and it said there were a plethora of props tried but the best times were with mofified tornado 7-7 cut and reshaped to 6.1-7.   Hey forgive the error it was 58 years ago.  I have trouble remembering what I had for breakfast today!!!

Yeah...a couple of years after that I had a monoline Dizzy Boy with a Dooling 29 that actually set the record in B at 149.6 for all of one day.  Shelton and Harris broke it at 157.2 with an engine they built on a McCoy 29 crankcase.  They used 70% Nitro.  I tried it in the Dooling and broke the crank pin and didn't get an official...sounded like 160 but it only ended up with me holding my beautiful Dooling and feeling like crying.  A lot of groceries bagged and floors scrubbed went into buying that engine!  Rod went through the bottom side of the case and the piston crumbled and stuck in the exhaust port...uhhh the head was OK... HB~>  Comes under the heading of live and learn I guess.  A good friend and mentor Byron Merriweather warned me not to run more than 40% in the Dooling but what the Hexx...I never was one to take good advice!  :'(

VECO Tom-Tom or Tomahawk.
In the 50s, I had both, powered by the K&B 19.
I did everything I could to build them extremely light and it paid off - they really flew well.

Do you plan to run some kind of a muffler? If not, then personally, I'd pass on the profiles, unless your launch assistant likes a lot of noise and castor in the face...   :P

I tortured poor Paul Sequira with my Banshee and GH 35 when I came back to flying C/L back in the late 90's. He was a good sport, but Paul is a rare find in a very good friend. He didn't complain back then, but somehow it came up in conversation years later and we laugh about it to this day.

Randy, I wonder how many of us Pappy Meriwether helped back in the day.  Only seen him fly a model once and that was a balloon pop event.   What was funny was after he popped all the balloons some had to go get the handle so he could pull his pants back up.  Thank goodness no one had a camera at the time.  Was very fortunate enough to see him again before he left us.  He knew who you was as soon as I showed him the picture ofyou with your plane.  He supplied me with the McCoy Redhead .60 for carrier I won so many trophies with.  Still have the engine.  So many stories I could relate about him and the boys.

On a profile ... mount the GH on the inboard side.  Exhaust will be facing down and needle up.

Recently did this, and it worked and flew great!

I thought about suggesting that, but then thought about the amount of tip weight it would take to offset all that for a good clean corner, plus whatever doing that does to the over all weight... I guess if it works, it works... depending on his goals for the plane.

Chris - be careful in fitting a muffler to the Green Head 19. We tried one, Tatone as I recall, and the engine tended to overheat.
You might want to try one of the lighter modern mufflers that allow for more expansion. Possibly one from an OS 25 or similar might work.
You'll probably have to fabricate a strap-on adapter.
