Let's start a new thread on available engines for CPA. And keep the pattern kits a different issue. All these engines are getting interesting.

What are some of the interesting engines ??Crank

RE: Classic Pattern Engines Available
 

Let's start with engines that we are using now, and what we think about them. Their good points and their bad points. What kind of engine would we like to have. A where we have been able to find them.

Personally there were two engines I preferred, The K & B 61 and the Picco 60. The K & B 61 was a great engine for sport flying. It was inexpensive and parts were plentiful. They still are today. It came with a Perry Carb and was the best of the day. Even though it's not a power house, it would pull a Kaos with plenty of zip.

The Picco was a powerful engine and pulled the heavier pattern planes with some gusto. The inflight fuel mixture control was a big help for tweeking a mixture right before take off. It came in both configurations as rear exhaust and side exhaust.
Others were using the Rossi, Webra and Super Tigre. All great engines.

The worst engine was the Fox Eagle 60. With the bolt on carb you were limited to just the Fox carb that came on the engine. They were big and heavy. That's my opinion. There were some guys that swore by them. Oh, and they were cheap.

I have a Veco .61 that came on a Das Ugly Stick in the early 70's I learned to fly RC with. Don't have the Ugly Stick anymore, but still have the Veco. I had it rebuilt and modified some years ago by a machinest who worked at K&B. He replaced the Perry with a K&B carb. Runs very good and strong and is now on a 30+ year old Sig Kwik-Built Super Chipmunk that I still fly once in a while.

Also, about the same vintage, I have a Super Tigre .60 laying around somewhere. It was piped and used on a Dirty Birdy 60 in regional AMA contests by my instructor before he gave it to me (worn out) and replaced it with a Rossi or OPS.

For the slower lightweight classics like a Kwik Fli, etc. the Enya 60, Veco/K&B 61 and Webra Blackhead. If you want a slower classic go fast and you have retracts the RJL 61 (the old Kraft engine) and the Irvine 61 (Irvine loves a pipe). For classics that preform best at high speed like the Tiporare, Blue Angel and Speeda my choice is the piped OS 61SF-P ABC powerhouse. The Veco/K&B 61 (Twister version) and RJL 61 are available new from http://www.mecoa.com/. All the others are in good supply NIB from that site where you bid on stuff or the RCU Market Place. Used engines that have been run even slightly and then sit for years may need new bearings so keep that in mind. I’ve bought a few used but they did require a bit of work even though they were very clean looking.

Lots of engines available that are period correct and that is one of the cool things about the classics.

RE: Classic Pattern Engines Available
 

The Veco 61, a real work horse and a very dependable engine. It was always a good engine for sport flying. It was never a power engine unless you knew how to work it. Ididn't know they were still available. That's one of the goals of this thread. I remember the RJL, but never had one.

My first engine. McCoy 35 red head bought new for my Sterling Ringmaster.

After having flown various models of the K&B .61/Veco .61, and enjoyed them too, I might add, various OS & Enya 10cc pattern engines and myriad others, my favorite is my Super Tigre G-60 ABC/Ring engine from the late 70's/early 80's. It howls and it just keeps on a howlin'. What a sweet piece of Italian machine work. Sure wish I could find another one NIB.

RE: Classic Pattern Engines Available
 

Along with the K&B and Veco, my favorite is the HB .61 PDP...

Then SuperTigre X and Rossi for the more ballistic ships.

RE: Classic Pattern Engines Available
 

An available engine is the Evolution .61NX. It is very light for the power it makes. Don't run anything more then 15% nitro unless you add a head shim or two. Even 15% could use an extra head shim. Mine on the recommended header, pipe and an 11x7 APC turns 13,800 to 14,000. I don't believe anything that is as light will turn as high.

As to old engines not available anymore, my favorite was the O.S. .61F-SR ABC with the exhaust port raised. Great power for the time. But I have to agree, the Tigre G.60 ABC was a great motor. Glad a have a new one!

RE: Classic Pattern Engines Available
 

That is one sweet looking engine. And MSRP for only $159.00 but sales for about $119.00.

Back on the K&B 61 for a sec....
I have 6 of them....not the Twister model...5 of them were run out and locked up....I bought them over several years averaging $3 each and sent them to Clarence Lee for rebuild and for the PDP mod.
I got a couple of Perry carbs and tossed the K&B carbs.
Right now I have one on a radio test airplane and trainer for friends.
I bought a VECO 61 back in 65' (engine in the pix) when they first came out and I wore it out so many times that I took it to K&B and had a 'max' repair...which was a new engine for $45.
I bought another VECO in 67' and it is still NIB.
A couple of them have the Perry backplate pump with the Perry pump carb and PDP mod. They are pretty strong considering everything.
They run great on 15% nitro and 18% straight castor.
They dont like straight synthetic oil.
Anyway..the rebuild cost averages about $40....git it while you can....I have still another one a guy gave me I need to send in.

I still have the wing from this Kaos and the plans too....it is the original Bridi version I built in 69'....gotta build another fuse and stab.

But....while these engines are plentiful...they probably are a bit too old for our intended use on CPA airplanes.
I'm still for the Rossi/AXI and NovaRossi.

RE: Classic Pattern Engines Available
 

There you go. I have a few of those in my collection and I don't know how I could have forgotten them. They (HB) are sweet running engines.

I keep seeing the K&amp;B/Veco 61's beingmentioned. Clarence Lee still puts together his version of the ckassic K&amp;B .61 with PDP porting. I obtained seveeral of them last year and picked up several used versions by auction. One was an old Veco with his stamp on it that was of the earliest design with the smaller bypass. The best one, which was a more recent Veco with Perry pump carb, turns an APC 11x7 at 13,300 with one of his modified mufflers. His new engines are hand fitted from Mecoa parts and include the new twister style muffler that has an internal baffle. Quiet, butrestrictive. I found the baffle to reduce the rpm on one of the engines by about 500 rpm. The increase in noise when removing the baffle is noticeable, but not too loud.

On the ore ballistic planes, I favor the Rossi. Ialso had luck with the OS VF, but was not as powerful as the Rossi. Interesting thread.

Great thing about some of these (Rossi's, YS's, OS FSR) was the fact that you could run them either fast and in-your-face loud or slow and ez on the ears. Just change the pipe length and prop accordingly.

RE: Classic Pattern Engines Available
 

A good friend of mine bought a Phoenix 8 at our LHS and is letting me get it ready for spring flying. It came with a pumped Enya 60X with a Hatori pipe (I think) setup. Since it was seized up, the LHS owner said to throw that thing away and put an OS, YS or Webra on it. I rebuilt it giving it the crockpot/antifreeze treatment and it came out like new. On the first bench run I achieved 14,200rpm with an 11x7 APC prop and 5% sig fuel. The header appears uncut so I hope to get near 15k rpm when it's tuned. I never thought much of Enya's but after seeing this one run I'm more of a fan.

Other good engines would be the OS FSR series, Webra Speed 60, YS 60 IMO.

RE: Classic Pattern Engines Available
 

I have a NIB G.60R, but I ain't letting go of it :D. I'm waiting for the muse to strike and I'll build a plane just for that engine.

RE: Classic Pattern Engines Available
 

I have always thought the Enya X-series were fantastic engines.

This is a good thread subject.

Iam new to classic pattern so my opinions are not formed by as much experience. That being said I love my OS 61 VF, and Ihad that engine on a Calypso and it went like stink! Unfortunately, the plane was lost, but the engine remains and will find a new home in my T2A MKII. Ialso have a Hanno Special that Irun in my Conquest VI, and that is the best flying airplane Ihave and that includes my 2M ship. I have an NIBOS 61 SF-P ABC that Iam looking forward to putting in the Tipo 750 that Icame into recently.

Josh

P.S. If anyone one knows where Ican get some cores for the Tipo 750, I would appreciate the tip.

RE: Classic Pattern Engines Available
 

I loved the Webra 61 racing rear exhaust with the dynamix carb....I still have one somewhere along with some NIB OS Hanno S , NIB OS 61 SF RF-P , NIB OS 60 FSR ABC , NIB 61 SF side exhaust and others.... great engines !

RE: Classic Pattern Engines Available
 

i love my rossi's all of them the 60.61, and 3+2 long strokes, but i have to say the os sx-wh 61 has some serious grunt as well probably as strong as they come, and easy to buy parts for still, picco's run hard as well not so easy to find or get parts for anymore some ops parts interchange as well sleeves and pistons rods , cranks etc

RE: Classic Pattern Engines Available
 

It is good to see the names of engines other than OS and Rossi mentioned in this thread.

The friend from whom I obtained my Super Tigre G60 ABC?Ring (Jim Emmons), also flew a good variety of engines in pattern. The one that impressed me the most was an OPS Long Stroke. Really serious grunt on low or no nitro fuel and perfect tractability.

I still have two NIB MDS rear exhaust pattern engines to play with, or trade-off. Whatcha got to trade? I only want to trade one of them, if someone is interested. Kits, tools, other engines, all sizes, etc...

RE: Classic Pattern Engines Available
 

MVVS 61 also a good candidate though not exactly freely available these days, they can readliy be had. I have one NIB with an aftermarket YS carb and regulator originally marketed for the Webra Speed - remember those?

I also have matching pipe, curved and straight headers, plus enough spares to rebuild if I wear it out or rotate the exhaust.

DF

RE: Classic Pattern Engines Available
 

Thanks for the reminder. I too have one NIB, along with the factory Diesel head and the tuned pipe and header. Never got around to flying it before my health went South, so to speak.

Mine has a squarish cylinder jug and is a beautifully made engine. I can't remember where I bought it. It might have been Dar Zeelon or Pe Reivers.

How about some pictures of engines and/or engine and airplane setups? I'd like to see some of these.
