RE: Correct MVVS for Cap X
Roger,
The MVVS 35 cc engine would give this model 'scale' power.
However, for 3-D and since your other such plane has the ZDZ 40 cc, I would suggest the MVVS 45 MG for it.
It is very light and will out-power your other model by a very significant margin.
The MVVS 45 cc has a very low level of vibration.
You can go to the [link=http://www.mvvs.cz/]MVVS web site[/link].
Select 'Galerie' on the left then select 'Videogalerie' at the top.
The top clip visualizes this engine running.
