Gents, for who is interested.

The engine room of the Wester Taurus I detailed for mounting the Webra 6,5 ccm
This engine is about 35, maybe even 40 years old and never run a moment.

The dimensions of the adaptor plate are chosen for the OS Max 61 FX and MVVS 10CCM.

When using the 10CCM engine I have to do this with a light silencer because of the SG, so, only for experimental purposes! (and in the middle of nowhere.)

What would be the noise of the planes of Ed and Les, never seeing they did use a hearing protection equipment, and that without any silencer!
Yèèèssss the good old Taurusses only the weight was few/little!
