Veco 29 engine
« on: February 03, 2016, 07:14:15 PM »
Picked up a (free) Veco 29 engine at our Xmas party, and it was a mess. Over night in the antifreeze filled crock pot got most of the crud off, and Dawn Power Dissolver got the rest.

I can't seem to find much info on this and other forums, so thought I would ask here.

The Veco looks pretty good now, but has a few small dings that won't effect the running. It's not the 29R, but does have an intake sleeve in the venturi. Bottom end appears to be perfect, and has no slop. I've oiled it with 3 in 1 oil, and it has a healthy pop when flipped. Turning it over slowly shows some bubbles around the piston with that light oil, but I think it will run as is.

If it ever stops raining around here, I'm going to run it on the bench.

About what would I expect to see on a Rev-Up 10X6 Pro 3 prop using my standard old engine fuel i.e. Sig 25 percent all Castor, with 10 percent Nitro?

Also, any history, gossip, or any other info on this engine will be appreciated.

Thanks all,

Bill

Does it have the exhaust stack on the "wrong" side, like a K&B Greenhead? If so, that's an early one that was actually made by K&B. If it is and it has an aluminum rod, the rod was cast, and breaks. K&B replaced the cast rod with a steel rod, from what John Hall told me. I had an early Veco .29, and it tossed the rod, many years ago. It was probably 10 years old at the time, and I was in HS.  D>K Steve

Hi Steve,

Long time no see!

Haven't looked inside the case, but the exhaust is on the proper (right) side of the engine. There is carbon on the baffle, so I know it has been run plenty, and likely needs no break in. ;D

Will let you know how it runs, if we ever get a weather break here in Portland.

Ref Anderson's Blue Book:

Early VECOs built by K&B Mfg (1950-1951), then VECO (HECO Mfg - Henry Engineering Company) started in 1953 and back to K&B in 1964.

First year of exhaust on that side is 1956 and called the Mel Anderson designed Series 100 engines.
1957 - Series 100-29 ("29 on case")
1958 - Series 100-29RC
1958 - GP 29R (Rat Race) "R under 29 on case"
1959 - GP 29A (Sport Stunt) no info on case markings

Last year of 29 VECOs is dated 1959.

Thanks Bill,

May get to run the Veco 29 today, as the weather has finally cleared, and warmed up to the low 60's!

Looks like this one is a 1957 build.

Ran the Veco 29 this afternoon, and what a nice surprise it was!  ;D

Ran two tanks of fuel through it, and it started both times on a single back flip of the prop!

With the fuel (Sig 25 percent Castor, 10 percent Nitro) and the prop (10 X 6) mentioned previously it turned 9,500 rpm in a rich 2 cycle, and peaked rich at 10,500 rpm. The surprise was that compression was still very good while hot, and did not seem to change while cooling down.

The previous owner(s) mounted the needle on the right side, and almost directly in the path of the hot exhaust! That will change of course if I run it again, or mount it in an airplane.

Way cool! The 10-6 might be too much load for a .29. I'd look for a 9.5 x 5 or there abouts.

If you put this engine on a provile (sic), then the bottom mounted NV might save some broken needles. Benny Jones does this on all his Ringmasters (which probably number into double digits). With a little work, you could use a ball driver or nut driver to adjust the NV.

Are you going to need a muffler? Scott should be able to produce a tongue muffler for it.  H^^ Steve

Sounds like a strong engine. Comparisons from my bench unmuffed with Sig 5% nitro/25% castor: Torpedo 29S Green Head 10.2k,  low compression McCoy 29 SuperStunt 9.7k, Fox 35 10.5k. McCoy 35RH 10.8k, McCoy 36 SuperStunt 11.2k.

Steve,

Yes, I thought the 10 x 6 might be a bit much, but it seems to turn pretty well on the Veco 29.

We don't have much of a prop selection locally, but I'll look on line for something.

Speaking of props. Master Airscrew is coming out with a new range of wood props in Sept. Here is a what they said in response to my email query.

"As to my knowledge, we have never had smaller than 9inch wood propeller but actually this is one of our new projects. We plan to extend our range of wood props starting with a 7 inch propeller. Unfortunately these will not be available before September 2016."

Yes, Scott is a great source for parts, and a lot of engine info.

I haven't flown muffled engines since I gave up R/C over 10 years ago, but I do see it coming. The Feds tighten their strangle hold on our model activities and our personal lives a little more each day! Doesn't matter that we fly a few hundred feet from a major Freeway (I-5), and the traffic drowns out nearly all model engine noise.


Bill,

Thanks for the info. It's always nice to have a baseline to compare my engines to.

We are only a few feet above sea level at our field in Portland, and that helps performance a bit as well.

Would sure like to have some rpm figures for my Cox 09 Medallions.
The only reviews I've been able to find are for the R/C version. Plenty of info on the TD's, but little on the Medallion.
