- A quick look at, and run, of the excellent Webra 40 Black Head, a fantastic crossflow design two-stroke glow engine, which was first introduced in 1971
I picked one up today, look forward to hearing this run. what a unique glow plug !
I love those Webra Engines. Those Engine was the first one i flew, early 2000s, was the old Trainer of my Dad. We also had a 10ccm, wich i still have. I bought it for a few bucks, because i liked the Minivox Silencer wich was mounted. The Engine looked like a piece of crab, but turned out to be a solid and strong runner, 10ccm Blackhead with Dynamix Carb. It was mounted to a 60 sized beat up Trainer. The newer Webras are ven more powerfull, they were real screamers... Had a .60 in a .40size Currare, that thing was a Rocket, 11x7 3/4 Woodprop and unsilenced tuned Pipe......
HP also made really nice engines.
Great engine, have a Webra 61 and some small diesel Webras. All work and I'm using them in different planes. Here in Sweden it's cold now so I envy your nice weather 😒
Hahaha, cold here now as well, filmed this a few weeks back - looking forward to walmer calmer days!!
I had a Webra 61 Blackhead engine in an airplane about 35 years ago. Wonderful running and reliable. I always thought they gave OS a run for the money!! Enjoy your videos.
Thanks for the comment, pleased you liked the video
In our model flying club, we used to run our 6.5ccm Blackheads on a tuned pipe muffler and a 10x6 prop, which gave us about 16.500 rpm give or take. that was in the 1990s. Good times 😊
Yep, great engines
Beautiful engine, I have 2 of the speed gt50h can not believe the level of quality control throughout, they are built like swiss watches
Couldn't agree more!
nice to watch Mark.
Thanks Norm, glad you liked it 😀
Love the engine and the video Mark. Great to hear that girl wind up. Nice job.
Glad you enjoyed it
I bought a TTGP42 and it had a silencer on it which I didn’t recognise. Until now, looks the same as this one! Thanks for helping me ID the silencer!
Glad I could help!
Davvero interessante vedere questi motori che hanno fatto la storia grazie
your welcome, really appreciate the comment
Another blast from the past. Thanks for sharing.
Glad you enjoyed it Terry
I ve got the identical Silverline 410 model, except for silver head, which starts on first flip, here in the Ozarks. I did not know it was so old.
Hi Mark, great to see this old Webra running and yeah they felt always a little bit on the greasy side, but back in ‘93 I had a 20ccm (just came out that date) and it was a brilliant engine👍…just for the 61 sizes I preferred OS max. Cheers from Munich, Sven🍺
I would like that on my Bushwacker plane
Hey Mark!
A little fine tuning, and I'm sure you'll have that thing singing like a bird.
Webra made fine motors. And they were very popular here in the states. I myself have two, a 61 ring, and a Speed 32 with the Dynamix carb.
The 32 was, at the time, the hottest "20 size" motor you could find.
Are you familiar?
Hi Richard, yes, Webra are certainly great engines, I have a couple of the 61 as well, but not familiar with the 32 unfortunately

The Webra Speed .32 ABCD (Dykes ring) was a bit of a late bloomer in the Webra lineup. I bought mine around 1983, I think.
The most interesting thing about this engine is the Dynamix carb. Rather than using a conventional rotating barrel for throttle control, this is a slide-valve carburetor, with an accelerator pump, no less.
When properly tuned (easy to do), the Dynamix carb provides a steady idle with instant acceleration without any hesitation whatsoever. This is a really great engine.
See you in the next one!
What is an idle bar Mark you referred to when you mentioned the plug ? It reved at a high range ok, nice.
With old crossflow engines the glow plug had a bar across the end to protect the element from being flooded out by surges of fuel into the cylinder. You don't see them any more, but they can make a big difference on some old engines. My Merco 61 would not run right without one
@@MarkRobinson555 Those days Schnürrle intake system didn't exist so such idle bars were common. After Schnürrle system applied, bar need eliminated.
how many turn needle high speed for first start? i get this engine last week ago but the engine can't start. i think about the compression. maybe low compression
Take it out 2 - 21/2 turns. Good luck 🤞
When will UA-cam come up with smelly vision 😊
Hahahaha, that would be awesome!
Hi pleas Tell me what size props?
