Title: Webra 28 Diesel
Post by: Motorman on February 20, 2025, 03:45:00 PM

Anyone know the difference between the webra 28 diesel and the 28 speed version? Did they make a normal version because the speed looks like a regular sport flying type exhaust port. Maybe it's just a name gimmic?

Thanks,
MM :)

Update: Webra "speed" engines are Schneurle ported, as opposed to the Webra Blackhead and Silverline variants that are not.

The pictures of the Webra diesel (Blue anodized head) look just like the Blackhead control line engine I have--except of course the head and the carb. The case looks identical on the outside, including the shape/size of the exhaust port. Mine has 3 bypasses, but I haven't taken it apart to look closely at the ports.
