Hello,
Could someone give me very quick run down on the different types of Webra 60.
There is the Speed and the Champion 60, what is the difference?
Can you chose to go with ringed or ABC in either?
Most I have seen come in the black boxes, if it comes in a white and red type box, is it really old or new?
Regards
Rodders

Red B.

Presently the only .60 class engines produced by Webra are the Speed 61F and the Speed 61F Competition. The first one is side exhaust with ringed piston in a steel cylinder and the second one is rear exhaust with an ABC piston/liner.

black boxes are the older ones the red boxes are the newer models.webra had the blackhead 10cc back in the late 60's a powerhouse at the time.it was a loop scavanged engine,had a baffle on the piston.about 1973 plus or minus a year they came out with a new blackhead .61 it was schnurle ported,at the time it had a 1/4-28 crankshaft stud,later it was changed to 5/16 .at the time both were side exhaust ringed engines.

The 1020 is the early cross flow, baffle-piston blackhead:

the 1024 is the side exhaust Speed:

and the 1030 is the rear exhaust Racing:

there is also a 1033 long stroke rear exhaust:

I have the first three (pictured in reverse order).

Thank you all,
It was just what I wanted to know.

Just for your info I have scaned a engine review on Early 60 size engines taken from RCM&E May 1968

It show's that the Early Baffle Piston 61 Webra was very powerful for its time !!!

I have one I bought from the UK for 8 Quid !!! on *bay, it is a very nice engine the one I have is like new and power's a Senoir Falcon like a missile at full Thottle.

I also recall a long-stroke side exhaust type 1027. In the late 1980's when I was trying to learn to fly pattern there were four versions of the front-carburettor, scnhuerle-ported .61 available:

1024 side exhaust short stroke
1027 side exhaust long stroke
1030 rear exhaust short stroke
1033 rear exhaust long stroke

All except 1024 had black cylinder heads. The long stroke versions had a notch machined into the head periphery that made a bright aluminium-coloured ring around the black head. The 1024 engine had a bare aluminium cylinder head, just like the 1024 Webra make today.

Now as to the names: In Webra- speak, it used to be that Speed is a Schnuerle-ported engine (cf. the old 1020 61 mentioned above, which was still available new in the 1980's, vis-a-vis the Schnuerle-ported Speed 61). Racing was a rear-exhaust engine (also Schnuerle-ported of course). F was front-mounted carburettor, R was rear-mounted carburettor. There was a Speed 61R and Racing 61R, which were side and rear exhaust short-strokes with rear mounted carbs and rotary inlet valves in the rear of the crankcase, they were meant for high-revving ducted fan applications. LS, or Champion, was a Long Stroke. I seem to recall they started using the Champion name for the Long-Strokes after Hanno Prettner won the world F3A champs with one in the late 1980's.

So the names back in the '80's were:

1024: Speed 61F
1027: Speed 61F LS Champion
1030: Racing 61F
1033: Racing 61F LS Champion

As far as the boxes are concerned, I seem to recall Champions came in black boxes, the rest in red.

1030 seems to have developed into today's Racing 61F C (1030C) which has larger cooling fins than 1030 but the same 24x22mm bore and stroke.

1027 seems to have developed into today's Speed 70F (1035C) which has the same 25mm stroke but a wider bore and larger cooling fins.

1033 seems to have developed into today's Racing 80F (1039CP) which has the same 25mm stroke but, again, a wider bore and larger cooling fins.

I have a pair of Racing 61F LS (1033) from the late 1980's and the Webra dealer here told me that when I need a piston and liner set I can fit the ones from today's Racing 80, I would think this would work since it has the same stroke, and the bore is only 0.7mm wider than a short-stroke .61 so it's possible Webra haven't changed the outside diameter of the liner, in which case it would fit in the 61 case.

This could also be true of the Speed 61F LS Champion, which could possibly take the piston and liner from today's Speed 70F.

All the above is from memory so I could possibly stand to be corrected. My 1980's Webra catalogues could still in storage somewhere, if anything surfaces I'll repost.

Regards to all.

Edited to add information about ABC versus ring: I seem to recall that you could order any model with a ring setup, or with ABC by adding the letters ABC to the part number, but since ABC was the latest and greatest technology at the time the Champions, which were the competition engines of the time, were usually supplied with ABC.

i have a webra 10 ccm brand new never been run. I would like to sell it for a newer style engine. what is this motor worth

There was also a side exhaust LS. I have three. Two ABC and one ringed. There was a Blackhead Speed side exhaust, maybe heli, model too.

Is Webra still making all the engines shown on their web-site? Is there a US importer?

I think www.paulsmodelsupply.com is the US importer last I heard.

i have a Webra .61 rear exhaust with a red head and Dynamix carb. anyone know about this version and what the actual model is ? is it considered a Webra Speed or competition model.

jatik

Hi,

I think its is Racing as it is rear exhaust with Dynamix... (I have those but with Black head) (See explaning on gkaraolides posting)

rreale,

I believe it is the more modern version of the 1030 or 1033 long stroke RE Webra. Webra started to make red heads later in their production. The 120 also had a red head. I'm not sure that it is a long stroke but I suspect it is as most manufacturers moved to long strokes later in production due to noise issues. But Jari might be right, it could be a "Racing" version for higher RPM than either the "Speed" or the "Competition".

Both the SE and RE engines could and were used in competition it just happened that Webra designated the SE versions as "Speed" while the RE versions as "Competition". Naturally the RE versions were used often in competition models as many of the pattern designs of the 80's used enclosed pipes with RE engines.

Perhaps the red heads were for racing events although I can't see what a Dynamix would do on one in that case. The Dynamix is a rather sophisticated carb mostly used in pattern. Some even had in-flight adjustable high speed needles.

Post some pictures!

Good to have another Canadian round this forum!

Rodders,

I am currently running a Webra Speed .61 which began life as a heli engine but I asked Webra if there was any difference between it and the standard Speed .61. They said that the only difference was the heli cylinder head, so I changed the cylinder head and it's now a great pattern plane engine.

I also have a NIB Webra Speed 61F Champion. Catalog # is: Nr. 1024 RC
It came with the Dynamix carb and a Webra pressure pump installed in the backplate. It is Schnuerle ported and has an oversized 17mm crankshaft. The piston is "ringed", but not baffled.

Here are pics of the red head - not that clear as motor is still in the plane ( a loaded dice II pattern plane ) whci ipciked up recently at a swap meet and am also learning about.

That engine strikes me as a red head long stroke but that's just a "picture guess". It would make sense on a Loaded Dice III.

The old Webra web site is archived and linked here somewhere. A little digging should find it and you should be able to identify the specs on your beast.

Here are a couple of pictures I found of the older RE 61's. The one with the silver ring around the head is the long stroke while the blackhead is the short stroke.

What a shame. Very strong reliable engines. Collectors are now going to run up the prices.
I'm going to hunt for some parts..

At first, becuase of the oversized head,I thought it might have been a Heli- engine. Wasn't sure so I wasn't going to post on it. Then last night I was thumbing through an old RCM magazine and saw it.

The ad is form the May 1992 edition of the RCM mag. It's not theRacing 61F, the ad calls itthe Competition 61. See pic
