Re: MVVS 2.5 DFS/R
These are really nice engines. ![Smile](https://2img.net/i/fa/i/smiles/icon_smile.gif)
Here is the RC version and a few of the muffler options that they offered;

Re: MVVS 2.5 DFS/R
Unfortunately, they don't make them anymore! I always liked the variety of exhausts they offered.
The castings are superb and I like the style of the NVA - Super Tigre style.

Re: MVVS 2.5 DFS/R
They are indeed excellent running engines. I have the version before the blue anodizing. I got both glow and diesel with throttle, then converted the diesel version to CL by making a venturi and using an OS needle assembly (left). Liked it so much I got another diesel with venturi (and the standard ST-like needle valve) (top).

Re: MVVS 2.5 DFS/R
They are very reliable engines and easy starters. George has a fine collection of 2.5s. I don't think I have the glow version but I should comment and say that from new - you get the option of removing and refitting the cylinder body to change the exhaust position.
Left, right or rear. This is one of my MVVS 2.5s sans adonised head.

Mind you - I know a few who change the cylinder body regularly and it seems to do no harm (but I wouldn't recommend it! Or would I?)
