Engine Weights.
For what it is worth I have just done a weight comparison between my PAW 40 and converted MVVS 40 just to see what the final ready to run dry wieghts would be -
PAW 380 grams
MVVS 395 grams
Both of the engines are sporting their respective mufflers and control line fixed venturis (slightly lighter than an RCcarby).
Now 15 grams of extra porky bits on the MVVS is not a worry and probably comes from the A J Coholic head that is massively built and very strong in design, and I also suspect that the MVVS will be the more powerful.
Does anyone else compare engine weights as part of their criteria of selection?

RE: Engine Weights.
Yes engine weight is always important, and it is the power to weight ratio that one should really look at. It is perhaps even more important in the smaller sizes though, take a PAW09 RC , 127g with muffler, and compare that to an OS .10LA for instance at 154g. That's a weight increase of about 20% with power loss on top of that...
