Veco .19
« on: July 15, 2013, 02:15:21 PM »

I've had a Veco .19 from RJL Engines for some time.  It came without instructions.  I assume this is a replica.  Last week I happened upon an old Veco with a very nice, light, strap-on muffler, making the RJL engine practical for stunt.  Does anyone know if this engine should be broken in the old way, with rich running in the beginning, or if modern stunt-speed break-in is best?  Also, does anyone know what prop David uses on his Veco .19 Ringmaster? 

Thanks,

Hi Kim,

It is still a steel liner/Iron piston so pretty much use the "old" break in method.

I have used a 10X4 prop, and I believe that is what is used on David's.  Without a muffler, they are pretty loud!  But running in a wet 2 they will pull most .35 sized models fairly well.  A favorite back in the old WAM "A" stunt class.

Thanks, Bill.  Yeah, I remember the SIG Banshee/Veco .19 as a popular combination back in the heyday of WAM.  I missed most of that party--a contest almost every weekend, sometimes more than one, a zillion events for the different engine classes.  "A" stunt faded, but has recently been revived around here as 25 Stunt, as you may know, which I hear is very popular.  My health has prevented contest-going for the last couple years, but maybe one of these days...

Flying at Gilroy, CA High School is strictly mufflers-only.  We had an old Brodak K&B .40 with a flow-thru muffler (remember those), or should I say "muffler-like object" make one flight only recently.  We have to protect what fields we have left.  We received noise complaints while flying during an athletic event this is held infrequently, even though we were some distance away.  Our fearless leader, Larry Fernandez, apologized to the organizers for the inconvenience and we cheerfully packed up for the day.  They were very nice about it and the result was amicable.  Another time years ago an irate baseball coach went postal on us and demanded that Larry, who was flying his PA plane at the time, crash his plane if necessary to stop the flight.  That guy was seriously scary.  I was afraid it was going to turn violent.  Larry ran the tank out, landed, and took the coach aside.  A few minutes with Larry and he went away a happy camper.  Larry's cred as an aspiring semi-pro pitcher in his youth didn't hurt, but the man really has the touch.  If he's that good with women, welllll......maybe he took lessons from Jeff Anderson.   LL~

Mine wanted 30 % castor for the first few litres .

Was going nicely running in , so fitted to twin @ 23% and turned into a wet rag .
Back at the shed brewed some 30% oil fuel and straight back on song .


10% nitros good.
15%s better .
20%s best .

And made a blue and had a bit of fuel in the Nitro once . By Golly . Gives the tourque .

ONCE its run in . though .

Matt,

I'm curious what plane you're flying with the Veco?  Weight?  Prop?  Muffled or loud?

Thanks.

   I think that is probably the right prop. The first time David and I did it in modern times, it was on Ted's Ringmaster. We didn't know what prop to use, so we got a 10-5 from the on-field hobby shop. The lap times were something in the low 3 second range. And of course this was during the first round of a contest and it was the first time either of us had flown the airplane. Second round we got a 10-4 and that was a lot less crazy and seemed like slow motion even though I think it was around 4 flat. David and I got so focused on beating each other, Chris Cox and his McCoy 35 Barnstormer, I think, beat us both because at the speeds we were running, neither of us had the guts to get the intersections on the 8's exactly vertical.

Mine needed a lot of running-in (and probably still has a little way to go). I was informed (by a usually very reliable source) that the large transfer port allows a slight amount of piston rock, causing a bit of metal to be nipped off during initial running - hence the long break-in time.

It's also extremely loud.  Mine is a K&B one without provision for the bar across the exhaust that the muffler attaches to.  Fortunately I found that an Enya .15/.20 muffler will strap on with a bit of minor attention.  Should be a nice engine when I get around to flying it in something.

What venturi and needle valve assembly works well for a Ringmaster sized airplane?  Is stock as good as any or is there something better?  I've searched and, although there are numerous references to using it in Ringmasters, etc., I've not been able to find any comments on setup.

HI Gary,

The stock set up is all I have ever seen used.

" I'm curious what plane you're flying with the Veco?  Weight?  Prop?  Muffled or loud? ".

By Golly , Bill . Youve seen it in pictures at least fifty Times .  LL~ S?P %^@ ( just kidding ) .



Now were going to engaguge in some SERIOUS Name dropping , here .  S?P

Picture above is the renouned Team Race World Champion Mr Potter , and Mr Potter Senior . overlooking & superviseing , and playing with a Camera
after doing a not to bad job of lauching all the things . Unfortunated TWO Bottles of NITRO & ONe of Methanol . Not the Two of Methanol & one of Nitro Id presumed . And even took a whiff to check . Didnt screw any of the engines , OS , Veco & Fox . though the Plugs were Black , after .
Mustve been 65 % . One should be a trifle cautious about wasteing the Nitro , Me Suspects .

ANYWAY . waas running a waisted & a unwaisted spraybar in a Std & a overbored intake , for some time . Has Std both now in both .


One Engines from Dave Bolton, He won Combat ( S.M.A.E. rules ) in N.Z. with one of the three he then had . ( Its MINE Now . ), around 76 . Other was N.i.B. K&B Veco c/l
Ive a unused third r/c with the case shorter at the intake as all the r/c are .

SO , First Flights were unmuffled .



The notorious Bryce Gibson , Combat Afficianado at No 4 ranking W.W. then , blew his airdrums , and buggered off smartly after a flight of that & the unmuffled Folkerts , ST 21/40 . Half the neigbourhood were there on pushbikes before it ( DeH ) Landed . V good for promoteing aeromuddleing . Twins .

SO , Bolton ran C.Case pressure , Big intake . ( maybe the relieved spraybar ? ) & 20 % nitro , for 90 mph in something like a Warlord . /
Here its got Big Intake , Std spaybar . others std intake, relieved spraybar . areas similar but inconsistant , ground to air settings on O% or 5 , though in warm dry weather 5 to 10 is o.k. if the barometers steady . 9 max. 1/4 turn range for useable setting . if youre lucky .
Had a good run with steady weather & regularflying . 90 % good . . . . B u  t .  .   .
But you give up & use ten if the weather & flying is irregular , or loose half the flights with sh*t settings .( and resultant foul moods & iritability )

However . ROSSI R-5 plugs & 20 % Nitro , a 20 second warm up before disconecting electricary from plugs , and 8x6 top flights , see 90 m.p.h. .
and they can hear it at the other end of the valley . A bit of a wail . Though the take off swing can catch you out . Two fast rolls & bores in inverted behind where the pilot was .-  9x4 Top Flights & richening it up , got good take offs , the schedule ( or half of it before the juice is gone . If youre lucky .) And a rich baritone note .

Going to ten gets the schedule if theres only one lap between manouvres , on 80 cc tanks . on a good day .

15 nitro you know the motors wont stop , chunteringing and hissing & banging away through the determined efforts of the gallant airman .
within a turn of something like right , on the needles .

 n~ LL~ VD~

Plastic intakes ( small ) 10 % , were useless - in Melbourne . ( the things flown in dozens of locations ) . Current set up is std. intakes & spaybars. The same in Ea. engine, even . which is farly usefull .
Mufflers when fitted are FOX 19/25/35 , with copper coustom straps . While these arnt ' quite ' its only half as LOUD as the Hot Set Up .

Been Donated three R-3 or R-7  Rossi plugs by Richard justic ,  the 199 mph chap ,current .60 Aus. record holder so theyll go in , for tomorrows efforts . Olde Faithfulle .

despite four wipeouts , through a tree or twoo , and moveing the plywood sheet triggered the 5 ft sq 16 mm plate glass tippiging over , hitting the outer , at the rottenish bit , 7 blowing the Lap Joints on the Spars , Right There . It worst damadge . The rotten shheet from the ' look at the pilot when you let it go ' lauch replaced then . Needed doing anyway . Amougst other things . She aint pretty , but aiborne is .  :!

so SUMMARISEING . it was 60 )z once . . . 55 to 70 ft lines . ( 65 calm , 60 a bit of wind , 55 blowing nicely . ) 9x4s for stunt , 8 x 6s for combat .

toothpick 10 x 5s or thereabouts probly pretty good . A drop of nitro and itll swing anything , the smaller the noiseyer .

Bought the New motor for the Muffler ( Std. Veco - so Ive two Now . But havnt used em )

For S.M.A.E. Combat , or scareing the neighbours , use 20 % , a 8x6 , the big intake ( HERe we get , needs 20 % on Suction , for a good setting )
and pressure .

Was built 2002 & still tatty , Er , Going Well. We Hope . Well see. tomorrow . & I dunno the Brew as its promised bludged fuel as the Train Gestapo dont approve of certain things .

off to think up some more big names .  :X H^^

   All the ones I have see were stock needle and spraybar, and the stock muffler. The only modification is to put baffles on the cylinder fins with dubious effectiveness. All of those I have seen have used standard SIG Champion fuel or similar.

   The engine is really more powerful than you need for a Ringmaster, taming the speed is an issue. It's not as over-the-top too much as a 20/25 FP/LA but we are still talking low 4 second laps on .015x62 and a 9-4.  If you do anything in terms of the venturi, it would be to slightly reduce the diameter. But certainly, run it stock first, and adjust if necessary. Far too many people just jump straight to modifications without ever fully exploring the stock system.

I must admit that the first model I used a Veco .19BB on was an RCM 20 Trainer for R/C.  The engine was awesome in that plane.  Flew usually about 1/2 throttle, not even needing full throttle for take off.  I could close the throttle enough to make the model hover into the wind.  Ended up throwing a rod in that engine.........
